1. Bradbury Group

Company Overview

  • Address: 6 Atkinsons Way, Foxhills Industrial Estate, Scunthorpe, North Lincolnshire, DN15 8QJ, United Kingdom
  • Website: bradbury-group.com
  • Date Established: 1991

When I first came across Bradbury Group, what struck me wasn’t just the size of their facility. It was how clearly they had built their business around real needs, not just products. You can tell when a company listens to its customers, and Bradbury feels like one of those.

They’ve been making steel doors since 1991, and it shows. From fire-rated doors to heavy-duty security units, they know their stuff. But more than that, they’ve figured out how to balance quality with speed.

That’s not easy, especially when the projects are big and the stakes are high.

If you’re managing a site or building with tight specs, it’s good to know someone’s done the homework for you. Bradbury has. And they’re still improving, which says a lot.

Key Products

  • M2M+: A solid, everyday steel door that covers most general needs. It works well in everything from offices to warehouses, and you don’t have to overthink it.
  • M2M2 / M2M3 / M2M4: These are the ones you want for serious security. With ratings up to SR4, they’re built to take on real threats, not just tick boxes.
  • M2MFD: This model is all about fire safety. It’s tested and certified to hold for up to four hours, which makes it ideal for schools, hospitals, and similar sites.
  • M2MAC: A soundproof option that doesn’t skimp on protection. It’s great when you need both noise control and top-tier security in one solution.
  • ClassicAL: A smart aluminium door that’s secure and sustainable. It’s made from recycled material and works well for communal or residential access points.

Certifications and Compliance

  • LPCB LPS 1175 (SR2 to SR5): Tested to resist serious attacks, which is essential for high-security areas.
  • LPCB LPS 2081: Useful for environments where stealth tools might be used, like apartment entries or public buildings.
  • CERTIFIRE: Confirms the fire safety claims. You know what you’re getting, and it’s been tested properly.
  • CE Marking: Assures the product is legally fit for use across Europe.
  • Secured by Design: A police-backed stamp that adds confidence, especially for public contracts.

Services Offered

What I like about Bradbury is they don’t just ship you a door and call it a day. Their M2M+Express service is perfect for last-minute or emergency replacements. You can get a custom steel door made and dispatched in three to five days.

Plus, their online door builder makes life easier. No long email chains or waiting for quotes. You choose what you need, get your price, and move on. For busy teams or fast-moving projects, that kind of system is a relief.

Key Takeaway

Bradbury is dependable, well-certified, and able to move quickly when it matters most. If you’re working with tighter budgets or need more niche specs, you might find the lead times or custom options a bit limited.

2. Strongdor

Company Overview

  • Address: Unit 4 Southgate, White Lund Industrial Estate, Morecambe, LA3 3PB
  • Website: strongdor.com
  • Date Established: 2008

The first time I saw Strongdor’s branding, I remember thinking, “These people really care about the details.” It’s not just the doors, it’s the way they show their factory, spotlight their team, and even put out things like a “101 Little Things” brochure.

You don’t do that unless you’re proud of your work. Strongdor comes across as honest, grounded, and incredibly customer-focused. They’ve built their reputation around quick response times, reliable lead times, and solid quality control.

That kind of consistency is refreshing, especially if you’ve ever dealt with flaky suppliers.

They’re not the biggest name in the steel door world, but they’re one of the most likable and transparent. If you’re looking for a company that’s easy to work with and delivers what it promises, Strongdor belongs on your list.

Key Products

  • Steel Doors: These are the workhorses of their lineup. Fully bespoke, suitable for internal or external use, and upgradable with acoustic ratings up to 39dB. Clean, simple, and functional.
  • Firedor: Their custom fire-rated doors. These are built to meet demanding fire protection specs and give you peace of mind in high-risk environments.
  • Acoustic Doors: Some of their models reach up to 56dB, which is serious sound control. If noise is a factor in your building, these doors are worth a closer look.
  • Steel Security Doors: Rated from SR1 to SR4, with full PAS24 and SBD certification. A solid choice for projects that demand more than just basic protection.
  • Louvidor: Louvred steel doors and panels for when you need airflow without giving up strength. They’re great for utility rooms or HVAC spaces that need both ventilation and security.

Certifications and Compliance

  • ISO 9001: Their quality management system is certified, which adds confidence in both process and output.
  • Secured by Design (SBD): Police-endorsed certification that strengthens their value in public and commercial projects.
  • PAS24: Confirms their products meet security standards for doors in the UK.
  • LPCB (SR1 to SR4): These ratings prove they’re serious about resisting intrusion and meeting formal security requirements.

Services Offered

Strongdor makes the buying process feel easy. They promise industry-beating lead times, and from what I’ve seen, they follow through. Their quotes come back quickly, their team communicates clearly, and they don’t leave you guessing.

They also show up in the community. Whether it’s charity work or employee features, their messaging feels human, not corporate. That goes a long way when you’re working on repeat projects or need support down the line.

Key Takeaway

Strongdor stands out for its friendly service, fast lead times, and fully bespoke steel door options. The only thing to keep in mind is that their physical address isn’t readily available, which may feel less accessible for buyers who prefer in-person visits.

3. Latham’s Steel Security Doors

Company Overview

  • Address: 35–37 Hainge Road, Tividale, Oldbury, West Midlands, B69 2NY
  • Website: lathamssteeldoors.co.uk
  • Date Established: 2011

What caught my attention about Latham’s was how quickly they can get a door out the door, no pun intended.

When most suppliers are quoting long lead times, they’re pulling certified security doors straight from stock and getting them shipped fast. That’s rare, and honestly, it solves a real headache for contractors and facilities teams.

Their approach is more like a ready-to-go warehouse than a slow, made-to-order model. But they’ve managed to pair that speed with some seriously solid product certifications. That’s not a combination you see every day, especially in the security door space.

If you’re working on a project with a tight timeline or need a replacement in a hurry, Latham’s might just be the fastest route to a compliant, high-security solution.

Key Products

  • Steel Security Doors: These are the core of their offering. Solid, stocked, and certified, they’re built for rapid turnaround without cutting corners.
  • Fire Exit Doors: Ready-made emergency exits that meet fire safety regulations. Ideal for quick installations across commercial or industrial settings.
  • Glazed Doors: Let in natural light without sacrificing durability. A smart pick for internal office fit-outs or building entrances.
  • Acoustic Doors: These reduce sound transmission where noise control matters. Great for schools, studios, or offices near heavy traffic.
  • Panelled Steel Doors: Aesthetic steel doors that blend into more decorative environments. They offer the look of timber, with all the benefits of steel.
  • Louvred Doors: Provide airflow without giving up security. Perfect for plant rooms or utility spaces.
  • HOOPLY™ 19-Point Locking System: Fitted to their personnel doors, this is a standout feature. It boosts security while still being user-friendly.
  • Accessories: From panic bars to frame extensions and replacement parts, their hardware range means you can get everything in one order.

Certifications and Compliance

  • ISO 9001:2015: Quality management is locked in.
  • ISO 14001:2015: They’re keeping environmental practices in check too.
  • ISO 45001:2018: Shows they take workplace safety seriously.
  • LPCB Certified: Adds credibility for high-security applications.
  • Warrington Fire (Certifire & Certisecure): Critical for trusted fire and security door compliance.
  • Secured by Design (PAS 24 & STS202 BR3): Police-backed approval. Always a plus for public or private projects needing extra peace of mind.

Services Offered

What makes Latham’s stand out is how much they keep on hand. They claim to be the first in the UK to hold both certified security and fire-rated steel doors in stock. And it shows. You can find what you need and get it delivered without waiting weeks.

They also offer modification services if a stock door isn’t quite the right fit. So you can get fast delivery and still have something customized to your needs. That balance of speed and flexibility is a major win, especially for mid-sized projects or urgent repair jobs.

Their website is well-organized too. You can browse by door type, view transparent pricing, and even order online without having to chase down a quote.

Key Takeaway

Latham’s offers unbeatable speed, a huge range of stocked products, and full certification coverage across fire, security, and quality standards. The one limitation is that if you need something highly bespoke or unusual, you may be better off with a made-to-order supplier.

4. Metador

Company Overview

  • Address: Britannia House, John Boyle Road, Middlesbrough, TS6 6TY
  • Website: metador.com
  • Date Established: 2004

Metador gives off the vibe of a company that’s proud to build things that last. From the moment I saw their Defender product line, I could tell this wasn’t just about security. It’s about performance, detail, and making sure your building gets the exact door it needs.

They don’t just make doors. They work with you to design solutions that solve real problems—whether that’s fire safety, sound control, thermal insulation, or all of the above.

Their team takes a “never say no” approach, which is rare and honestly refreshing.

There’s a quiet confidence in how they operate. No flash, no fluff. Just doors that perform and a process that feels flexible and smart.

Key Products

  • Defender Fireshield: A tough lineup of fire-rated doors with E30 through E120 ratings. These give you the freedom to spec the right level of protection, based on actual risk.
  • Defender Xtraguard: These are your high-security options. They come rated all the way up to SR4, which means they’re built to handle serious threats.
  • Defender Soundguard: Great for projects where sound control matters. Clean design with a sharp acoustic performance.
  • Defender Thermaguard: Built for energy efficiency, with U-values as low as 1.4. These are great for keeping heat in and bills down.
  • Specialty Products: They offer stainless steel finishes, woodgrain coatings, sports hall doors, riser doors, and more. That range makes them surprisingly versatile.

Certifications and Compliance

  • PAS 24: Proves the doors meet UK security requirements for entry doors.
  • LPCB SR2, SR3, SR4: These ratings confirm the Defender range is tested against real intrusion threats.
  • Fire Ratings (E30 to E120): Ensures their Fireshield range can hold up to high heat and fire exposure for defined periods.

Services Offered

What stands out most with Metador is how collaborative they are. If you’ve got a non-standard requirement, they won’t shut it down. In fact, their entire workflow is built around making your design work.

They keep the quoting process quick, they send regular order updates, and they only work with approved installers. That level of control makes a difference when timelines are tight and spec errors can cost you.

From the first call to the final delivery, they try to keep things straightforward and customer-friendly.

Key Takeaway

Metador brings high-spec design, a flexible team, and deep product performance into one complete package. The one drawback is that they don’t showcase their full certification list upfront, which might slow things down for formal bid processes.

5. Robust UK

Company Overview

  • Address: Coaldale Road, Lymedale Business Park, Newcastle-under-Lyme, Staffordshire, ST5 9QX
  • Website: robust-uk.com
  • Date Established: Around 1999 (25 years of experience)

The thing I immediately noticed about Robust UK is how clear they are about who they serve. This is a company built for the trade. Not retail, not general business customers, just professionals in the construction world who need reliable steel doors, fast and fully fitted.

They’ve been at it for 25 years and it shows in the way they’ve shaped their factory and service model. Their doors arrive on site fully assembled, with hardware already installed.

That might seem like a small detail, but it makes a huge difference to time on site and reduces the chance of errors.

Robust UK doesn’t try to be everything to everyone. They’ve doubled down on being the go-to supplier for installers, contractors, and fit-out specialists. And honestly, they do it well.

Key Products

  • Fire-Rated Doors: Built to handle the heat, literally. These are fully certified and designed to meet fire safety standards for commercial builds.
  • Security Doors: A strong range that adds serious peace of mind. Ideal for places where break-in resistance is non-negotiable.
  • Glazed Steel Doors: For when you want a mix of visibility and durability. These are popular in offices and public access areas.
  • Louvred Doors: Allow airflow while maintaining a solid steel structure. Great for plant rooms or back-of-house spaces.
  • Customised Doorsets: Everything is made to order, so you’re not locked into a one-size-fits-all setup.

Certifications and Compliance

  • Exova Warringtonfire & BM Trada: Trusted names in fire testing. You know your fire-rated doors are backed by real data.
  • Secured by Design: A key win for public sector jobs or residential fit-outs with strict security needs.
  • ISO 9001: Ensures their factory is running on a solid quality management system.
  • CHAS, Achilles, Constructionline: All the badges that matter when you’re tendering or working through large frameworks.

Services Offered

This is where Robust UK really sets itself apart. Every door they ship comes fully assembled. That means all the locks, latches, closers, and handles are already installed. You don’t have to waste hours on site trying to figure out what goes where.

They also include a fitting kit with every job. Fixings, touch-up paint, even mastic. That kind of detail shows they’ve thought about the install process from the installer’s point of view.

And if you’re using Magnelis® steel, you can get up to a 10-year anti-corrosion warranty. That’s not just marketing—it’s peace of mind that lasts.

Key Takeaway

Robust UK is a solid fit for trade professionals who want factory-finished doors, easy installs, and strong warranties. The only limitation is that their trade-only model might not suit businesses looking to buy directly without a construction partner.

6. Rotec Security Solutions

Company Overview

  • Address: Lytham Drive, Bramhall, Stockport, SK7 2LD
  • Website: rotecsecurity.co.uk
  • Date Established:1979

Rotec is one of those companies that feels built for the big stuff. When I first came across their name, what stood out wasn’t just the spec sheets, it was the sheer volume they can handle. We’re talking over 1,500 doors and entrance systems per month. That’s serious production power.

They clearly lean into large-scale commercial and infrastructure projects. And it shows in how they approach things.

Their team gets involved early, not just at the install phase. They want to help shape the spec, align with your build plan, and make sure it all fits together smoothly.

If your project has tight timelines, serious compliance needs, or just a lot of doors to manage, Rotec brings the experience and capacity to handle it without blinking.

Key Products

  • Security Steel Doors: These are tested and certified all the way up to LPS 1175 SR4. That makes them a strong choice for high-risk zones like utility facilities or data centers.
  • Fire-Rated Steel Doors: Designed for compliance and protection. You get safety without sacrificing durability or looks.
  • Acoustic Steel Doors: A solid option for performance environments, studios, or offices where sound control is non-negotiable.
  • Glazed Doors and Screens: Available in both steel and aluminium. Great for modern builds that need visibility and airflow without losing integrity.

Certifications and Compliance

  • LPCB & PAS24: Security certifications that confirm serious intrusion resistance.
  • Secured by Design: Ideal for public-sector bids and sensitive-use projects.
  • ISO 9001: Assures clients the quality systems are in place.
  • ISO 14001 & ISO 45001: Environmental and health and safety standards are covered.
  • CHAS & Constructionline Gold: These make a difference for prequalification and supply chain approval.
  • SSIP Acclaim: Adds to their credibility with health and safety schemes.
  • Carbon Neutral Britain Certification: A standout for ESG-conscious buyers. You don’t often see this level of commitment in door manufacturing.

Services Offered

What I like most about Rotec’s model is how hands-on they are from the start. They don’t wait for the drawings to be final. Instead, they get in early, help shape the design, and offer product choices that match up with site requirements.

From there, they take care of the full package. They’ll design it, supply it, and install it—so you’re not chasing multiple vendors for answers. It’s a smooth process and that matters when you’re running a large job with tight coordination.

They’re also experienced with complex sites, which means they speak your language when it comes to deadlines, logistics, and onsite realities.

Key Takeaway

Rotec is built for big projects, with high-volume capability, tight certification coverage, and a truly full-service model. The only downside is that their scale and focus might be overkill for smaller, one-off builds with simple door needs.

7. Kirncroft Security Doors

Company Overview

  • Address: Wadworth Hill, Burstwick, Hull, East Riding of Yorkshire, HU12 9EY
  • Website: kirnsecuredoors.com
  • Date Established: Over 20 years ago

When I think of Kirncroft, the first thing that comes to mind is practicality. This is a manufacturer that isn’t trying to impress with buzzwords or fancy certifications. They just focus on building strong, affordable steel doors—and getting them to you fast.

With a 10,000 m² facility in Hull and decades of experience, they’ve made a name for themselves by serving a very specific market.

If you’re in modular construction or working with anti-vandal units, you’ve probably already come across their products.

It’s not a bells-and-whistles brand. It’s a “get the job done without delay” brand. And in a fast-paced sector, that’s exactly what a lot of buyers are looking for.

Key Products

  • 10-Point Locking Steel Security Doors: This is their flagship product. Built from heavy gauge galvanized steel with reinforced construction, it’s tough, simple, and ready to go.
  • Fire-Rated Doors: Offers an added layer of protection while sticking to the same durable and budget-friendly design approach.
  • Fire Exit Doors: Functional and fast to install. Great for portable or modular buildings where compliance and convenience go hand in hand.
  • Anti-Vandal Shutters and Louvres: Designed to protect windows and vents. Ideal for containers, site buildings, or temporary setups.

Certifications and Compliance

  • Fire Protection Association (FPA) logo shown: Indicates a level of fire safety focus, though specific details aren’t deeply promoted.
  • No LPCB, PAS24, or SBD security ratings on standard doors: Instead, their claim is based on physical toughness and in-house engineering.
  • 2-Year Product Warranty: A simple but solid assurance that they stand behind what they build.

Services Offered

Kirncroft is built for speed and volume. They claim to hold one of the largest inventories in the UK, and for customers who need a door tomorrow, that’s a huge advantage.

Their “down to the last screw” quality check system might sound like a slogan, but it’s part of how they’ve earned trust in the modular building space. Everything shows up ready to install, and you don’t have to chase missing parts or fix sloppy welds.

For urgent site work or container fit-outs, their same-day dispatch option is a genuine lifesaver.

Key Takeaway

Kirncroft delivers fast, rugged steel doors that are ideal for modular and anti-vandal builds that last a long time. Just keep in mind that if your project demands high-security certifications, this may not be the right fit.

8. The Steel Door Company

Company Overview

  • Address: Unit 8 Brookmead Industrial Estate, Telford Drive, Tollgate Industrial Estate, Stafford, Staffordshire, England, ST16 3ST
  • Website: steeldoorcompany.co.uk
  • Date Established: Not specified

When I first came across The Steel Door Company, it was obvious they weren’t aiming for industrial fit-outs or commercial bulk orders. Their world is clean lines, high-end design, and finishes that look more like furniture than hardware.

They’ve carved out a spot at the top end of the market by leaning hard into minimalism and customization. Whether it’s a single interior door or a full glass wall system, everything is made to look sharp and feel seamless.

The steel profiles are just 20mm thick, which is incredibly slim and allows for more glass, more light, and more wow factor.

If your project calls for aesthetics first and performance second, this is one of the few UK manufacturers that fully owns that lane.

Key Products

  • Single & Double Doors: Beautiful, minimalist steel-framed doors that feel more like architectural features than traditional security units.
  • Sliding Systems: Space-saving and sleek, with clean tracks and uninterrupted lines. A go-to choice for premium interiors.
  • Side Screens & Over-Panels: These extend the visual impact of a door and allow for light to flow through more of the space.
  • Customisation Options: Every part is made to order. Choose your finish, glass type, and hardware for a look that fits your exact vision.

Certifications and Compliance

  • No fire or security certifications listed: This is not a downside if your focus is residential aesthetics over commercial compliance.
  • The emphasis is on craftsmanship and visual appeal: These doors aren’t tested for attack resistance or fire containment, because that’s not their purpose.

Services Offered

One thing that really stands out is their use of an in-house fitting team. Most companies hand off installation to a third party. These folks don’t. Their fitters have done over 1,000 installs across the UK, which helps keep quality consistent from start to finish.

The whole process is consultative. From the first sketch to final installation, they work closely with designers, architects, and homeowners to make sure the final product matches the vision. It’s not about volume, it’s about experience.

And if you’re someone who cares about clean details and aligned finishes, that kind of hands-on attention makes a big difference.

Key Takeaway

The Steel Door Company delivers beautifully crafted, ultra-slim steel doors made for luxury homes and designer spaces. But if your project requires fire ratings or high-security specs, their doors likely won’t check those boxes.
