Whether it is a plant room door taking daily impact from trolleys and pallet trucks, a rear yard entrance that has to resist forced entry, or a fire-rated escape door that must perform without fail, a well-specified steel door earns its keep for decades if it is installed and maintained properly. We supply, install and service steel doors across Peterborough, London and nationwide, working with facilities managers, contractors and business owners who need doors that simply do their job without drama. Not every steel door is the same, and this is where a lot of buyers come unstuck. Gauge of steel, core fill, hinge specification, lock type and frame construction all vary hugely between a budget personnel door and a certified security or fire door, yet from the outside they can look almost identical. We talk buyers through what they actually need for their application rather than what is easiest to sell, because a door that fails a fire inspection or gets kicked in within a year is a false economy however cheap it looked on the invoice. As a family-run business with over 60 years of combined engineer trade experience across our team, we have fitted and repaired steel doors in warehouses, schools, retail units, plant rooms, communal blocks and industrial yards. That breadth of experience means we recognise the common failure points before they become a call-out, and we specify accordingly at survey stage rather than after something has already gone wrong. Every steel door we supply and install carries our 12-month warranty, and we are fully insured with £10,000,000 public liability and £10,000,000 employers liability cover, so contractors and facilities teams can bring us onto site with confidence. Site surveys and quotations are always free, and we never quote blind over the phone because door specification genuinely depends on the opening, the usage and the risk profile of the site. ### Facilities and estates managers Steel doors covering plant rooms, service risers, external stores and staff entrances that need to be secure, durable and compliant, with planned maintenance to keep them that way across a portfolio of buildings. ### Warehouse and industrial operators Personnel doors and security doors that survive daily contact with forklifts, cages and pallet trucks, plus fire-rated doors protecting escape routes and compartmentation within larger sheds and units. ### Landlords, developers and main contractors New-build and refurbishment projects needing steel doors specified, supplied and fitted to programme, with certification paperwork and RAMS provided on request for principal contractors and building control. What it costs to leave it ## What happens when steel doors are wrong, worn or ignored A steel door looks tough, which is exactly why problems get missed until they are serious. Corrosion, misalignment and worn ironmongery all creep up quietly on a door that appears fine from a distance. ### Failed security A steel door with a worn lock, dropped hinges or a distorted frame no longer closes flush or latches properly, giving intruders an easy point of entry despite the door looking solid and imposing. ### Fire compliance failure Fire-rated steel doors depend on intumescent seals, correct hardware and a door that closes and latches fully every time. Damage, incorrect hardware substitutions or a door propped open routinely can invalidate the fire rating entirely. ### Costly reactive repairs Small issues like a sagging hinge or surface corrosion, if left, spread into frame distortion, sticking leaves and locks that need replacing rather than adjusting, turning a simple job into a full door and frame renewal. ### Mistakes we get called out to fix - Buying a generic steel-faced door for a fire-rated opening without checking it actually holds a certified fire rating. - Ignoring surface rust because the door still opens and closes, allowing corrosion to spread into the core and frame. - Fitting the wrong hinges or closers for the door weight, causing early sag and misalignment. - Letting non-accredited tradespeople carry out repairs on fire doors, which can invalidate certification without anyone realising. - Assuming all steel doors need no maintenance because they look robust, when hinges, seals and locks all wear with use. - Leaving damaged doors in service after an impact because the door still shuts, without checking frame square and latch engagement. Our process ## How we handle a steel door project 1. Step 1 ### Free site survey We visit the site, measure the opening, assess the frame and existing structure, and discuss what the door needs to achieve, whether that is security, fire rating, insulation or simple durability. 2. Step 2 ### Specification and quote We recommend a door specification suited to the opening and usage, covering gauge, core, ironmongery, certification and finish, and provide a clear, itemised, no-obligation quotation. 3. Step 3 ### Manufacture and scheduling Once approved, we order or manufacture the door and frame to the agreed specification and book an installation date that works around your operational hours where possible. 4. Step 4 ### Installation Our CSCS card holding engineers remove the old door where applicable, fit and align the new frame and leaf, install ironmongery and closers, and test operation and closing action thoroughly. 5. Step 5 ### Handover and aftercare We hand over any certification documents, explain maintenance requirements, and offer a planned maintenance contract to keep the door compliant and operating correctly, backed by our 12-month warranty. What you get ## Why choose Argents for steel doors ### Right door for the risk We specify to the actual application, whether that means a certified fire door, a high-security personnel door or a simple robust store door, rather than a one-size-fits-all product. ### 12-month warranty Every steel door we install or repair is covered by our 12-month warranty on parts and workmanship, giving you a clear guarantee behind the invoice. ### Fully insured We carry £10,000,000 public liability and £10,000,000 employers liability insurance, so you can bring us onto commercial and industrial sites with confidence. ### Accredited engineers Our CSCS card holding engineers work to BM TRADA / FIRAS standards on fire door work, and we are SafeContractor accredited for site safety management. ### Free, honest surveys Every quote starts with a free site survey. We tell you what the door genuinely needs rather than upselling or underselling the specification. ### Nationwide reach, local presence Based across Peterborough and London, we cover Cambridgeshire, Bedford, Leicester, Milton Keynes, Northampton, Hemel Hempstead, Watford and further afield nationwide. In detail ## Steel doors in detail Steel doors cover a wide range of products behind one simple description. Getting the right one for your building means understanding materials, certification and how commercial requirements differ from residential ones. ### Materials and construction A steel door is built from a galvanised or mild steel outer skin wrapped around a core, and the core is where most of the meaningful difference lies. Fire-rated doors typically use a mineral-based or honeycomb core engineered to hold its integrity under heat for a specified period, while security doors may use a denser core or internal reinforcement plates around the lock and hinge zones to resist drilling and prising attacks. Insulated steel doors use a foam or mineral wool core to improve thermal performance for external openings on heated buildings. Frame construction matters just as much as the leaf itself. A steel door hung in a timber or thin-gauge frame will never perform to its full potential, whether that is security or fire resistance, because the frame is usually the weakest point in an attack or the first place a fire-rated assembly fails. We specify matching steel frames, correctly fixed into the substrate, with intumescent seals fitted where fire performance is required, so the whole assembly performs as a certified unit rather than a door that happens to be steel. ### Security specification For sites where security is the primary driver, we look at the full opening rather than just the door leaf. Multi-point locking, anti-tamper hinge pins, hinge bolts, and reinforced strike plates all contribute to resistance against forced entry, and the right combination depends on the level of risk at the site and any insurance requirements attached to the building. Some premises need doors rated to specific attack test standards, particularly where valuable stock, cash handling or sensitive equipment is on the other side. We also consider how a security door is used day to day. A door that is propped open constantly for staff convenience defeats its own purpose, so we discuss access control options such as coded entry, fobs or automatic closers where appropriate, so the security specification survives contact with real working habits rather than existing on paper only. ### Fire-rated steel doors Fire doors have a specific job: to hold back fire and smoke for a defined period so people can escape and fire services can respond. A genuine fire-rated steel door is tested as a complete assembly, meaning the leaf, frame, hinges, seals and any glazing must all be part of the certified specification. Substituting a single component, such as fitting the wrong hinges or removing intumescent strips during a repaint, can invalidate the whole certification without any visible change to the door. We work to BM TRADA / FIRAS standards on fire door installation and repair, and we can supply full certification paperwork for building control, insurers or fire risk assessments. For sites managing multiple fire doors, we recommend planned inspection visits, because fire door regulations increasingly expect documented evidence of routine checks, not just an assumption that the doors are fine. ### Applications and industries Steel doors turn up across almost every type of commercial and industrial building we work on. Warehouses use them for personnel access alongside roller shutters, protecting stock and staff areas. Plant rooms and service risers use fire-rated steel doors to maintain compartmentation. Retail units use steel doors for rear-of-house security. Residential blocks use fire-rated steel doors on flat entrances and communal escape routes, where regulation is particularly strict following recent changes in fire safety legislation. Education and healthcare sites often need a combination of fire rating, vision panels for supervision, and robust ironmongery that withstands high footfall, while industrial units may prioritise raw durability and security over aesthetics. We size the specification to the actual environment rather than defaulting to the same door across every project. ### Commercial versus residential requirements Commercial and industrial steel doors are typically specified for higher usage cycles, heavier impact loads and stricter compliance obligations than residential doors. A warehouse personnel door might be opened hundreds of times a day and needs hardware rated for that duty cycle, whereas a residential fire door on a flat entrance is used far less frequently but still carries the same non-negotiable certification requirements around escape safety. Commercial sites also tend to need documented evidence: certification, RAMS, maintenance records and sometimes insurer sign-off, all of which we can provide. Residential and smaller commercial jobs may simply need a reliable, secure door fitted correctly and explained clearly, without the same paperwork trail, and we adjust our approach to match what the site genuinely requires.
