BS EN 1627:2011 RC4 single leaf, unglazed
RC4 is the European Resistance Class for sustained, deliberate burglary attacks with heavy electric power tools — drills, angle grinders, percussion hammers — for at least 10 minutes. Above the typical residential RC2/RC3 specs and a step above PAS 24:2022. The certification specifically applies to the single-leaf unglazed configuration. Recognised internationally for premium-security residential applications and high-net-worth household policies.
ISO 9001 certified manufacturing
Every SteelR door is made to order under an ISO 9001-certified quality management system — the international standard for consistent manufacturing process control. Each door's specification, materials, hardware and finish are documented through the full build sequence so the security and finish quality is repeatable across every order.
FIAM678 lock + ISEO R6 PLUS cylinder
FIAM678 three-directional lock (EN 12209 Class 7 — the highest classification for residential cylinder locks) with the ISEO R6 PLUS cylinder as standard. Three-directional locking means the door bolts engage horizontally, vertically up, and vertically down — meaningfully harder to compromise than a standard multi-point shootbolt arrangement. ISEO R6 PLUS is anti-snap, anti-drill, anti-pick to the highest residential cylinder spec.
200+ RAL colours and premium finishes
External face powder-coated in any RAL Classic colour with optional structured, matt or satin finish. Wood-effect transfers (oak, walnut, anthracite woodgrain) available — visually indistinguishable from premium timber or composite at conversational distance. Glazed sidelights, decorative panels and bespoke hardware finishes available so the door doesn't read as an industrial security door.
PAS 24 + Secured by Design + fire-rated options
PAS 24:2022 certified and Secured by Design accredited as standard — the UK police-approved security spec recognised by Hiscox, Chubb, AIG Private Client and other premium home insurers. FD30 fire-rated configurations available where the door also serves as a fire-separation element (relevant for some flats and houses with internal lobbies).
Tiered warranty + Vitrum installation
3 years on the lock mechanism, 5 years on the decorative finish, 10 years on the door construction. Every Vitrum Solutions installation is FENSA registered and covered by a 10-year CPA insurance-backed guarantee on workmanship — separate from and in addition to the SteelR manufacturer warranty. Structural opening survey, weather detailing and finish making-good are all carried out by our own team (relevant on heavier steel doors where opening prep matters).

SteelR — Frequently Asked Questions
What is SteelR?
SteelR is a bespoke UK-made steel entrance door brand. Every door is made to order, ISO 9001 certified, tested to BS EN 1627:2011 RC4 in the single-leaf unglazed configuration — a step above the residential RC2/RC3 specs typical of mainstream steel security doors. PAS 24:2022 and Secured by Design accredited as standard, with FIAM678 three-directional lock and ISEO R6 PLUS cylinder. Available in 200+ RAL colours and wood-effect finishes.
What does RC4 actually mean?
RC4 (Resistance Class 4 under BS EN 1627:2011) certifies a door against a sustained, deliberate burglary attack with heavy electric power tools — drills, angle grinders, percussion hammers — for at least 10 minutes. RC2 (Gerda standard) and RC3 (Gerda Optima/Thermo Premium upgrade) cover lighter attack profiles. RC4 is the spec for higher-risk properties and premium home insurance policies that explicitly require the strictest residential physical-security certification. SteelR's RC4 certification specifically applies to the single-leaf unglazed configuration.
How does SteelR compare to Gerda?
Gerda is the broader Polish-made residential steel security door range — RC2 standard with RC3 upgrade available on Optima and Thermo Premium ranges, four named tiers (ALTUS, THERMO PREMIUM, THERMO PRIME, OPTIMA), strong thermal performance. SteelR is the specialist UK-made bespoke spec with RC4 single-leaf unglazed certification — a step up in physical security at a more bespoke price tier. Choose Gerda where RC2/RC3 is sufficient and the broader range/thermal options matter; choose SteelR where the strictest physical-security certification is the deciding factor or the architectural intent is bespoke UK-made manufacture.
How does SteelR compare to a composite door (Palladio)?
SteelR is meaningfully more secure (RC4 single-leaf unglazed vs Palladio's PAS 24:2022 baseline) and built around a continuous reinforced steel frame. Palladio uses a 65mm GRP fibreglass monocoque slab — different construction priority. Where SteelR wins: maximum physical security, bespoke RAL colour range, premium hardware (FIAM678 lock + ISEO R6 PLUS cylinder). Where Palladio wins: more design flexibility (decorative glazed centre panels, full glass-surround configurations, woodgrain texture) at a more accessible price point. Choose SteelR for security-priority specs; choose Palladio for the heritage/contemporary composite-door aesthetic with PAS 24 security.
What sizes does SteelR come in?
Made to order. Single-leaf doors, double-leaf entrance configurations, and configurations with sidelights and transom panels are all available. The RC4 certification specifically applies to the single-leaf unglazed configuration; glazed and double-leaf variants carry their own certification levels. We confirm the right configuration and certification level for your project at the survey stage.
What is the SteelR warranty?
Tiered manufacturer warranty: 3 years on the lock mechanism, 5 years on the decorative finish, 10 years on the door construction. On top of this Vitrum Solutions provides a 10-year CPA insurance-backed guarantee on the installation workmanship — so the construction (steel, frame, structural integrity) and the workmanship (fitting, weather detailing, opening prep) are both covered for 10 years from installation.
Is SteelR available in any RAL colour?
Yes — full RAL Classic palette for the external powder-coated finish, with optional structured, matt or satin finish. Wood-effect transfers (oak, walnut, anthracite woodgrain) available — visually indistinguishable from premium timber or composite at conversational distance. Internal finish options include matched RAL or contrasting colour. Hardware finishes include polished chrome, brushed stainless, brass, antique brass and matte black.
Will my insurer recognise SteelR?
Yes — RC4 (BS EN 1627:2011) is the strictest residential physical-security certification UK insurers look for. Several premium home insurance underwriters (Hiscox, Chubb, AIG Private Client) explicitly require RC2+ on the front entrance of premium properties — RC4 exceeds this requirement comfortably. We supply the BS EN 1627 test certificate and FENSA installation documentation as part of the installation paperwork.
Do you install SteelR across the Home Counties?
Yes — Vitrum Solutions installs SteelR across Buckinghamshire, Berkshire, Oxfordshire, Surrey, Hampshire, Hertfordshire and West London. Including Beaconsfield, Gerrards Cross, Marlow, Windsor, Ascot, Virginia Water, Weybridge, Cobham, Esher, Henley-on-Thames, St Albans and the surrounding premium towns where bespoke steel entrance doors are most often specified.
