All FBS steel door sets are RC2 rated as standard under BS EN 1627:2011, meaning they resist 3 minutes of skilled tool attack. Our Athens model is RC3 rated — suitable for higher-risk applications. All door leaves, frames, and cylinders are independently tested and certified as a complete set.

Yes. Every frame in our steel door range uses a polyamide thermal break bar, which eliminates the cold bridge between the inner and outer steel sections. This delivers a U-value of ≤ 1.0 W/m²K — compliant with current Building Regulations Part L requirements for new dwellings.

Yes. All door leaves and frames are powder-coated to order, which means any RAL or BS colour is available at no additional cost for standard orders. For projects requiring multiple doors in the same colour, we can batch-coat to ensure consistency across a development.

Stock colours (Anthracite Grey, Jet Black, White) are typically dispatched within 5–7 working days. Custom RAL orders and bespoke sizes carry a 15–20 working day lead time from order confirmation. Large-project volumes should be discussed with our trade team to plan phased delivery.

Yes. Every set is supplied with a 5-point multipoint lock body and a tested anti-drill, anti-pick cylinder. The cylinder is keyed to differ as standard — master key suites are available for multi-door residential and commercial projects. Specify on your order form.
