Common Questions

Frequently Asked Questions

What is RK Steel and what is it used for?+
RK Steel is a range of handmade steel-framed doors, windows, and glass partitions with ultra-slim 20mm profiles. They are used for both internal applications (room dividers, partitions, internal doors) and external applications (steel windows and entrance doors), offering a contemporary Crittall-style aesthetic.
Can RK Steel be used for both internal and external applications?+
Yes. The internal range includes partitions, room dividers, and doors in hinged, pivot, sliding, bi-fold, and pocket configurations. The external range includes steel windows and doors that are PAS24 and Secured by Design certified for full weather and security performance.
Is RK Steel available with a fire rating?+
Yes, RK Steel offers FD30 fire-rated glass options, making it suitable for applications where building regulations require fire-resistant partitions or doors. This is particularly useful in loft conversions, commercial fit-outs, and open-plan renovations.
How does RK Steel compare to traditional Crittall?+
RK Steel achieves the same industrial-chic aesthetic as Crittall but with modern manufacturing techniques and performance standards. The 20mm steel profiles are slimmer than many Crittall alternatives, and the range offers PAS24 security certification, 36dB acoustic glazing, and designer colour collections from Farrow & Ball and Little Greene.
What maintenance does RK Steel require?+
RK Steel is constructed from high-tensile galvanised steel, which resists corrosion and rust. The powder-coated finish is durable and long-lasting. Regular maintenance simply involves wiping down with a damp cloth. All glazing is dry-beaded with gaskets, making glass replacement straightforward if ever needed.
