Construction & Materials
BF S20 is fabricated from cold-rolled steel profiles using CNC cutting, drilling, bending and welding. Visible sightline is 20 mm, the door leaf profile 20 × 42 mm, with a 44 mm overall frame depth and 40 mm frame height. Hinges are welded; glazing beads are mechanical click-on aluminium.
Glass & Glazing Bars
Glass from 4–8 mm in clear, textured, fluted, frosted and privacy options. Glazing bars are welded or applied, with nearly unlimited custom layouts. Single-glazed, interior only — not thermally broken and not fire rated.
Finish
Powder coated in standard, premium or fully custom RAL colours. Matte black is our standard; any RAL is available, with the upcharge shown in the running total as you select it.

Choose your handle
The one part of the door you touch every day. Levers for swing doors, pulls for sliding and pivot.

Handing determines which side the hinges sit on and which way the door swings.
Viewed from the pull side of the door. Final handing will be confirmed during shop drawings.
Choose your finish
Powder-coated steel in matte black, white, or any RAL colour.
