Creating Bespoke Steel Windows and Doors

The use of galvanised steel as the material of choice for windows and glazed doors is a traditional and historical choice, which increased dramatically during the last half of the 19th century during the industrial revolution.

The Galvanised Steel profiles used in Secco windows and doors are manufactured from the specific steel alloy FeP02 which is then finished with a GZ200 hot zinc coating which protects the galvanised steel window frame from oxidisation.

These galvanised steel door profiles are then cold rolled to create the different Secco window and door profiles from our range. Cold rolling steel window frames creates a more stable steel window design all allows use to create slim steel profiles of 1.5mm thick for neater folds and edges.

A two part thermal break is used within all Secco steel windows and doors to create traditional steel windows with modern thermal performances. First a fibre glass reinforced structural break of extruded polyamide gives the thermal break enhanced stability then the thermal break is filled with high density polyurethane for high levels of thermal insulation to the steel windows and doors.

This method of thermal breaking creates a much stronger steel window or door frame to allow thinner profiles and larger opening sizes. Secco Galvanised Steel Frames are then powered coated at 1800C to any RAL colour required with a polished, semi-polished or a rougher sable finish available.

Various architectural design movements, such as the Bauhaus and Art Deco architecture, favour galvanised steel for  indows and doors and have cemented its use in luxury architecture.
