Door frame options
Steel shield external doors come with a choice of frames to suit the widest possible structural doorway constructions.
As standard they come with the rapid fit “jacking screw” arrangement and adjustable sub frame channels that allow our doors to have the correct tolerance. This ensures simple installation, whilst expanding to fill the structural opening and leaving a neat joint ready for mastic to be applied.
As well as these standard design solutions our manufacturing and design facilities can deliver custom frames to suit any structural opening detail you need to install our doors into.

Standard frame
The standard Steelshield frame is designed for high durability, excellent corrosion resistance, and simple, secure installation across various structural openings.
It is highly versatile and can be securely fitted into a wide range of wall constructions, including:
Brickwork / concrete
Gas concrete
Prefabricated walls
Composite panel
Steel work
