Sometimes surrounding structures are not strong enough to take a roller shutter door. In these cases, custom made steelwork is manufactured to be used for openings where supporting structure is not of adequate strength to take roller shutter.
Slotting can cover a whole curtain or a section of curtain, whichever your preference.
As with the slotted slats, perforated slats can be used on a whole curtain or just a section of the curtain. View our perfslat product here.
Mullions & Dividers
In many cases, it is preferable to be able to open a large area on the side of a building or warehouse, in which case, mullions are used. Mullions are steel structures with side guides fitted each side to allow the shutters to close into them.
Sliding centre mullions
Are designed to slide out of the way when the doors are open.
Are designed to be lifted up against the ceiling and secured horizontally via a manual or electronic winch.
