Standard 15mm. Versatile and wheelchair-friendly, construction may be of galvanised or stainless steel.
Reverse Head. Excellent weatherproofing and sound reduction properties. Regularly used to manage a change of floor levels, and manufactured in a height to suit the application.
No threshold, flat bottom. Suitable for internal applications that require a minimal floor gap, such as seclusion rooms.
Automatic drop seal. An external doorset with no threshold often needs a dropseal to prevent water ingress.
Type RL. A special threshold for Type 3 frames, normally used for portable buildings. As the bottom edge of this frame is visible below the door, construction is normally of stainless steel
The threshold is designed as an integral part of the doorset, giving additional strength to the frame; aiding weatherproofing and sound reduction, and providing a stable surface for lower locking points.
For general purpose industrial buildings, construction is normally of galvanised steel. For offices, shops and public buildings, aluminium or stainless steel is used for the aesthetic qualities. For food preparation areas or wet situations, stainless steel has the necessary hygienic and corrosion resistance properties.
For very heavy use, we can fit additional internal reinforcing. For severe duty use, such as forklift traffic, solid stainless steel gives the ultimate in strength.
Where no threshold is required for a level access, the doorset will be delivered with a temporary threshold which is removed after installation.
We recommend that external doorsets with no threshold should be fitted with an automatic drop seal, to minimise water ingress, draughts and noise. Dropseals may be surface mounted or concealed within the door bottom.Request AutoCAD dwg
