3’’ (76mm) curved steel lath

The main body of the door, more commonly called the ‘curtain,’ can be constructed from steel or aluminium in a number of different styles.
The most common being the traditional 3’’ (76mm) curved steel lath.

Used on a vast range of applications, the laths are constructed from galvanised interlocking curved sections, of suitable gauge (material thickness) to suit the size of a particular shutter.

Each alternate lath is fitted with a malleable steel endlock to prevent lateral movement.
The base of the curtain is fitted with an inverted galvanised ‘T’ section ‘bottom rail’.

3’’ (76mm) curved steel lath can be provided with either singular or a series of 225 x 30mm punched slots to provide ventilation or vision.
Perspex backing strips can also be provided.

The 3’’ (76mm) curved steel lath can also be supplied as ‘perforated’, thousands of 3mm perforations provide near perfect visibility through the curtain, particularly at night to back lit windows displays.
The perforations allow approx. 19% air flow through the curtain making them ideal for applications where ventilation as well as security has to be taken into consideration, such as under croft car parks.
