Cold-rolled steel sections from pre-galvanized steel (Zn coated or Al/Zn coated 55%) coil to produce a cost-effective building material that allows fast fixing to frame members and labour cost reductions.
High demand by both engineers and developers as well owners due to being an economical alternative to timber battens. The consistent quality and dimensional accuracy as well as the resistance to termite attack have proven the product’s worthiness.

Laying and Lapping of Steel Roof Battens
To minimize cutting, lay all battens in one direction, starting from one end.
The overlap must be supported over a truss or rafter, as shown in the figure above.
Minimum overlap-ping distance is 100mm.
Handling and Storage
All metal roof battens should be kept dry and stored under cover and above the ground.
To maximize the steel batten life cycle, steel sections which are exposed to water must be separated
and air dried as soon as possible to remove any moisture retention.
