Engineering Overview & Technical Application

Modern Pre-Engineered Buildings (PEB) and industrial warehouses rely on trapezoidal box-rib roof profiles for superior water drainage and load-bearing strength across purlins. Rawji Exports manufactures precision-moulded trapezoidal FRP roofing and side-wall cladding sheets that match standard PEB metal profiles (e.g., 1000/30, 1020/28, 1072/35).

Common Queries

Frequently Asked Questions

Detailed technical and commercial answers from our composite product engineering team.

Our trapezoidal profiles feature a deep anti-capillary siphon groove along the overlap crest that breaks surface tension and prevents wind-driven rain from penetrating the joint.

Yes. They are widely used as side-wall cladding in industrial sheds, cooling towers, and chemical storage yards where vertical durability and corrosion resistance are essential.

We recommend self-drilling carbon steel / SS screws with 19mm diameter EPDM-bonded galvanized steel washers for leak-proof fastening.
