Built for High-Performance Jobs
- High-performance roofing and cladding don't forgive weak fasteners. Our advantage isn't a slogan-it's the factory system behind each box.
- Capacity: dedicated self-drilling screw lines plus in-house EPDM washer bonding. Screw, coating, and washer are controlled under one roof, so output and lead times stay stable for repeat and seasonal orders.
- Price: integrated production removes outsourced-washer and extra handling costs. You get a competitive wholesale price without trading down on coating or seal quality.
- Service: one contact checks panel thickness, purlin gauge, washer spec, and target corrosion life before quoting. Free samples before mass production; data confirmed against your samples first.
- Wholesaler profit: a differentiated product that reduces leaks, stripped heads, and callbacks-fewer returns, better shelf reputation, and repeat orders. Packing and mixed sizes can be planned around your market.
- Lower long-term cost: longer service life and fewer leak repairs outweigh a slightly higher piece price. Your customer pays less over the life of the roof.
