Today, our production team completed another batch of self drilling roofing screws ready for export.
These fasteners are mainly designed for steel structure and metal roofing applications, especially widely used in PPGI sheet installation, warehouse construction, and solar mounting systems.
Before packing, each batch went through basic quality inspection, including thread check, drilling performance test, and coating appearance verification. We focus on keeping every screw consistent and reliable for on-site installation.
This shipment will be delivered to our overseas customer for an ongoing steel structure project. Fast delivery and stable quality remain our daily priority.
At Dongchao, we believe small fasteners play a big role in construction safety and efficiency.
