Materials and structures
Metal roof screws are usually made of materials such as stainless steel or galvanized steel. Stainless steel has excellent corrosion resistance and durability, while galvanized steel provides a protective coating to prevent rust. In terms of structure, they usually have a wide head to increase the contact area with the roof panel, and are usually equipped with a waterproof gasket to prevent water leakage.

Application areas
The application areas mainly include various buildings with metal roofs, such as industrial plants, warehouses, and some residential buildings.

Working principle
The working principle is that by screwing into the roof structure, they provide a stable connection to fix the metal roof panel in place. The wide head and waterproof gasket help to disperse the pressure and prevent water from penetrating, thereby ensuring the integrity and stability of the roof.
