UV Resistant Solar Panel Mounting Screws with High Torque Performance for Outdoor Use

1. Q235 Carbon Structural Steel: It has certain strength and toughness and relatively low cost. It is widely used in the production of screw piles for general construction and civil engineering projects. After hot-dip galvanizing treatment, its corrosion resistance is significantly improved, and it can effectively prevent rusting in ordinary environments and extend the service life of the piles.

2. Q345 Low-Alloy High-Strength Structural Steel: Compared with Q235 steel, Q345 steel has higher strength and better comprehensive mechanical properties. It is suitable for engineering projects with higher requirements for load-bearing capacity, such as industrial plants, large billboards, and wind turbine foundations. It can also be subjected to hot-dip galvanizing or other anti-corrosion treatments to enhance its corrosion resistance in harsh environments.
