Shanghai Malaxy Industry Co., Ltd. 

Secure Your Solar Investment with Anti-Corrosion Bi-Metal Screws

Our 6x25 Bi-Metal Screws are engineered specifically for the demanding environments of photovoltaic (PV) mounting systems. They combine a stainless steel head for corrosion resistance with a high-strength carbon steel thread, creating the perfect fastening solution where dissimilar metals meet. The proprietary RUSPERT coating provides an extra barrier, ensuring unparalleled protection against galvanic corrosion caused by weather and environmental exposure.

Key Features & Benefits:

Eliminates Galvanic Corrosion: The bi-metal construction and RUSPERT coating effectively prevent rust at critical connection points between aluminum rails and steel structures, extending system lifespan.

Engineered for Vibration Resistance: Withstands dynamic loads and constant thermal cycling, keeping your solar array secure over decades.

Optimized for Solar Applications: The precise 6x25mm size is ideal for securing mounting clips, L-feet, and other hardware to aluminum rails and steel purlins.

Maximum Durability: Offers the cost-effectiveness of carbon steel and the corrosion resistance of stainless steel in one superior product.
