High-Performance Bi-Metal & Timber Screws: Precision Engineering for the European Market

As a dedicated manufacturer focused on European quality standards, we introduce our latest innovation: the Bi-Metal Screw Series. Specifically engineered for the demanding requirements of photovoltaic installations, these fasteners combine the rapid drilling power of carbon steel with the permanent corrosion resistance of stainless steel.

Our newly developed bi-metal fasteners are designed for high-strength performance and speed. Featuring a precision-engineered smooth thread root and an ultra-sharp carbon steel tapping point, they deliver industry-leading drilling speeds into heavy-duty substrates. By fusing a hardened steel tip with a high-grade stainless steel body, we provide a solution that prevents structural fatigue and atmospheric corrosion—making them the ideal choice for long-term solar and roofing projects across Europe.
