Self-drilling Design: The drill tip quickly penetrates the metal panel and base steel, eliminating the need for pre-drilling and significantly improving installation efficiency.
Double-thread Construction: The upper thread securely engages the panel metal layer, while the lower thread secures the panel metal layer.
High Strength: Suitable for applications requiring high wind loads, tension, and shear resistance.
Corrosion Resistance: Available in stainless steel or high-grade anti-corrosion coatings, suitable for outdoor and high-rise applications.
Customizable: Custom lengths, head shapes, and colors (RAL coating) can be customized to meet project requirements.
Length range: 50 mm – 300 mm
Screw head: 8 mm hexagonal nut head for easy electrical installation
Surface finish: Available in zinc plating, chrome plating, anodized, or stainless steel (A2/A4) to meet the corrosion resistance requirements of different environments
Specially designed for sandwich panel installation, this galvanized self-drilling screw with EPDM washer delivers strength, precision, and long-term reliability in roofing and cladding projects. Constructed from hardened steel and finished with a high-quality galvanization, the screw offers excellent resistance against rust and corrosion, ensuring dependable performance in outdoor environments.
The integrated EPDM washer provides an effective watertight seal, preventing leaks and protecting structures against moisture damage. Its elasticity allows it to maintain consistent sealing under pressure, even in fluctuating temperatures or harsh weather conditions. This feature makes it a trusted choice for roofing professionals who require both strength and waterproof security.
Equipped with a sharp self-drilling tip, the screw eliminates the need for pre-drilling, significantly reducing installation time while ensuring clean, accurate fastening. The deep, precision-formed threads are designed to grip firmly into both metal and wood substrates, keeping sandwich panels securely in place and minimizing the risk of loosening due to vibration or wind uplift.
Its robust construction, combined with efficient installation and weatherproof sealing, makes this screw ideal for industrial, commercial, and residential roofing applications where long-term performance is essential.
