Composite Panel to Light Section

Composite panel to light section screws are specialist long-reach self-drilling fixings developed specifically for securing insulated composite sandwich panels to light gauge purlins, rails and secondary steel framing. Available in lengths from 65mm to 300mm with a #2 drill point, they are engineered to penetrate the full panel depth and drill cleanly into steel thicknesses up to 3.5mm in a single operation. These screws feature a high-thread profile with an aggressive, deep thread design that delivers superior grip, excellent pull-out resistance and strong clamping force through the insulation core and thin metal skins. The combination of the sharp self-drilling point and high thread ensures fast, accurate installation while maintaining precise panel alignment and long-term structural integrity. Supplied with bonded EPDM washers as standard, they provide reliable weather sealing and load distribution at every fixing point, making them essential for high-performance composite panel roofing and cladding systems.
