Standing seam Clip Fixings

Cleat screws used in standing seam metal roofing are highly specialized, self-drilling fasteners designed for the direct and efficient attachment of clips or cleats to metal substructures like steel or aluminium, eliminating the need for pre-drilling. These screws are manufactured from corrosion-resistant materials (such as BiMetal or stainless steel) to ensure durability and longevity, matching the roof system. They are characterized by a low-profile head - often flat or countersunk - which is essential for creating a smooth, frictionless surface over which the roofing panels can slide freely to accommodate thermal expansion and contraction. Professional versions frequently include features like specialized drive systems and locking mechanisms to prevent both over-driving during installation and subsequent loosening, thus providing a critical, high-strength, and precise hidden connection required for a reliable standing seam system.
