Cladding & roofing screws are specialized fasteners used to securely fix metal roofing sheets, wall cladding panels, and related materials to structural supports (like steel or timber). They’re designed for outdoor use and to prevent water leakage and corrosion.
Key Features
- Self-drilling / self-tapping: Many have a drill-point tip so they can penetrate metal or wood without pre-drilling.
- Sealing washer: Most have an EPDM rubber washer under the head for waterproof sealing.
- Corrosion resistance: Coatings like galvanized, zinc/aluminium, or Class 3 certified finishes protect against rust in exposed environments.
- Head types: Usually hex head (easy for power tools) or bi-hex/colored head options for aesthetic exterior finishes.
