Construction & Roofing Screws

What construction and roofing demand

Outdoor fasteners live or die by corrosion resistance. Roofing and cladding screws also need to pierce and tap metal or bite into timber fast, often with a sealing washer. Specifying the right finish is critical for service life.

Recommended products

• Self tapping & self-drilling screws — for sheet, purlin and cladding fixing.
• Construction / chipboard screws — bugle head, deep thread for timber and drywall.
• Custom screws — special lengths, washers and heads to your drawing.

Finishes for outdoor and coastal use

For exposed and marine environments, choose Dacromet, Geo-met or Ruspert — zinc-flake and multi-layer coatings reaching 500–1000+ hours salt spray without the hydrogen-embrittlement risk of plating. Compare options in our finishes guide.
