Leading Manufacturer Of Steel Roof Screws
Steel Roof Screws, also known as Metal Roofing Screws / Self-Drilling Roof Screws, are roof screws designed specifically for installing color steel tiles, galvanized sheets, and metal roofs.Core functions: wind pressure resistance, water leakage resistance, corrosion resistance, and ensure the roof structure has a lifespan of 20+ years.
Common Roofing Screws For Polycarbonate
Stainless Steel Metal Roofing Screws
Stainless steel roofing screws: Made of stainless steel, they are highly resistant to corrosion and are suitable for metal roofs in high humidity or coastal areas. Stainless steel roofing screws with washers can seal and prevent rainwater leakage.
Metal Roof Sheet Screws
Metal Roof Sheet Screws: Universal design, suitable for a variety of metal roof panels, providing stable bite
Metal Roofing Self Tapping Screws
self tapping roofing screws: With self-tapping threads, screw directly into the metal plate without pre-drilling.
Self Drilling Screws For Metal Roofing
roofing self drilling screws: The tip integrates the drill bit, completes drilling + locking in one step, suitable for thick metal substrates.
Metal Roof Replacement Screws
Metal Roof Replacement Screws: Designed for renovation, compatible with old holes, and the anti-rust coating extends the life of the roof.
Black Metal Roofing Screws
black roofing screws: The black coating blends with the roof color, taking into account both aesthetics and anti-rust functions.
Oversized Metal Roof Screws
Oversized Metal Roof Screws: Thickened threads + large diameter head, enhanced wind pull resistance, used in high-load areas.
Screws For Corrugated Metal Roofing
Screws For Corrugated Metal Roofing: Curved gaskets fit the grooves of corrugated panels to prevent water leakage and disperse pressure
Green Metal Roofing Screws
Green Metal Roofing Screws: The green coating is consistent with the roof tone, and the anti-rust process ensures durability, taking into account both concealment and corrosion resistance.

Advantages of Polycarbonate Roofing Screws
1. Anti-rust and anti-corrosion technology
✅ Triple protection system
Base material: stainless steel (high hardness and shear resistance)
Coating: galvanized, Dacromet, salt spray resistance 800 hours)
Seal: EPDM rubber gasket (aging resistance, -40°C~120°C elasticity retention)
Compared with ordinary galvanized screws: life is increased by 3 times, maintenance-free for 10 years+ in coastal areas
2. Revolution in self-tapping efficiency
✅ Self-drilling tip
Design: double spiral chip groove, penetrating 1.5mm steel plate in only 4 seconds
Save 50% time: no pre-drilling is required, directly drive into the steel purlin
3. Washer sealing and wind resistance
✅ Waterproof system
Pressure sensing gasket: automatic water stop with compression rate of 30%, IP68 certification
Anti-wind design: hexagonal flange head + EPDM gasket, tensile force ≥800N (EN 1993 standard)
Common Size Recommendations Of Best Metal Roof Screws
FAQ
Q1: What screws are used on metal roofs?
A1: Spacing (cm) = (board thickness mm × 3) + 10. Example: 6mm board → 28cm spacing
Q2: What size screws for sheet metal roofing?
A2: If the hole diameter is less than 5.5mm, the original hole can be used directly; if it is enlarged, it needs to be filled with a special EPDM hole plug.
Q3:What screws are used for sheet metal?
A3:After correct installation, the gasket thickness is reduced by 1/3 and there are no wrinkles on the edge.
Q4:What screws to use for corrugated sheeting?
A4:Yes, but an additional anti-slip gasket (code: PS-AntiSlip) is required.
