The Engineered Sealing Fastener for Metal Roof Systems.
A Roofing Bolt is a specialized fastener designed to securely attach metal roofing panels while maintaining a watertight seal. It typically consists of a threaded bolt, a matching nut, and a critical sealing washer, working together to prevent water infiltration at penetration points—a common failure point in metal roofs.
Integrated Washer/Cap Design: A large, durable plastic cap is permanently fused with a waterproof EPDM or neoprene washer, forming a single, reliable unit.
Wide Sealing Surface: The broad diameter of the cap and washer distributes pressure evenly and creates a large sealing area to block water entry.
Watertight Compression Seal: When driven, the washer compresses tightly against the material surface, forming a permanent, waterproof barrier around the nail shank.
Corrosion-Resistant Shank: The nail is typically made of galvanized steel or stainless steel to prevent rust from compromising the seal.
UV-Stabilized Plastic Cap: The umbrella head is resistant to weathering and solar degradation, maintaining its integrity and color over time.
200-300mm
Weight Varies By Profile
Zinc-Plated Steel: A cost-effective option with good corrosion resistance for standard applications.
Hot-Dip Galvanized: Offers a thicker zinc coating for enhanced protection in more aggressive environments.
Stainless Steel 304/316: The premium choice for maximum corrosion resistance, essential in coastal or industrial areas.
Aluminum: Lightweight and rust-proof, ideal for aluminum roofing panels to prevent galvanic corrosion.
Standing Seam Roof Fastening: Used with fixed or sliding cleats to secure the roof panel to the structural substrate.
Corrugated Metal Roofing: Directly fastens corrugated sheets to purlins through the crest of the corrugation.
Metal Wall Cladding: Secures siding and facade panels while maintaining a weatherproof barrier.
Roofing Accessory Attachment: Installs snow guards, ventilation units, and solar panel mounts without compromising the roof’s waterproof integrity.
