BDN Polycarbonate roofing screws: for Fixing Corrugated Polycarbonate to Metal and Timber. Creates an expansion hole in a one-shot process, fixing skylights easily onto steel substrates.

POLY-FAST™ roofing fasteners feature a Thermal Expansion Hole Cutter that creates a much-required thermal expansion hole on plastic profiled roofing panels. The panels are then securely fastened onto the purlin support underneath in one–go. A nominal 11mm diameter hole is created by the Thermal Expansion Hole Cutter during the process.

2022年8月9日 · Dealing with screws for polycarbonate roofing poses a significant challenge due to the material’s relatively high coefficient of thermal expansion. Current industry practice is to ream a I0mm hole in a non-metallic roofing profile to install a #12, 4.5mm diameter screw.

The 2 in. wood fastener is designed for use with EZ Glaze polycarbonate panels. It secures the plastic roofing panels to wood frames. The fasteners resist corrosion and rust for long-term durability.

Polycarbonate Multiwall fasteners are a quick and easy way to secure panels to a variety of framing materials. They can be used with wood and metal structures and come with a pre-fitted washer creating a watertight seal in any climate.

Poly-Fast™ & POLYXPAND™ screws for polycarbonate roofing are designed to create a much-required thermal expansion hole on plastic roofing materials as corrugated roof screws and then securely fastened onto the purlin underneath in one-go.

What type of screw should you use when installing polycarbonate panels? It is important to choose the correct fastener for your specific application. We recommend using a minimum of #10 course screw for soft woods (fir, pine, cedar or spruce) and #10 self-drilling screw for metal, such as aluminum or steel.

2022年5月13日 · Polycarbonate sheets, with its high coefficient of thermal expansion, common among most thermoplastics, require special care when installing. One of the most overlooked points is the choice of screws and fixings, which is imperative to the overall performance and lifespan of the sheet, no matter where they are affixed to.

Polycarbonate screws resist breaking in high-impact applications better than other plastic screws. All are chemical and oil resistant, nonconductive, and lightweight. They’re angled under the head to sit flush within countersunk holes.
