Strut Channel Covers

Turn strut channel into four-sided raceway with covers that snap into the opening. They protect wire, cable, and other contents from damage, dust, and debris while adding a finished look.

Zinc-Plated Steel—Strong and durable with a zinc plating that protects from occasional exposure to moisture.

Powder-Coated Steel—Match the color of your steel strut channel.

304 Stainless Steel—The choice for wet and outdoor environments, these resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.

Aluminum—One-third the weight of steel for easier handling. These are an alternative to stainless steel for rust resistance but aren't as strong.

Roof Panels

Steel

These roof panels are impact, heat, weather, UV, and corrosion resistant. Corrugated for added strength and rigidity, they’re more durable than flat panels and require less maintenance. Use them to roof and side commercial, agricultural, and residential buildings. All panels have been tested by ASTM for flame resistance. Cut these down to size using a circular saw.

Use panel connectors (sold separately) to join panels together side by side. You’ll need one connector for every foot of panel.

Add finishing strips (sold separately) to keep dirt and dust out of the top and bottom ends of panels.

Clear—Clear polycarbonate panels make for durable windows and skylights.

Semi-Clear—Semi-clear polycarbonate panels block 55% of light, which helps maintain temperature and still let some light through.

Painted Steel—Painted Steel panels are our most impact resistant and durable roof panels. Completely opaque, they reflect light to insulate and save energy. They overlap with adjacent panels, so you don’t need connectors to join them side by side with other steel panels.

Polycarbonate—Polycarbonate panels are lightweight and easier to install than steel panels, but they’re not as energy efficient. They come in clear and semi-clear styles, so they’re good when you need to let some light in.

Connectors—Use panel connectors (sold separately) to join panels together side by side. You’ll need one connector for every foot of panel.
