Hollaender has launched two new Speed-Rail fittings designed specifically for installation of solar racking systems in areas that experience extreme wind. The fittings, which include a tee and elbow for use with two-inch pipe, can be used with aluminum, galvanized steel, stainless steel or black iron pipe to build solar panel racking systems.
The ability to withstand uplift caused by wind loads is critical in solar pipe racks, the company says. While installers in most regions of the U.S. must design for 90 mph winds, certain coastal areas, such as South Florida and the Gulf Coast, must design for 135 mph and higher wind speeds.
On a Speed-Rail fitting, the component that produces pipe holding power is a single integrated proprietary internal-external reverse-knurl cup-point set screw that securely attaches the fittings to the pipe and provides resistance to loosening and pullout. The new fittings are designed with two set screws, producing a substantial increase in pullout resistance, Hollaender adds.
