California-based IronRidge Inc. has expanded its XR Rail family of solar mounting products.
Replacing the current XRS and XRL rails, the new line consists of three rail sizes: XR10, XR100 and XR1000. IronRidge says the new rails feature the family's curved profile shape intended to improve structural performance while reducing material cost.
IronRidge also introduced Slotted L-Feet and T-bolt Grounding Lugs peripherals. The Slotted L-Feet feature a serrated face to enable a high-friction connection to the rail. The T-bolt Grounding Lug mounts in the top slot of the rail in any direction and forms a bond by tightening the nut and washer.
The company has updated its Design Assistant Web-based design tool to support the new products. In addition, Design Assistant now uses the ASCE 7-10 methodology for its structural calculations.
