Solar mounting systems require fasteners matched to the exposure, material and assembly method.
Choose the Finish
Hot-dip galvanizing is commonly considered for outdoor steelwork where a thicker zinc coating is specified. Zinc flake or zinc plating may suit applications with tighter thread or dimensional requirements. Confirm compatibility with the mounting system and the applicable standard.
Check the Specification
State the fastener grade, coating system, coating thickness, thread fit and inspection requirements in the drawing or purchase order. Coastal and high-humidity sites may require a different specification from inland projects.
Before Delivery
Review samples, certificates and any requested coating or dimensional inspection records before approving the batch.
