What is the material used for fence brackets?

Trex fence brackets are made of high strength material called glass-filled nylon. By adding powdered glass to the nylon resin or extruding the plastic with glass fibers, the raw material in glass-filled nylon takes on several beneficial properties:

• Material stiffness is up to 80 percent greater than common plastics
• Tensile strength is up to 70 percent greater than common plastics
• The thermal expansion rate that is roughly half of unfilled nylon, providing increased stability when exposed to temperature changes
• The hardness is 50 percent greater than common plastics

Trex Fencing bracket material and the bracket design were used in the development of the component specifically because they offer far superior performance benefits over a metal or standard plastic component. Combined with the 5/8" wall thickness of a Trex post, Trex fence brackets add to the overall strength of the fence system, handling high wind loads and common incidental stress from low impact events (such as balls kicked against the fence or lawnmower bumps) that happen across the life of a fence.
