Highway-grade polyurethane composite bridge supports, manufactured in accordance with the transportation industry standard JT/T1034-2016 "Polyurethane Composite Cable Bridge Supports for Highways," are primarily used for protecting power and communication cables in the construction of expressways, ports, airports, and other infrastructure projects. The raw material, polyurethane (also known as聚氨酯), stands out in composite materials due to its good flexibility and rapid curing properties.

P.U. material bridge supports feature excellent corrosion resistance, moisture resistance, good adhesion, and high impact strength, making them suitable for use in special environments.
