Highway-use Polyurethane Composite Bridge Beams, manufactured in accordance with the transportation industry standard JT/T1034-2016 "Polyurethane Composite Cable Bridge Beams for Highways", are primarily used for the protection of power and communication cables in the construction of expressways, ports, airports, and other engineering projects. The raw material, polyurethane (short for聚氨酯), stands out in composite materials due to its excellent flexibility and quick curing properties.

Polyurethane material bridge structures feature anti-corrosion, moisture resistance, good adhesion, and high impact strength, suitable for use in special environments.
