  • Description

The FRP rectangular tube is a lightweight structural material that can be used in various fields such as construction, industrial, and electrical. As it is made from materials like fiberglass reinforced plastic (FRP), using it as a rectangular tube provides corrosion resistance, structural support, and effective protection. It also offers fire resistance and electrical insulation properties.

Applications: Construction, industrial, transportation, electrical, aquaculture, agriculture, etc.

Product Features: The use of FRP material in the rectangular tube ensures its lightweight benefits, corrosion resistance, and effective fire retardant properties.
