FRP Angle Profile
1. Product Overview
FRP Angle Bar (also known as fiberglass L-shaped profile) is a high-performance structural composite material manufactured by professional pultrusion technology. It adopts continuous glass fiber roving and fiberglass mat as reinforcement material, combined with polyester, vinyl ester or epoxy resin matrix, and is cured and molded at high temperature in one piece.
As an ideal replacement for carbon steel and stainless steel angle iron, FRP angle profile features corrosion resistance, insulation, light weight and high strength, which is widely used in harsh industrial environments where metal materials are not applicable.
2. Core Advantages
Excellent Anti-corrosion Performance The fiberglass structure will never rust or oxidize. It resists acid, alkali, salt spray, seawater and chemical gas erosion. No painting, anti-rust treatment or regular maintenance is required, greatly reducing later operation costs.
Light Weight & High Strength The density is only 1/4 of steel, which effectively reduces overall structural load. It features high specific strength, stable mechanical performance, convenient manual cutting and on-site installation without heavy hoisting equipment.
Non-conductive & Insulating FRP angle bar is an insulating and non-magnetic material with no eddy current and no electric conduction risk. It completely avoids short circuit and electric leakage hazards, fully meeting the safety requirements of power and explosion-proof projects.
UV Resistant & Long Service Life With anti-UV and weather-resistant formula, the product maintains stable size and performance under long-term outdoor, high temperature and humid conditions. The service life can reach 20–35 years.
Flame Retardant & Safe Customizable UL94 V-0 flame retardant grade, low smoke and non-toxic, suitable for power plants, chemical workshops and other fire-proof required scenarios.
Easy Processing & Customizable It can be freely cut, drilled, polished and bolted on site. Various specifications, colors and sizes are available for customization, including equal and unequal leg angles.
