1. What is a GRP Wide Flange Beam?

A GRP (Glass Reinforced Plastic) Wide Flange Beam, also known as an FRP (Fiberglass Reinforced Plastic) Wide Flange Beam, is a structural profile designed to provide high strength, lightweight, and superior corrosion resistance. Unlike traditional steel beams, GRP wide flange beams are non-corrosive, non-conductive, and require minimal maintenance, making them ideal for applications in marine, chemical, industrial, and outdoor environments.

📌 คุณสมบัติที่สำคัญ:

✅ Corrosion-resistant – Ideal for chemical plants, marine environments, and industrial applications.

✅ Lightweight but strong – 75% lighter than steel, making it easier to transport and install.

✅ Non-conductive – Electrically and thermally insulating for safe use in electrical environments.

✅ Low maintenance – No rusting, repainting, or chemical treatments needed.

✅ Fire retardant options available – Complies with international fire safety standards.
