FAQ
Q :
Can GRP Angles replace steel angles?
A :
Yes, in many applications, GRP Angles are a superior alternative to steel, especially in corrosive, electrically sensitive, and lightweight structures. However, for extremely high-load applications, steel may still be preferred.
Q :
Are GRP Angles fire-resistant?
A :
Yes, depending on the resin type used: 🔥 Standard Polyester Resin – Basic fire resistance. 🔥 Vinyl Ester Resin – Better fire resistance & chemical resistance. 🔥 Phenolic Resin – High fire resistance, low smoke emissions, ideal for tunnels and public transport. Always check fire rating requirements before selecting a material.
Q :
Can GRP Angles be cut and drilled on-site?
A :
Yes! GRP Angles can be easily cut, drilled, and machined using standard tools such as: Circular saws with diamond/tungsten carbide blades. Drills with HSS (High-Speed Steel) bits. Angle grinders for smooth finishing. 💡 Tip: Use dust extraction or wear a mask when cutting to avoid inhaling fine dust.
