FAQ
Q :
How strong is a GRP Wide Flange Beam compared to steel?
UN :
While GRP is not as strong as steel in absolute terms, its strength-to-weight ratio is comparable or even superior. GRP wide flange beams can support significant loads without adding excessive weight, making them ideal for lightweight structural applications.
Q :
Are GRP Wide Flange Beams fire-resistant?
UN :
🔹 Standard GRP: Moderate fire resistance. 🔹 Fire-retardant GRP (FR-GRP): Available in special formulations meeting BS 476, ASTM E84, and EN 13501 fire resistance standards. 📌 If fire resistance is a priority, use phenolic resin-based GRP for the best fire performance.
Q :
Can GRP Wide Flange Beams replace steel beams?
UN :
Yes, in many cases. GRP wide flange beams are commonly used in: ✔ Marine and offshore structures ✔ Chemical plants and corrosive environments ✔ Electrical substations (non-conductive, safe) ✔ Construction frameworks where lightweight materials are preferred 📌 However, for very high-load applications, steel may still be necessary.
Q :
How do you install a GRP Wide Flange Beam?
UN :
🛠 Cutting: Use a diamond or carbide-tipped saw. 🔩 Fastening: Use stainless steel bolts or GRP-specific adhesives. 🛠 Bonding: Structural adhesives like epoxy can provide strong joints. 📌 Tip: Wear protective gear when cutting GRP to avoid inhaling fiberglass dust.
Q :
How long do GRP Wide Flange Beams last?
UN :
⏳ Over 20 years, even in harsh conditions, due to: ✅ Corrosion resistance ✅ UV and weather protection ✅ Low maintenance requirements
Q :
Are GRP Wide Flange Beams customizable?
UN :
Yes! Customization options include: ✔ Size & thickness – Tailored dimensions available ✔ Resin type – Polyester, vinyl ester, epoxy, phenolic ✔ Fire resistance – Fire-retardant versions available ✔ Color – Gray, yellow, green, red, black, or custom ✔ Length – Standard or cut-to-size
