Frequently Asked Questions

Q: How do Fiberglass I beams compare to steel in terms of strength?

While steel has higher absolute strength, FRP I beams offer a superior strength-to-weight ratio, providing sufficient structural integrity for most industrial applications while being significantly lighter.

Q: Which resin should I choose for high chemical exposure?

For environments with high chemical aggression, Vinyl Ester resin is recommended due to its superior resistance to corrosion compared to standard Polyester resin.

Q: Are FRP I beams UV resistant?

Yes, our fiberglass I beams can be manufactured with integrated UV inhibitors to prevent degradation and discoloration from prolonged sunlight exposure.

Q: Can Fiberglass I beams be used in electrical installations?

Absolutely. Their non-conductive and non-magnetic properties make them the safest choice for substations and transformer platforms.

Q: What is the typical lifespan of an FRP structural beam?

Depending on the environment and load conditions, our fiberglass I beams typically offer a service life exceeding 25 to 50 years.

Q: Do I need special equipment to install FRP I beams?

No, they can be cut and drilled using standard power tools. Their lightweight nature often eliminates the need for heavy cranes during installation.
