FRP Yellow I-Beam
FRP I Beam is a pultruded fiberglass reinforced plastic wide flange section designed for load bearing applications where steel would corrode. The I shape places material where bending stress is highest, in the top and bottom flanges, while the web carries shear, giving a high strength to weight ratio. At about one quarter the weight of steel, the beams are easy to transport, lift and install on site, yet they resist moisture, acids, alkalis and salt spray without rusting or repainting. The material is electrically non conductive and will not degrade in chemical, coastal or wastewater environments. Typical uses include industrial platform beams, walkway supports, bridge access structures, cooling tower frames, equipment supports and electrical insulation structures. Custom depths, flange widths and colors are available.

FRP I Beam is a pultruded fiberglass wide flange section made for structural spans where load carrying matters. The I shape is not decorative. It puts material where bending stress is highest and removes material where it does little, so the section carries more load per kilogram of material than a solid or rectangular bar.
Why the I Section Carries More Load
Top and bottom flanges resist bending forces
Web carries shear between the flanges
Material concentrated at the farthest points from the neutral axis
High stiffness to weight ratio compared with solid bars
Consistent pultruded profile along the full length
A Beam That Outlasts Steel in Harsh Environments
Resists acids, alkalis, salt spray and wastewater exposure
No rusting, no pitting, no repainting cycle
About one quarter the weight of steel, lifts by hand on site
Electrically non-conductive and non-magnetic
Cuts, drills and bolts with standard steel fabrication tooling
Service life of decades with minimal maintenance
Where These Beams Are Put to Work
Main beams for industrial operating platforms and walkways
Bridge inspection and maintenance access structures
Cooling tower support frames and fills
Chemical plant pipe racks and tank supports
Offshore and coastal secondary access structures
Electrical substation and isolation structures
Sound barrier posts and highway sign supports
