Supporting heavy cooling towers, chemical scrubbers, and industrial pumps in corrosive environments requires structural members that match the load-bearing capacity of steel without its vulnerability to rust.
In this structural design article by Rawji Exports (kumar), we discuss section properties, modulus of elasticity, and bolt connection detailing for pultruded GRP structural profiles.
1. Pultruded Profile Strength Characteristics
- High Strength-to-Weight Ratio: GRP profiles weigh 75% less than structural steel while delivering comparable longitudinal tensile and compressive strength (> 200 MPa).
- Dielectric Insulation: Zero grounding requirements when installed near high-voltage transformers and switchyards.
- Standard Structural Shapes: I-Beams, H-Columns, C-Channels, Equal Angles, Square Hollow Sections, and Solid Rods.
