Product Overview
FRP square tube, also known as fiberglass square tube, GRP square tube, or fiberglass structural square tube, is manufactured from fiberglass reinforced plastic for stable performance in demanding environments. It is widely used in handrail systems, frames, support structures, equipment assemblies, and custom industrial fabrication.
Main Applications
FRP square tube is suitable for projects that require a durable square profile with corrosion resistance and good dimensional consistency. Typical applications include:
- structural frames and support members
- handrail and guardrail systems
- equipment stands and brackets
- cable support assemblies
- marine and coastal installations
- chemical processing facilities
- wastewater treatment plants
- outdoor and humid environments
- custom fabrication for industrial components
Material and Construction
FRP square tube is produced from fiberglass reinforcement combined with a resin system selected for the operating environment. The square hollow profile can be manufactured to suit project-specific requirements for strength, appearance, and installation.
Common characteristics include:
- square tubular profile
- non-metallic construction
- corrosion-resistant surface
- lightweight and easy to handle
- customizable resin system
- customizable color and finish
- suitable for cutting, drilling, bonding, and assembly
The exact outer size, wall thickness, length, resin type, and finish should be selected according to structural requirements, installation method, and environmental exposure.
Key Advantages
Corrosion resistance
Suitable for wet, salty, acidic, alkaline, and chemically aggressive environments.
Structural versatility
Can be used in frames, supports, handrails, and custom assemblies.
Lightweight handling
Easier to transport and install than many metal alternatives.
Electrical insulation
Useful in applications where a non-conductive structural member is preferred.
Low maintenance
FRP does not rust, which helps reduce repainting and replacement costs.
Easy fabrication
Can be cut, drilled, and assembled into project-specific systems.
