Structural Profiles - U-Shaped Square Tube Handrail Profile (Isophthalic)

Application Scenarios

The structural profile — U-shaped square tube handrail profile (isophthalic) — is commonly used for platform railings, stair handrails, walkway enclosures, bridge pedestrian passages and other locations requiring both load-bearing capacity and protection. The isophthalic resin system gives it good resistance in humid, mildly corrosive or outdoor environments, making it suitable for applications with long-term service stability requirements. Please confirm specific service conditions with us based on actual loads and media.

Selection Guidance

When selecting, first define the required cross-section dimensions, wall thickness and span of the handrail, then determine the matching fittings based on the installation method and connection joints. Different specifications differ in self-weight and rigidity; larger spans or higher protection requirements generally require larger cross-sections or additional support. To verify specifications against project conditions, please contact us for detailed specifications and a quotation.

Product Advantages

This profile is pultruded from glass fiber reinforcement and isophthalic resin, combining light weight, high strength and corrosion resistance; it is also non-conductive and non-magnetic, making it suitable for long-term use in a variety of environments. Its surface is dense and requires little routine maintenance, making it suitable as a substitute for some traditional metal handrail materials.
