Product Overview

FRP Support Beam is a type of Fiberglass Pultruded Profile material. FRP support beams are advanced composite profiles manufactured through pultrusion process using high-performance fibers and resin matrices. Compared to traditional steel, they offer lightweight, high strength, zero corrosion, electrical/magnetic insulation, and maintenance-free advantages, specifically designed to address durability issues of steel structures in corrosive, high-humidity, and electromagnetically sensitive environments.

Typical Applications

1. Construction

Curtain wall mullions, skylight supports, seismic reinforcement

2. Bridge Engineering

Pedestrian bridge beams, railings, expansion joint connectors

3. Industrial Facilities

Chemical plant platforms, electroplating tank supports, offshore wind power structures

4. Special Scenarios

Insulating supports for maglev tracks, non-metallic components for nuclear plants

Feature

1. Strong corrosion-resistance

After soaking in 3% HCl solution for 24 hours, the hardness retention rate of the pultrusion profile is 95%. After soaking in 3% NaCl solution for 24 hours, its hardness retention rate was 89%.

2. Low thermal insulation coefficient

The heat transfer coefficient of the pultrusion profile is close to rigid PVC, and the thermal isolation coefficient of the double-glass insulation window made by the single frame is only 2.69W/(m²·K).

3. Adapt to environmental requirements

The selected pultrusion profile processing technology has the characteristics of low noise, low power consumption and low pollution.

4. High heat distortion temperature

The pultruded profile’s thermal deformation temperature is 186℃. It will not soften at high temperatures or be brittle at -60℃, ensuring regular use under various ambient temperatures.

5. Low deformation rate

After 1000 hours of artificial accelerated aging, the length change of FRP pultruded profiles is +0.03%, and the width change rate is -0.07%. So, the shape and size of the product made of this pultrusion profile can be maintained for a long time.

6. High strength

The pultruded profile’s tensile strength is 150-300MPa, its bending strength is 200-300MPa, and its bending strength preservation rate after 1000h of artificial accelerated aging can reach 78%.
