FRP Angle steel

Basic information

Definition: The cross-section is in the shape of a right-angle "L", composed of glass fiber and resin (such as polyester resin, epoxy resin). Its function is similar to that of traditional metal Angle steel, but it has the unique advantages of fiberglass reinforced plastic materials.

Production process: The mainstream method is pultrusion molding, and the process is as follows:

The glass fiber roving is evenly impregnated with resin through the traction device.

The impregnated fiber bundles enter the "L" -shaped cross-section mold and are heated and solidified to form.

Continuous pultrusion and cutting into the required length eventually form FRP Angle steel of uniform specifications.

Core performance characteristics

Lightweight and high strength: Its density is only 1/4 to 1/5 that of steel, making it light in weight and easy to handle and install. The tensile strength can reach 150-300 mpa, and the bending strength is approximately 200-300 mpa. It can be used to replace steel for supporting medium and small-sized structures.

Excellent corrosion resistance: It does not rust or corrode, can withstand harsh environments such as acids, alkalis, salts, and humidity, and does not require anti-corrosion painting. It is suitable for scenarios such as chemical engineering, Marine, and sewage treatment.

Good insulation performance: It is an insulator, neither conducting electricity nor heat, and can be used in fields with insulation requirements such as power equipment brackets and telecommunication signal towers.

Strong weather resistance and stability: After adding ultraviolet absorbers, it can be used outdoors for a long time without aging or deformation. The coefficient of thermal expansion is close to that of concrete, making it more stable in combination with building structures.

Flexible designability: It can be customized with different cross-sectional sizes (such as side lengths of 25mm-100mm), thicknesses and lengths, and colors can also be mixed to meet the appearance and functional requirements of different scenarios.

Main application fields

In the industrial field: It can be used as a support for workshop equipment, platform beams, and pipeline supports, replacing metal Angle steel to reduce corrosion losses. 
In the field of construction: It is used for purlins, partition wall frames, and curtain wall supports in lightweight buildings to reduce the self-weight of the buildings. 
In the chemical industry: It is used as anti-corrosion supports and the frames of drainage ditch covers in chemical plants and sewage treatment plants. 
In the power field: We produce brackets for power inspection platforms and frames for substation equipment, taking advantage of their insulation properties to ensure safety. 
In the agricultural field: Build the framework of greenhouses and brackets for irrigation pipes to resist corrosion in humid environments.

Fiberglass pultruded angle bar are strong, lightweight structural profiles made from reinforced fiberglass composites. They offer excellent corrosion resistance, high tensile strength, and long-term durability, making them ideal for construction, marine, electrical, and industrial applications. Designed for stability and insulation, they perform reliably in harsh environments where metal components may rust or degrade.

Core Strengths 

The L-shaped corner force-bearing design offers excellent bending resistance and compression resistance, perfectly suitable for structural connection and reinforcement scenarios.  
2. Resistant to corrosion and rusting. It does not oxidize or corrode in acidic, alkaline, salt spray or humid environments. It requires no maintenance for long-term use.  
3. Lightweight and high-strength, with a superior specific strength compared to traditional steel and steel profiles. The construction process is more convenient and the overall cost is lower.  
4. Insulation is non-magnetic and free from electrochemical corrosion. It eliminates the risks of leakage and eddy currents, ensuring a high level of electrical safety.  
5. The size specifications are complete, allowing for on-site cutting, drilling, and assembly, and are suitable for various structural reinforcement requirements. 

Structural Characteristics 

The structure is made by using continuous glass fiber directional layup and is once solidified through the pultrusion process. The overall structure is dense without any layering. It has a standard 90° L-shaped symmetrical cross-section, with uniform thickness on both sides. It can be customized with different side lengths and wall thicknesses as per requirements. The corner transition is designed with a circular arc to avoid stress concentration. The length can be customized as needed. It can be combined with various connection methods such as bolts and adhesives. The structure is firmly connected and will not loosen or deform during long-term use.

Focusing on Performance 

The main features include high strength at the joint, excellent insulation and corrosion resistance, strong connection ability, good weather resistance and anti-aging properties. 
It is suitable for various working conditions such as structural reinforcement, frame assembly, anti-corrosion insulation, long-term outdoor use, etc. It maintains stable performance within a wide temperature range, and is resistant to impact, bending, and settlement. It meets the stable usage requirements for industrial structure connections and reinforcements.

Applicable Scenarios 

It is widely used in various industrial and construction scenarios where there is a need for anti-corrosion, insulation, and structural reinforcement, such as reinforcing the frames of chemical equipment, connecting the insulation structures of power facilities, providing anti-corrosion support for building curtain walls, reinforcing municipal guardrails, supporting the corners of storage shelves, connecting components of offshore platforms, reinforcing the frames of cold storage facilities, and connecting photovoltaic supports.
