Pultruded FRP Profiles for Corrosive & Demanding Environments

FRP (Fiber Reinforced Polymer) profiles are manufactured by the pultrusion process, where continuous glass fiber rovings, mats, and surface veils are pulled through a resin bath and heated die to form strong, lightweight structural shapes. The most common profiles include round tubes, square tubes, rectangular tubes, I-beams, U-channels, angles, T-sections, and flat bars.

These profiles offer outstanding corrosion resistance to a wide range of chemicals, salt water, and environmental exposure, making them an ideal alternative to steel, aluminum, and wood in corrosive or electrically sensitive applications. They are non-magnetic, non-conductive, and have high strength-to-weight ratio, providing long service life with minimal maintenance.

We supply FRP profiles for overseas distributors, construction companies, industrial buyers, maintenance companies and OEM customers, with different shapes, resin systems, dimensions, lengths and custom fabrication available according to specification.

Excellent Corrosion Resistance Resists acids, alkalis, salt water, and most industrial chemicals without protective coatings.
High Strength-to-Weight Ratio Lighter than steel (about 1/4 the weight) while offering comparable or higher strength.
Electrical Insulation Non-conductive and non-magnetic, ideal for electrical and communication applications.
Custom Shapes & Dimensions Round tubes, square tubes, I-beams, U-channels, angles and custom profiles available.
Material Advantages

Why Choose FRP Profiles?

FRP profiles combine corrosion resistance, lightweight construction, high strength and electrical insulation, making them superior to traditional materials in many demanding environments.

01

Superior Corrosion Resistance

FRP profiles withstand aggressive chemicals, salt spray, moisture and UV exposure without rusting or degrading, reducing maintenance costs.

    FAQ

    Frequently Asked Questions About FRP Profiles

    What are FRP profiles?
    FRP (Fiber Reinforced Polymer) profiles are pultruded structural shapes made from glass fiber reinforcement and thermosetting resin. They are used as lightweight, corrosion-resistant alternatives to steel, aluminum and wood.
    What shapes are available?
    Common shapes include round tubes, square tubes, rectangular tubes, I-beams, U-channels, angles, T-sections and flat bars. Custom profiles can also be produced based on drawings.
    What resin systems are used?
    Typical resin systems include unsaturated polyester for general use, vinyl ester for superior chemical resistance, and epoxy for higher temperature and mechanical performance.
    What is the maximum operating temperature?
    Polyester-based profiles can typically be used up to +120°C continuously. Epoxy-based profiles can withstand up to +150°C depending on the specific formulation.
    Can FRP profiles be cut and machined?
    Yes. FRP profiles can be cut, drilled, and machined using carbide or diamond tools. Proper dust collection is recommended during machining.
    Are FRP profiles fire resistant?
    Standard FRP is combustible but can be formulated with fire-retardant additives to meet specific flame spread and smoke requirements.
    Is FRP profile RoHS compliant?
    RoHS compliance can be provided for applicable resin systems and documentation requirements. Please confirm when requesting a quotation.
    What information do you need for a quotation?
    Please provide the profile shape, dimensions, length, resin system preference, quantity, and any special requirements such as fire rating or UV resistance.
