FRP Square Tube

FRP square tube has been optimized in terms of strength and mechanics. Its strength has been greatly improved to be close to or even higher than that of steel tube, and the toughness maintains the performance of FRP.

FRP square tube is generally used as a component or a part of FRP products. For example, most of the piles of FRP sign piles are square tubes or part of the railings and guardrails, as well as supporting beams in some work platforms.

The requirements for FRP square tubes are different in different environments. FRP square tubes are generally produced using alkali-free fiberglass and Orthophthalic resin. In severely corrosive environments, the vinyl resin with excellent corrosion resistance is required.

FRP square tubes of most specifications can be directly transported manually, which is particularly easy to install, reducing the use of machinery. In view of the fact that FRP square tube is non-metal, there is no risk of fire caused by the collision sparks, it is very safe.

◆ Common size of FRP square tube

The length of the FRP square tube can be customized to reduce the number of joints: the long length reduces the number of joints needed in long-distance pipeline installations, which reduces construction costs and reduces leakage.

Q1: How do you ensure the quality of FRP products?

A: All products are manufactured in our own factory under strict ISO-based quality control. We perform raw material testing, process monitoring, and final inspection to ensure every panel meets strength, durability, and corrosion-resistance requirements.

Q2: Where can FRP products be used?

FRP products are ideal for chemical plants, wastewater facilities, offshore platforms, walkways, platforms, stairs, and other areas that require corrosion resistance, lightweight structure, and long service life.

Q3: Do you provide after-sales support?

Yes. We provide clear documentation, installation guidelines (if needed), and technical support. If any quality issue is confirmed after delivery, we offer replacement, rework, or other agreed solutions.

Q4: Can you help with project-specific requirements?

Absolutely. Our team can suggest the right resin system, grating type, and surface finish for your application, and provide drawings or design assistance to ensure project success.
