Fibreglass Square Tube

Fibreglass square tube is an excellent substitute for steel and aluminum tubes due to its lightness, insulation, high strength, and resistance to high corrosion in harsh environments.
✔️ Factory Direct Sales.
✔️ Customized Dimensions & Multi-usage.
✔️ Multiple Color Options.

In the construction of the city, you will see a lot of fences made of fibreglass square tubes, which are used to replace wood, aluminum, or steel fences that are exposed to various kinds of stress and atmospheric events. Thanks to the performance benefits including bright color, high durability, virtually no maintenance, high strength-to-weight ratio and low expansion/contraction rates, they beautify the environment while bringing a very good practicality. In addition, the lightness of the material also makes it easy to handle and install, optimizing time and money without all the maintenance operations that steel requires.

We not only produce fibreglass square tubes, but also other fiberglass structural shapes. They can be manufactured in any desired shape and customized profiles for any structural application to help you meet every construction or manufacturing challenge, from light duty to heavy duty.

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.
