Fiberglass Square Tube

Fiberglass rectangular tubes, crafted from glass fibers and thermosetting resins, offer a robust and versatile material solution characterized by exceptional durability and lightweight design. These tubes boast an array of beneficial properties including high strength, corrosion resistance, electrical insulation, and significantly low thermal conductivity, making them ideal for a wide range of industrial applications. From the oil sector and power engineering to sewage treatment and marine exploration, FRP square tubes are extensively used as operational platforms, stairways, and covers, providing an optimal support structure in corrosive environments.

What Is The Application Of The Fiberglass Square Tube?

Industrial Applications

Fiberglass square tubes are commonly used in industrial settings to fabricate items like railings, fixed ladders, and floor grating. Their strength makes them capable of bearing weight in these applications safely

Structural Framing and Columns

They can be used as structural framing or as columns, providing a lightweight yet sturdy alternative to traditional materials like wood or metal.

Communication Infrastructure

Fiberglass is naturally RF transparent, making it useful in many radome and communication applications. It does not interfere with Wi-Fi, Bluetooth, or other wireless signals, which is a significant advantage in today’s connected world

Corrosive Environments

Fiberglass square tubes are a perfect fit for corrosive environments like wastewater treatment plants, industrial and chemical plants, and areas with salt air and pollution corrosion


They are used in architectural paneling, bridge decks, building facades, catwalks, marine docks, sun screens, water screens, walkways, railing infill, and security partitions.

Chemical Industry

Fiberglass square tubes are widely used in these industries due to their corrosion resistance, low thermal insulation coefficient, and adaptability to environmental requirements

Key Advantage Of Fiberglass Square Tube

  • Enhanced Durability:Their high strength mitigates the risk of damage from accidental impacts.
  • Lightweight Nature:They are significantly lighter than traditional materials, being up to 80% lighter than steel and 30% lighter than aluminum, which simplifies installation and handling.
  • Corrosion Resistance:These tubes are impervious to a wide array of corrosive chemicals and environmental conditions, ensuring longevity.
  • Thermal and Electrical Insulation:With thermal conductivity much lower than metals and inherent electrical insulation properties, they are safe and efficient for use in varied temperature and electrical contexts.
  • Maintenance Ease and Aesthetic Flexibility:Their design facilitates straightforward installation and low maintenance, while a broad selection of colors allows for aesthetic versatility.
