As a key type of pultruded fiberglass profile, the fiberglass round tube is a thermoset composite product manufactured through high-temperature pultrusion technology. It is made using high-strength fiberglass roving, stitched mat (or continuous strand mat, polyester mat), and high-quality thermosetting resins such as unsaturated polyester or vinyl ester resin.

    These tubes are known for their high strength and corrosion resistance. With wall thicknesses ranging from 3mm to 20mm and a variety of colors available (such as yellow and green), they can withstand compressive strengths up to 1000 MPa.  Lightweight and easy to install, they are widely used in power systems, industrial plants, tunnels, and more.

    Formed precisely through advanced pultrusion equipment, fiberglass round tubes offer excellent mechanical properties along with outstanding resistance to corrosion, heat, and weathering. Also known as fiberglass circular tubes, they have become a preferred solution in industries like construction, transportation, and chemical processing.

Customer Feedback:

Allen
    "I live by the sea, and the metal railings on my balcony started rusting after just two years. I replaced them with fiberglass round tubes, and even after five years of sun and sea wind, they’re still like new—no corrosion, smooth surface. They’re lighter than iron pipes, easy to install alone, and best of all, they’re non-conductive, so I don’t worry about safety during storms. Whether it’s for outdoor fencing, garden supports, or DIY flower racks, they’re strong, safe, and look great. I chose fiberglass round tubes from Henry Environmental Equipment—they’re well-made, perfectly cut, and very precise in dimensions. It’s really added a sense of safety to my home.”
