Fiberglass is a common type of plastic, reinforced with glass fiber. It can be molded into a variety of shapes and is stronger than many metals. It is cheaper and more flexible than carbon. Fiberglass square tube stock is noncorrosive with high impact strength. It is lightweight and resists insect damage.
Pultruded glass fiber reinforced structural shapes and plate have a number of significant advantages over materials commonly used for structures including timber, steel, and aluminum in many structural, electrical, and environmental applications. Pultruded fiberglass is highly corrosion resistent. Like wood might, pultruded fiberglass will not rot or decay and is not susceptible to insect attack. Unlike wood, fiberglass requires no environmentally unfriendly preservatives or repellants, does not absorb any significant amount of water and is consistent in strength and appearance piece-to-piece (no culling). Pultruded fiberglass is stronger, more rigid and lighter weight than structural timber. Pultruded glass fiber reinforced structural shapes and plate are electrically and thermally non-conductive, impact resistant, and EMI/RFI transparent. Square tubes are a great option for your structural needs.
Above all these structural profiles are particularly popular in corrosive environments. They are used in galvanizing processes; chemical, petrochemical and water treatment systems. They can be also used for cooling towers; offshore installations; construction areas and the inside of underground transport system tunnels.
Furthermore they are popular in situations requiring mechanical performance combined with resistance to corrosion, insulation, lightness and elasticity. Because of their mechanical characteristics, they are used for constructing scaffolding during building renovations, deck framing and pedestrian bridges.
As a result, they offer outstanding ease of assembly and maintenance free performance compared to other materials such as wood or metal.
