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. They can be up to 4″ wide.
