Corrosion Resistance
FRP structural products are corrosion resistant to a broad range of chemicals. In many structural applications where wood rots and metals corrode, pultruded FRP products will last indefinitely with little or no maintenance.
Strength
Stronglite's pultruded structural shapes have a high strength-to-weight ratio and pound for pound are stronger than steel in the lengthwise direction.
Weight
FRP materials are light weight. Generally on an equal volume basis, pultruded fiberglass will weigh only 25% of the weight of steel and 70% of the weight of aluminum. This feature can significantly impact installation costs, reduce the risk for injury and result in less structural support from foundations or supporting structures.
Electrical Conductivity
Fiberglass products are extremely low in electrical conductivity. Non-conductive products provide significant safety benefits in many applications such as those found in electrical substations products and power poles.
Thermal Conductivity
Fiberglass products are low in thermal conductivity and FRP products do not expand or contract like metals. This feature can provide a significant degree of thermal insulation.
Ease of Fabrication
FRP can be field fabricated using simple carpenter tools with carbide or diamond tip blades; no torches or welding is required. Fiberglass materials are also lightweight, resulting in easier erection and installation.
