Fiber Reinforced Plastic (FRP) pultrusions are used in many types of applications throughout many different industries. The pultrusion process allows Liberty Pultrusions to produce continuous lengths of fiber reinforced polymer (FRP) profiled shapes.
Pultrusion material holds a lot of value over other types of materials that you may be considering for your next construction project or application.
Pultruded products are non-conductive
corrosion resistant, strong, durable and
lightweight, among other versatile
and cost-effective properties.
Depending on the class of polyglas structural pultrusion profiles, FRP pultrusion may also be made to be fire-retardant.
Polyglass electrical pultrusion has these same great properties and can also be manufactured as non-magnetic, UL listed, arc and track resistant and fire-retardant.
In comparison to metal and wood, pultrusions are much more lightweight (75% more lightweight than steel and 30% more lightweight than aluminum), which can make a tremendous difference in many industries including transportation, aerospace, sporting equipment and many others.
Another advantage is that steel, aluminum and other metals have isotropic properties, or equal strength in every direction. FRP Pultruded profiles on the other hand, can have applied reinforcement where it is needed, allowing for more efficiency.
Benefits of Pultrusion Over Wood / Structural Timber
The most obvious advantage of pultruded material over wood is that pultrusions will not rot, mildew, mold or warp due to weather or moisture exposure. They are also not at risk for insect infestation. And unlike wood when wet, FRP pultrusion is non-conductive, making it a much safer material for many types of applications.
