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.

Another key advantage is that pultrusion material is lighter in weight than structural timber, but at the same time pultrusion is still much stronger and more rigid.

Liberty Pultrusions Structural Composites have “built-in” ultraviolet and weather protection and are corrosion resistant. There is no need to apply costly coatings, preservatives or films, like you would need to if using wood.
