Your Source for Fiber-Reinforced Plastics in the Sarnia Area

Reinforced Polymer Materials

Fiber-reinforced plastic is a composite material that is composed of a polymer material that has been reinforced with glass, carbon, basalt or aramid fibers. FRPs are commonly used in a number of industries, including aerospace, automotive and marine, and construction. L & M Fiberglass offers a selection of FRPs for a number of applications. Contact our office to learn more.

FRP Grating

A high strength material for stairway components, plant flooring, machinery guards, and wash racks, is fabricated from continuous glass fibers impregnated with chemical resistance and flame retardant polyester resin. A good electrical insulator, it is much lighter in weight than steel grating so it requires less structural support.

Exhaust Hoods

For ventilating open process tanks offer important advantages when manufactured from fiberglass reinforced plastic. These include outstanding chemical resistance, very light weight, and long service life with virtually no maintenance required.

Air Louvres

Resistance to corrosive and high humidity environments make FRP the ideal material for louvres that open and close under pressure to admit make-up air into process plants.

FRP Pipes

Made from specially selected resins, FRP pipes can be tailored to provide excellent resistance to most acids, alkalis, salts, and organic liquids or gases. Less costly that other corrosion resistant pipe materials, FRP has better low temperature properties that the thermoplastic pipe and will withstand high temperatures often encountered in processing.

Fume Scrubbers

Made of FRP are generally less expensive than those made of lined or stainless steel, and usually have a longer service life. The light weight of these scrubbers also permits their installation on roof areas without adding supporting steel work, freeing up valuable floor space for other plant equipment.
