Fiberglass grating bars are often used in industrial and construction applications for their strength, durability, and corrosion resistance. They’re made from fiberglass reinforced plastic (FRP), which is a composite material consisting of a polymer matrix reinforced with fibers. The main advantage of fiberglass over traditional materials like steel is its resistance to rust, chemicals, and its non-conductive nature, making it ideal for electrically hazardous environments or where chemical exposure is common.
