High-quality fiberglass is typically composed of pure silica sand and is treated with chemical inhibitors to enhance its resistance to corrosion High-quality fiberglass is typically composed of pure silica sand and is treated with chemical inhibitors to enhance its resistance to corrosionfiberglass duct corrosion resistance. On the other hand, lower-quality fiberglass may contain impurities or lack adequate protection, making it more prone to corrosion.Fiberglass plates feature a non-conductive surface that makes them an economical and safe solution to walking surfaces. In caustic and/or acidic conditions, fiberglass plates provide a level of corrosion resistance that is unequaled and more cost effective than stainless steel. Fiberglass plate is available with a non-grit surface, or with a grit surface where anti-slip traction is needed. For more on fiberglass plates, click here.
