Whether it’s a private residence, commercial carwash, or industrial facility heavy duty (HD) fiberglass grating has become the most suitable primary structural material due to the superior load capacity, impact resistance and excellent corrosion resistance in harsh environments. Mach’s heavy duty fiberglass grating is strong enough to withstand vehicular loads in a wide array of industries. It can load from transport trucks (H-20) and forklifts and will never warp/rust/corrode and become unsafe, which provides the most durable and lowest maintenance solution in harsh environments!
Our HD fiberglass grating is available in molded and pultruded options to suit all kinds of applications, for example, our heavy duty square mesh is also ideally used as the floor for adult cattle. No more safety hazards and high maintenance costs caused by warped steel gratings, please feel free to consider our heavy duty fiberglass grating!
