Rows of drains can be seen on roads with heavy traffic or construction sites with fork truck traffic. Have you ever been worried about serious accident caused by the theft or corrosion of the drain gratings due to caustic conditions? When heavy stainless steel gratings for drains carry heavy traffic vehicles, they are prone to bend and break easily, causing serious traffic accidents too. Safety is top priority! Find the right solution is critical to maintain a safe environment.
Whether you need a large open area for fast draining or tight grate openings for ADA surfaces, heavy duty GRP grating for drain is an excellent alternative to heavy steel gratings in heavy loads at long spans applications in corrosive environments. Although pultruded heavy duty GRP gratings can also be used for very long spans, when it comes to heavy vehicular traffic, molded heavy duty GRP grating is more widely used due to its more reasonable price and excellent bi-direction strength under loadings up to standard truck (H-20).
