Heavy duty steel grating is designed for heavy load occasions. Heavy-duty steel grating is formed by the pressure welding process of large-size bearing bar through high temperature and pressure. Due to the particularity of heavy load, heavy duty steel grating is generally made of bearing bar that is wider and thicker (6 mm, 8 mm, 10 mm). Heavy duty steel grating bearing bar spacing is generally 30mm, cross bar spacing can be 50mm and 100mm. Heavy duty steel grating can be made by pressure welding or pressure lock. It’s widely used for airports, highways, industrial platforms, port terminals and other special needs of the occasion.
