The beam of the weighing platform adopts advanced U-shaped steel technology and weld process protected with carbon dioxide gas, which makes the structure of the system advanced and reasonable, the strength, bending resistance and torsion resistance meet the requirements of national regulation. The surface of the weighing platform is coated with two layers of hi-qualified antirust primer and two layers of fine qualified top coat, and with the traffic lane lined out.
