Production Process

SSG’s gratings are manufactured by a precise, high speed, computerized control equipment that combines intense hydraulic pressure (120 ton) with a powerful electric current (2500 KVA) to electro-forge the cross bars and bearing bars into a single rigid standard panel. This one piece construction not only eliminates cracks or open joints that might harbor moisture or other corrosive material but shaping can also be done to a great extent without destroying or reducing rigidity and strength of the metals. The square twisted steel cross bars of SSG’s gratings provide excellent traction, walking surface and increase load bearing ability. The SSG’s electro-forged machine has the flexibility and capability of welding a wide range of bearing bars and cross bar sizes.
