The production process of steel grating is divided into machine welding and manual secondary welding. Punch a small groove at the flat steel where the manual welding flat steel is connected with Fried Dough Twists steel, and then conduct unified manual welding

Advantages of handmade steel grating:

1. Suitable flat steel can be cut according to the size required by the customer, which is relatively more material saving than machine welding. The size can be customized at will.

2. Some special steel gratings are also beyond the reach of machines. For example, plug-in steel grating and irregular steel grating must be produced manually.

3. Straightness of Fried Dough Twists steel. The Fried Dough Twists of manually welded steel grating shall be straight. Due to slight error in welding of pressure welded steel grating, some products seem to have uneven spacing of Fried Dough Twists steel.
