Shelf manufacturing process is not complicated, mainly used in cutting machines, bending machines, presses, spot welding, cutting machines and other equipment. 1. Rack column production process: post classified as 90 columns, 80 columns, 55 columns, commonly used shelf column sheet thickness of 2.0mm, the production of raw materials is slitting good column strip, the entire volume of the first automatic punch punch need good hole shape, and then place it in the spare area waiting for the next feeding, cutting and rolling uprights forming is accomplished simultaneously. Common column height is 2 m, 2.5 m, 3 m, 4 m, 5 m, 6 m. Rack column and crossbars and bracing with screw connections into a whole piece is called the column. Column piece Common colors: navy blue, light gray. 2. shelf beam production process: P shelf beam into two beams welded girders and hold, hold welding beams are used on a large shelf, with the common use of pallets, shelves hold the beam welding is also called entangled beams with steel pallets, can also be used with wooden pallets, plastic pallets can also be used. Beam welding ends of the column, the card is connected with the cargo rack column by column.
