Shelf manufacturing process is not complicated, mainly used 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, often Rack column used sheet thickness of 2.0mm, the production of raw materials is post slitting good strip, first the entire volume in the automatic punch punch Well desired hole shape, and then put it under the spare area waiting material, under the column material and roll-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 connection into one whole piece is called the column. Column piece Common colors: navy blue, light gray. 2. shelf beam production process: the shelf-shaped beam into two beams P and hold welding beams, hold welding beams are used on a large shelf, with the common use of pallets, shelves hold welding beams also called entangled beams with steel Pallets can also be used with wooden pallets, plastic pallets can also be used. Beams welded at both ends column card, the card is connected with the cargo rack column by column.
