　　1. Composition: The steel platform structure usually consists of planking, primary and secondary beams, columns, inter column supports, ladders, and railings.

　　2. Classification: It can be divided into indoor and indoor platforms, static and dynamic load bearing platforms, production auxiliary platforms, medium and heavy operating platforms, etc. According to different treatment methods of bearings, the platform structure can also be divided into:

　　1) They are all independent platforms. For platforms with large dynamic loads or heavy equipment, they should be separated from workshop columns and directly supported on independent columns.

　　2) A platform directly placed on a workshop column tripod or bracket, usually with a safe passage function or a simple medium-sized operating platform.

　　3) One side is supported on the factory column or building wall, and the other side equipped with an independent column platform.

　　Standard for Acceptance of Storage Supermarket Shelves

　　Step 1: Confirm whether the received shelves are delivered in accordance with the order, with complete accessories, matching colors with the samples, and packaging meeting the requirements.

　　Step 2: Overall installation accuracy inspection of shelves

　　1. The vertical deviation of shelf pieces shall not exceed 10mm;

　　2. The height deviation of the same floor crossbeam is ± 10mm;

　　3. The deviation of the center distance between the bottom of adjacent shelf columns is ± 2mm;

　　4. The misalignment deviation of shelves in the same lane and column shall not exceed 5mm;

　　Step 3: Inspection of shelf manufacturing accuracy:

　　1. The column is punched and rolled using imported CNC machine tools, with an error of ± 2mm in the first and last holes;

　　2. When fully loaded, the curvature of the inner and outer sides of the column should be less than H/1000, and the deflection of the beam load should be less than L/250;

　　3. The rigidity and strength of the shelves comply with the mechanical industry standard GB/5323-91;

　　Step 4: Surface treatment process:

　　Black body - removal of surface dirt - chemical rust removal - phosphating - spray molding - leveling solidification - packaging inspection and warehousing, with a coating thickness of 60 microns.
