Production process: 

 I produced the Shelves standard high prices 2300mm pitch of 900mm, width 510/560mm standard level books for six layer, the layer from 320mm on each partition uniform loading capacity 80kg. The frame structure frame and box type, with the safety limit and anti-down device, to form a completely closed between columns. Any special requirements, we designed a special manufacture. 

 (2) each column Shelves are equipped with a brake, open and close easily. Open-shelf accessible resource data, simply press the brake handle, the frame body will not move by others, can effectively guarantee the personal safety of inspection personnel. 

 Transmission precision HR1204 double beads cast aligning bearing, motorcycle chain drive beads with 45 # solid steel, double live transmission, mobile and flexible, shaking light. 

 4 Shelves each column equipped with a magnetic attraction between the rubber seal devices, the seal anti-aging processing. Equipped with a dust board at the top of the frame body at the bottom with anti-rat files, empty seam close to the fire, dust, theft prevention, anti light requirements. 

 Rack part to strengthen the disc's overall frame plate and buckle hook to hang board, board assembly, flat solid. Gear automatic gear knot loose shake when you are free to stop the vertical position, the foldable handle, in order to avoid obstacles to movement. 

 The chassis frame combination segmented modular welded chassis, high precision machining, good docking interchangeability, section type a wide range of advantages. 

 7 rail 20 * 20 square steel rail seat welded from 3mm steel plate bending forming, spray the surface, rails embedded style ground tiled two, embedded track capped with cement on the ground. requirements cushion solid formation, the rail Puwan before making the surface layer. Ground laying track is mounted directly on the ground has been completed. Track with the ground connection for the introduction of expansion screws fixed. 

 Our products are mainly raw materials, cold rolled steel, all the high quality steel plate of Shanghai Baosteel, technology standard meet GB/T11253-8 standards, material ST12 and Q195 AT-235. 

 The surface treatment process: surface treatment using the emulsifying agent and alkaline to help wash degreasing, phosphoric acid rust, zinc phosphide thin film, passivation, the final powder coating. Decorative and protective properties, strong adhesion. The frame processing methods and the outer surface of the body wall of the treatment is the same.
