shelf production specifications and related standards design production specifications:
shelf design production the installation implementation standards are as follows: 1. cecs23:90 "design specification for shelf structures" 2. gb50017-2003 "design code for steel structures" 3. gb6723-86 "universal cold formed steel size, weight shape and permissible deviation" 4. the mechanical properties of bolts meet the performance requirements specified in gb/t3098·1-2000. design basis: maximize the use of the site and strictly follow the user's requirements. production technology process introduction: raw materials → cold roll forming → cut length, flat head → punching (welding) → calibration → surface spray → packaging → finished product 1. raw materials: all shelf components are made of cold-formed profiles using high-quality raw materials. 2. automatic punching: it has a fully automatic continuous steel strip punching production line for completing the punching of the column profile before rolling. 3. cold roll forming: the rack posts and various cross beams are rolled by their own independent numerically-controlled cold-formed forming units, automatically positioned and cut according to the desired length. 4. welding: all welding with carbon dioxide protection welding machine, the main welding seam welding is automatic, to ensure the quality of the weld and the smooth and beautiful weld. 5. surface treatment: the electrostatic spraying production line is used, and the domestic fine powder is selected. the specific process is: 1) black blank → remove surface dirt → chemical derusting → pickling → phosphating → surface spray → constant temperature solidification → finished product; 2) epoxy powder electrostatic spraying process is applied on the surface of the shelf, and the coating thickness is 60-80 μm; 3) electrostatic dusting adhesion meets level 0 requirements in gb92865-88; 4) the hardness (wear resistance) is more than 100 times that of common lacquer, meeting the 2h requirement of gb 6739-86 standard weight; 5) corrosion resistance (hydrochloric acid test) gb1771-91 is greater than 500 hours.
