As the core carrier of warehousing and logistics, the forming process of industrial shelves directly impacts their load-bearing capacity, durability, and cost-effectiveness. Modern industrial shelves are primarily constructed from sheet metal (such as cold-rolled steel and galvanized steel). The forming process incorporates numerous precision manufacturing technologies to ensure structural stability, safety, and reliability.
Material pretreatment and cutting are the first steps in the shelf forming process. High-quality steel undergoes leveling, rust removal, and surface treatment (such as electrostatic spraying or hot-dip galvanizing) to enhance corrosion resistance. Laser cutting, plasma cutting, or CNC punching are then used for precise blanking, ensuring that each component's dimensional tolerance is within ±0.5mm, laying the foundation for subsequent assembly.
Bending and welding are key steps in the shelf forming process. A hydraulic press brake forms the steel sheets to the designed angle (typically 90° or custom angles) to form the main structural components, such as columns and beams. Welding is performed using automated gas shielded arc welding (MIG/MAG) or resistance spot welding to ensure weld strength and aesthetics. Columns typically feature multiple holes for easy height adjustment, while crossbeams and columns are connected using high-strength bolts or clips for quick assembly and disassembly.
Surface treatment and quality inspection are the final steps in ensuring shelf life. Shelves undergo a plastic spray or dip coating to create a wear-resistant and rust-proof finish. Some high-end products utilize hot-dip galvanizing, achieving salt spray resistance of over 1,000 hours. Finished products undergo load-bearing tests (such as a static load of 1.5 times the design load), dimensional verification, and weld non-destructive testing to ensure compliance with industry standards (such as GB/T 23824 or FEM 10.2.02).
With the advancement of intelligent manufacturing, shelf forming is increasingly incorporating technologies such as robotic bending and 3D modeling pre-verification to further improve precision and efficiency. In the future, lightweight alloy materials and modular design may become key areas of process innovation.
