Welded Storage Rack Process Features
The welding rack process focuses on three core objectives: structural strength, dimensional accuracy, and durability. Specific features are as follows:
1. Highly adaptable process, meeting diverse needs
Flexible raw material selection: Metal materials of varying materials can be selected based on the application scenario, such as ordinary carbon steel (low cost, suitable for dry environments), stainless steel (corrosion-resistant, suitable for kitchens and humid warehouses), and aluminum alloy (lightweight and easy to move), meeting the performance requirements of racks in different environments.
Targeted welding method adaptation: The welding method is selected based on the material and load-bearing requirements. For example, arc welding is commonly used for carbon steel components (high efficiency, low cost, suitable for mass production), while argon arc welding is commonly used for stainless steel or thin-walled pipes (produces aesthetically pleasing welds, high-quality welds, and reduces corrosion risks), ensuring a balanced strength and appearance of the weld joints. 2. Outstanding Structural Stability and Reliable Load-Bearing Performance
High-Strength Joint Welding: Key load-bearing locations (such as the connection between columns and beams, and the connection between shelves and frames) utilize "full weld" or "reinforced weld" techniques to avoid cold and leaky welds. The welds are highly integrated with the parent material, effectively distributing the load, ensuring that each floor can stably bear the designed weight. Long-term use reduces the risk of frame deformation and shelf collapse.
Pre-treatment and Strengthening the Structure: Before welding, components undergo pre-treatment processes such as bending and reinforcing the shelf edges to improve deformation resistance and welding column connectors to enhance the stability of the connection to the beam, further enhancing overall structural rigidity. 3. High Precision and Controllability, Guaranteed User Experience
Small Dimensional Error: During the welding process, fixtures are used to secure component positions, ensuring vertical alignment between columns and beams, alignment of shelves and frames, and uniform spacing between shelves (typically within ±2mm). This prevents problems such as frame tilt and shelf misalignment, ensuring the shelf's appearance is uniform and compatible with standard-sized storage boxes and items.
Post-Welding Finishing: After welding, the weld seams are polished with tools such as an angle grinder and sandpaper to remove slag and burrs, resulting in a smooth surface. This not only enhances the appearance but also prevents scratches and damage to stored items during use. 4. Perfect Surface Treatment Extends Service Life
Excellent Corrosion Protection: Surface treatments such as pickling and phosphating (removes rust and oil stains from the metal surface and enhances coating adhesion), electrostatic spraying (forms a uniform, wear-resistant protective coating that resists scratches and aging), and galvanizing (suitable for humid environments and enhances rust resistance) are selected based on the operating environment. This effectively isolates the metal from air and moisture corrosion, ensuring the shelf's long-term use in environments like balconies and warehouses (with a service life of 5-10 years under normal maintenance).
Stable Coating Quality: The surface coating thickness is controllable (typically 60-120μm for spraying), and high-temperature curing ensures strong adhesion, resists flaking and sagging, and maintains its appearance and color over time.
