Heavy-duty beam-type shelves

Heavy-duty beam-type racks (also known as pallet racks) are standardized heavy-duty storage core equipment in the industrial warehousing field. They comply with the national standard GB/T 27924-2011 and feature the core advantages of "super load-bearing capacity, flexibility and versatility, safety and efficiency". They are suitable for large-scale storage of full palletized goods. It is the preferred solution for manufacturing and logistics centers to maximize space and achieve efficient operations. It has the following features: 1. Super strong load-bearing specifications: The single-layer rated load-bearing capacity is 500kg-5000kg, fully covering the heavy-load requirements of industrial grade, and is suitable for bulk goods such as palletized building materials, mechanical parts, chemical drums, and auto parts. 2. High-specification materials and structure: The main body is made of Q235B or Q345 high-strength steel, and the columns are formed by the "pre-punching and cold-bending" process. The cross-sectional width is 60-150mm and the wall thickness is 1.5-4.0mm to avoid internal stress concentration. The crossbeam adopts double C-shaped steel welded beam or P-shaped closed beam, with a section height of 40-60mm and a wall thickness of 1.5-2.0mm. It has excellent bending and torsional resistance. Combined with 3mm thick stamping hangers, the force-bearing contact surface is increased, and the load-bearing is more stable. 3. All-round safety design: The crossbeam is connected to the column through three-pronged hangers and clips, and is equipped with L-shaped safety pins formed by stamping 3mm steel plates to prevent the crossbeam from falling off due to external force impacts. A 10# Angle steel anti-collision foot guard is installed at the bottom of the column. A 70mm diameter anti-collision guardrail can be added on the side of the passage, with a 1.2 to 1.5 times dynamic impact safety margin reserved to adapt to the high-frequency operation scenarios of forklifts. 4. Multi-dimensional adjustment and expansion: The columns are pre-set with standard pitch adjustment holes of 50mm/75mm, and the layer spacing can be freely adjusted to adapt to palletized goods of different heights. The net length of the cargo compartments is 2000-3100mm, and the depth of the column sections is 800-1400mm. It supports customizing the width and height as needed (conventional ≤12 meters). The modular structure can be infinitely spliced end to end, and accessories such as shelf boards and grid cross beams can be added to derive variants such as double depth and narrow aisles. 5. Convenient assembly and maintenance: It adopts a fully assembled structure, which is combined by bolt fastening and plug-in connection without welding. Professional teams can complete the installation quickly. The surface is treated with acid washing, phosphating and electrostatic spraying. In damp environments, thickened galvanizing process can be selected to prevent rust and corrosion. Damaged parts can be replaced separately, and the maintenance cost is low. 6. Efficient access and retrieval adaptation: Open storage position design allows forklifts to directly enter the aisle for full pallet access and retrieval. Each pallet can be operated independently without moving other goods, supporting first-in, first-out or free picking strategies. The space utilization rate is more than 1.5 times higher than that of flat stacking, and the access efficiency is 50% higher than that of ordinary shelves. It is compatible with various types of forklifts such as counterbalanced and reach trucks.
