To design and customize truly suitable heavy-duty racks, it is necessary to optimize 6 key detailed elements around the four cores of "load-bearing safety, space utilization, operation efficiency, and durability". Each element must be accurately implemented based on actual usage scenarios.

1. Core Load-Bearing Details: Ensure No Safety Hazards

Load capacity parameters of shelves/beams: Clearly define the maximum load capacity per shelf layer (e.g., 2 tons/layer, 5 tons/layer). Select shelf thickness (e.g., 3mm-8mm cold-rolled steel plate) and beam cross-sectional dimensions (e.g., 100×50mm, 120×60mm) according to the type of goods (e.g., pallets, heavy equipment). Meanwhile, calculate the connection strength between beams and columns to avoid load overload.

Column spacing and layer height: Determine the layer height based on the height of goods (e.g., total height of pallet + goods is 1.2m, with a 10-15cm operation gap reserved). Determine the column spacing according to the pallet length (e.g., 1.2m×1.0m) to ensure the pallet can be placed stably without exceeding the beam range, preventing goods from shifting or uneven stress on the shelf.

2. Space Adaptation Details: Maximize Warehouse Space Utilization

Overall rack dimensions: Determine the rack height based on the warehouse's clear height (e.g., 8m, 12m), avoiding contact with fire-fighting pipes or lamps and reserving at least a 50cm gap. Determine the rack row spacing according to the warehouse aisle width (e.g., forklift turning radius) — the one-way aisle should be ≥2.5m, and the two-way aisle ≥4m — to avoid space waste or impact on operations.

Connection between columns and the ground: If the warehouse floor has a slope or uneven load-bearing capacity, design adjustable feet (height adjustment range: 50-100mm) to ensure the rack is vertical and stable. If the load exceeds 5 tons/layer, install ground embedded plates (e.g., 10mm-thick steel plates) to enhance the connection strength between the rack and the ground and prevent tipping.

3. Operation Adaptation Details: Improve Daily Operation Efficiency

Matching access methods: If forklifts are used for goods access, install anti-collision feet (e.g., 100×100mm square tubes) on both sides of rack columns to avoid forklift collisions. If stackers are used, clarify whether the edge of the rack shelf needs anti-slip treatment (e.g., embossing, installing rubber strips) to prevent goods from slipping. If manual assistance is required, install step bars under the shelf to facilitate climbing for goods retrieval.

Goods positioning and marking: Reserve sign installation positions (e.g., card slots, hooks) on rack columns or beams according to the needs of goods classification, making it easy to post location numbers. If goods have temperature and humidity requirements, reserve ventilation holes (hole diameter: 5-10mm, spacing: 10cm) under the rack shelf to ensure air circulation.

4. Durability and Protection Details: Extend Rack Service Life

Material and surface treatment: Prioritize Q235B cold-rolled steel (high tensile strength, good toughness) for columns and beams. Adopt electrostatic spraying (thickness: 60-80μm) or hot-dip galvanizing for the surface to prevent rust caused by moisture and dust, which is especially suitable for special warehouses such as food and chemical warehouses.

Reinforcement of vulnerable parts: Install buckles or screws at the connection between shelves and beams (to avoid shelf displacement). If light goods need to be placed on the top of the rack, install top beams (connecting columns of adjacent racks) to enhance overall stability. If there is vibration in the warehouse (e.g., equipment nearby), install shock-absorbing pads at the bottom of the columns.

5. Compliance Details: Meet Safety Standards

Adaptation to fire protection and lighting: Arrange racks to avoid fire hydrants and fire extinguishers, ensuring unobstructed fire-fighting access. If the rack height exceeds 6m, reserve lighting installation space (e.g., installing LED strip lights) between racks to avoid dim light during goods access.

Clear load marking: Mark the maximum load capacity label (e.g., "Maximum Load: 2000kg") at a prominent position on the rack column (e.g., under each layer of beams) to prevent employees from placing goods beyond the load limit, complying with the requirements of the "Warehouse Rack Design Specification" (GB/T 27924-2011).

6. Customization Adaptation Details: Meet Special Needs

Adaptation to special goods: For storing ultra-long goods (e.g., pipes, profiles), design cantilever heavy-duty racks (cantilever length determined by the length of goods, e.g., 1.5m, 2m). For storing wheeled equipment (e.g., small machinery), install edge guards (height: 5-10cm) on the shelf surface to prevent equipment from sliding.

Reservation for future expansion: If the warehouse may need to increase load capacity or expand the number of racks in the future, use modular columns (layer height can be adjusted by adding or removing beams) and reserve connection holes during design, facilitating the addition of rack rows or layers later and avoiding repeated modifications.

These details need to be comprehensively optimized based on your specific needs (e.g., goods type, warehouse size, access equipment) to ensure the rack is "truly suitable".
