Custom OEM Medium Duty Racking System Suppliers & Exporters

The distinction centers on load-bearing mechanics, upright column gauge, and handling interfaces. Light-duty slotted angle shelving handles 50–150 kg per shelf tier, utilizing single-piece corner gusset plates for light archival or retail stock. Medium-duty longspan shelving spans 200–800 kg per level, utilizing cold-formed omega upright posts (typically 55×47mm or 60×50mm) and interlocking step beams intended for manual carton hand-loading. Heavy-duty pallet racking starts at 1,000 kg and reaches over 4,000 kg per level, designed with larger upright profiles (80mm to 120mm web) specifically engineered for forklift mast interaction and heavy timber or steel pallet storage.

Yes. Structural engineering for seismic regions is calculated using local ground acceleration factors ($S_s$ and $S_1$ response spectra). We reinforce the base upright frames with widened, high-ductility footplates (minimum 6mm to 8mm thickness), increase concrete anchor bolt embedment depth (using heavy chemical or M10/M12 wedge anchors), and integrate horizontal and diagonal back-frame bracing trusses to absorb cyclic kinetic energy without shear failure.

Selection depends on fire codes and ambient environmental factors. Cold-rolled SPCC steel laminates with bottom stiffener ribs provide a smooth, ultra-durable, wash-down compatible surface ideal for automotive parts and high-cleanliness electronics warehouses. Galvanized wire mesh decking is mandatory in facilities requiring compliance with NFPA overhead fire sprinkler water penetration regulations and cold-storage airflow circulation. Wood/particle board is cost-effective for dry, temperate storage but is vulnerable to warping and mold in tropical Southeast Asian relative humidity (>80%).

Every component undergoes a 5-stage automated surface conversion process prior to powder application: high-temperature alkali degreasing, acid pickling to strip mill scale, clean water neutralization, and microscopic iron/zinc phosphating. This chemically bonds a corrosion-inhibiting crystalline layer to the steel substrate. Finally, our electrostatic robotic paint line applies premium thermoset polyester powder baked at 180°C–200°C, achieving 60–80 μm film thickness and over 500 hours of continuous neutral salt spray resistance (ASTM B117).

To provide an accurate engineering proposal, we require: (1) Warehouse building CAD drawings showing clear ceiling height, pillar centers, and obstacle locations (sprinklers, lights, roller doors); (2) Dimensions (L×W×H) and gross weights of your storage bins, cartons, or pallets; (3) Operational method (manual picker access, rolling ladders, or vertical order picker trucks); and (4) Desired target storage capacity and throughput turnover velocity.

Upright columns and horizontal step beams are bundled using high-tensile PET strapping with thick corrugated edge protectors and wrapped in multi-layer stretch film. Steel laminate shelves are stacked on heavy-duty wooden skids with honeycomb board interlays to prevent corner denting. Small hardware (safety locking pins, footplates, expansion bolts) is packaged into labeled wooden crates. All container loading patterns are pre-modeled in 3D to balance weight distribution and protect components against container sweat and sea transit motion.
