China Wholesale Storage Racking Manufacturers & Manufacturer

Every production batch shipped from Guangzhou Heda Shelves is accompanied by an official Mill Test Certificate (MTC) conforming to EN 10204 Type 3.1. We supply certified Q235B and Q355B cold-rolled structural steel coils sourced directly from top-tier primary domestic mills (such as Baosteel and Shougang). The chemical analysis explicitly outlines carbon, manganese, phosphorus, and sulfur content alongside mechanical yield strength (≥235 MPa or ≥355 MPa), ultimate tensile capacity, and Charpy impact energy ratings. Independent SGS or TÜV third-party lab inspection before container stuffing is welcomed upon buyer request.

For seismic installations across Southeast Asia, Japan, Central America, or the Middle East, our design engineering team conducts dynamic modal analysis based on local seismic ground acceleration spectra. We modify frame geometry by enlarging footplate surface areas, transitioning to 120mm–140mm wide upright profiles with heavier gauges (2.5mm to 3.2mm), upgrading to heavy-duty wedge anchoring bolts, and engineering double-braced diagonal X-frames. Complete structural engineering calculation reports and beam deflection stress plots are provided in CAD and PDF formats for submission to municipal civil defense and planning authorities.

Standard warehouse components pass through an automated 9-stage pre-treatment line featuring hot-alkaline degreasing, rust-stripping pickling, and micro-crystalline zinc phosphating before receiving a 60–80 micron electrostatic epoxy-polyester powder coat baked at 180°C–200°C. For deep-freeze environments (-25°C to -35°C), high-humidity equatorial zones (Vietnam, Malaysia, Indonesia), or coastal open-yard cantilever racks, HEDA supplies hot-dip galvanized (HDG) steel components conforming to ISO 1461 / ASTM A123 with a minimum 65–85 micron zinc layer that delivers over 20 years of maintenance-free service.

Because storage racking is dense, structural steel orders typically hit container weight limits (26–28 tons in 40ft HQ or 20ft GP containers) before cube volume is exhausted. Our logistics department utilizes 3D container packing software to engineer customized nesting schemes. Upright frames are stacked with custom corrugated interleaving and timber blocks to prevent flange deformation. Beams are bundled with high-tensile steel strapping and protected by heavy-duty cardboard edge protectors. Boxed hardware, safety locks, and column protectors are positioned at container doors to permit swift unloading via forklift slip-sheet or counter-weighted boom.

To generate an optimized warehouse layout drawing with exact pallet position calculations, please provide:
1. Architectural floor plan (AutoCAD DWG or dimensioned drawing) showing column grid locations, egress doors, dock levelers, and clear ceiling heights beneath fire sprinklers.
2. Pallet specifications: Width, depth, load height including pallet base, and maximum gross pallet weight.
3. Material handling equipment (MHE): Forklift turning radius, mast lift height, and minimum aisle width requirements.
4. SKU distribution logic: Number of unique product lines, throughput turnover, and inventory management preferences (FIFO vs. LIFO).

Guangzhou Heda Shelves Co., Ltd. holds verified CE Certification (No. 2435-CPR-8605159) demonstrating compliance with Construction Products Regulation (CPR) harmonized standards, ISO 9001:2015 Quality Management Certification (No. 18624Q00169R0M), and certified RoHS conformity for all applied powder coating pigments. We manufacture in compliance with European Storage Racking Standard EN 15512 and FEM 10.2.02 codes.
