China Wholesale High Density Racking Manufacturers & Factory

Our structural engineering department designs all pallet racking systems strictly utilizing the limit-state calculation principles set out in Australian Standard AS 4084:2023 (Steel Storage Racking), European Standard EN 15512 (FEM 10.2.02), and American RMI MH16.1.

Before fabrication, we furnish comprehensive structural calculation packages detailing upright section modulus, polar moment of inertia, frame stability, and connector shear strengths. These packages allow your local registered structural engineer (or Building Certifier) to independently perform site certification and approve building permits. Standardized safe working load plaques and load warning signs matching national statutory regulations are supplied with every order.

We source raw structural steel coils exclusively from premier domestic state steel producers (such as Baosteel, Shougang, and Ansteel). Primary uprights and critical load-bearing members are manufactured using high-yield Q355B steel (minimum yield strength of 355 MPa, tensile strength up to 510 MPa, comparable to European S355 and ASTM Grade 50). Secondary members, footplates, and spacers utilize certified Q235B steel.

Genuine EN 10204 Type 3.1 Mill Test Certificates are attached to every production heat number, documenting exact chemical composition (carbon, manganese, phosphorus, sulfur) and mechanical elongation/yield parameters.

For projects in high seismic regions (such as New Zealand under NZS 1170.5 or the Western USA under ASCE 7 / IBC), static weight analysis is insufficient. We perform dynamic Response Spectrum Analysis (RSA) based on the specific ground acceleration coefficients ($C_h(T)$) of your facility's postal district.

To resist lateral and longitudinal seismic drift, we engineer:

• Enlarged, ductile baseplates that distribute point forces without shearing slab anchor bolts;
• Dual-anchor anchoring layouts utilizing Hilti or Fischer chemical capsule studs;
• Back-to-back bracing trusses and heavy-duty horizontal plan bracing;
• High-ductility beam end-connectors with 4 to 5 locking teeth to prevent accidental beam dislodgement under cyclic vertical ground shock.

Biosecurity rejections cause catastrophic customs holding fees and demurrage. Heda Shelves eliminates this operational risk at the packing origin. Our factory utilizes 100% certified ISPM-15 compliant heat-treated wood skids (stamped with official IPPC markings) or, preferably, all-steel welded transport stillages.

Steel stillages entirely eliminate timber quarantine protocols at destination ports like Sydney, Melbourne, Auckland, Long Beach, and Rotterdam. Shipping containers are thoroughly swept, clean-air cleared, and desiccant packs are placed throughout to prevent mold formation during humid equatorial sea transit.

Standard production cycles for typical high-density warehousing projects (5 to 20 forty-foot high-cube containers) require approximately 20 to 28 calendar days from finalized 3D CAD approval.

Transit lead times from our Guangzhou / Nansha or Shenzhen ports to major global destinations typically average:

• Australia / New Zealand (Sydney, Melbourne, Auckland): 14 to 22 days;
• US West Coast (Los Angeles / Long Beach): 16 to 22 days;
• Europe (Rotterdam, Hamburg, Felixstowe): 28 to 35 days;
• Southeast Asia (Singapore, Port Klang, Jakarta): 5 to 10 days.

Yes. Guangzhou Heda Shelves Co., Ltd. serves as an OEM/ODM manufacturing backbone for dozens of prominent material handling equipment dealers worldwide. We provide custom tool profiling for proprietary beam connectors, match corporate RAL color powder codes, and laser-cut your brand's trademark into safety upright protectors, row spacers, and packaging labels. Complete confidentiality agreements (NDAs) are routinely executed.

To produce an accurate structural design proposal and competitive pricing estimate within 24 hours, our engineering department requires:

• Building Architectural Drawing: Length, width, building clear height under truss, column grid spacing, access docks, and fire exit locations;
• Pallet Characteristics: Dimensions (W × D × H including cargo overhang) and maximum gross pallet load weight;
• Material Handling Equipment: Forklift make, model, mast collapsed height, maximum lift height, and minimum right-angle stacking aisle requirement (AST);
• Operational Environment: Ambient temperature or cold storage (°C), daily throughput SKU volume, and seismic/coastal geographic location.
