Guangzhou HEDA Shelves: 25 Years of Structural Excellence

Founded in 2001, Guangzhou Heda Shelves Co., Ltd. operates a premier 30,000 square-meter production complex equipped with 8 automated continuous cold roll-forming lines, automated robotic welding cells, and an environmental pre-treatment coating plant delivering over 30,000 metric tons monthly.

Structural Integrity, Code Compliance, and Certified Metallurgical Prowess

Selecting a structural mezzanine or heavy-duty racking supplier is a critical structural engineering decision. An under-designed upright profile or poorly engineered baseplate connection can result in catastrophic warehouse failure under dynamic load or seismic excitation. At HEDA Shelves, we employ a dedicated engineering department of over 300 technical personnel and structural draughtsmen who analyze dead loads, live loads, seismic factors, wind shear (for outdoor cantilever installations), and impact resistance coefficients.

Every steel coil entering our plant is subjected to strict yield point, tensile strength, and elongation testing to ensure full compliance with GB/T 700 Q235B and high-yield Q355B standards (equivalent to ASTM A36 and S355JR). Furthermore, our export products possess authentic international verification including CE Certification No. 2435-CPR-8605159 and ISO 9001:2015 Quality Management System No. 18624Q00169R0M. For clients in Australia, New Zealand, and Oceania, our designs strictly reference AS 4084 (Steel Storage Racking) and NZS 1170.5 seismic displacement parameters, providing verified section properties and load calculations for site verification.

Frequently Asked Questions by Industrial Buyers & Importers

Authoritative answers to the most common engineering, compliance, freight, and structural questions posed by international racking contractors and facility managers.

What is the structural difference between a rack-supported and a structural steel mezzanine?

A rack-supported mezzanine utilizes the vertical upright frames and horizontal load beams of heavy-duty pallet racks or long-span shelving as the primary structural support columns for the upper flooring. This is exceptionally cost-effective for multi-tier e-commerce and spare parts pick operations. In contrast, a structural steel mezzanine employs heavy universal steel H-beams, structural square hollow sections (SHS), and cold-formed C/Z purlins to create wide, open-span bays below (spanning 6 to 10+ meters unobstructed) suitable for forklift runways, ground-level machinery, and offices.

How does HEDA Shelves ensure compliance with Australian AS 4084 and NZ seismic standards?

Our engineering team prepares comprehensive static and dynamic calculations based on the structural principles of AS 4084-2023 (Steel Storage Racking) and NZS 1170.5 (Structural Design Actions - Earthquake actions). We provide full structural section properties (moment of inertia Ix/Iy, section modulus Zx/Zy, radius of gyration), connection stiffness test data, and localized load plaque layout drawings. This transparent data package allows your locally registered Chartered Professional Engineer (CPEng / RPEQ) to review and issue local engineering compliance certificates with minimal friction.

What warehouse floor slab criteria are required for heavy-duty pallet rack installation?

Heavy-duty pallet racking and high-density mezzanines transfer substantial concentrated point loads (ranging from 30 kN to over 150 kN per baseplate) into the floor. In general, an industrial concrete slab must have a minimum thickness of 150mm to 200mm, a compressive strength of at least 25 MPa to 32 MPa (C25/30), and appropriate steel reinforcement (SL82 mesh or steel fiber). Floor flatness according to DIN 18202 Table 3 or ASTM E1155 (FF/FL values) is crucial—particularly for VNA (Very Narrow Aisle) truck operations exceeding 9 meters in height.

How do Push-Back Racks compare to Drive-In Racks for cold storage facilities?

In expensive temperature-controlled cold rooms, both systems deliver high volumetric storage density (up to 75% space utilization). However, Push-Back Racks offer significantly higher throughput and worker safety: the forklift operator stays in the main access aisle, pushing pallets onto nested telescoping roller carts on inclined structural channels. In contrast, Drive-In Racks require the forklift driver to physically drive inside the structural bay lanes, increasing the likelihood of upright column collisions and slowing down pallet extraction cycles.

What export packaging protocols are followed to ensure smooth customs clearance?

All export shipments leaving our Guangzhou plant are bundled into heavy-duty welded steel stillages or strapped onto IPPC-certified, heat-treated solid timber pallets bearing clear ISPM-15 inspection stamps. Upright frame bundles are padded with heavy-gauge corrugated edge-protectors and wrapped in waterproof multilayer stretch film to prevent saltwater mist corrosion during long ocean transit. Each container includes comprehensive packing manifests, itemized parts tags, and preferential Certificates of Origin (such as ChAFTA, Form E, or RCEP).

What is the typical production lead time and ocean freight transit window?

Standard factory production for 1 to 5 forty-foot high-cube containers (40HQ) is typically 15 to 22 business days upon final AutoCAD engineering drawing sign-off and color confirmation. Ocean freight transit from South China ports (Nansha, Huangpu, Shenzhen, or Hong Kong) takes approximately 12–16 days to Australian East Coast ports (Sydney, Melbourne, Brisbane), 18–24 days to New Zealand (Auckland, Tauranga), 28–35 days to Western Europe, and 18–25 days to the US West Coast.
