Top Trusted Industrial Shelving Racks Equipment Supplier & Suppliers

To provide an engineered, compliant CAD layout and structural load certificate, our design team requires: (1) An architectural CAD drawing or accurately dimensioned floor plan illustrating building column centers, perimeter walls, structural expansion joints, and ingress/egress bay doors; (2) Building clear height to the lowest hanging overhead obstruction (sprinkler mains, HVAC ducting, or purlin roof trusses); (3) Pallet specifications including overall dimensions (length, depth, loaded height) and gross unit weight per pallet; (4) Operating material handling equipment specifications (forklift model, minimum turning radius, outer mast collapse height, and maximum mast lift reach); and (5) Local regulatory requirements such as regional seismic acceleration factors and sprinkler flue gap dimensions.

HEDA manufactures upright frames and load-bearing step/box beams using structural certified steel grades Q235B and high-tensile Q355B (equivalent to ASTM A36 and ASTM A572 Grade 50). All profile geometries are cold-formed in our ISO 9001:2015 certified production lines and structural designs strictly adhere to European standard EN 15512 (Steel static storage systems), RMI ANSI MH16.1 (Specification for Industrial Steel Storage Racks), and Australian AS 4084 regulations. Certified mill test certificates (MTC) documenting chemical composition and tensile elongation are delivered with every container shipping pack.

Corrosion prevention starts with mechanical steel pre-treatment. Components undergo multi-stage ultrasonic chemical degreasing, acid pickling, and iron phosphating conversion treatments that establish a microscopic protective anchor layer on the raw steel. Components then enter an automated electrostatic booth receiving thermosetting epoxy-polyester powder applied to a minimum 60–80 micron film thickness, baked at 180°C–200°C. For extreme atmospheric exposure—such as walk-in cold rooms down to -30°C, outdoor coastal lumber yards, or corrosive fertilizer storage—we provide heavy-duty hot-dip galvanization (HDG) in full accordance with ISO 1461, providing a 70–100 micron zinc alloy barrier ensuring 25+ years of rust-free service life.

In accordance with international storage standards (FEM 10.2.02 and RMI MH16.1), the maximum permissible vertical deflection of a horizontal racking beam under a uniformly distributed load (UDL) must not exceed L/200, where L represents the clear span of the beam between upright column faces. For automated ASRS or high-bay narrow aisle systems, HEDA tightens this deflection tolerance to L/250 or L/300 to prevent automated shuttle misalignment or robotic sensor collision during high-speed retrieval cycles.

Yes. For installations in active seismic zones (such as Japan, the Philippines, Indonesia, New Zealand, Turkey, and western South America), our structural engineering team conducts dynamic seismic spectral response analyses. We reinforce baseplate thicknesses up to 12mm–16mm, specify high-grade expansion anchors or chemical anchor studs, and design heavy X-bracing and top-tie spine structures that effectively absorb ground acceleration shears, preserving overall warehouse structural stability during earthquake events.

Standard production lead times range between 15 to 25 calendar days depending on tonnage and custom color coatings. We provide expert container stowage plans, strapping long upright columns on specialized protective steel skids and nesting beam packs with heavy-gauge corrugated dunnage and waterproof bubble wrap. Every shipment leaves South China ports (Guangzhou / Shenzhen / Foshan) accompanied by clear packing lists, component coding tags, and detailed 3D step-by-step assembly diagrams for frictionless on-site contractor installation.
