Precision-manufactured cold-rolled Q235B/Q355B structural steel systems engineered to EN 15512, RMI ANSI MH16.1, and AS 4084 standards. Select standard dimensions or request fully custom OEM/ODM roll-forming.
Engineered for heavy bulk pallet loads up to 4,000 kg per beam level with thermoset epoxy-polyester electrostatic coating.
Continuous 50mm and 75mm pitch upright pitch for modular vertical spacing, factory buffer zones, and heavy component storage.
Ultra-hygienic, anti-corrosive stainless steel tier shelving for food cold chains, cleanrooms, and pharmaceutical storage.
Fully customizable column gauges, interlocking beam connector claws, safety locking pins, and seismic-rated baseplates.
Continuous dynamic gravity roller track for strict First-In, First-Out batch rotation, zero-power operation, and high throughput.
Demountable post frames allowing flexible 4-tier vertical stacking without permanent anchoring; optimal for rented facilities.
North American teardrop compatibility profile with 2-inch increments, toolless pin locking, and reinforced tubular bracing.
Universal selective industrial storage rack featuring high load safety factors, compatible with counterbalanced and reach trucks.
In structural warehousing, load-bearing reliability is governed by cold-work hardening, precise profile moment of inertia ($I_x, I_y$), and compliance with international structural racking codes.
We source prime certified Q235B and Q355B structural coil (equivalent to ASTM A36 and ASTM A572 Grade 50). Minimum guaranteed yield strength ($f_y$) spans from 235 MPa to 355 MPa, delivering superior elastic-plastic deformation behavior during dynamic seismic impacts or accidental forklift contact.
Every horizontal box beam and step beam profile is manufactured to conform with EN 15512 and RMI MH16.1 specifications. Under maximum static safe working load (SWL), maximum vertical beam deflection never exceeds $L/200$ (or $L/300$ for automated AS/RS interfaces), eliminating weld fatigue and dislodgement hazards.
Prior to coating, steel components undergo immersion chemical pickling, degreasing, and zinc phosphating. Electrostatic thermoset epoxy-polyester powder is cured at 180°C–200°C, producing a dense 60–90 μm polymer film that resists ASTM B117 neutral salt spray tests exceeding 500 hours without blistering.
Operating since 2001, Guangzhou Heda Shelves Co., Ltd. controls the complete supply chain from coil decoiling and continuous roll forming to certified container export consolidation.
Our in-house structural engineers utilize AutoCAD, SolidWorks, and 3ds Max to model custom warehouse layouts, clear height aisle configurations, and seismic load distributions, delivering complete 2D layout drawings and 3D renderings within 24 hours of specification receipt.
Certified under European CE Directives (Certificate No. 2435-CPR-8605159) and ISO 9001:2015 Quality Management Systems (Registration No. 18624Q00169R0M, valid through June 2027), with verified RoHS compliance across all surface coatings and non-toxic powder treatments.
Custom knock-down packaging engineered specifically for 20GP, 40GP, and 40HQ sea freight containers. Profile nesting algorithms minimize cubic waste, reducing ocean freight costs per pallet position while bundled protective corner guards eliminate transit abrasion.

Technological shifts, supply chain resilience, and environmental metrics are transforming how enterprise supply chain directors procure industrial storage systems.
Modern warehouse shelving is transitioning from passive static steel structures to active autonomous robotics interfaces. OEM manufacturing must now meet tight structural tolerances (±1.5mm upright plumbness) to facilitate laser guidance reflectors, optical floor markers, and autonomous mobile robot (AMR) under-chassis clearance beneath low-profile base tiers.
Surging global demand for temperature-controlled pharmaceuticals and perishables requires specialized steel behavior at sub-zero thresholds (-30°C). Cold rooms induce brittle ductile-to-brittle transitions in common mild steel; modern procurement mandates high-impact Charpy-V-notch tested steel grades and hot-dip galvanized components resistant to heavy thermal condensation cycles.
E-commerce SKU churn has rendered rigid, single-purpose installations obsolete. Procurement heads now favor hybrid systems: selective pallet bases with integrated carton flow pick tracks and modular boltless teardrop uprights that allow level changes by warehouse personnel without requiring hot-work permits or welding.
Major enterprise tenders increasingly evaluate embodied carbon footprints in warehouse infrastructure. HEDA Shelves utilizes scrap-recycled electric arc furnace (EAF) coil inputs and heavy metal-free TGIC-free polyester powder coatings, providing transparent mill test certs (MTC) and environmental verification documents for LEED and BREEAM industrial facility accreditations.
Direct answers from our structural manufacturing team on tolerances, international compliance, finish specifications, and logistics delivery.
Both specifications define limit state engineering calculations for cold-formed thin-walled steel members. European EN 15512 mandates specific partial load factors for seismic and dead loads, requiring finite element analysis (FEA) of perforated upright stability. ANSI MH16.1 (RMI) standardizes connection looseness tests, beam-to-column connector moment capacity, and column baseplate floor anchoring shear requirements.
Powder coating offers a cost-effective, scratch-resistant finish for controlled indoor environments with 60–90 μm thickness across standard RAL colors. Hot-dip galvanizing (HDG according to ISO 1461) immerses bare steel into molten zinc at 450°C, producing a metallurgically bonded zinc-iron alloy layer (minimum 65–85 μm) that delivers self-healing anodic protection against marine humidity, fertilizers, and sub-zero condensation.
Yes. Through our OEM/ODM tooling workshop, we manufacture proprietary upright hole geometries including standard 75mm European pitch, 50mm diamond patterns, and 2-inch teardrop profiles. We develop custom stamping dies to match your existing racking profile inventories for seamless project expansions.
We require: 1) Architectural building CAD file showing column grids, overhead obstructions, and egress points; 2) Pallet specifications including overall dimensions (W×D×H), maximum gross load, and overhang allowance; 3) Material handling equipment (forklift turning radius, mast lowered/raised height); and 4) Seismic zone classification and floor slab concrete strength rating ($f'_c \ge 25 \text{ MPa}$).
Beams and upright frames are nested in structural steel packaging jigs wrapped in multilayer bubble poly-sheeting with corner edge guards. Heavy accessories (baseplates, row spacers, bolts) are packed in fumigated plywood crates or strapped steel pallets, eliminating container shifting and metal-on-metal salt air chafing.
Standard selective pallet racking systems ship within 14–20 days from technical drawing confirmation. Custom tooling profiles, heavy structural mezzanine platforms, or automated radio shuttle lines require 25–35 days to allow full roll-forming calibration, pickling, powder baking, and pre-shipment trial assembly inspection.
