China Best Pallet Storage System Manufacturer & Factories

We exclusively utilize certified prime cold-rolled coils of Q235B (yield strength $\ge 235 \text{ MPa}$) and high-tensile Q355B (yield strength $\ge 355 \text{ MPa}$, equivalent to European S355JR or ASTM A572 Grade 50). Every steel delivery arrives with certified Mill Test Certificates (MTC) detailing chemical composition (carbon, manganese, phosphorus, sulfur) and mechanical tensile elongation values. This guarantees structural ductility and eliminates catastrophic brittle-fracture hazards under cyclic warehouse loading.

Our structural racking is designed and load-tested in strict compliance with European standard EN 15512 (Steel static storage systems – Adjustable pallet racking systems – Principles for structural design), EN 15620 (Tolerances, deformations and clearances), FEM 10.2.02, American RMI MH16.1 (Specification for the Design, Testing and Utilization of Industrial Steel Storage Racks), and Australian AS 4084-2023. We hold official CE factory production control certification (No. 2435-CPR-8605159) and ISO 9001:2015 registration.

Our automated surface finishing line performs continuous 9-stage chemical pretreatment, including high-temperature alkaline degreasing, clean-water rinsing, hydrochloric acid pickling to eliminate scale, and dual zinc phosphating. We then apply an electrostatic thermoset epoxy-polyester powder coating cured at 180°C–200°C. This delivers an impermeable 60–80 μm dry film thickness with a cross-hatch adhesion rating of ASTM D3359 Class 5B and corrosion resistance exceeding 500 continuous hours in ASTM B117 salt spray tests. For extreme outdoor yards, hot-dip galvanizing per ASTM A123 is available.

For standard selective pallet racks up to 8 meters with 1,000–2,000 kg pallets, the industrial concrete floor slab should provide a minimum compressive strength of 25–30 MPa (C25/C30), a minimum slab thickness of 150–200mm, and an F-Number flatness rating of FF 25 / FL 20 or higher. For Very Narrow Aisle (VNA) or high-bay AS/RS structures over 12 meters, a superflat concrete slab compliant with DIN 18202 Table 3 Group 4 or TR34 DM2 standards is essential to prevent mast sway and beam collisions.

We use customized mathematical load-planning software to maximize both container weight and cube space without exceeding port limits (typically 25–26 metric tons per 40HQ). Uprights and beams are bundled using high-tensile steel banding, fitted with heavy-duty corner-edge protectors, and shrink-wrapped in waterproof VCI plastic film. Wooden dunnage runners are bolted beneath bundles to allow smooth forklift unloading at your destination facility without scratching powder coatings or bending connector pins.

Yes. We provide complete structural engineering calculation dossiers, Finite Element Analysis (FEA) deflection diagrams, and dimensional 2D CAD architectural plans clearly designating aisle clearances, egress routes, longitudinal flue spaces, and in-rack sprinkler pipe elevations. These detailed packages meet the rigorous review standards required by local municipal building inspectors, Civil Defense departments, and international property underwriters such as FM Global.
