China Wholesale Pallet Rack Storage Solutions Manufacturer & Exporter

We procure prime cold-rolled steel coils strictly from Tier-1 state-owned metallurgical mills (such as Baosteel, Shougang, and Ansteel). Every coil delivery arrives with official Mill Test Certificates (MTC) detailing chemical composition (carbon, manganese, phosphorus, silicon) and physical mechanical yields. Before slitting and roll-forming, our QA laboratory conducts destructive tensile testing and spectrometer checks to ensure steel conforms rigidly to Q235B (yield strength ≥ 235 MPa) or Q355B (yield strength ≥ 355 MPa, comparable to European S355 and ASTM A572 Grade 50).

Yes. Our structural design group utilizes specialized cold-formed finite element analysis (FEA) software capable of generating calculation dossiers under ANSI/RMI MH16.1-2021 (USA), CSA-A344 (Canada), EN 15512:2020 (Europe), and AS 4084:2023 (Australia). We supply complete sectional modulus tables, baseplate anchoring shear/uplift calculations, and beam-to-column connector torsional spring stiffness (kinematics) test data. This engineering documentation allows your local Licensed Professional Engineer (PE) or Structural Engineer (SE) to stamp calculations for building permit approval without delay.

Ocean container freight optimization is critical to landed project profitability. We bundle upright posts in nested configurations with protective non-marking separators to eliminate transit rub and paint abrasion. Beams are palletized in high-density, steel-strapped bundles with heavy wood dunnage base runners. Accessories (baseplates, row spacers, shims, beam safety clips, anchor bolts) are packed in reinforced, palletized wooden crates. Every 40ft High Cube container is weight-maximized (typically up to 26–28 metric tons depending on port and state road-weight limits) using 3D loading software to ensure 98%+ volumetric and mass efficiency.

Yes. We manufacture standard North American universal teardrop punching patterns on 2-inch vertical increments. Our upright columns and 3-rivet / 4-rivet step beam connectors assemble interchangeably with dominant North American brands such as Interlake Mecalux, Ridg-U-Rak, SpaceRak, and Speedrack. For distributor and OEM brand clients, we also fabricate proprietary hole geometries, including European diamond patterns, 75mm British box profiles, and 50mm metric configurations.

Standard production turnaround for a 5-to-10 container order is approximately 20 to 25 business days from structural drawing approval and deposit receipt. Expedited schedules can be coordinated through our 14 parallel roll-forming lines. For continuous enterprise replenishment contracts, we can maintain raw steel reserves and pre-slit mother coils, shortening production turnaround on repeat standard modules down to 10–14 business days.

Sub-zero cold storage facilities (operating between -20°C and -35°C) cause standard structural carbon steel to undergo ductile-to-brittle transitions. For freezer applications, we specify Charpy V-notch impact-tested Q355D/E steel grades to prevent brittle fracture under low temperatures. Furthermore, we apply specialized low-temperature flexible epoxy-polyester hybrid powder coats or specify Continuous Hot-Dip Galvanizing (HDG conforming to ASTM A123 / ISO 1461) to eliminate condensation pitting and structural flaking under continuous freeze-thaw condensation cycles.
