China Top Pallet Racking Mezzanine Floor Manufacturer & Suppliers

A structural steel mezzanine relies on heavy hot-rolled H-beam columns and secondary purlins to form a completely free, open floor plan underneath, making it ideal for forklift traffic, heavy production machinery, or modular ground-floor offices. A rack-supported mezzanine utilizes cold-rolled pallet racking or longspan shelving uprights directly as the primary vertical load-bearing columns supporting the mezzanine deck joists. Rack-supported systems cost 25-35% less in raw steel and are the optimal procurement choice when the ground floor is dedicated to palletized storage or manual carton picking.

Every storage system engineered by Guangzhou Heda Shelves is calculated according to European EN 15512:2020 / FEM 10.2.02 and US RMI MH16.1 specifications. We perform static finite element analysis (FEA) on upright punch geometry and claw connector moment-rotation curves. The standard structural safety factor is 1.5 to 1.65 under ultimate dead plus live load. Before dispatch, random batch samples undergo physical load destruction tests to ensure complete structural compliance with ISO 9001:2015 protocol.

To provide an accurate parametric layout and quotation, we require: (1) Warehouse architectural drawings (CAD or PDF) displaying clear internal ceiling height, column grid coordinates, and dock door locations; (2) Pallet dimensions (W x D x H) including goods overhang and gross pallet weight; (3) Forklift specifications, including maximum mast reach height, turning radius, and aisle clearance; (4) Total SKU profile and daily dispatch throughput.

We manufacture four standard mezzanine flooring substrates based on your operation: (1) Perforated / Serrated Steel Grating: Maximize fire sprinkler water penetration (meets NFPA standards) and light transmission; (2) Solid Checkered Steel Plate: Extreme durability for pallet pump trucks and heavy wheeled roll cages; (3) Galvanized Interlocking Slotted Planks: Lightweight, smooth, and cost-effective for retail/foot traffic; (4) High-Density Plywood with Galvanized Underdeck: Superior sound dampening and vibration absorption for office/packing operations.

Our facility utilizes a comprehensive 7-stage chemical surface pretreatment system consisting of high-temperature degreasing, ultrasonic pickling, surface conditioning, and zinc-phosphate immersion wash. Components are then coated on a continuous automated electrostatic line with exterior-grade thermoset epoxy-polyester hybrid powder (60-80μm thickness) cured at 200°C. For sub-zero cold storage or exposed marine dock environments, we provide pre-galvanized or hot-dip galvanized finishes meeting ASTM A123 corrosion resistance.

Yes. Over 80% of our global export orders are installed by local contractor teams. Every shipment includes comprehensive 3D isometric installation drawings, numbered part manifests, anchor bolt torque specifications, and step-by-step video walk-throughs. Our components feature boltless claw connectors and pre-welded upright frames to minimize installation labor. For large-scale projects exceeding 2,000 pallet positions, we can dispatch bilingual on-site site installation supervisors upon request.

Under NFPA 13 and European fire safety regulations, mezzanine floors with a continuous solid area exceeding 2,000 sq.ft generally require dedicated fire sprinkler systems underneath. We solve this by either designing secondary sprinkler pipe hanger brackets directly into our floor joists, or supplying high-transmittance open steel grating (minimum 50% open area) which allows overhead ESFR ceiling sprinklers to protect the ground level without requiring secondary lower pipe runs.

Standard project production turnaround is 15 to 25 calendar days depending on steel volume. Components are packed in ocean-freight knock-down format using heavy timber dunnage, high-tensile PET strapping, corrugated protective corner wraps, and moisture-resistant stretch film. Nested packaging maximizes container stuffing density, ensuring no wasted space inside 20GP or 40HQ ocean shipping units.

Yes. Guangzhou Heda Shelves provides full OEM and ODM capability. If you are extending an existing warehouse installation (e.g., Dexion, Redirack, Stow, or Schaefer standard profiles), our tooling engineering department can stamp matching teardrop, diamond, or hex hole punch patterns and supply identical beam connectors to integrate seamlessly into your current warehouse infrastructure.

We support standard international commercial terms including FOB (Guangzhou/Shenzhen), CFR, CIF (any global port), and DDP (Delivered Duty Paid). Payment methods typically include Telegraphic Transfer (T/T with 30% deposit and 70% against Bill of Lading copy) or Irrevocable Documentary Letter of Credit (L/C at sight) from verified tier-1 global banking institutions.
