Mezzanine Platform Racking Systems
Integrates heavy-duty shelf racking or pallet frames with suspended structural walkways, enabling efficient multi-tier manual order fulfillment.
Engineered by PrimeBay Heavy Duty Racking Co., Ltd. to double or triple usable warehouse floor space within existing building footprints across global industrial markets.
PrimeBay Heavy Duty Racking Co., Ltd. is a certified manufacturer specializing in structural steel mezzanine floors, rack-supported platforms, and multi-tier racking systems. By turning unused vertical clearance into multi-level picking areas, office floors, or pallet storage decks, our engineered solutions eliminate the huge capital expense of facility relocation or brick-and-mortar building expansion.
Every mezzanine project is designed according to strictly audited structural calculations, structural grade steel profiles (Q235B / Q355B), and international safety codes. From CAD layout engineering and automated production to complete export packing, PrimeBay provides end-to-end reliability for international distributors, general contractors, and warehouse operators.
Explore our main structural configurations engineered for heavy-duty warehouse storage and high-throughput order picking.

Integrates heavy-duty shelf racking or pallet frames with suspended structural walkways, enabling efficient multi-tier manual order fulfillment.

Multi-level storage structures utilizing high-bay vertical air space with integrated staircases, safety handrails, and pallet drop gates.

Heavy-duty rack structures engineered for automotive parts distribution, spare parts hubs, and high-density industrial storage warehouses.

High-density racking combined with steel grating or wood deck walkways, optimizing bin picking productivity for e-commerce operators.

Heavy-gauge structural steel deck platforms created to convert empty upper warehouse space into work decks or storage balconies.

Freestanding structural column and beam platforms built for heavy machinery support, packing zones, or elevated office areas.
Select the ideal structural framework based on your building clearance, floor load capacity, and material handling workflow.
Uses heavy-duty pallet racking frames or shelving uprights as the primary load-bearing columns supporting upper steel walkway decks. This hybrid design delivers simultaneous high-density bin picking on upper levels and palletized unit storage below, maximizing ROI per square meter.
Freestanding steel structures engineered with primary steel columns (H-beams / square tubes) and secondary steel joists. Provides wide column spans below, creating unobstructed open floor space for forklift maneuvering, assembly lines, or packing operations.
Architectural multi-deck configurations (2 to 5 levels) engineered for tall fulfillment centers. Features modular stairways, goods lifts, chute integrations, and peripheral perimeter safety handrail networks for safe high-rise picking.
Custom heavy-load platforms engineered to accommodate light machinery, sorting conveyors, or modular office cabins on upper levels while preserving primary warehouse operations underneath.
PrimeBay manufactures all structural components in-house using premium cold-rolled and hot-rolled structural steel profiles.
