Engineered specifically for intermediate-to-heavy manual loading requirements, bridging the mechanical performance gap between lightweight commercial boltless shelving and heavy structural pallet racking.
Top SellerEngineered with 55×47mm cold-formed upright profiles and heavy step beams. Accommodates flush drop-in steel panels for chemical and retail distribution.
Streamlined P-beam and tube-step construction tailored for medium packaging, e-commerce order picking, and hardware storage.
Equipped with flanged zinc-electroplated wire mesh decks. Meets international NFPA fire safety sprinkler standards by allowing uninhibited water cascade.
Multi-TierConverts vertical warehouse cube into multi-floor manual picking platforms. Uprights act as structural load columns supporting catwalks and overhead stairs.
Purchasing managers and logistics facility engineers frequently miscalculate the difference between nominal uniform distributed loads (UDL) and concentrated dynamic point loads. Standard light-gauge shelving frequently undergoes beam deflection failure or post-buckling when subjected to uneven carton distribution.
Guangzhou Heda Shelves Co., Ltd. builds every longspan frame using structural cold-rolled steel (grade Q235B / SS400). Uprights feature continuous cold-roll forming with proprietary butterfly or teardrop hole punch patterns, offering unyielding tensile resistance and 50mm vertical shelf adjustability.
Our dual-flange step beams interlock into upright columns through heavy three-prong steel connector claws secured with high-visibility zinc safety locking pins. This mechanical engagement prevents accidental beam dislodgement under rough manual impact or cart collisions.
Engineered under European FEM 10.2.06 and EN 15512 codes, ensuring strict elastic deflection limits under maximum nominal payload.
Comprehensive 8-stage pickling and phosphating wash cycle prior to coating, preventing under-film rust even in humid coastal facilities.
Every beam tier includes integrated under-deck cross supports, preventing beam rotation and eliminating panel sag under heavy cartons.
Heavy-duty stamped baseplates with twin chemical M10/M12 anchor slots to distribute axial column loads safely into building floor slabs.
How autonomous mobile robots, micro-fulfillment centers, and omni-channel retail are reshaping global demand for wide-span shelving infrastructures.
01Next-generation warehouses combine manual longspan pick faces with Autonomous Mobile Robots (AMRs). Shelving designs require ultra-consistent clear bottom clearances, QR-code fiducial mounting strips, and high-tolerance beam levels to permit seamless collaborative human-robot picking workflows.
02With warehouse real-estate costs climbing, logistics managers are turning small-footprint urban facilities into high-density fulfillment hubs. Multi-tier longspan configurations utilize 100% of clear roof heights, tripling picking locations without incurring commercial building expansion costs.
03Supply chains must adapt to seasonal inventory volatility. Boltless quick-connect longspan designs enable on-site warehouse teams to adjust beam levels in minutes without specialized welding or hydraulic tools, avoiding costly operational downtime during product line changeovers.
04Corporate ESG procurement mandates demand traceable, low-emission cold-rolled steel and zero-VOC powder finishes. Guangzhou Heda Shelves Co., Ltd. incorporates RoHS-compliant thermoset epoxy powders and energy-optimized roll-forming lines to satisfy international green building standards.
For more than two decades, Guangzhou Heda Shelves Co., Ltd. has stood at the forefront of industrial warehousing engineering. Operating from our advanced 30,000 square meter manufacturing base in Guangzhou, China, our integrated operation covers precision steel slitting, automated CNC cold roll-forming, robotic welding, and high-volume powder coating lines.
With an engineering team exceeding 300 technical specialists, we provide direct end-to-end project management. From initial architectural AutoCAD layouts and finite element analysis (FEA) to container export packaging and field installation guice, we ensure zero engineering discrepancies upon project delivery.
Configured across diverse global industries where high SKU variety and high-density manual access are paramount.
From brake discs and exhaust headers to filters, sensors, and electrical components, our heavy-duty longspan shelving provides adjustable shelf levels with dividers and plastic bins for rapid SKU identification.
Optimized for high-velocity carton picking. Multi-level longspan shelving reduces worker transit time by concentrating picking faces within dense, ergonomic zones.
Engineered for machine tool storage, raw material tubs, and tooling dies. Our heavy step-beams and steel panel decks support up to 1,000 kg per shelf tier safely.
Designed for sterile, moisture-prone, or regulated storage environments where cleanability, hygiene, and corrosion resistance are mandatory for regulatory certification.
Guangzhou Heda Shelves Co., Ltd. controls every metallurgical and finishing phase in-house to ensure strict dimensional tolerances and safety compliance.

In-depth technical answers addressing the critical load calculation, installation, fire safety, and logistics questions asked by enterprise procurement buyers and warehouse planners.
Contact UsGuangzhou Heda Shelves Co., Ltd. manufactures industrial longspan systems rated from 300 kg to 1,000 kg (660 lbs to 2,200 lbs) Uniformly Distributed Load (UDL) per shelf level. The actual structural capacity is determined by the combination of upright profile thickness (1.5mm to 2.0mm Q235B steel), beam section geometry (step beam depth from 50mm to 80mm), clear span length (1,200mm to 2,700mm), and the quantity of underlying deck reinforcement ties. Every engineered project is delivered with formal load warning plaques and calculation sheets.
Industrial longspan shelving occupies the critical operational middle ground. Standard light-duty shelving is designed for light office or commercial stock under 150 kg per level, often utilizing thin sheet-metal posts. Heavy pallet racking is optimized for forklift pallet handling, with frame depths and beams too deep and wide for ergonomic manual hand picking. Longspan shelving delivers unobstructed, wide-span shelf openings (up to 2.7m wide) designed specifically for hand-loaded boxes, oversized machinery spares, and multi-tier manual pick towers without requiring forklifts inside the picking aisle.
The optimal decking selection depends on operational environment and local building codes. Solid steel decking panels (galvanized or epoxy powder-coated) provide maximum load rigidity, long service life, chemical resistance, and ease of sanitation. Open wire mesh decking is strongly recommended for facilities with overhead fire sprinkler systems, as it allows water penetration complying with NFPA standards while eliminating dust settling. High-density particleboard or marine plywood is an economical alternative for dry parts storage, though it is vulnerable to high humidity and water absorption.
Yes. Guangzhou Heda Shelves Co., Ltd. specializes in shelving-supported mezzanine platforms. In these multi-tier structures, heavy-gauge longspan uprights extend continuously upwards through 2 to 4 vertical picking levels. Heavy-duty bearer beams clamp directly to the upright frames to support steel grating, bar grating, or plywood walkways, incorporating staircases, handrails, pallet gates, and conveyor chutes to triple warehouse cube utilization without structural building modifications.
For single-run longspan shelving exceeding a height-to-depth ratio of 5:1, mechanical anchoring into reinforced concrete slabs (minimum compressive strength 20-25 MPa) is mandatory. We provide heavy stamped steel baseplates with pre-punched expansion bolt holes, allowing floor bolting using M10 or M12 wedge anchors. In active seismic zones or high-bay manual pick towers, top cross-bracing ties, back cross-bracing diagonals, and frame-to-wall ties are incorporated to counter horizontal seismic shear forces.
Guangzhou Heda Shelves Co., Ltd. operates in full compliance with ISO 9001:2015 quality management standards (Certificate No. 18624Q00169R0M) and holds verified CE conformity certification (No. 2435-CPR-8605159). Our powder coatings conform to RoHS environmental guidelines. We provide a comprehensive factory structural warranty against raw material defects and weld fractures under design loading conditions.
