Precision Engineering, High-Density Storage Design, and Global Turnkey B2B Supply Chain Manufacturing
Custom structural engineering for demanding warehouse configurations, intralogistics consolidation, and heavy-duty load distribution.
Operating over 30,000 square meters of precision fabrication capacity with complete ISO 9001:2015 and CE certification standards.
Our continuous automated roll-forming lines process structural carbon steel (Q235B/Q355B) with millimeter tolerances, maintaining continuous yield strength along uprights and step beams under critical loading.
Every longspan shelving and high-bay racking system is engineered with proprietary FEA software to model seismic load vectors, localized buckling coefficients, and elastic deflection limits aligned with EN 15512 and RMI standards.
Pre-treatment involves automated multi-stage chemical degreasing, ultrasonic phosphating, and heavy electrostatic thermoset polyester powder coating, certified under RoHS and CE No. 2435-CPR-8605159.
A comprehensive engineering review of next-generation intralogistics specifications, material efficiency, and global distributor dynamics.
The traditional divide between manual pick longspan shelving and autonomous mobile robotics (AMR) is rapidly disappearing. Enterprise facilities are transitioning toward hybrid fulfillment hubs where modular longspan structures interface directly with Autonomous Case-handling Robots (ACR) and collaborative pick-assist bots.
Raw steel volatility and international carbon accounting standards are pushing industrial manufacturers toward higher tensile strengths (e.g., transitioning from standard Q235B to micro-alloyed Q355B). This shift reduces total component deadweight while preserving ultimate load-bearing capacities.
Tier-1 supply chain contractors are steering away from closed, proprietary upright slot profiles. Sourcing demands focus heavily on open-architecture slotted configurations (50mm/75mm adjustable pitch systems) that allow seamless cross-compatibility between beam brackets, steel decking, wire mesh inserts, and modular chipboard panels.
Essential answers for supply chain managers, warehouse operations leads, and industrial procurement professionals.
While standard pallet racking is engineered explicitly for unitized pallet handling via counterbalance or reach forklifts (typically bearing 1,000kg to 4,000kg per level), Longspan Shelving is structurally optimized for manual piece-picking, tote storage, and intermediate industrial loads (typically 300kg to 1,000kg per level). Longspan uses specialized step beams matched with drop-in steel, wire mesh, or timber decking, utilizing lighter, highly adjustable upright gauges with narrower beam depths to optimize internal cubic pick volume.
Load calculation follows structural design guidelines set forth by EN 15512:2020 and RMI (Rack Manufacturers Institute). We assess: 1) Uniformly Distributed Loads (UDL), 2) Beam elastic deflection limits (traditionally capped at L/200, or span length divided by 200), and 3) Upright frame compression capacity factoring in vertical beam spacing (the unsupported bucking length). Every OEM/ODM project includes full structural calculation sheets verifying safety factor coefficients of at least 1.5 to 1.65.
Yes. We routinely export to active seismic regions across Central America, Southeast Asia, and the Pacific Rim. By integrating your site-specific seismic ground acceleration data (Ss, S1 parameters), floor slab compressive strength ratings, and warehouse anchor configurations, our engineering department designs heavy-duty seismic base plates, heavy structural bracing diagonals, and expanded-anchor tie systems to prevent structural resonance and frame overturning.
For standard humidity-controlled conditions, our 60–80 micron electrostatic polyester powder coating delivers exceptional abrasion resistance. However, for port-adjacent operations, tropical maritime humidity, or chemical distribution, we offer hot-dip galvanization (HDG) to EN ISO 1461 standards, or enhanced dual-coat zinc-epoxy powder formulations that pass 500-hour neutral salt spray tests without blister formation.
All upright columns and roll-formed box/step beams are punched and roll-formed on continuous computer-controlled servo lines, preserving ±0.5mm hole center tolerances for boltless locking connectors. For overseas shipping, components are nested, strapped on heavy timber dunnage with corner edge guards, and indexed against computer-modeled container packing schedules, ensuring container cube utilization exceeds 90% without component distortion.
