A premier manufacturer and structural design partner specializing in intelligent warehouse storage systems and heavy-duty steel shelving.
Established in 2016, Dongguan Hui Lian Intelligent Warehouse Equipment Co., Ltd. has developed deep engineering and manufacturing capabilities in the intelligent logistics and physical material handling sectors. Integrating raw material cold rolling, structural optimization, robotic automated welding, and high-quality electrostatic powder coating, we configure high-performance logistics storage architectures. Operating from a fully-equipped 18,500 square meter plant, we support heavy-duty racking systems, customized industrial mezzanine floors, cantilever systems, automated warehouse racking, and robust, adjustable boltless systems for commercial, industrial, and consumer markets.
Backed by 8 years of dedicated export experience, our engineering and sales teams maintain full alignment with international cargo storage codes, regional structural safety standards, and strict supply chain execution protocols. From initial layout design using CAD/SolidWorks to on-site installation coordination, we deliver reliable solutions tailored to help clients optimize warehouse capacity, improve inventory turnover, and ensure operational safety.
Precision engineering combined with automated manufacturing to guarantee structural integrity, tight dimensional tolerances, and stable production capacity.
Our factory processes high-strength steel using automated machinery to ensure every rack component meets specified dimensional tolerances and load profiles. We run several advanced production lines, including roll-formers, automated welders, and powder-coating systems, ensuring consistent production speed and structural quality.

Industrial storage rack safety is based on calculations that ensure structures support weight without failure under long-term stresses. According to European design standards (such as EN 15512) and the US Rack Manufacturers Institute (RMI) specification, structural beam deflection must remain within set limits: Deflection (δ) ≤ L / 200 (where L is the clear span of the horizontal beam).
For heavy pallet loads, we also calculate seismic forces, column baseplate pressure distribution, and upright frame buckling limits under critical loads. The buckling critical load of our structural steel columns is calculated using Euler's formula modified for thin-walled cold-formed steel sections:
P_cr = (π² * E * I_eff) / (K * L)²
Where E is the modulus of elasticity of steel (2.05 × 10⁵ N/mm²), I_eff is the effective moment of inertia of the perforated upright section, K represents the effective length factor based on bracing configuration, and L is the unsupported column height.
Customized storage configurations engineered for safety, speed, and efficiency across diverse industrial sectors.
Designed for fast-moving SKU handling, combining medium-duty shelving, pick-to-light support, and flow-racks. We reduce worker travel times by organizing items in multi-level mezzanine configurations that make full use of building height.
Designed to support concentrated, heavy loads from metal dies, heavy components, and machine parts. These racks feature thick-walled steel frames and optional deck supports, offering load capacities exceeding 3,000 kg per level.
Optimized for cold storage facilities where space is expensive. Our structural steel members use low-temperature rated alloys (such as Q355D steel) and corrosion-resistant powder coatings to prevent rust and maintain structural integrity below freezing.
Our product development roadmap focuses on integrating structural steel components with automated, digital warehouse systems.
Modern AS/RS (Automated Storage and Retrieval Systems) demand tight vertical straightness tolerances. We manufacture uprights with deviation limits of less than 1 in 1000, ensuring automated crane shuttles and AGVs move smoothly without collisions.
We are testing smart load sensors integrated directly into pallet beam connectors. These sensors warn warehouse managers of weight overloads, structural shifting, or impact damage via real-time dashboard notifications.
Working to reduce the environmental footprint of our products. By sourcing scrap-recycled electric arc furnace (EAF) steel and using VOC-free electrostatic powder coatings, we help global buyers meet their ESG targets.
At Dongguan Hui Lian, quality control is handled by a team of 56 professional inspectors who track every stage of production, from raw steel selection to final container loading.
How we manage manufacturing lead times, domestic raw material supply, and international logistics.
Our relationships with top domestic steel mills ensure we receive continuous deliveries of high-grade coils (Q235B and Q355B). This stability helps us protect pricing and delivery timelines, even during volatile market cycles.
Our R&D team of 126 professional engineers supports custom beam lengths, unique post punch profiles, custom colors, and special wire mesh configurations, ensuring new hardware integrates smoothly with your existing warehouse systems.
Industrial shelving is bulky. We design flat-pack, stackable packaging systems to maximize shipping container space, lower freight costs, and ensure structural steel components arrive free from scratches and deformation.
Technical advice and procurement details for warehouse managers, purchasing agents, and industrial system engineers.
Safe load capacities are calculated based on uniformly distributed loads (UDL). We analyze column cross-sections, beam properties, and connection types using finite element analysis (FEA) software, and verify these calculations with physical destruction load testing.
Q235B is the standard choice for general-purpose industrial racking, offering excellent weldability and structural strength. For high-density racks, heavy tall systems, or low-temperature warehouses, Q355B steel is preferred due to its higher yield strength and performance under cold conditions.
Yes. We manufacture and test our systems to meet key international standards, including European EN 15512, Australia's AS4084-2012, and the North American RMI specifications, ensuring compliance for global project installations.
Boltless designs feature interlocking slots and tabs (using keyhole or butterfly punch shapes) that require no hardware. This simplifies assembly, reduces setup times by up to 60%, and makes it easy to adjust shelf heights without special tools.
Yes. We offer OEM/ODM fabrication, including custom structural steel sizes, custom punched hole spacing, and matching brand identity colors via our automated powder-coating lines.
Standard sizes are usually processed and shipped within 15 to 20 days. Custom configurations requiring tooling setups, complex punching, or custom welding take 25 to 35 days, depending on quantity and order backlog.
We apply multi-stage surface treatments, beginning with acid pickling and phosphating to clean the steel, followed by an electrostatic application of epoxy-polyester powder coat baked at 180-200°C. We also supply hot-dip galvanized finishes for high-humidity environments.
We need building floor plans, ceiling clearance heights, floor load capacity (kg/m²), planned load types, pick frequencies, and details on material handling equipment like forklifts or conveyors.
