Optimizing global supply chains with high-precision engineering, automated AS/RS integration, and structural safety. Engineered for peak industrial efficiency.
A premier manufacturer specializing in heavy-duty industrial racking and smart warehouse storage systems.
Leveraging over 12 years of industry experience and 8 years of international trade expertise, Sunli Rack provides high-capacity, safe, and custom-designed structural racks. Operating from our advanced facility spanning 38,000 m², we engineer state-of-the-art storage infrastructures tailored to global high-density warehouses, cold chain logistics, and major e-commerce hubs.
We maintain an annual export revenue between $18 million and $25 million, consistently serving logistics systems and industrial distributors in North America, Western Europe, Southeast Asia, and the Middle East. Through a robust system of raw material tracing, rigorous load calculations, and automated manufacturing, we guarantee the durability of every frame, beam, and connector we ship.
From verified raw materials to automated surface treatment, every production stage is carefully monitored to comply with international logistics standards.
We source premium, certified steel coils. Our laboratory performs initial material thickness, chemical composition, and load-bearing testing prior to manufacturing release.
Advanced continuous rolling machinery shapes raw steel into upright profiles, ensuring consistent cross-sectional geometry and exact dimensional accuracy.
Heavy-duty saws and automated shearers cut columns and beams to precise lengths, keeping deviation margins to less than 1 millimeter.
Robot welders execute clean, uniform weld beads on load-bearing brackets and beam connectors, ensuring joint strength and consistency.
Automated powder coating lines clean and apply electrostatic epoxy-polyester coatings, forming a highly durable, corrosion-resistant outer finish.
Hydraulic presses form heavy-duty steel baseplates, safety clips, and bracing connectors with tight tolerances for exact fit and structural stability.
Batch samples undergo trial builds to verify system alignment, connector seating, and safety lock configurations before mass production.
Components are tested for coating thickness, hardness, impact resilience, and mechanical load limits by our 35-member QC team.
Finished components are bundled, bubble-wrapped, and strapped onto export pallets to prevent transit damage during container shipping.
Equipped with specialized high-speed rolling lines, robotic welders, and precise profiling equipment to meet large-volume industrial demands.
High-precision cold saws deliver clean perpendicular cuts, preventing raw profile deformation.
Continuous roll-forming system dedicated to standard structural uprights with zero twist.
Customized profile rollers designed for medium-duty shelf frames and long-span uprights.
Fast-cycle rolling mill engineered for retail display and shelving system profiles.
High-speed press punching precise pitch patterns into cold-rolled profiles with high repeatability.
Dedicated production system shaping box, step, and structural channels for load beams.
Multi-stage pre-treatment, drying, and powder coating curing for anti-rust protection.
Forms high-capacity sheet steel shelves, including safety-bended edges and reinforcement ribs.
CNC-controlled bending machine shaping custom steel baseplates and structural angles.
High-precision multi-point welding for secure connector attachment to beam ends.
Specialized rolling line for tie-bars, palette support beams, and structural cross members.
Heavy-tonnage press stamping thick gauge connection brackets, safety locks, and accessories.
Roll-forms step profiles designed for wire mesh decks, step-deck steel plates, and custom shelving configurations.
Our 28 skilled R&D engineers design and optimize structural profiles, releasing over 120 new products and improvements yearly.
Detailed CAD designs optimized for space utilization, material savings, load capacities, and structural compliance with RMI and FEM specifications.
Computer-based FEA simulations analyze mechanical stresses, seismic reactions, and load deformation limits under variable temperatures.
Industrial 3D printers output functional prototype components, verifying connector locks, safety clips, and accessories before hard tooling is cut.
Our customizable services accommodate tailored load capacities, custom rack dimensions, color powder coatings, and automated storage systems (AS/RS). We coordinate with 800+ supply chain partners to deliver dynamic industrial racking installations.
Managed by 35 QC professionals, our testing laboratory reviews raw materials, coatings, and weld joints to ensure long-term stability.
Measures mechanical impact resistance of cured powder coatings, preventing chipping under impact.
Tests paint adhesion quality to ensure the powder coat layer remains bonded to the steel substrate.
Verifies powder coat Dry Film Thickness (DFT) against specifications to guarantee corrosion protection.
Verifies linear length dimensions and hole pitch spacings against production blueprints.
Measures exact sheet steel and wall thicknesses, ensuring load-bearing materials match specification.
Measures long-span components and straightness tolerances on high-bay uprights.
Verifies perpendicular vertical alignment of structural models and mockups during testing.
Supplies regulated voltage to electro-chemical testing stations, assessing corrosion resistance.
Applies controlled thermal stress to powder-coated profiles, evaluating coating adhesion in hot environments.
Measures pull-out and shear load capacity of structural anchoring bolts and connectors, ensuring floor anchor stability under extreme loads.
Providing industrial racking to 3PL providers, industrial distributors, e-commerce hubs, and retail enterprises globally.
