Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. delivers heavy-duty custom logistics infrastructure engineered for safety, density, and seamless robotic warehouse automation.
Established in 2015, Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. has developed into a premier global manufacturer of heavy-duty industrial racking systems and intelligent warehouse storage infrastructure. Operationally situated within a modern 38,000 m² manufacturing plant, we run high-capacity automated production networks to guarantee precision tolerances on structural load-bearing parameters.
We combine over 12 years of core industry engineering experience with 8 years of specialized international trade operations, allowing us to manage complex export logistics and installation regulations worldwide. Our annual export trade revenue continuously spans between $18 million and $25 million, confirming our status as a trusted tier-1 structural storage vendor.
By exporting to core markets across North America, Western Europe, Southeast Asia, and the Middle East, we conform to stringent local building safety standards, including FEM, RMI, and AS4084 structures.
From certified raw structural steel sourcing to electrostatic powder coating lines, every operational stage is carefully managed to guarantee load capacity performance under stress.
High-tensile structural steel profiles inspect for metallurgical consistency and thickness uniformity.
High-precision rolling lines shape steel into rigid upright columns and horizontal support beams.
Automated cutting machinery cuts structural members to exact dimensional lengths.
Robotic MIG welding achieves deep, uniform weld penetration for strong beam connector brackets.
Automated chemical pre-treatment and electrostatic powder spray curing prevent rust.
Heavy-tonnage mold tools shape accessories, bracing plates, and baseplates.
Pre-assembly checks verify slot alignment and connector tolerances.
Simulated stress testing applies physical load to verify rated load limits.
Our facility operates a modern array of automated machinery to support custom, high-volume production for international warehousing projects.
High-precision structural profile cutting, holding dimensional tolerances within ±0.5mm limits.
Forms thick steel sheets into heavy-duty upright frames to support standard pallet weights.
Optimized for fabricating medium-load industrial shelving frames and cross-bracing profiles.
Specialized line designed for light shelving units and hand-load storage profiles. This continuous system combines roll forming and hole punching steps to improve production throughput.
Applies custom-pitch slots, teardrops, and mechanical hook configurations directly into structural steel profiles before roll forming.
Continuous roll profiling system engineered for high-rigidity box beams.
Automatic powder application and heating oven for impact-resistant surface finishes.
Folds and stamps steel decking panels with integrated reinforcement ribs.
Provides precise structural bending angles for heavy connection brackets and custom plates.
Multi-axis robot welding ensures clean, uniform joints on heavy-load structural connectors.
Rolls and processes cross-bracing profiles for AS/RS structures and tall pallet systems.
Presses heavy-gauge connector plates to exact spacing patterns for safety locking pins.
This high-capacity system produces stepped-profile cross beams designed to hold wire mesh decks or step-in support shelves. The step design creates a flush surface, protecting storage packages and strengthening the horizontal shelf structure.
Precision spatial design for industrial storage optimization.
Sunli relies on our dedicated team of 28 skilled R&D engineers to develop high-performance warehouse structures. We design to improve structural stability and optimize material usage, introducing over 120 new products and structural improvements annually.
Our engineers use advanced CAD software, Finite Element Analysis (FEA), and 3D printing prototyping to evaluate how complex racking assemblies respond under full-capacity weight loads. We customize racking height, depth, column thickness, and beam profiles to match regional seismic zone safety codes.
Whether integrating smart shuttle carts, cold-chain drive-in systems, or multi-level mezzanine structures, our R&D group provides comprehensive engineering support from initial CAD concept drawing to final structural certification.
"Our engineering goal goes beyond saving space—we focus on building load-bearing structures that maintain structural alignment over decades of intense industrial forklift operation."
Sunli R&D Engineering DivisionOur dedicated team of 35 QC professionals manages quality validation. We check physical tolerances on raw steel sheets, inspect weld seams, and test powder-coat thickness using specialized laboratory instruments.
Tests paint adhesion and impact resistance to prevent surface chipping during heavy pallet loading.
Performs cross-hatch cuts on coated samples to verify chemical bond strength against moisture.
Measures protective coating layers in micrometers to guarantee rust protection in humid air.
Calibrates linear cut dimensions across long horizontal beams to secure safe structural alignment.
Verifies sheet steel thicknesses to prevent structural deflection below nominal ratings.
Measures full rack frame profiles during test assembly to verify vertical height tolerances.
Checks horizontal coordinate alignment, verifying load distribution across anchor bases.
Powers simulated electrochemical corrosion tests to evaluate the paint coating's rust resistance.
Applies thermal stress to verify powder coat elasticity, preventing cracking under temperature shifts.
The digital display bolt drawing instrument applies vertical extraction force directly to anchor bolts fixed in concrete test blocks. This step determines the shear and pull-out resistance limits of anchoring hardware. Ensuring these parameters prevent racking systems from tipping during high-frequency forklift operations.
We work with over 800 supply chain partners to deliver custom layouts matching specific load-carrying capacities, facility shapes, and handling equipment.
We configure racking systems with columns up to 120mm in width and material thicknesses up to 3.0mm, accommodating load demands exceeding 5,000 kg per level. Multi-tier mezzanine spaces and high-bay structures are engineered to handle dense pallet storage while retaining structural safety factors.
We manufacture racking sections to tight tolerance specifications to support automated storage and retrieval systems (AS/RS). Our high-bay rack structures integrate with automated cranes, pallet shuttles, and conveyor systems, minimizing deflection along travel rails.
Adjustable pallet rack designs that configure easily to accommodate fast-moving inventory and shifting pallet shapes.
High-density pick modules and multi-level shelving structures designed to organize high stock-keeping unit (SKU) counts.
Cantilever systems and mold-storage racks built to handle long, heavy, or irregularly shaped parts safely.
Whether expanding an existing distribution center or developing a fully automated AS/RS high-bay facility, Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. provides engineered structural stability. Partner with an experienced manufacturer managing 38,000 m² of modern production capacity.
