Corporate Identity & Background
Established officially in 2014, Nanjing Everack Storage Equipment Co., Ltd. stands as a premier enterprise built upon 12+ years of core industrial experience in structural layout, stress analysis, and steel rolling technology. Centered in Nanjing's key manufacturing zone, we process large-scale industrial orders destined for North America, Western Europe, and Australia. Our professional capabilities have positioned us as a highly trusted supplier for multinational logistics corporations and heavy machinery factories.
Rigid Quality Inspection Systems
Quality control is embedded at every phase of our automated production lines. We support a specialized quality detection standard strictly aligned with ISO 9001, CE, and AS4084 structural safety guidelines. Our QC division employs 45 certified quality inspectors who conduct ultrasonic flaw testing on raw structural steel (primarily Q235B and Q345B grades), weld seam magnetic particle testing (MPT), and salt spray corrosion resistance testing to guarantee operational safety in cold or high-humidity environments.
Why Source Vertical Storage Units from Chinese Manufacturers?
How local production clusters, raw material supply networks, and engineering efficiencies reduce global procurement costs.
1. Unmatched Steel Supply Chain Synergy
Nanjing, China, is one of the world's most concentrated clusters for industrial racking fabrication. By partnering with over 1,200 upstream material suppliers, automated powder coating providers, and precision hardware manufacturers, Everack secures premium raw materials at baseline cost, insulated from sudden global market shifts.
2. Advanced Automated Roll-Forming Lines
Chinese factories utilize high-speed robotic welding cells and continuous automated upright roll-forming mills. This ensures a dimensional tolerance of less than 0.5mm across vertical columns and load-bearing beams, which is critical for complex integration in automated storage and retrieval systems (AS/RS).
3. Cost-Effective Engineering Customization
Our professional structural engineering team of 68 specialists can rapidly design and prototype custom steel profile iterations. We leverage Finite Element Analysis (FEA) to maximize load bearing-to-weight ratios, saving overseas clients up to 35% in material costs compared to domestic production.

Macro Industry Solutions & R&D Customization
We deploy Finite Element Analysis (FEA) to engineer high-capacity, seismic-resistant vertical storage systems.
Advanced Engineering Frameworks
Every vertical storage unit is calculated using advanced structural simulation software. By running 3D CAD modeling alongside physical load stress tests, our 68 R&D engineers optimize the vertical system load configurations from 500 kg up to 4,000 kg per level. Our designs incorporate specific safety factors required by the target destination country (e.g. RMI standard in the USA, AS4084 in Australia, and EN 15512 in Europe) to manage structural fatigue and accidental forklift collisions.
Custom Engineering & Surface Finishes
- Flexible Dimensional Profiles: Customized beam span lengths, dynamic frame depths, and precise column steel thicknesses ranging from 1.5mm to 3.0mm.
- High-Durability Surface Coatings: Options including electrostatic epoxy powder coatings, pre-galvanized components, and hot-dip galvanized steel for sub-zero cold-chain facilities or humid outdoor depots.
- Safety Accessories: Integration of modular column protectors, rack end barriers, wire mesh decks, back-stop beams, and specialized seismic baseplates.
Industry Trends & Localized Applications
The convergence of automation, robotics, and safety compliance in modern warehousing.
AS/RS Integration
Modern vertical storage structures are increasingly adapted to support high-speed Automated Storage & Retrieval Systems (AS/RS). These frameworks require highly precise structural tolerances, perfectly straight vertical columns, and specialized guiding rails for automated shuttles and cranes.
Dynamic Cold Storage
With global cold chain demand increasing, vertical storage units must withstand temperatures down to -30°C. Everack uses low-temperature grade steel and specialized anti-cracking powder formulations to prevent structural embrittlement under freezing conditions.
E-commerce 3PL Hubs
Rapid SKU turnover requires modular vertical shelving systems that can be quickly adjusted. Everack designs boltless and teardrop-style vertical systems, allowing operators to change beam configurations dynamically without specialized tools.
Overcoming Global Sourcing Barriers
How Everack addresses logistics safety, compliance certification, and ocean container optimization.
The Challenge of Transit Damage & Packaging
Racking frames and beams are susceptible to bending during long-distance maritime shipping. Everack uses advanced packaging solutions, including heavy-duty cardboard edge protectors, polyester strapping, and multi-layer bubble wrap protection. Wood pallets are fully fumigated, complying with ISPM 15 standards, to guarantee smooth customs clearance at European and North American ports.
Engineering Compliance & Structural Certification
Different jurisdictions require specific compliance certificates. Our structural engineering department provides calculation files validated against European EN codes, Australian AS4084 guidelines, and American RMI specifications. We provide complete structural calculation documents to support local building permit applications for our industrial clients.
Frequently Asked B2B Procurement Questions
Clear, technical answers regarding certifications, materials, customization limits, and payment processing.
Q1: Which international standards do Everack vertical storage units comply with?
Our storage units are engineered to comply with global safety standards, including Australia’s AS 4084-2012 steel storage racking standard, Europe’s EN 15512 / FEM 10.2.02 guidelines, and the United States’ RMI (Rack Manufacturers Institute) specifications. Our manufacturing plant operates under certified ISO 9001:2015 quality management controls.
Q2: What grades of steel are used in Everack warehouse racks?
We primarily use high-grade structural steel, specifically Q235B and Q345B (equivalent to ASTM A36 and ASTM A572 Grade 50). These materials offer optimal yield strengths to prevent deflection and structural failure under maximum loaded capacities.
Q3: How does the factory calculate load capacity per storage level?
We perform Finite Element Analysis (FEA) using specialized structural design software to simulate static and dynamic loading. We calculate column profiles and beam configurations with a safety factor of 1.5 to 1.8 to ensure structural stability under uneven loads.
Q4: Are your storage systems suitable for high-humidity or cold storage environments?
Yes. We offer hot-dip galvanized finishes (conforming to ISO 1461) and specialized epoxy powder coatings. These treatments protect components from oxidation and corrosion in harsh conditions like sub-zero cold rooms or damp marine environments.
Q5: What is the typical lead time from design approval to delivery?
A standard 40ft container order takes 20 to 25 days to manufacture once CAD engineering drawings are approved. Custom profiles or specialized hot-dip galvanized finishes may extend production timelines by 7 to 10 days.
Q6: Do you provide third-party engineering certifications?
We work with leading testing companies like SGS and TÜV Rheinland to provide independent material stress, steel grade, and coating thickness reports. We can arrange certified structural calculations to support local building permit applications.
