Engineered to maximize storage efficiency, load capacity, and operational safety in commercial facilities.
Founded in 2016, Dongguan Dingguan Metal Products Co., Ltd. (DirectRack) is a globally recognized, technology-driven warehouse equipment manufacturer and exporter. Based in Dongguan, Guangdong Province, our enterprise coordinates state-of-the-art manufacturing plants spanning a building area of 25,000 square meters. Guided by 10 years of structural engineering expertise and 8 years of international export pedigree, DirectRack delivers elite-grade steel storage solutions, generating an annual export revenue exceeding $18 million USD.
For hazardous, high-density, and weight-sensitive applications such as industrial paint storage, warehouse design requirements exceed standard structural specifications. Chemical storage environments require specialized layouts prioritizing anti-seismic resistance, chemically inert surface treatments, and highly localized compliance standards. DirectRack serves as a strategic structural partner, integrating advanced raw steel sourcing, computerized automated manufacturing, and rigorous loading test models to guarantee maximum warehouse optimization and total reliability.
Industrial paint storage shelves carry extreme weight capacities and require resilience to potential solvent spills, chemical off-gassing, and environmental moisture. Standard commercial racks fall short under these conditions. DirectRack's paint storage systems are constructed from high-tensile structural steel (primarily Q235B steel), processed through state-of-the-art cold-rolled profile forming machinery. Our manufacturing lines run specialized steps to ensure the physical integrity and corrosion resistance of the storage racking systems:
Our automated production line incorporates structural stamping, roll-forming, advanced robotic welding, and automated thermosetting powder coating. Chemical storage components undergo meticulous shot-blasting to strip surface scale and oxides, creating a highly tactile profile for optimal paint adhesion. Following preparation, an electrostatic spray molding process deposits a thick, scratch-resistant, and flame-retardant epoxy-polyester powder coat. This specialized finish ensures the steel framework remains fully protected against chemical corrosives, heavy industrial cleaning solvents, and high humidity levels common to storage environments.
Safety is paramount when storing heavy palettes of liquid paints, aerosol canisters, and raw chemical ingredients. DirectRack maintains strict quality governance enforced by 28 specialized QC inspectors. Our comprehensive testing frameworks adhere strictly to international standards, including AS4084 (Steel Storage Racking), OSHA safety parameters, and European FEM 10.2.02 structural guidelines.
Every production run undergoes a mandatory quality check protocol before leaving our facility:
Non-destructive X-ray testing detects microscopic internal pores, slag inclusions, or incomplete penetration within load-bearing joints, verifying total weld strength.
Using magnetic gauges, inspectors verify a uniform coating thickness (minimum 60–80 microns), preventing raw metal exposure and environmental corrosion.
Hydraulic test systems compress column profiles to failure limits, validating raw yield strengths and structural safety margins under high weight limits.
Additionally, full-scale beam deflection loading tests are conducted in-house to simulate real-world warehouse stresses. These tests guarantee that racking systems under maximum load do not exceed the deflection limit of L/200 (where L is the clear span of the beam). This level of quality assurance protects personnel, structures, and inventory, minimizing the risk of racking failure.
The global paint and coatings market is undergoing a rapid transition toward high-solids, waterborne, and eco-friendly chemical compositions. Consequently, storage solutions must adapt to distinct weight profiles, volatile organic compound (VOC) management standards, and temperature-controlled storage dynamics. Industry-wide market analysis highlights key trends shaping today's procurement demands:
DirectRack delivers comprehensive, end-to-end industrial storage solutions tailored to global distribution networks, chemical processing plants, and retail supply chains. Leveraging an integrated OEM/ODM development process, we work with over 650 supply chain partners to offer custom structural configurations:
Engineered for high-volume paint distribution hubs, supporting up to 4,000kg per level. Features adjustable beam connectors, anti-seismic brace sets, and heavy-duty frame protectors.
Converts unused vertical headroom into functional storage floors. Utilizes high-strength steel grid plates, safety handrails, and integrated loading gates to double floor-space efficiency.
Perfect for non-standard, long-form materials or bundled raw inputs. Provides unobstructed front access, making it ideal for oversized paint crates or industrial coating rolls.
Our engineering department, staffed by 35 senior R&D engineers, utilizes advanced finite element analysis (FEA) software to simulate weight distributions and structural responses under extreme seismic scenarios. This design process ensures every custom storage layout fits seamlessly into the client's operational workflow.
Shipping structural steel globally requires a deep understanding of import regulations, regional quality standards, and logistics tracking. DirectRack exports to key global regions, including Southeast Asia, the Middle East, and South America. We supply distribution hubs, automotive facilities, and commercial FMCG warehouses.
To ensure smooth international delivery, we offer:
As industrial operations shift toward automation, warehouse racking is evolving from static storage frames into integrated elements of smart warehousing systems. DirectRack is actively developing technologies to support this transition:
Our R&D roadmap focuses on integrating structural racking with automated shuttle systems, vertical lift modules (VLMs), and real-time inventory tracking networks. We are designing ultra-precise rack frames compatible with high-speed crane systems, requiring alignment tolerances within 1.5mm. Additionally, we are developing chemical-resistant sensor mounts and smart wire-deck routing to support active environmental monitoring, helping facilities track temperature and safety metrics within hazard-prone paint storage zones.
High-yield steel construction designed for warehouse logistics, retail displays, and heavy commercial loads.
