Engineering and manufacturing heavy-duty industrial racks to maximize your storage capacity and warehouse safety globally.
Founded in 2016, Dongguan Dingguan Metal Products Co., Ltd. (DirectRack) is a technology-driven warehouse equipment enterprise located in Dongguan, Guangdong Province. Leveraging 10 years of industry expertise and 8 years of international export background, the company operates a state-of-the-art manufacturing plant covering 25,000 square meters of building area.
Our annual export revenue consistently exceeds $18 million USD, supplying premium steel storage systems to worldwide logistics networks. We are committed to building reliable, high-density storage solutions that scale with modern business demands, blending heavy-duty raw material procurement with highly sophisticated structural engineering design.
From primary structural steel coils to ready-to-install industrial storage racks, see how we build unmatched rigidity into every product.
We source high-grade Q235B and Q355B steel coils from premier domestic steel mills. Every batch undergoes strict tensile strength, yield point verification, and chemical composition analysis to ensure basic material integrity.
Using state-of-the-art CNC bending brakes, steel plates are bent to precise dimensional angles, creating structural elements with strict mechanical tolerances that resist lateral deformation.
Our automated cold-roll forming lines continuous-profile upright columns and beams. This continuous deformation process ensures consistent load distribution capacity along the full length of the steel profiles.
Our robotic and manual gas-shielded welding systems join structural connectors, baseplates, and beams. Full weld penetration prevents fatigue failures under continuous heavy industrial loading.
Prior to coating, steel members undergo aggressive shot-blasting. This removes all mill scale, rust, and surface impurities, creating a high-profile surface anchoring texture for paint adhesion.
Thermosetting epoxy-polyester powder is electrostatically applied and cured in 200°C tunnels. This produces a resilient, scratch-resistant barrier coating that prevents corrosion in high-humidity logistics zones.
Completed racks are carefully bundled using protective padding and high-tensile strapping. This ensures zero damage during long-distance multimodal logistics transfers to global sites.
Innovation is at the core of our business model. Spearheaded by 35 senior R&D engineers, DirectRack provides dynamic structural calculation models and fully bespoke modular storage designs. We simulate real-world physical forces to optimize weight-to-load distribution profiles.
Our custom engineering options feature customizable shelf depth/height ratios, multi-tier mezzanine configurations, anti-seismic bracing, and custom RAL color palettes. In the previous year, we successfully introduced 42 new product designs to meet evolving automated warehouse demands, ensuring our customers get exactly what their spatial layout demands.
Our investment in automated production assets ensures consistent precision, structural integrity, and short manufacturing lead times.
Performs high-speed continuous profiling to ensure consistent straightness and structural integrity in upright frame components.
Ensures high-precision pitch spacing for connector slots, supporting flexible beam height adjustments across the frame.
Provides rapid fusion of wire decking mesh grids, guaranteeing flat surfaces and uniform loading capabilities.
Semi-automated stations dedicated to joining structural baseplates, bracket connectors, and upright profiles seamlessly.
Cuts thick steel sheets down to exact layout dimensions with clean, burr-free edges, ready for further profiling.
Delivers precise angles and folds on raw steel panels, reinforcing support profiles for beam connectors and dividers.
High-precision robotic arms ensure continuous welding beads, uniform penetration, and minimal thermal distortion.
Uses high-velocity steel shots to clear oil and oxide scale, creating a clean substrate for electrostatic powder coating.
Our fully automated electrostatic spraying line ensures uniform dry film thickness and complete coverage on all steel surfaces.
Provides precise cutting lengths for heavy-duty structural steel profiles and hollow structural sections (HSS).
DirectRack maintains strict quality governance enforced by 28 specialized QC inspectors. Our quality control framework adheres to international AS4084 and OSHA safety standards, guaranteeing peace of mind in high-density facilities.
Our standard product inspection methods include:
Utilizing a seamlessly integrated OEM/ODM trade background, DirectRack has established strategic alliances with 650 supply chain partners across raw steel sourcing and automated surface treatment industries. This wide network helps us manage supply-side price fluctuations and guarantees reliable delivery schedules.
Our primary export markets include Southeast Asia, the Middle East, and South America. We supply customized storage systems to a variety of client profiles, including retail distribution facilities, automotive parts warehouses, and commercial FMCG wholesale hubs.
We build storage frameworks that withstand extreme stress, optimizing space utilization and operational throughput for heavy industries.
We selectively source structural Q235B and Q355B steel coils, ensuring superior tensile strength, ductility, and cold-bending performance for multi-tier applications.
Our design methodologies, manufacturing tolerances, and safety coefficients adhere strictly to European, Australian, and American warehousing safety guidelines.
The electrostatic powder coating film thickness is continuously monitored. This prevents corrosion and extends service lifespans under cold storage conditions.
CNC punching lines maintain upright beam adjustments within 50mm increments. Our tight connector engagement prevents upright twisting and beam rotation.
We customize high-strength horizontal and diagonal bracing systems, complete with heavy-duty anchor plates, to support operations in seismically active regions.
Key factors for selection and structural optimization.
A: Q235B is typical for standard pallet storage where structural height is moderate and load limits sit below 2,000 kg per level. For extremely high-density configurations, drive-in systems, or dynamic automated storage and retrieval systems (AS/RS), Q355B offers a higher yield strength (355 MPa vs 235 MPa). This enables narrower column profiles without sacrificing structural stability.
A: According to AS4084-2012, the beam deflection limit under safe working load (SWL) should not exceed L/200 of the span (where L is the length of the beam). For example, a 2700mm beam should not deflect more than 13.5mm under its maximum capacity. DirectRack runs real-world load testing on every layout to verify compliance with this standard.
A: Salt spray tests simulate long-term corrosion. Our epoxy-polyester coatings are subjected to 500-hour neutral salt spray tests, maintaining finish integrity with zero blistering. This layer performance protects storage rack steel from the moisture and chemical exposures common in distribution warehouses.
A: Please provide clear ceiling clearance heights, column spacing, floor slab load capacities, pallet dimensions (W x D x H), and forklift turning radiuses. Our engineering team uses this data to build a custom CAD layout showing dynamic calculations and optimized flow dynamics.
