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.
As a premier custom OEM library shelving supplier, DirectRack leverages high-grade materials such as cold-rolled carbon steel, Q235B high-tensile steel, and custom powder coatings to fabricate structurally sound, long-lasting storage architectures. Our facility supports full ODM processes—from early CAD detailing and finite element analysis (FEA) to industrial-scale production.
China's advanced manufacturing hubs lead the world in integrated steel production, high-precision metal fabrication, and advanced robotic finishing. Discover why global buyers prefer Chinese OEM partnerships for institutional library projects.
Direct proximity to top-tier steel smelting centers allows DirectRack to lock in high-quality structural steel grades (such as Q235B and Q345B) at highly competitive costs. This direct-from-mill raw material sourcing shields international purchasers from the price volatility commonly found in regional secondary markets.
Our facility features high-throughput machinery, including CNC multi-station rolling machines, laser cutters, and automated robotic welding arms. This guarantees tight tolerances (within ±0.1mm) on structural frames, ensuring quick assembly at the installation site.
We operate fully automated multi-stage pre-treatment and powder coating lines. Utilizing specialized architectural thermosetting epoxies, our library shelves deliver high abrasion resistance, anti-scratch surfaces, and neutral VOC properties for indoor environments.
From high-grade raw carbon steel to powder-coated structures, discover our fully documented factory processes ensuring premium product quality.
Modern educational and archival centers are moving away from traditional single-purpose static shelving. In the era of data integration and digital resource optimization, libraries require adaptive spatial layouts that maximize footprints while maintaining ease of access.
Enterprise procurement professionals must balance structural performance, longevity, and regulatory compliance. At DirectRack, we optimize structural profiles to align with critical international criteria.
Whether supplying standard cantilevers for community libraries or manufacturing structural profiles for large research institutions, our design teams run comprehensive calculations to ensure safety under heavy static and dynamic loads.
"Integrating high-density mobile storage, automated inventory tracking, and eco-friendly raw materials is crucial for contemporary institutional archivers who demand long-term value."
We engineer and supply library storage architectures across various settings, customizing load ratings and visual aesthetics to match specific spatial designs.
Academic facilities require high load-bearing shelves to support oversized reference books and heavy journals. Our structural steel frames prevent shelf deflection under continuous heavy loads, ensuring student safety.
Long-term document storage requires clean environments. Our powder-coated systems are chemically inert and off-gas free, preventing document degradation over decades of use.
We design systems with modular floor tracks, smooth mechanical-assist steering, and anti-tip mechanisms, enabling operations to double capacity within their existing structural footprint.
DirectRack maintains strict quality governance enforced by 28 specialized QC inspectors. Our quality control framework adheres to international AS4084 and OSHA safety standards. Our standard product inspection methods include X-ray weld seam analysis, coating thickness measurement via magnetic gauge, column compression destruction tests, and full-scale beam deflection loading tests to ensure zero-defect delivery.
We track our materials path from the raw steel coil to final surface finishing. This detailed documentation ensures that every batch meets design criteria for load bearing and yield strength, protecting your facilities from structural failure.
Detects internal micro-cracks in frame connections to ensure sound structural joints.
Verifies uniform powder coat thickness (measured in microns) to prevent oxidation.
Pushes upright structural frames to failure to establish real-world safety limits.
Measures horizontal deformation under load to comply with ANSI and EN specs.
Our engineering team works directly with architects and facility planners to convert spatial designs into manufactured systems.

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. Our custom 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.
Our R&D engineers use modern design software to run loading and safety simulations before manufacturing. This step minimizes physical prototype issues, accelerating product development and ensuring compliance with local building codes.
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. Our primary export markets include Southeast Asia, the Middle East, and South America. Our main client types range from retail distribution facilities and automotive parts warehouses to commercial FMCG wholesale hubs.
We work with international logistics providers to manage customs clearance, packaging, and shipping container loading, helping protect shipments from damage during maritime transit.
Get answers to common technical, logistics, and engineering questions asked by project managers and corporate buyers during the OEM design phase.
We primarily use Q235B and Q345B grade high-strength carbon steel. These structural alloys offer excellent yield strengths and structural properties under heavy load.
Yes. Our structural products are manufactured and checked against AS4084 (Steel Storage Racking) and OSHA regulations. We run deflection tests and weld seam analysis to confirm loading ratings before shipment.
Typical manufacturing cycles run between 30 to 45 days from engineering layout sign-off to container loading. Urgent projects can be expedited by our R&D team using automated CNC workflows.
Yes. We offer electrostatic powder coating in a range of colors and finishes. Our epoxy formulas are scratch-resistant, anti-uv, and low-VOC, meeting green-building standards.
We use double-wall corrugated boxes, corner edge boards, and high-density bubble wrap to pack our metal parts. Wood crating is available for export projects to prevent shifting in transit.
