Explore our industrial-grade, certified lightweight and medium-duty shelves designed for high-density warehouse storage operations.
An in-depth analysis of materials science, global compliance, and industrial load performance under 300KG per shelf level.
In modern supply chain and internal logisitics architectures, the stability and quality of inventory containment hardware dictate processing speeds and structural safety. As a preeminent force in the production of lightweight and medium-capacity racking systems, Chengdu CoreStorage Logistics Equipment Manufacturing Co., Ltd. offers unparalleled physical infrastructure and technical specialization.
Company Profile & Capacity Statement:
Founded in 2016, spanning a comprehensive factory area of 22,000 m², the company generates an annual export revenue of $15,000,000. We bring 6 years of global trade expertise alongside 11 years of specialized industrial rack manufacturing experience.
To ensure maximum load integrity, our quality control procedures adhere to ISO 9001 & CE Structural Safety Standards, utilizing advanced CMM Automated Dimensional & Load Stress Testing. Our Quality Department comprises 28 skilled QC inspectors. Functioning with an Integrated Manufacturer & Global Trading Hub background, our main markets are focused on the Middle East, South America, and Eastern Europe. We actively collaborate with 650 supply chain partners to serve diverse client groups, including cold storage operators, wholesale distribution chains, and automotive assembly facilities.
Driven by Intelligent Modular Racking Design, our innovation team provides flexible custom options such as corrosion-resistant galvanization, tailored column profiles, and adjustable beam heights. Last year, we successfully executed 28 new product releases, empowered by 18 R&D engineers.
The integrity of any warehouse system under load—even for systems rated under 300KG per shelf level—hinges entirely on materials chemistry and the structural layout of the vertical posts and horizontal beams. Our primary selection is Q235 Carbon Structural Steel, a grade revered for its optimal balance of ductility, yield strength, and exceptional welding properties.
Compared to lighter alternatives or low-grade sheet metals, Q235 steel ensures that under a Uniformly Distributed Load (UDL), structural deflection remains within the strict engineering parameter of L/200 (where deflection does not exceed 1/200th of the span length). Our profiles are manufactured utilizing automated cold-roll forming, resulting in work-hardened profiles that exhibit significantly higher load tolerance limits than hot-rolled equivalents of comparable thickness.
The carbon content (0.14% - 0.22%) and manganese additions in Q235 steel provide superb load stability and minimize stress-relaxation over years of continuous mechanical compression.
Advanced electrostatic powder coating and hot-dip galvanization processes create an impermeable barrier against humidity, ambient chemical agents, and physical abrasion.
Our custom upright beam geometries, featuring dynamic return flanges, disperse vertical stress pathways outward, preventing localized buckling under off-center placement.
Sourcing light-duty and medium-duty shelving from our Chengdu facility offers distinct systemic advantages to international enterprises. Thanks to highly integrated regional steel networks and automated tooling configurations, we reduce raw material waste and shorten structural fabrication lead times.
Additionally, our proximity to critical transport hubs enables us to coordinate complex multimodality shipping frameworks. We leverage our network of 650 supply chain partners to secure preferential access to raw materials and auxiliary components like plastic floor protectors and reinforced wooden decking panels. This ensures that every container shipped meets dimensional tolerances down to ±0.5mm, verified by our automated Coordinate Measuring Machines (CMM).
Lightweight warehouse shelves (rated <300KG) are the foundational backbone of several key industry sectors, balancing accessibility with footprint optimization:

Critical structural answers to ensure compliance, proper load calculations, and long-term durability of your systems.
Rated capacities (such as 300KG per shelf) are strictly calculated as Uniformly Distributed Loads (UDL). If inventory is concentrated in a single point (Point Loading), structural deflection limits will be exceeded at far lower thresholds. To protect structural integrity, always place heavy components near column nodes and span loads evenly across horizontal beams.
At CoreStorage, we use Coordinate Measuring Machines (CMM) to check physical profile tolerances down to sub-millimeter scales. Additionally, raw material batch samples are subjected to destruct and non-destruct load stress testing. This measures yield strength and ultimate tensile strength, ensuring full compliance with European EN 15635 static storage guidelines.
Q235 represents the optimal carbon structural steel sweet spot. It provides high yield strength (235 MPa) to withstand direct loads, combined with superior ductility that avoids brittle structural cracking under minor dynamic impacts, such as forklift movements.
Yes. For cold storage and high humidity environments, we offer customized corrosion-resistant galvanized profiles or high-grade stainless steel options. These prevent surface rust and oxidation degradation in temperatures as low as -40°C.
