Explore our primary industrial food equipment selections, engineered for deep compliance, structural rigidity, and thermal resilience.
In the demanding ecosystem of commercial bakeries, high-throughput food production lines, and industrial foodservice facilities, the structural integrity of thermal processing components dictates the margin between operational failure and sustained profitability. Among these components, commercial oven racks serve as the foundational load-bearing substrate. High-quality oven rack engineering must balance metallurgical precision, thermal expansion tolerances, and cleanability to comply with global food safety standards.
As a premier global supplier, Shandong Linru Import & Export Trading Co., Ltd. (historically known under manufacturing divisions like Feijin Import & Export) has accumulated over 15 years of industry-grade manufacturing expertise. We design commercial kitchen hardware that withstands the rigorous cycles of commercial operations. From initial configurations of custom single-line baking stoves to highly complex, multi-zone high-density rack configurations, our engineering methodologies focus on providing maximum Information Gain for procurement managers searching for resilient, long-lasting hardware assets.
Our manufacturing philosophy rejects the low-cost, low-quality paradigm. Instead, we invest heavily in metallurgical testing, advanced robotic welding, and automated surface treatment. This ensures that every oven rack, worktable, and integrated refrigeration assembly we deliver operates flawlessly under high mechanical loading and severe thermal cycling.
How Shandong Linru leverages structural, regional, and technological advantages to provide cost-efficient, high-volume production for international enterprises.
We source structural steel coils and wire rod stock from top domestic steel mills. This ensures consistent metallurgical composition, optimal tensile strength, and exact chromium-nickel ratios crucial for corrosion protection in steam injection baking ovens.
Equipped with state-of-the-art CNC multi-slide wire forming machines and automated gantry resistance welders, our facility produces high-capacity oven racks with spatial dimensional tolerances within ±0.5mm. This degree of accuracy prevents jams in automated rack-loading ovens.
Every production batch undergoes destructive shear testing on cross-wire weld points, along with salt-spray testing to verify the passivation layer of our 304 and 201 stainless steel configurations. This guarantees long-term durability in high-humidity proofing environments.
For international procurement managers, purchasing kitchen hardware from overseas presents regulatory challenges. A reliable supply chain partner must ensure that its products comply with local environmental, health, and structural safety codes. Shandong Linru establishes complete transparent documentation to satisfy these requirements.
Our commercial thermal processing and refrigeration units are designed to meet rigorous standards. Our heating equipment and stoves are certified under the full-range China Compulsory Certification (CCC). For specialized, high-pressure processing machines like jacketed kettles, we maintain the National Pressure Vessel Manufacturing License. This means our mechanical structures are rated for elevated temperature and pressure operations, ensuring safety and compliance across global jurisdictions.
Selecting the correct material grade is critical for both cost-efficiency and compliance. Grade 304 stainless steel contains a high composition of Chromium (min. 18%) and Nickel (min. 8%), rendering it highly resistant to organic acids and wet environments. It is recommended for cooking chambers with high steam levels. Conversely, Grade 201 stainless steel is an economical alternative optimized for dry rack applications, structural frameworks, and dry-storage settings.
Our manufacturing facility certifies the precise chemistry of all alloy stocks. This prevents chemical leaching when in contact with acidic food substances at high temperatures, satisfying the regulatory requirements of both the US FDA and European food safety bodies.
We design our products and processes to resolve the logistical and technical pain points of multi-unit chains, culinary suppliers, and large-scale industrial bakeries.
Specifically engineered for automated baking, featuring high wire density to maximize tray capacity without restricting hot air circulation.
Adjustable tier counts, wire gauges, structural reinforcement crossbars, and caster options to match your existing equipment line.
Our flat-pack rack designs reduce shipping volumes by up to 60%, significantly lowering sea freight and domestic transport costs.
We provide full material certs, factory dimensional check sheets, and load testing records for every shipment.
The commercial baking industry is transitioning toward increased automation, deeper digital integration, and strict environmental compliance. These market shifts require oven rack designs to evolve to handle higher thermal stress and continuous robotic loading.
Modern central food production facilities utilize AGVs to transport racks of dough from proofing cabinets straight into convection ovens. This requires rack bases to have exact dimensional tolerances and high mechanical rigidity. Our automated manufacturing line produces racks with precise tolerances to prevent indexing jams during robotic operations.
Standard mechanical polishing can leave micro-fissures in steel, where carbon deposits and food residue build up over time. Electropolishing, however, uses an electrochemical process to remove microscopic peaks on the metal surface. This produces a smooth, chrome-like finish that prevents dough adhesion, eases cleanup, and improves corrosion resistance.

Expert answers to common questions about industrial materials, structural load capacities, international regulatory standards, and design customization.
SUS304 contains higher concentrations of Nickel and Chromium, which provides excellent resistance to corrosion, high humidity, and organic food acids. It is ideal for steam ovens and baking processes with high humidity. SUS201 replaces part of the nickel content with manganese. While it offers similar structural strength and heat resistance, it has lower corrosion resistance. This makes SUS201 a cost-effective choice for dry baking, storage racks, and low-humidity applications.
Wire spacing and thickness directly affect both airflow and tray capacity. We design our rack grids to balance load-bearing strength with open area. This ensures uniform hot air distribution within convection baking chambers, preventing cold spots and ensuring consistent crust coloration.
For global compliance, materials in direct contact with food must be chemical-leach resistant and meet FDA or NSF regulations. Electrical and gas systems require CE or ETL marks in Western markets. Shandong Linru's products comply with CCC standards, and our high-pressure systems like jacketed kettles hold the National Pressure Vessel Manufacturing License.
Yes. We offer fully customizable rack designs. Customers can specify critical dimensions, including total height, width, depth, slide clearance, lock tab layouts, and wheel/caster configurations, to ensure compatibility with rotation ovens from brands like Revent, Baxter, and Miwe.
Our standard double-tier and single-rack structures are designed to hold between 150 kg and 350 kg, depending on the wire gauge and reinforcement crossbars. For heavy duty needs, we add support gussets and use thicker frame tubing to prevent sag or warping under high temperatures.
Electropolishing removes surface impurities and smooths out microscopic cracks. This creates a surface that resists carbonized grease and food residue buildup, reducing the need for harsh chemicals during cleaning cycles and extending the service life of the rack.
Our extended range of heavy-duty preparation, cooking, refrigeration, and washing systems for global catering and central production facilities.
