Why Stainless Steel Industrial Trays Are Essential for Food Processing

Stainless steel industrial trays are a cornerstone in modern food processing facilities, offering unmatched hygiene, corrosion resistance, and durability. Whether used for baking, meat processing, or central kitchen operations, these trays withstand harsh environments, frequent cleaning, and heavy loads. Their non-porous surface prevents bacterial growth, making them ideal for direct food contact. The combination of SUS 304 and SUS 316 grades ensures compliance with stringent food safety regulations, while customizable features like thickness, reinforcement, and perforation patterns optimize performance for specific applications.

Key Procurement Considerations for Industrial Trays

When sourcing food industry stainless steel trays, prioritize four critical factors: hygiene, corrosion resistance, load capacity, and stacking compatibility. Trays must be easy to clean (e.g., smooth surfaces, rounded corners) and resistant to acidic or salty foods. Stacking lugs or legs enable efficient storage and transport. For heavy-duty use, opt for thicker gauges (1.0–2.0 mm) and reinforced designs like pressed ribs or rolled edges (卷边). Custom perforated trays (冲孔) or mesh trays (网孔) are ideal for drying, conveying, or cooking where airflow or drainage is needed.

Material Grade Selection: SUS 304 vs SUS 316

Stainless steel food trays are commonly made from SUS 304 (18/8 stainless) for general food processing, baking, and central kitchens due to its excellent corrosion resistance and affordability. For harsher environments like meat processing or acidic ingredient contact, SUS 316 (含钼) offers superior resistance to chlorides and chemicals. Aluminum alloys (1060, 3003, 5052) are lightweight and thermally conductive but less durable; they suit light-duty cooling or conveying. Choose custom stainless steel trays based on your specific exposure to moisture, heat, and chemicals.

Thickness, Reinforcement, and Edge Designs

Plate thickness ranges from 0.5 mm to 2.0 mm, with thinner gauges (0.5–0.8 mm) for light loads and thicker ones (1.0–2.0 mm) for heavy or large trays. Reinforcement via pressed ribs or embossed patterns boosts rigidity without adding weight. Rolled edges (卷边) provide smooth, safe handling and prevent deformation. For high-stack applications, reinforced corners or added support bars extend tray life. Always specify thickness and reinforcement based on your industrial metal tray load requirements.

Perforated and Mesh Trays for Specialized Uses

Stainless steel industrial trays with perforations (冲孔) or wire mesh (网孔) are critical for drying, cooling, and baking where airflow or liquid drainage is needed. Common hole diameters: 1–10 mm, with customizable hole patterns (round, slot, square) and open area ratios. Perforated trays are often custom-sized to fit ovens, dryers, or conveyor systems. Mesh trays, welded from stainless steel wire, offer high open area for maximum ventilation but lower load capacity. Both types can be made in custom stainless steel tray dimensions (e.g., 400×300 mm, 600×400 mm, 800×600 mm) to suit your equipment.

Custom Sizing and Applications Across Industries

Custom stainless steel trays are available in any length, width, and edge height to match specific ovens, freezers, or transport carts. Applications include: food processing (marinating, rinsing), baking (dough proofing), meat industry (holding, chilling), central kitchens (prep, storage), cooling (air blast freezers), conveying (accumulation), and drying (spray dryers). For example, a bakery may use 600×400 mm perforated trays for bread cooling, while a meat plant needs 800×600 mm solid trays for brine contact.

How to Select the Right Industrial Stainless Steel Tray

Follow these steps: 1) Identify the process (baking, cooling, etc.) and load weight. 2) Choose material grade based on corrosion exposure (304 for most, 316 for acidic). 3) Determine thickness from 0.5–2.0 mm per load. 4) Decide on solid, perforated, or mesh based on airflow/drainage needs. 5) Specify reinforcement (ribs, rolled edges) for heavy stacking. 6) Provide custom dimensions to fit your equipment. 7) Verify stackability with existing trays or carts. 8) Order samples to test cleaning and durability.

FAQ: Common Questions About Stainless Steel Trays

What is the difference between SUS 304 and SUS 316 trays?

SUS 304 is suitable for most food applications; SUS 316 offers higher resistance to corrosion from chlorides and acids, ideal for meat processing or harsh cleaning chemicals.

Can I get custom-sized perforated trays?

Yes, we customize tray length, width, edge height, hole diameter, hole pattern, and open area to match your oven, dryer, or conveyor. Common sizes include 400×300 mm, 600×400 mm, and 800×600 mm.

Are these trays dishwasher safe?

Yes, stainless steel trays withstand high-temperature wash cycles and repeated cleaning without rusting or warping, provided they are properly reinforced for heavy wash loads.

Do you offer mesh trays for drying applications?

Yes, we produce welded mesh trays in various wire diameters and mesh openings to maximize airflow and drainage for drying and cooling processes.
