Stainless Steel Wire Shelf — Universal Model

L*W:1000*370/1000*470/1000*570/1200*370/1200*470/1200*570mm

Core Advantages

    Corrosion resistance – 304 stainless steel (18% chromium, 8% nickel) or 201 stainless steel (15% chromium, 1-5% nickel). Type 304 withstands 240 to 500 hours of salt spray testing (ASTM B117) without red rust; Type 201 withstands 96 to 168 hours. Suitable for fresh food sections, cold storage rooms, seafood processing areas, and environments with high humidity or potential contact with saltwater, mild acids (fruit juices, vinegar).

    Breathable structure – Mesh open area: 50% to 70%, allowing air circulation above and below the shelf panel. Suitable for products requiring ventilation (produce, baked goods) and packaged foods with condensation from coolers. Moisture drains through mesh openings, reducing surface water accumulation and bacterial growth.

    Load capacity – Stainless steel wire diameter: 3.0 to 4.5 mm. Frame edges reinforced with thicker stainless steel wire or flat bar. Per-shelf load range: 50 to 150 kg, depending on dimensions and stainless steel grade. The mesh structure distributes loads evenly.

    Size specification matching – Six standard sizes cover common shelf depth and length requirements. Lengths 1000 mm or 1200 mm fit standard single-span shelf beams. Widths 370, 470, and 570 mm fit different beam depths. After installation, all four edges overlap the beams with an overlap width of 15 to 30 mm.

    Installation convenience – Panels sit directly on shelf beams without tools. Downward flanges or locating slots on all four edges engage with beams, preventing panel sliding. For removal, lift the panel upward.

Frequently Asked Questions and Precautions

Frequently Asked Questions

Q: What is the specific corrosion resistance difference between 304 and 201 stainless steel?
A: 304 stainless steel has a higher nickel content (8%) than 201 stainless steel (1-5%). Nickel enhances resistance to chloride ions (salt) and acidic environments. Under identical salt spray testing conditions (ASTM B117, 5% NaCl solution), Type 304 shows red rust after 240 to 500 hours, while Type 201 shows red rust after 96 to 168 hours. For seafood sections, pickled food areas, or stores in coastal cities, Type 304 is recommended. In dry indoor environments, Type 201 meets basic rust protection requirements.

Q: Is a stainless steel wire shelf dishwasher-safe or high-temperature resistant?
A: Both 304 and 201 stainless steel are heat-resistant. They can be cleaned in dishwashers (water temperature up to 90°C) and sterilized with high-temperature steam (up to 120°C). Wipe dry after cleaning to prevent brown spots (not rust, but mineral deposits from water) around weld points. Long-term use of stainless steel cleaners maintains surface luster.

Q: Does load capacity decrease over time for stainless steel wire shelves?
A: Stainless steel does not exhibit creep or fatigue degradation within the rated load range. Under normal use conditions, load capacity does not significantly decrease over 10 years. However, long-term overloading causes permanent wire sagging or weld cracking, which is irreversible. Keep loads below 90% of rated capacity as a safety margin.

Precautions

    Before installation, confirm shelf beam spacing matches panel length. Each panel end must overlap the beam by at least 15 mm. Excessive beam spacing leaves the panel center unsupported, reducing load capacity.

    Install panels horizontally with uniform contact on all four edges. Angled installation causes loads to shift to the lower side, increasing local stress.

    Do not exceed per-shelf load ratings for the corresponding size and stainless steel grade. Overloading causes permanent wire sagging or weld cracking.

    Inspect beam overlap and weld points every 6 months. Replace panels with cracked welds.

    Clean with neutral detergent and a soft cloth or sponge. Avoid chlorine bleach, hydrochloric acid, or steel wool on stainless steel surfaces, which damage the passive film and cause localized pitting. Wipe dry after cleaning to prevent water spots.

    For small products (smaller than the mesh spacing), items may fall through gaps. Use fine-mesh stainless steel liners, food-grade plastic trays, or solid liners on top of the wire panel.

    This shelf is not intended for open liquid containers (lidless buckets). If such storage is required, place stainless steel catch trays on the shelf.

    Contact between stainless steel surfaces and carbon steel tools (standard wrenches, steel brushes) may cause iron contamination, leading to rust-colored spots. Use stainless steel-specific tools or protect surfaces with plastic/rubber pads during installation and maintenance.
