Wholesale Anti Slip Stainless Steel Plate Factory

Anti‑slip stainless steel plates are produced by modifying the surface of austenitic stainless steel to increase traction while retaining the alloy’s corrosion‑resistant properties. The engineered texture raises the static coefficient of friction under wet or oily conditions, which helps reduce slip hazards in industrial walkways, platforms, and equipment guards. Typical surface patterns are formed by cold rolling or laser processes, creating repeatable protrusions that measure a few tenths of a millimeter in height.

Material and Surface Treatment

The base material is usually AISI 304 or 316L stainless steel. Both grades contain approximately 18‑20 % chromium and 8‑10 % nickel, with 316L adding 2‑3 % molybdenum for improved resistance to chloride environments. Surface patterns such as diamond‑shaped dimples, linear grooves, or cross‑hatch are impressed onto the sheet during a cold‑rolling pass. Pattern depth is controlled between 0.10 mm and 0.30 mm, and the resulting surface roughness (Ra) typically falls in the range of 2.0 µm to 4.5 µm.

Manufacturing Process

Production begins with hot‑rolled coil that is annealed and pickled to achieve a uniform microstructure and remove scale. The cleaned coil then passes through a set of embossing rolls that impart the chosen pattern at room temperature, followed by a levelling step to ensure flatness. After patterning, the sheet undergoes a passivation bath (nitric acid or citric acid) to restore the protective chromium‑oxide layer, and a final inspection verifies dimensional tolerances and pattern consistency.

Technical Specifications

Quality Assurance and Testing

Dimensional tolerances follow ISO 2768‑m for thickness, width, and length, with typical deviations of ±0.10 mm for thickness and ±2 mm for width and length. Surface roughness is measured with a contact profilometer to confirm that Ra stays within the specified range. Salt‑spray exposure per ASTM B117 is conducted on representative samples to verify that no red rust appears after 500 hours for 304 and 1000 hours for 316L. Visual inspection under 10× magnification checks for pattern uniformity, edge burrs, and surface defects.

Applications

In food‑processing facilities, floors and walkways must resist frequent wash‑downs with alkaline cleaners while providing secure footing for workers; the combination of chromium‑rich passive film and the engineered texture satisfies both hygiene (easy to clean) and slip‑resistance requirements. On offshore platforms and ship decks, the alloy’s resistance to chloride‑induced pitting prevents localized corrosion, and the slip‑resistant surface reduces the likelihood of accidents during wet operations or when decks are coated with oil or spray. In chemical plants, where spills of acids or solvents may occur, the stainless steel substrate maintains integrity, and the texture continues to offer traction even when contaminated with low‑viscosity liquids.

Customization Options

Packaging and Logistics

Finished sheets are interleaved with low‑static polyethylene film to prevent surface marring, then stacked on wooden pallets with corner protectors. For export shipments, moisture‑absorbing desiccant packets are added, and the pallet is wrapped in stretch film and secured with steel strapping. Pallets are labeled with grade, dimensions, heat number, and inspection status to facilitate traceability.
