Dense Steel Grating (Stainless Steel) is a high-safety, corrosion-resistant flooring solution made from premium stainless steel (201/304/316). It features closely spaced bearing bars (≤25 mm, typically ~17.5 mm or ~20.6 mm) with 3–8 mm thickness, paired with anti-slip checker plate or wire mesh cross bars. This dense design prevents small object drop-through, meets high heel/ball-proof standards, and supports pedestrian to light/medium vehicle loads. Panels (up to 3000×6000 mm) are custom-shaped, mechanically polished, electropolished, or passivated for superior hygiene and durability in harsh environments.

Engineering Notes:
Dense stainless steel grating prevents small objects from falling while providing high friction under wet or oily conditions. With proper grading and spacing, the grating meets international standards for pedestrian safety (high heel proof) and industrial load requirements. Surface finishes such as electropolishing and passivation further enhance corrosion resistance in advanced chemical, marine, and high-humidity applications. Custom cuts, shapes, and edge finishing ensure flawless integration into complex industrial and architectural layouts.
