ASTM Walkway Grating
ASTM/NAAMM walkway mesh is one of the internationally recognized standards for expanded metal mesh. ASTM expanded metal mesh is a rigid, single-piece metal sheet that is slit and stretched to form diamond-shaped openings. With its high strength-to-weight ratio, excellent durability, anti-slip surface, and good drainage performance, it is widely used for heavy-duty industrial walkways, catwalks, platforms, and safety flooring.
Similar expanded metal products can also be manufactured according to BS, AS/NZS, JIS, and CNS standards. Known for their strength, toughness, and stable performance, these products are suitable for public works, industrial facilities, maintenance walkways, safety platforms, solar energy pathways, and offshore wind farm walkways.
