GI Expanded Metal, Epoxy Coated Steel Expanded, Stainless Steel Expanded Mesh in 304, 304L, 316 and 316L
Dinglian Co. supplies expanded metal, a versatile material created by slitting and stretching sheets of metal. This process forms diamond or other shaped openings, resulting in a lightweight yet strong mesh. Common uses include security fencing, grates, walkways, and architectural facades. Classifications often depend on the metal type (e.g., steel, aluminum), opening size, and thickness.
Material Type: Expanded metal is commonly produced from materials like carbon steel (various grades), stainless steel (e.g., 304, 316), and aluminum alloys (e.g., 3003, 5052), each offering distinct strength, corrosion resistance, and weight characteristics for diverse applications.
Sheet Thickness: The gauge or thickness of the original, unexpanded metal sheet significantly impacts the final product's strength and weight, typically ranging from very thin (e.g., 20 gauge) to much thicker (e.g., 1/4 inch) for heavy-duty uses.
