SS Expanded Metal - Corrosion Resistance, good strength Stainless steel expanded metal is made of stainless steel metal sheet, through die slitting and stretching to form uniform diamond shaped openings. In the manufacturing process, no material is lost, and it offers savings in weight, as well as free passage of light, liquid, sound and air. Stainless steel expanded metal is more rigid than an equal weight of solid steel plate or wire mesh, making it popular in architectural and commercial areas. It is worth mentioning that 18 gauge (0.05" thick) 304 stainless steel and 316 L stainless steel are materials that commonly used. But there is difference between them, so choose suitable material for your needs, and the following information will help you learn more about stainless steel expanded metal. Feature Stainless steel 304 for anti-rusting and heat resistance. Stainless steel 316 has more corrosion resistance. Easy to be welded and cut for your ideal form. Resistant to high temperature and food grade stainless steel especially designed for BBQ grill. High mechanical strength for many applications that need large load bearing. Specification Material: stainless steel 304, 316, 316 L. Types: stainless steel - flattened expanded metal (more attractive than raised type), stainless steel - raised expanded metal.
