Description
Product Introduction
Expanded metal in stainless 304 and 316/316L for maximum corrosion resistance and hygiene. Raised or flattened, polished or mill. For food, chemical, marine, architectural and filtration use.
Product Introduction
Stainless steel expanded metal is the premium grade of the expanded mesh family, made by slitting and stretching stainless sheet into a one-piece diamond network that delivers outstanding corrosion resistance, strength and a clean, durable appearance. Zhongman produces it in grade 304 for general corrosion-resistant service and grades 316/316L for the most aggressive chemical, marine and high-chloride environments. Like all expanded metal it is formed from a single sheet, so there are no welds or joints to corrode or fail, and the diamonds provide consistent strength with substantial open area. Available in raised and flattened patterns and a range of diamond sizes and gauges, with mill, brushed or polished finishes, stainless expanded metal suits demanding applications in food processing, chemical plants, marine structures, architecture and precision filtration where hygiene, longevity and resistance to rust are essential.
Key Features & Advantages
Stainless expanded metal offers the best corrosion and hygiene performance in the range. Grade 304 resists most atmospheric and food-grade environments, while 316/316L add molybdenum for superior resistance to chlorides, acids and salt spray, ideal for marine and chemical service. The non-porous, smooth-cleaning surface meets hygienic requirements in food, pharmaceutical and medical settings, and the metal needs no coating, so there is nothing to chip or peel. One-piece construction means no weld points to crack or corrode, giving uniform strength and a long maintenance-free life. Stainless retains strength across a wide temperature range, is fire-safe and fully recyclable. Polished and brushed finishes provide an attractive architectural appearance, while high open areas allow precise control of airflow, light, drainage and filtration.
Specifications & Options
Zhongman supplies stainless steel expanded metal in grades 304, 316 and 316L, with diamond short-way dimensions from 3/16" to 2" and strand gauges from No.10 through No.22, giving open areas of roughly 30% to 89%. Customers select 304 for cost-effective corrosion resistance or 316/316L for chloride-rich, marine and chemical exposure. Both raised and flattened patterns are available, the flattened version giving a smooth face for visible or hygienic surfaces. Finishes include mill, pickled, brushed and polished. Panels are offered in standard 4ft x 8ft and custom sizes, and we cut, form, frame and fabricate pieces to drawings, including filtration discs and screen sections. Because grade and finish affect both performance and price, our team helps confirm the optimal specification for your corrosion, hygiene and aesthetic requirements.
Applications & Industries
Stainless expanded metal serves the most demanding industries. In food, beverage, dairy and pharmaceutical plants it forms hygienic guards, shelving, drying screens, walkways and equipment panels that wash down cleanly and resist corrosion. Chemical, petrochemical and water-treatment facilities use 316 panels for screens, filters, platforms and guards exposed to acids and chlorides. Marine and offshore structures rely on stainless for decks, gangways and barriers in salt environments. Architects specify polished stainless mesh for prestige facades, interior screens, ceilings and feature panels that stay bright for decades. Precision filtration and separation processes use fine stainless expanded mesh for sieving and straining. The metal also appears in medical, laboratory and high-temperature equipment wherever rust resistance, hygiene and durability are critical.
Why Choose Zhongman
Zhongman expands stainless 304, 316 and 316L in-house with careful control of diamond geometry, edge quality and finish, delivering mesh that meets corrosion, hygiene and architectural standards. We provide mill, brushed and polished surfaces and fabricate cut, formed and framed panels, filtration screens and facade cassettes to your drawings. Our team advises on grade selection so you neither over-specify costly 316 where 304 suffices nor under-specify in chloride environments. We supply material certificates and traceability for regulated food, pharmaceutical and chemical projects, and our export packing protects the polished surfaces in transit. Direct stainless sourcing keeps pricing competitive for a premium material, and responsive service supports orders from single sheets to large project quantities. For corrosion-proof, hygienic expanded metal, Zhongman is a trusted manufacturing partner.
