Anping Xinye Metal Wire Mesh Products Co., Ltd, located in the renowned wire mesh capital of China – Hengshui, Hebei, has been a trusted manufacturer and supplier of high-quality expanded metal products for over two decades. Our ASTM A240 Grade Flattened 16 Gauge Stainless Steel Expanded Metal Sheet is engineered to deliver superior strength, durability, and corrosion resistance for demanding industrial and architectural applications. Crafted from premium stainless steel that meets the rigorous ASTM A240 standard, this flattened expanded metal sheet offers a smooth, even surface ideal for applications where safety, ventilation, and aesthetics matter. With our advanced production lines and strict quality control, we ensure every sheet meets the highest dimensional accuracy and consistency. Explore how this versatile material can solve your toughest challenges.
Product Features & Technical Specifications
Our flattened expanded metal sheet is produced by expanding a solid stainless steel sheet into a diamond pattern, then flattening it to create a smooth, uniform surface. This process eliminates sharp edges, making it safer to handle and ideal for walkways, screens, and decorative panels. The 16 gauge thickness (approximately 1.5 mm) provides a robust balance between strength and weight, while the ASTM A240 grade stainless steel ensures excellent resistance to oxidation, chemicals, and extreme temperatures.
- Material Conformity: Fully complies with ASTM A240 standard for chromium and chromium-nickel stainless steel plate, sheet, and strip for pressure vessels and general applications.
- Flattened Design: The sheet is passed through a rolling mill after expansion to achieve a smooth, flat surface with reduced thickness variation – perfect for applications requiring a level finish.
- Diamond Opening Geometry: Precise diamond-shaped openings provide optimal airflow, light transmission, and drainage while maintaining structural integrity.
- Corrosion Resistance: Stainless steel grades (304/304L/316L available) offer superior resistance to rust, pitting, and crevice corrosion in harsh environments.
- Customizable Dimensions: We offer sheets in various widths (up to 4 ft / 1.2 m) and lengths (up to 8 ft / 2.4 m), with custom strand width and opening size available upon request.
- Versatile Finishing: Standard mill finish is supplied, but we can also provide brushed, polished, or powder-coated finishes to match your aesthetic requirements.
- Low Maintenance: The non-porous surface is easy to clean and requires minimal upkeep, reducing long-term operating costs.

Key Advantages for Your Business: The flattened expanded metal sheet eliminates sharp edges, reducing injury risk during handling and installation. Its smooth surface is easy to paint or coat, making it a favorite for architectural facades, decorative screens, and safety barriers. The open diamond pattern allows light and air to pass through, making it ideal for ventilation grilles, filters, and enclosures. In industrial settings, it serves as durable flooring, catwalk treads, and machine guards. The stainless steel construction ensures long service life even in wet, salty, or chemically aggressive environments, lowering replacement costs over time.
Quality Assurance & Customization: Every sheet is produced under strict quality control procedures. We use precision dies and calibrated presses to ensure consistent strand width and opening geometry. Our flattening process applies uniform pressure to achieve a thickness tolerance of ±0.005 in. If you need non-standard dimensions, special patterns, or specific surface finishes, our engineering team can work with you to develop a custom solution. We also offer small trial batches for prototyping.

Frequently Asked Questions (FAQ)
-
Q: What stainless steel grades are available for this expanded metal sheet?
A: We offer ASTM A240 Grade 304, 304L, 316, and 316L stainless steel. Grade 304 is suitable for general indoor and outdoor use, while 316L provides enhanced corrosion resistance for marine or chemical environments. Other grades can be supplied upon request. -
Q: Can I get custom sheet dimensions?
A: Yes, we can produce sheets in various widths and lengths up to 48 in (1220 mm) wide and 96 in (2440 mm) long. Custom strand widths, opening sizes, and patterns are also available. Please provide your requirements for a feasibility review. -
Q: What is the difference between standard expanded metal and flattened expanded metal?
A: Standard expanded metal has a rough, slip-resistant surface with raised edges. Flattened expanded metal is passed through a cold rolling mill after expansion, resulting in a smooth, flat surface with a uniform thickness. Flattened sheets are safer to touch, easier to paint/coat, and provide a more consistent appearance. -
Q: Is this product suitable for outdoor use?
A: Yes, especially when made from 316L stainless steel, which offers excellent resistance to UV, moisture, and salt spray. For less corrosive environments, 304 grade also performs well. We recommend selecting the appropriate grade based on your specific exposure conditions. -
Q: What is the typical lead time for orders?
A: For standard sizes and grades, lead time is usually 10–15 working days. Custom orders may require 15–25 working days depending on complexity and quantity. We always confirm the schedule before order confirmation. -
Q: Do you provide samples before bulk production?
A: Yes, we offer free samples (you pay shipping) for quality evaluation. We can also produce a prototype of your custom pattern to ensure it meets your expectations before mass production. -
Q: How is the product packaged to prevent damage during shipping?
A: We package sheets in wooden crates or pallets with protective foam and plastic wrap. For large orders, we can use steel strapping and corner protectors. All packaging is designed to withstand international shipping conditions. -
Q: Can you supply a Material Test Certificate (MTC)?
A: Absolutely. We can provide a mill test certificate from the stainless steel coil supplier, confirming compliance with ASTM A240. This is available upon request for each order.
