As a leading manufacturer from Anping, Hebei, China, Anping Xinye Metal Wire Mesh Products Co., Ltd specializes in producing high-quality expanded metal mesh tailored for demanding industrial applications. Our 304 Stainless Steel Expanded Metal Mesh with a 3mm thickness and 10x20mm diamond opening is a robust, versatile, and corrosion-resistant solution designed to meet the needs of construction, filtration, security, and architectural projects. Each sheet is precisely expanded from a single piece of 304 stainless steel, ensuring no weak points from welding or weaving, and is delivered in a standard 4x8ft (1220x2440mm) sheet with a clean mill finish.
Product Features & Technical Specifications
- Material: Premium 304 stainless steel (AISI 304) – excellent corrosion resistance, suitable for indoor and outdoor use, including humid or chemical environments.
- Thickness: 3mm base metal thickness – provides high strength and rigidity for heavy-duty applications.
- Opening Size: 10mm x 20mm diamond (long way of diamond = 20mm, short way = 10mm) – balances material strength with open area for ventilation, light transmission, or drainage.
- Sheet Dimensions: 4ft x 8ft (1220mm x 2440mm) – standard size for easy handling and installation; custom sizes available upon request.
- Surface Finish: Mill finish – natural stainless steel surface, uncoated, suitable for painting or further processing, or left as-is for a clean industrial look.
- Strand Configuration: Uniform diamond pattern with consistent strand width and thickness; no sharp edges, safe to handle.
- Manufacturing Process: Expanded from a solid sheet by slitting and stretching – no joints, no welds, monolithic structure for maximum strength.

Key Advantages & Benefits for Customers
- Durability & Longevity: 304 stainless steel resists rust, corrosion, and oxidation, even in harsh environments. Ideal for outdoor fences, machine guards, and chemical plant flooring.
- High Strength-to-Weight Ratio: The 3mm thick base combined with the diamond pattern provides exceptional rigidity while keeping the sheet lightweight and easy to install.
- Versatile Applications: Suitable for architectural facades, walkway grating, ventilation panels, filtration screens, animal cages, and security barriers.
- Easy Fabrication: Can be cut, welded, bent, or painted without compromising structural integrity. Mill finish allows for custom coatings or left as-is for a professional look.
- Uniform Openings: Consistent diamond shape ensures predictable airflow, light passage, and particle retention – critical for filter screens and safety enclosures.
- Cost-Effective: Expanded metal is more economical than perforated sheet or woven wire mesh for similar strength requirements, and its long service life reduces replacement costs.
- Slip Resistance: The raised diamond pattern provides excellent traction underfoot, making it a safe choice for walkways and platforms.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between expanded metal and welded wire mesh?
A: Expanded metal is made from a single sheet of metal that is slit and stretched, creating a monolithic structure with no joints. Welded wire mesh is made by welding individual wires together. Expanded metal is generally stronger per unit weight and has no welding points that could fail, making it ideal for heavy-duty applications. -
Q: Can this mesh be used outdoors in coastal areas?
A: Yes, 304 stainless steel offers good resistance to saltwater and humidity, but for extreme coastal environments, we recommend 316 stainless steel. Please contact us for 316 options if needed. -
Q: Are the edges of the sheet smooth or sharp?
A: The edges are as-cut from the expansion process. They are not sharp like knife edges, but we recommend wearing gloves when handling. Custom edge finishing (e.g., trimmed or deburred) is available upon request. -
Q: What is the open area percentage of this 10x20mm diamond opening?
A: Typically, with a 3mm base thickness, the open area is approximately 60-65%. Exact percentage depends on the strand width, which can be customized. We can provide a detailed calculation for your specific order. -
Q: Can you supply smaller sheets or cut-to-size pieces?
A: Yes, we can cut the 4x8ft sheets to your required dimensions. Custom sizes are available with a minimum order quantity. Please inquire for details. -
Q: What is the weight of one sheet?
A: The approximate weight is 8.5 kg per 4x8ft sheet, but this may vary slightly with strand width. We can provide exact weight upon order confirmation. -
Q: Do you provide samples before bulk order?
A: Yes, we offer free samples (you pay shipping) for quality evaluation. Standard sample sizes are 200x200mm. Contact our sales team to request samples. -
Q: Is this product suitable for food processing equipment?
A: Yes, 304 stainless steel is food-grade and non-reactive. However, the mill finish may require additional cleaning. If you need a polished finish for easy cleaning, we can arrange a brushed or 2B finish upon request.
