Whether you need standard mesh for industrial use or custom-designed panels for building facades, we provide full-service solutions from design to delivery as a reliable expanded metal mesh facade supplier.
What Is Stainless Steel Flattened Expanded Metal?
Stainless steel flattened expanded metal is a processed metal mesh made by first expanding standard stainless steel sheet or plate into diamond-shaped openings, then passing the mesh through precision rolling mills to flatten the raised strands into a smooth, uniform surface. Unlike standard raised expanded metal, the flattened version offers a sleek profile, consistent thickness, and enhanced usability for both functional and decorative applications.
The flattening process removes the three-dimensional raised structure, creating a flat, even surface that is safe to touch, easy to clean, and ideal for applications where a smooth finish is required. It retains the high strength and corrosion resistance of stainless steel while improving aesthetics and practicality.
We produce flattened expanded metal using high-quality 304 and 316 stainless steel, ensuring the final product maintains excellent mechanical properties and long-term durability. Our advanced production lines guarantee precise diamond openings, uniform strand width, and a burr-free smooth surface for every panel we manufacture.
Material Grades for Stainless Steel Flattened Expanded Metal
We use premium food-grade and industrial-grade stainless steel to manufacture flattened expanded metal, offering different grades to meet various environmental and performance requirements. The choice of material grade directly affects corrosion resistance, service life, and application suitability.
| Material Grade | Key Features | Recommended Applications |
|---|---|---|
| 304 Stainless Steel | General corrosion resistance, cost-effective, good formability | Indoor architecture, machinery guards, general filtration |
| 316 Stainless Steel | Marine-grade, chemical-resistant, high durability | Coastal projects, outdoor facades, marine equipment |
| 316L Stainless Steel | Low-carbon, weldable, maximum corrosion resistance | Food processing, medical equipment, harsh environments |
304 stainless steel is the most commonly used material for flattened expanded metal due to its balanced performance and affordability. For outdoor, coastal, or high-corrosion environments, we strongly recommend 316 stainless steel to ensure long service life and minimal maintenance.
Manufacturing Process of Flattened Expanded Metal
The production of stainless steel flattened expanded metal involves two core processes: expanding and flattening. Our fully automated production lines ensure high precision, consistency, and efficiency throughout the manufacturing cycle.
- Raw material selection: High-quality 304/316 stainless steel sheet
- Slitting: Cutting stainless steel sheets into proper widths for expanding
- Expanding: Using hydraulic expanders to form diamond-shaped openings
- Flattening: Passing through precision rollers to create a smooth flat surface
- Straightening & leveling: Ensuring flatness and dimensional accuracy
- Cutting: Trimming to custom or standard panel sizes
- Surface treatment: Deburring, passivation, or polishing as required
- Quality inspection & packaging before shipment
The flattening step is critical: it compresses the raised strands evenly without damaging the diamond structure, resulting in a mesh that is both strong and smooth. Our strict process control ensures no cracks, deformations, or dimensional deviations in the finished product.
Specifications & Dimensions
We offer stainless steel flattened expanded metal in a full range of standard specifications, with fully customizable options available for special projects. The key specifications include strand width, diamond opening size, sheet thickness, and panel dimensions.
Standard Specifications
- Material Thickness: 0.5mm – 6.0mm
- Strand Width: 1.0mm – 10.0mm
- Diamond Opening: 3mm × 6mm up to 50mm × 100mm
- Standard Panel Size: 1000mm × 2000mm, 1220mm × 2440mm
- Custom Sizes: Available upon request
Small opening flattened expanded metal is widely used in precision filtration and safety guards, while large opening versions are popular for architectural facades and sunscreens. Our small hole expanded metal mesh is a top choice for clients needing high accuracy and fine filtration performance.
Surface Finishes & Treatments
Stainless steel flattened expanded metal can be processed with various surface finishes to enhance aesthetics, corrosion resistance, and cleanability. We provide standard and custom surface treatments to match your project requirements.
- Mill Finish: Natural metallic surface, cost-effective for industrial use
- Brushed Finish: Uniform matte lines, modern architectural appearance
- Passivated Finish: Improved corrosion resistance, no discoloration
- Mirror Polish: High-gloss finish for luxury decorative applications
- Sandblasted Finish: Non-reflective matte surface for industrial equipment
The smooth surface of flattened expanded metal makes it ideal for surface finishing processes. Brushed and passivated finishes are the most popular choices for architectural and outdoor applications, combining beauty and durability.
Key Advantages of Stainless Steel Flattened Expanded Metal
Stainless steel flattened expanded metal offers a unique combination of structural, functional, and aesthetic benefits that make it superior to other mesh products. Its advantages make it suitable for a wide range of demanding applications.
- Smooth & Safe Surface: No raised edges, safe for handling and contact
- High Strength-to-Weight Ratio: Lightweight but extremely durable
- Excellent Corrosion Resistance: Stainless steel material prevents rust
- Uniform Appearance: Consistent diamond pattern for visual appeal
- Easy to Clean & Maintain: Smooth surface resists dust and dirt buildup
- 100% Material Utilization: No scrap during production, eco-friendly
