Expanded Metal Mesh

Standards for Expanded Metal Mesh

Expanded metal mesh is manufactured and tested according to several international standards, which ensure uniformity, quality, and safety. Common standards include:

• ASTM Standards (USA)

1. ASTM F1267: Standard Specification for Expanded Metal, Steel, and Stainless Steel.
2. ASTM A1011/A1018: Hot-rolled steel sheet standard used as raw material.
3. ASTM A240/A666: Stainless steel sheet/coil for expanded mesh.

• EN Standards (Europe)

1. EN 13236: Expanded metal for non-structural and decorative applications.
2. EN 10088-2: Stainless steel grades specification.

• JIS Standards (Japan)

1. JIS G 3302 / G 4313: Cold-rolled steel sheet and stainless steel specifications.

• ISO Standards

1. ISO 9044: For expanded metal mesh used in filtration and industrial applications.

Grades for Expanded Metal Mesh

The grade depends on the material used and its application. Common grades include:

• Carbon Steel

1. Grade: Low, Medium, and High Carbon Steel (e.g., ASTM A36, EN 10025 S235JR)
2. Properties: High strength, moderate corrosion resistance (can be galvanized for better protection)
3. Applications: Walkways, fencing, platforms, and industrial grating.

• Stainless Steel
  

  Common Grades:

1. 304 / 1.4301: General-purpose stainless steel, corrosion-resistant, ideal for indoor/outdoor use.
2. 316 / 1.4401: High corrosion resistance, suitable for marine or chemical environments.
3. 316L / 1.4404: Low-carbon variant for welding and extreme corrosion resistance.
4. Applications: Food processing, chemical plants, architectural panels, and decorative cladding.

• Aluminum

1. Grades: 1050, 3003, 5005
2. Properties: Lightweight, corrosion-resistant, good electrical conductivity.
3. Applications: Decorative panels, lightweight grating, ventilation.

• Alloy Steel (Specialized)

1. Grades: Varies based on mechanical requirements (e.g., chromium-molybdenum alloys)
2. Applications: High-strength industrial platforms, heavy load-bearing grating.
