Mesh Terminology and Specifications

The document defines key terms related to expanded metal mesh: LW (Long Way of Mesh), SW (Short Way of Mesh), w (Strand Width), t (Strand Thickness), and Ø (Approximate Hole Diameter). It distinguishes between flattened (ST) and non-flattened (T) round hole expanded mesh.

Mesh dimensions and weights vary depending on material type and tolerances for thickness, strand width, and mesh dimensions, as specified by DIN 791 standards. Actual mesh sizes are shown with allowances for minor reproduction tolerances.

Material Types and Mesh Series

The document presents multiple mesh series identified by codes such as KD 100, TAU 10, RB 15, Deco 91, Village, Residence, Terrace, Office, and Palace. Each series includes specifications for steel and aluminum meshes.

Technical Data Tables

For each mesh series, tables provide the following key parameters:

• Mesh size in millimeters
• Weight per square meter for steel and aluminum (kg/m²)
• Approximate open area percentage
• Maximum width of sheet or coil available (mm)

The data allow comparison of mesh properties across materials and series, facilitating selection based on weight, openness, and size constraints.

Standards and Tolerances

The document references DIN 791 for material thickness and dimensional tolerances, ensuring quality and consistency in mesh production.

Summary of Critical Information

• Mesh Dimensions: Defined by LW, SW, strand width, thickness, and hole diameter.
• Material Variants: Steel and aluminum options with differing weights and open areas.
• Mesh Types: Flattened (ST) and non-flattened (T) round hole expanded meshes.
• Weight and Open Area: Provided per mesh type and material to guide application suitability.
• Maximum Sheet Width: Important for manufacturing and installation planning.
• Compliance: Meshes conform to DIN 791 tolerances for quality assurance.

Best Practices and Recommendations

When selecting mesh, consider the balance between open area and structural weight to meet application needs. Allow for manufacturing tolerances in dimensions and weight. Choose material (steel or aluminum) based on environmental exposure and strength requirements.
