Stainless Steel Square Hole Mesh China Factory

Stainless Steel Square Hole Mesh

Anping CREMOTIVE Wire Mesh Products CO., LTD presents its Stainless Steel Square Hole Mesh, engineered for applications requiring uniform square apertures and robust mechanical performance. Square hole mesh is typically produced by weaving or welding intersecting wires at equal intervals in both warp and weft directions, forming consistent square openings. This design allows predictable fluid flow, reliable particle retention, and structural integrity across a variety of industrial, architectural, and environmental uses.

Materials and Fabrication Methods

• Grade Selection:

• 304 Stainless Steel: Offers good general corrosion resistance and formability, used where chemical aggressiveness is moderate.

• 316L Stainless Steel: Preferred for marine, chemical, and high-chloride environments due to enhanced pitting resistance and improved weld zone stability.

• Weaving versus Welding:

• Woven Square Hole Mesh: Created on specialized looms, weaving fine wires into orthogonal patterns. Over-under interlacing of warp and weft wires forms tight junctions without welding. This process produces flexible rolls that can be bent or curved for seamless installation in filter housings or architectural panels.

• Welded Square Hole Mesh: Heavier gauge wires run orthogonally and are spot-welded at each intersection, yielding a rigid panel ideal for heavy-duty screening, reinforcement, and fencing. Welded mesh exhibits minimal elongation under load and maintains aperture geometry even under impact or vibration.

• Finish Treatments: After weaving or welding, mesh panels undergo thorough pickling and passivation. Pickling dissolves embedded iron and impurities, while passivation restores a protective chromium-oxide layer. Optional electropolishing produces a bright, smooth surface that resists staining and easily sheds contaminants during cleaning.

Performance Attributes

• Uniform Square Openings: Apertures commonly range from 0.5 mm × 0.5 mm up to 20 mm × 20 mm; tolerance typically held within ±5 % for woven mesh and ±2 % for welded mesh. Consistent opening sizes ensure reliable screening thresholds and pressure-drop predictions.

• Open-Area Ratios: Depending on wire diameter and aperture size, open area ranges from 10 % to 60 %. Higher open areas maximize fluid throughput, essential for high-capacity filtration or ventilation applications.

• Mechanical Strength:

• Woven Mesh: Provides flexibility to conform to cylindrical or curved housing geometries without compromising aperture integrity. When laminated or layered, woven mesh can achieve multi-stage filtration gradients.

• Welded Mesh: Resists heavy loads and abrasive impact, preferred in aggregate screening, security barriers, and structural reinforcement.

• Corrosion and Temperature Resistance: Both 304 and 316L alloys operate continuously at temperatures up to 400 °C (750 °F). The stainless steel composition resists rust, scale, and chemical attack, making square hole mesh suitable for harsh environments, including chemical processing, oil refining, and coastal installations.

Common Applications

• Industrial Screening and Filtration:

• Aggregate and Mineral Processing: Large-aperture welded mesh grades (e.g., 10 mm × 10 mm) screen gravel, sand, and slags.

• Food-Grade Sieving: Fine woven mesh (e.g., 0.5 mm × 0.5 mm) separates grains, spices, and milled powders, meeting sanitary standards after passivation and electropolishing.

• Water Treatment: Prefiltration screens to remove leaves, twigs, and coarse debris in intake channels.

• Architectural and Decorative Uses:

• Façade Cladding and Sunshades: Woven square hole mesh panels provide an appealing geometric pattern while shading façades from direct sunlight and facilitating natural ventilation.

• Interior Design Elements: Mesh partitions, balustrades, and ceiling baffles combine aesthetic versatility with structural support. Available in polished or brushed finishes to coordinate with modern material palettes.

• Security and Reinforcement:

• Fencing and Cage Construction: Welded square mesh resists cutting and deformation, used in perimeter fencing, protective enclosures, and machine guards.

• Reinforced Composite Panels: Embedded within concrete or polymer composites to enhance tensile strength and crack resistance.

Customization and Quality Assurance
Anping CREMOTIVE offers square hole mesh in roll widths up to 2 m and sheet panels up to 6 m × 2 m. Woven mesh counts (warp × weft) range from 10 × 10 wires per inch to 200 × 200 wires per inch. Welded mesh wire gauges vary from 2 mm to 10 mm in diameter. Edging services—such as folded hems, welded frames, and welded support ribs—are available to facilitate installation and prevent edge fraying.

Every mesh lot undergoes comprehensive inspections:

• Dimensional Verification: Optical image analysis confirms wire diameter and aperture size within specified tolerances.

• Mechanical Testing: Tensile tests on warp/weft bundles verify compliance with minimum strength requirements.

• Surface Quality Checks: Visual and microscopic inspection ensure no residual mill scale, weld spatter, or pinholes remain.

Certificates of Conformity accompany each shipment, documenting material grade (per ASTM A240/316L), weave specification, slot tolerance, and finish treatment. Through rigorous manufacturing controls, Anping CREMOTIVE Wire Mesh Products CO., LTD delivers stainless steel square hole mesh that precisely meets customer requirements for performance, durability, and consistency.
