Product Features and Benefits
- Superior Corrosion Resistance: The hot-dip galvanized coating provides a sacrificial layer, effectively protecting the DX51 carbon steel base from rust and oxidation. This makes the mesh ideal for humid environments, outdoor installations, and chemical exposure areas.
- Structural Strength and Rigidity: By converting the solid steel sheet into a diamond pattern without removing material, the structural integrity of the original sheet is retained. The 2mm strand width provides robust impact resistance while remaining lightweight for easy handling.
- Excellent Ventilation and Visibility: The 12mm x 30mm diamond openings allow for free air circulation, light transmission, and visual transparency while still acting as a security barrier. This feature is highly valued in ventilation systems, machine guards, and animal cages.
- Slip-Resistant Surface: The raised, rigid diamond mesh pattern creates a natural slip-resistant walking surface when used as floor decking or walkway treads, enhancing workplace safety.
- Ease of Fabrication: The galvanized layer adheres well to the base metal, allowing the sheet to be cut, bent, stamped, or welded without significant coating peeling, provided proper tools are used.
- Cost-Effective Long-Term Solution: Galvanizing is one of the most economical methods for protecting steel. This product requires minimal maintenance over its service life, reducing lifecycle costs compared to painted alternatives.
Technical Advantages of DX51 Steel
The DX51 grade is a low-carbon steel specifically designed for cold forming and subsequent metallic coatings. Our raw coils are sourced from reputable mills, ensuring consistent surface quality before processing. During the expand process, the material's high malleability prevents cracking at the diamond apexes, which is critical for maintaining structural continuity. Additionally, the zinc-iron alloy layer formed during galvanizing enhances abrasion resistance, making the sheet suitable for applications involving foot traffic or friction from material handling.
Primary Application Areas
- Architectural & Decorative: Façade cladding, sunshades, ceiling panels, partitions, and decorative screening for modern building designs.
- Security & Protection: Window guards, fencing, mesh enclosures, machine safety guards, and partitions in commercial and industrial facilities.
- Ventilation & Filtration: Ventilators, air intake filters, grilles, and radiator protection in HVAC systems.
- Walkways & Gratings: Stair treads, catwalks, mezzanine flooring, and anti-slip platforms.
- Agriculture & Husbandry: Poultry cages, animal pens, greenhouse support racks, and seed drying trays.
- Transportation & Storage: Truck grilles, heavy-duty shelving, pallets, and protective baskets.

Frequently Asked Questions
Q: What does the diamond opening size 12mm x 30mm mean?
A: It refers to the dimensions of the diamond-shaped aperture. The shorter diagonal (SWO) measures 12mm, and the longer diagonal (LWO) measures 30mm. This configuration balances particle retention with high open area.
Q: What exactly does steel grade DX51 indicate?
A: DX51 is a designation used in the European standard system (EN 10142/EN 10346) for continuously hot-dip coated steel. It refers to steel with a minimum yield strength of 140-260 MPa, commonly used for general construction and cold forming.
Q: Is this product suitable for outdoor use?
A: The hot-dip galvanized finish provides substantial weather resistance, making it appropriate for most outdoor environments. However, the level of protection can be enhanced with a higher zinc coating weight. We recommend specifying a heavier zinc coating if installation is in coastal or highly corrosive industrial areas.
Q: What is the difference between strand width and sheet thickness?
A: In expanded metal manufacturing, the strand width refers to the width of the steel that has been stretched, which typically corresponds to the original sheet's thickness. In this product, the strand width is 2mm, incurring a result where the metal is 2mm thick.
Q: Can I request custom sheet sizes?
A: Yes. We can cut the expanded mesh to your exact length and width specifications. Additionally, custom shapes such as discs or triangles, and pre-bending into angles can be performed during production.
Q: How does galvanized expanded metal compare to welded mesh?
A: Because expanded metal is formed from a solid sheet, it will not unravel or separate at the joints like welded wire mesh could. This makes it more secure, often preferred for security guards and heavy-duty fencing. Additionally, expanded metal offers a high strength-to-weight ratio and a characteristic diamond pattern that provides slip resistance.
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 100 sheets, but we are prepared to accept smaller trial orders to evaluate product quality. For larger projects, we can offer tiered pricing and shorter production lead times.
Q: What kind of packaging ensures the mesh is not damaged during transport?
A: The sheets are packed in bundles with wooden pallets, protected by waterproof paper and steel strapping. Special edge protectors are used to prevent zinc coating scratches during the long sea voyage. Cartons are only used for very small sample shipments.
