Bulk Galvanized Diamond Wire Mesh Fencing Roll

This product consists of low‑carbon steel wire woven into a uniform hexagonal (diamond) opening, followed by a hot‑dip galvanizing process that deposits a zinc layer typically ranging from 55 g/m² to 275 g/m² depending on coating class. The roll format supplies continuous lengths that reduce field splicing and accelerate installation on perimeter security, agricultural containment, and industrial boundary projects.

Material & Construction

Wire diameter options range from 1.2 mm to 3.0 mm, selected based on required tensile strength and impact resistance. The mesh opening (distance between parallel wires) is commonly 50 mm, 75 mm, or 100 mm, providing a balance between visibility and barrier effectiveness. The zinc coating adheres to ASTM A123/A123M standards, delivering uniform coverage that protects the steel core in environments with moderate to high humidity.

Technical Specifications

Typical roll widths are 1.0 m, 1.2 m, and 1.5 m, with lengths customized to project needs—commonly 20 m, 50 m, or 100 m per roll. The tensile strength of the base wire falls between 350 MPa and 550 MPa, yielding a mesh breaking load that scales with wire diameter and opening size. Elastic modulus remains approximately 200 GPa, consistent with low‑carbon steel.

Parameter	Typical Range	Notes
Wire Diameter	1.2 mm – 3.0 mm	Selected per load requirement
Mesh Opening	50 mm – 100 mm	Aperture influences visibility and rigidity
Coating Weight	55 g/m² – 275 g/m²	ASTM A123 Class D to A
Roll Width	1.0 m – 1.5 m	Custom widths available
Roll Length	20 m – 100 m (custom)	Determined by handling constraints

Applications

In agricultural settings, the mesh prevents livestock ingress while allowing airflow and sunlight, reducing heat buildup compared to solid panels. For industrial perimeters, the diamond pattern provides climb resistance and clear visibility for surveillance cameras, supporting security protocols without creating blind spots. The galvanized finish extends service life in coastal or chemically exposed zones where untreated steel would suffer rapid rust propagation.

Quality Assurance

Each production lot undergoes dimensional verification of wire diameter and opening size using calibrated gauges, with tolerance typically ±0.05 mm for diameter and ±2 mm for opening. Coating thickness is measured via magnetic induction per ASTM A90/A90M, ensuring uniformity across the roll surface. Visual inspection checks for uniform weave, absence of broken wires, and consistent zinc adhesion before packaging.

Customization Options

Clients may specify alternative wire grades such as high‑tensile low‑alloy steel for increased load capacity, or select a PVC‑over‑galvanized coating for added UV resistance and color coding. Opening dimensions can be adjusted to meet specific animal containment or debris filtration requirements. Roll lengths are cut to match site logistics, minimizing waste and handling time.

Packaging & Shipping

Rolls are wrapped in UV‑stabilized polyethylene film, then placed on wooden pallets with edge protectors to prevent deformation during transit. For overseas shipments, desiccant packs are included to control moisture within the package, and pallets are secured with strapping that meets ISPM‑15 standards. Labels include product code, wire diameter, opening size, coating class, and total weight.

Frequently Asked Questions

Can the wire diameter and opening be customized for a specific load case?

Yes, both parameters are adjusted according to engineering calculations provided by the customer.

What information is required to obtain a quotation?

Required data include desired wire diameter, opening size, coating class, roll width, total length, and delivery destination.

How is the zinc coating quality verified?

Coating thickness is measured using non‑destructive magnetic induction tools on multiple points across each roll.

What packaging options are available for long‑distance transport?

Standard packaging includes polyethylene film and palletization; additional options such as corrugated cardboard sleeves or steel banding can be arranged.
