Black wire, technically known as annealed wire, is the backbone of many industries dependent on fasteners and metal mesh weaving. The 1.5mm black wire introduced here is the result of research and development by our engineers to meet the specific needs of the Iranian domestic market. This product is manufactured using modern technology and by utilizing high-quality steel sheet edges. At first glance, the use of sheet edges might suggest a reduction in quality to some, but the engineering reality is quite different. The sheet edges, which are essentially part of the main body of steel sheets, possess exactly the same chemical properties and tensile strength standards as the main sheets. Our production process includes precision rolling followed by annealing heat treatment under a controlled atmosphere. This process ensures that the 1.5mm wire produced has the necessary softness for bending and weaving, while maintaining its structural strength for the production of various types of mesh. The final price of this wire, due to the intelligent use of this raw material source, is significantly lower than wire derived from imported or expensive ingots. This is a strategic advantage for mesh producers working with competitive profit margins. With a precise diameter of 1.5mm, this product meets the necessary standards for automatic and semi-automatic mesh weaving machines and minimizes machine downtime caused by wire breakage or warping. If you are looking for a product that adheres to quality while managing your final production costs and is readily available in high tonnages, this black wire will be your first choice. Relying on technical knowledge and market insight, we have launched a product developed in line with the real needs of domestic industrialists.
Quick Insight: The 1.5mm black wire produced from steel sheet edges is an engineered and economical product that optimizes mesh production costs in the domestic market with high quality and excellent flexibility.
A technical review of the 1.5mm black wire requires a detailed look at the production cycle from raw material to the final product. In this section, we examine the various engineering and metallurgical dimensions of this product to better understand its position in the mesh weaving value chain.
Before the annealing stage, 1.5mm wire has high internal stresses due to the cold drawing process, making it brittle and hard. The annealing heat treatment, performed in specialized furnaces, readjusts the steel grain structure. According to metallurgical standards published in specialized steel industry journals, this process increases the percentage of elongation of the wire, resulting in the desired softness for the mesh weaving process.
Producing 1.5mm wire from sheet edges requires high precision in drawing machines. A 1.5mm diameter is a widely used standard for the production of chain-link and various other fences. A deviation from this diameter, even by a few hundredths of a millimeter, can cause the wire to get stuck in automatic weaving machines. Our process, with real-time quality control, keeps dimensional tolerance to a negligible level so that mesh producers have no concerns about interruptions in the production line.
Quick Insight: Precise heat treatment (annealing) combined with high dimensional accuracy has created a balance between softness for easy weaving and structural resistance for the strength of the final mesh.
For mesh producers, the cost of raw materials is the most important factor in determining the final price. The use of our 1.5mm black wire allows producers to earn more profit at the same selling price as competitors, or to gain more market share by reducing prices. This product is an intelligent choice for the production of various types of crimped, welded, and chain-link meshes because its tensile strength is fully standardized and approved for withstanding environmental pressures.
Quick Insight: 1.5mm black wire directly increases the profit margin of mesh producers by optimizing raw material costs and reducing the waste rate in weaving machines.
This product is produced from the remaining edges of industrial steel sheets, which possess the same chemical properties as the main sheet and are considered valuable scrap only due to their appearance; they are recycled and converted into wire at a lower cost.
Yes, a 1.5mm diameter is one of the standard and widely used diameters for producing various types of chain-link fencing, offering a good balance between weight, strength, and price.
Black (annealed) wire lacks a zinc coating and is excellent and economical for applications that are not exposed to severe humidity or are intended to be painted or hot-dip galvanized after weaving.
Yes, the annealing process increases the softness of the wire, but its tensile strength is fully standardized and sufficient for mesh weaving applications.
Our products are supplied in standard coils with specific weights to ensure ease of transport and use for producers in workshops.
