Black wire, known among engineers and contractors of construction projects as annealed wire, plays a vital role in structural connections. Our 2.0mm black wire is produced with a special focus on operational needs in construction workshops. The main differentiator of this product lies in the raw material sourcing process. This wire is produced from high-quality steel sheet edges. This supply strategy, while maintaining all mechanical and chemical standards required for construction connections, has made it possible to offer a very economical and competitive product for the domestic market. In rebar tying projects, work speed and the flexibility of the wire are of great importance. Our 2.0mm black wire is produced under precise heat treatment in modern annealing furnaces to achieve maximum softness and ductility. This feature allows rebar workers to create strong and reliable knots at high speed. In addition to rebar tying, this wire is an excellent option for binding concrete forms (formwork), where maintaining stability and resistance against concrete pressure is important. By choosing this wire, you bring a product to your workshop that, in addition to reducing raw material procurement costs, minimizes workshop waste due to its high flexibility. Relying on our industrial experience and precise knowledge of harsh construction environments, we have optimized this product to be economical while possessing the strength to withstand loads in concrete structures. This wire is an engineered solution for those seeking a balance between quality, price, and efficiency in building skeleton execution.
Quick Insight: 2.0mm black wire produced from sheet edges, utilizing advanced annealing operations, is an ultra-soft, flexible, and economical solution to speed up rebar tying and formwork processes in construction projects.
A technical review of 2.0mm black wire for construction applications requires a proper understanding of its metallurgical properties and mechanical behavior in civil engineering environments. This product, with a precise diameter of 2.0mm, is recognized as an accepted standard in structural connections.
The annealing process is the beating heart of this product's quality. In this process, the wire is placed under controlled heat in a furnace after the cold drawing stage. According to results from reputable metallurgical laboratories, this action eliminates internal stresses caused by cold deformation and restores the steel microstructure to a homogeneous and soft state. For rebar tying, this softness means excellent knotting; the wire can easily be wrapped around rebar without breaking in the worker's hands.
Although this wire is prepared from steel sheet edges, its chemical structure fully complies with building construction standards. The tensile strength of this wire is fully optimized to withstand the pressures exerted during concrete pouring and vibrator vibrations. This product is engineered in such a way that, while soft, it shows sufficient resistance against cutting or loosening of knots under pressure.
Quick Insight: The annealing process causes extraordinary softness for easy knotting, and the use of standard sheet edges ensures sufficient strength to withstand construction loads and concrete pressure.
In large construction projects, indirect costs caused by slow workers or wire waste can be significant. Our 2.0mm black wire, due to its appropriate weight and high flexibility, increases the speed of rebar tying execution. Furthermore, purchasing economical wire improves the profit margin of contractors in project tenders.
This product is not limited to rebar tying. In the formwork section, the use of black wire for binding the backing of metal or wooden forms has wide application. The softness of this wire allows formworkers to easily fix and tighten the forms in their precise position. The high durability of this product in binding forms minimizes the risk of form bulging during concrete pouring.
Quick Insight: By significantly reducing waste and increasing the speed of knotting for rebar workers, as well as providing high stability in binding forms, this wire acts as a strategic tool in cost management for civil projects.
Due to creating a balance between the holding power of the rebar and ease of knotting with pliers, this diameter is known as the most standard and widely used size in the Iranian construction market.
Yes, sheet edges are part of the main body of industrial-quality steel sheets. After undergoing drawing and annealing operations, the resulting wire possesses all the mechanical features necessary for structural connections, and there are no safety concerns.
Black (annealed) wire lacks a zinc protective layer and is perfectly suitable and much more economical than galvanized wire for use inside concrete structures (where it is not directly exposed to air).
No, thanks to the correct annealing process, the wire has high elongation (flexibility), which prevents it from breaking easily when tightening knots with pliers or a formwork wrench.
