5 Reasons Why Quality Wire Mesh Requires Cold Drawn Wire ✔ Stronger and Higher Load Capacity The cold drawing process increases the wire’s strength and hardness. Cold drawn wire can use a smaller diameter while maintaining or exceeding the strength of larger conventional rebar/ wire, helping reduce costs. ✔ Precise and Consistent Grid Spacing Cold drawn wire has a consistent and accurate diameter, and it is welded using modern machinery, ensuring equal sheet and grid spacing according to engineering standards. Unlike to general rebar/ wire that may have higher dimensional variation, resulting in inconsistent grid spacing. ✔ Strong and Firm Welds with Certified Standards Manufactured using electrical resistance welding in factories, creating tight and durable weld joints. Better than manually tying reinforcing bars, providing greater strength and a cleaner appearance. ✔ Helps Reduce Concrete Cracking Our wire is manufactured and being certified by TIS 747-2564 and TIS 943-2564. Quality is reliable and can be inspected and verified. ✔ Easy Installation and Cost-Effective in the Long Run Suitable for concrete reinforcement, roads, parking lots, and structures requiring high durability. Helps reduce concrete cracking because the load is distributed evenly. Easy and fast installation, reducing construction time and labor costs compared to tying rebar individually. SIW Wire Mesh is manufactured to certified standards, delivering reliable performance for every project. 🏗️✨ Click >>HERE<< to See Our Product

⚠️ Clearing Up the ConfusionWhat’s the difference between Cold Drawn Wire VS Reinforcing Bar (Rebar) ? Here’s a simple breakdown you can understand in under 3 minutes:Cold Drawn WireCold Drawn Wire is produced by drawing steel through a die at room temperature, where the strength increases due to the strain hardening process. As a result, it offers precise dimensions and a smooth, shiny wire surface, making it suitable for applications such as:✔ Concrete Pipes✔ Stirrups✔ Spun Piles✔ Precast ConcreteReinforcing Bar (Rebar)Reinforcing Bar (Rebar) is manufactured by rolling steel with rollers at high temperatures (900–1200°C), allowing the metal to be easily shaped without cracking. However, its dimensional accuracy is lower compared to cold-drawn wire, and oxide scale forms on the surface, which must be removed after hot rolling. It is commonly used in applications such as:✔ Columns✔ Beams✔ Slabs📌 Quick SummaryIf the application focuses on strength, choose Cold Drawn Wire.If the application focuses on bonding with concrete and ductility, choose Reinforcing Bar (Rebar).
