Galvanized Steel Wire and Cold Drawn Steel Wire are mainstream types of Construction Steel Wire. Manufactured from high-quality carbon steel wire rods through pickling, phosphating, multi-pass cold drawing and professional anti-rust treatment, these metal wires feature uniform strength, excellent toughness, fracture resistance, superior flexibility and outstanding corrosion resistance. With complete specifications and versatile performance, they are essential basic materials for construction binding, wire mesh weaving, engineering reinforcement, hardware processing, agricultural and forestry protection projects.
1. Core Material Grades & Complete Parameters
All our steel wires are made of national standard high-quality carbon structural steel with high purity and low impurity content, delivering stable mechanical performance and complying with both domestic engineering and international export standards. The mainstream applicable material grades are as follows:
Q195: Features soft state, high toughness and excellent plasticity with easy bending and welding performance without cracking. It is the most widely used general material on the market, mainly applied to Construction Steel Wire, binding wire and ordinary woven mesh.
Q235: Possesses higher strength and moderate hardness than Q195 with better tensile properties. It is suitable for high-strength binding, fence mesh, gabion mesh and structural reinforcement scenarios for Cold Drawn Steel Wire and Galvanized Steel Wire.
45# High Carbon Steel: Boasts high tensile strength, high hardness, wear resistance and stretch resistance, specially used for high-strength spring wire, rope wire, precision hardware and mechanical accessories.
60#/70# High Carbon Steel Wire: Ultra-high strength grade, applicable to high-end working conditions such as prestressed accessories, special industrial wire drawing and high-strength filter screens.
Import/Export Special Material: SAE1006, SAE1008, fully compliant with European and American foreign trade standards, specially customized for overseas export orders of Galvanized Steel Wire and Construction Steel Wire.
2. Product Classification & Production Technology
2.1 Cold Drawn Steel Wire (Black Wire)
Cold Drawn Steel Wire adopts Q195/Q235 high-quality wire rod as the base material, formed by precision multi-pass cold drawing at room temperature. It has dense grain structure, smooth surface, accurate dimensions and stable tensile strength. With no surface coating and high cost performance, it is the most widely used general Construction Steel Wire in engineering projects. It is mainly used for steel bar binding, wall tie construction, scaffold binding, ordinary wire mesh weaving and packaging binding on construction sites. It can be divided into Q195 soft wire, Q235 hard wire and 45# high-strength cold drawn wire according to different materials.
2.2 Galvanized Steel Wire (Anti-rust & Anti-corrosion Wire)
Galvanized Steel Wire is processed by hot-dip galvanizing or electro-galvanizing on the basis of refined cold drawn wire. The uniform and firm zinc layer isolates air and moisture, providing excellent anti-rust and anti-corrosion ability and superior weather resistance, suitable for long-term service in outdoor, humid, coastal and highly corrosive environments.
Classified by production process:
Electro-galvanized Steel Wire (Cold Galvanized): Bright and flat surface with fine and smooth zinc layer, ideal for scenarios with high appearance requirements, indoor use and short-term outdoor use.
Hot-dip Galvanized Steel Wire (Hot Galvanized): Thick zinc layer with strong adhesion and long anti-corrosion service life, serving as the preferred Construction Steel Wire for outdoor engineering, marine environment and long-term protection projects.
Mainstream material grades: Q195, Q235, SAE1006, SAE1008. All material types support customized galvanizing treatment.
3. Executive Standards
Domestic Standards: GB/T 343-2012 Low Carbon Steel Wire for General Purposes, GB/T 15393 Zinc Coating on Steel Wire
International Standards: ASTM A510, BS, DIN, JIS. We can produce SAE1006/SAE1008 foreign trade grade products to meet global project acceptance requirements.
4. Specification Parameters
Wire Diameter Range: 0.3mm – 6.0mm
Conventional Stock Sizes: 0.5mm, 0.8mm, 1.0mm, 1.2mm, 1.6mm, 2.0mm, 2.5mm, 3.0mm, 4.0mm, 5.0mm
Delivery Forms: Large-coil wire, spooled wire, custom fixed-length straight cut wire
Appearance Quality:Cold Drawn Steel Wire features smooth surface without cracks, burrs and rust; Galvanized Steel Wire has complete zinc layer without missing plating and peeling with uniform color. The dimensional tolerance of all Construction Steel Wire is strictly controlled.
5. Material-based Mechanical Properties
Q195 Cold Drawn Steel Wire: Tensile strength 400–600MPa, high toughness and easy bending, specially suitable for binding work
Q235 Cold Drawn Steel Wire: Tensile strength 600–800MPa, higher hardness and strong bearing capacity
45#/70# High Carbon Steel Wire: Tensile strength 800–1200MPa, high strength, wear resistance and anti-deformation performance
Galvanized Steel Wire retains the complete mechanical properties of the base cold drawn wire, and the zinc layer will not affect the structural strength. With long-term anti-rust performance and qualified salt spray test results, its outdoor service life is far longer than ordinary Cold Drawn Steel Wire.
6. Main Application Fields
1. Construction Engineering: Steel bar binding, wall tie fixing, scaffold binding and concrete component fixing. Construction Steel Wire is an essential consumable for construction sites.
2. Wire Mesh Products: Used as core raw materials for welding mesh, gabion mesh, fence mesh, barbed wire, window screen and protective mesh weaving, mainly adopting Cold Drawn Steel Wire and Galvanized Steel Wire.
3. Municipal & Landscape Engineering: Seedling fixing, river protection, slope protection and road guardrail production.
4. Hardware Products: Manufacturing of rigging, hooks, metal crafts and mechanical accessories.
5. Agricultural, Forestry & Outdoor Projects: Breeding fence, farmland protection, vine traction and coastal anti-corrosion engineering, with Galvanized Steel Wire as the preferred material.
7. Core Product Advantages
1. Complete Material Grades: Multiple optional materials including Q195, Q235, 45#, SAE1006 and SAE1008, fully meeting civil, industrial and foreign trade procurement demands.
2. Stable Performance: Adopting formal wire rod raw materials and mature production technology, each batch of Cold Drawn Steel Wire has unified strength and toughness without wire breakage and disorder.
3. Corrosion Resistance & Durability: The zinc layer of Galvanized Steel Wire has strong adhesion, resisting wind, rain and moisture erosion with long outdoor service life.
4. Excellent Machinability: Flexible and easy to bend, cut and weld, compatible with manual operation and full-automatic mechanical processing.
5. High Cost Performance: Sufficient stock of full specifications and stable mass production supply, serving as high-cost-effective Construction Steel Wire for various projects.
8. Packaging, Transportation & Delivery Cycle
