Steel wire industry

Galvanized steel wire is a common material in construction and other industry, and standardization of its quality and performance is particularly important.  This article will delve into the standards for galvanized steel wire.

Galvanizing treatment can effectively prevent corrosion of steel wire and improve its weather resistance and durability.  At the same time, galvanized steel wire also has good mechanical properties and plastic deformation ability, and is widely used in construction, agriculture, transportation and other fields.

Galvanized steel wire is divided into several standard classifications based on different uses and requirements.  Common classifications include: galvanized steel wire for construction, galvanized steel wire for agriculture, galvanized steel wire for transportation, etc.  Each classification has corresponding standard specifications to ensure safe and reliable application of galvanized steel wire in different fields.

In order to ensure quality and performance of galvanized steel wire, various countries and regions have formulated corresponding standard requirements.  These requirements mainly include: thickness of zinc coating, adhesion,corrosion resistance, mechanical properties, etc.  The standard requirements are formulated to improve quality and reliability of galvanized steel wire and ensure its service life in different environments.

Domestic and international standards for galvanized steel wire cover different aspects of steel wire, such as material composition, physical properties, chemical properties, etc.  The standards for galvanized steel wire usually include the following:

GB/T 343-2006 "General Purpose Low Carbon Steel Wire": This standard specifies the technical requirements, test methods, inspection rules and markings, packaging, transportation and storage of general purpose low carbon steel wire;

GB/T3248 "Galvanized Steel Wire for Overhead Stranded Wires" specifies the materials, surface quality, diameter and diameter deviation, length and length deviation of galvanized steel wires with a single wire nominal diameter (including coating) ranging from 1.25mm to 5.50mm.  Joints, sampling, test locations, mechanical performance tests, zinc coating tests, certificates, etc.  This standard applies to galvanized steel wires for overhead stranded structures and/or reinforcements;

ASTM A641/A641M-19 "Standard Specification for Zinc-Coated (Galvanized) Carbon Steel Wire": This standard stipulates the requirements for galvanized carbon steel wire, including the quality, appearance, size, mechanical properties, etc. of zinc coating;

EN 10244-2 "Steel wire and wire products - Non-ferrous metallic coatings on steel wire - Part 2: Zinc or zinc alloy coatings": This standard specifies the requirements and test methods for non-ferrous metal coatings on the surface of steel wires, including zinc or zinc alloy coatings.  The quality, thickness, appearance, etc. of zinc alloy coating; 

JIS G 3547 "Zinc-coated steel wirestrands": This standard specifies requirements for galvanized steel wire strands, including the thickness, appearance, mechanical properties, etc. of zinc coating.

Among international standard classifications, ISO 16120-1 2001 involves steel products, such as steel pipes, cast iron pipes, steel wires, steel wire ropes, shaped steel, and special-shaped steel.  ISO 16120-1:2001 "Non-alloy steel wire products. Part 1: Fine round steel wire. Technical conditions": Mainly used to specify the manufacturing conditions of galvanized steel wire, and testing methods of various technical parameters; ISO 16120-2:  2011 "Non-alloy steel wire products. Part 2: Fine round steel wire. Mechanical properties": mainly refers to mechanical properties and other physical properties of steel wire; ISO 16120-3:2017 "Non-alloy steel wire products. Part 3: Fine round steel wire  "Surface chemical analysis": This standard is used to specify thickness of the galvanized layer of the steel wire, the structure of zinc coating, surface condition of zinc coating, etc.

These standards are formulated in different countries or regions to guide production and use of galvanized steel wire to ensure that its quality and performance meet requirements.  Strict compliance with galvanized steel wire standards is essential to ensure safety and quality in construction and industrial sectors.  Following standard operations can effectively prevent accidents and quality problems caused by material quality that does not meet requirements.  At the same time, standardized production and use will also help improve  overall competitiveness and sustainable development of galvanized steel wire industry.

In summary, galvanized steel wire standards play an important guiding role in the construction and industrial fields.  By adhering to standard requirements, quality and performance of galvanized steel wire are ensured for safe and reliable applications.
