- Ensures that IS 18513 standards are complied : The BIS certification standards and ascertain that the quality, strength, and reliability of ZAM coated steels conform to the criteria laid down in the Indian Standard IS 18513.
- Excellent in corrosion resistance :The ordinary ensures that the ZAM coated steel provides the best protection against corrosion in comparison to other ordinary coated galvanized steel.
- Specifies Coating Composition and Thickness:The International Standard IS 18513 defines coating mass, chemical composition, and thickness of Zinc-Aluminium-Magnesium coating for long-lasting durability.
- Ensures mechanical strength and performance :BIS certification of steel ensures the steel meets the necessary mechanical requirements such as tensile strength, flexibility, and formability.
- Necessary Market Approval and Consumer Trust: BIS certification gives the manufacturers the right to use the BIS standard mark, which in turn helps the manufacturers meet legal requirements, enhance the credibility and hence the acceptability of their products in the domestic and global market.
Introduction
BIS certification for ZAM (Zinc-Aluminium-Magnesium) coated steel under IS 18513 ensures that quality, safety, and performance requirements specified by the Bureau of Indian Standards are met by a steel product. ZAM coated steel currently has a wide range of applications in construction, infrastructure, automobiles, solar structures, etc., because of its excellent corrosion-resistant properties and long product life. The requirements for coating composition, coating mass, and mechanical properties, along with tests that ensure the above requirements and norms with regard to durability and reliability, are specified under IS 18513.
What is IS 18513?
IS 18513 is the Indian Standard issued by the Bureau of Indian Standards – BIS that prescribes the requirements for Zinc-Aluminium-Magnesium coated steel flat products. This standard ensures that the coated steel meets defined quality, durability, and performance criteria for various industrial and structural applications.
Key Points:
- IS 18513 covers the requirements for steel sheets, strips, and coils coated with Zinc, Aluminium and Magnesium alloy for corrosion resistance improvement.
- Specifies Chemical Composition of Coating the standard stipulates the correct proportion of Zinc, Aluminium, and Magnesium in the coating for optimal protection and performance.
- Sets Coating Mass and Thickness Criteriasets requirements for weight and thickness of coating to ensure long service life against rust and environmental damage.
- Mechanical and Quality Parameters Included IS 18513 defines the tensile strength, bendability mechanical properties, and adhesion to guarantee aptitude for forming as well as for structural use.
- Provides test and inspection methods It includes procedures for testing coating quality, corrosion resistance, and the overall performance of the products to determine its conformation to BIS.
Why is BIS Certification Mandatory
BIS certification is compulsory for Zinc-Aluminium-Magnesium (ZAM) coated steel with the aim of ensuring that the product meets the quality, safety, and performance requirements that are specified under IS 18513. This type of BIS certification follows a code of practice for the manufacturing of steel materials, thereby providing guaranteed quality steel materials that are dependable and trustworthy. This is certification in preventing wastages due to environmental factors.
Key Reasons:
- Ensures Product Quality and Standard Compliance :BIS certification ensures that the quality and technical specifications of IS 18513 are met in the ZAM coated steel.
- Protects Against Corrosion and Failure:It ensures the correct composition and thickness of the coating. This, in turn, offers good corrosion protection and extends the service life.
- Mandatory for Legal Sale in India :The manufacturers have to secure BIS certification if they wish to manufacture, sell, or distribute ZAM coated steel.
- Builds Customer Trust and Market Acceptance :The BIS Standard Mark gives customers an assurance that the product is reliable, safe, and approved.
- Required for Government and Industrial Projects: The use of BIS-certified steel is sometimes mandatory for construction, infrastructure, solar, and other industrial applications.
