SECURING BIS CERTIFICATION OF HOT-DIP ZINC-ALUMINIUM-MAGNESIUM ALLOY COATED STEEL SHEETS

INTRODUCTION

In the search for materials with exceptional corrosion resistance and durability, hot-dip zinc-aluminium-magnesium alloy coated steel stands out. This innovative product is widely used in construction, automotive, and industrial sectors, offering a perfect balance of strength and environmental resistance. To ensure these products meet rigorous quality standards, the Bureau of Indian Standards (BIS) has established IS 18513. This article explores IS 18513, the BIS certification process, and how Absolute Veritas helps manufacturers achieve compliance.

INDIAN STANDARD IS 18513

IS 18513 specifies the requirements for hot-dip zinc-aluminium-magnesium alloy coated steel sheets, plates, and strips, ensuring they can endure harsh environments and maintain structural integrity.

Key aspects of IS 18513

• Chemical Composition: The standard details the precise balance of zinc, aluminium, and magnesium in the alloy coating, essential for achieving optimal corrosion resistance and mechanical properties.

• Coating Thickness and Mass: IS 18513 mandates minimum coating thickness and mass to ensure uniform protection across the product's surface, which is crucial for consistent performance.

• Mechanical Properties: The standard defines required mechanical properties such as tensile strength and elongation to ensure the steel can handle mechanical stress while preserving the coating’s integrity.

• Surface Appearance and Finish: IS 18513 requires that the coating's surface be free from defects that could affect its performance or appearance.

DRAFT QUALITY CONTROL ORDER

The Technical Division of the Ministry of Steel, Government of India, has proposed a draft order mandating that all Hot-Dip Zinc-Aluminium-Magnesium Alloy Coated Steel Sheets, Plates, and Strips used in India—whether produced domestically or imported—must carry the Standard Mark from the Bureau of Indian Standards (BIS) under a valid BIS license.

BIS CERTIFICATION FOR IS 18507:2024

BIS offers a certification scheme to ensure steel and steel products meet Indian standards. This process involves rigorous evaluation and testing to confirm compliance with specific standards. Once products pass the assessment, BIS certification is granted, affirming their quality and regulatory adherence. This certification is a mark of reliability and trust, enhancing market acceptance and competitiveness.

The certification process under IS 18513 is detailed and comprehensive, covering key aspects such as chemical composition, particle size, and other critical parameters. For manufacturers, obtaining BIS certification is a sign of their commitment to quality and excellence. However, navigating this certification process requires a thorough understanding of the standards and careful preparation.
