BIS Certification for Galvanized Steel Sheets (Plain and Corrugated)– IS 277: 2003

Galvanized Steel Sheets ( Plain And Corrugated).

Product Description

Galvanized steel sheets are widely used in construction, roofing, and various industrial applications due to their corrosion-resistant properties. These sheets are coated with zinc to protect the underlying steel from environmental elements. The BIS certification under IS 277:2003 ensures that galvanized steel sheets, both plain and corrugated, meet national standards for quality and durability, offering long-term performance in environments exposed to moisture and corrosive elements.

Introduction

IS 277:2003 defines the requirements for galvanized steel sheets, both plain and corrugated, that are used primarily for roofing and other industrial applications. These sheets are manufactured by coating steel with a layer of zinc to protect against rust and corrosion. The BIS certification under this standard is essential to ensure the products are suitable for use in construction, especially in environments where they are exposed to moisture and atmospheric conditions that promote corrosion. Obtaining the ISI mark assures users of the quality, durability, and corrosion resistance of the product.

Why is BIS Certification Necessary for Galvanized Steel Sheets?

BIS certification for galvanized steel sheets is important because it ensures the sheets meet the quality standards required for various industrial and construction applications. The certification verifies that the sheets are manufactured to withstand corrosion, provide structural stability, and meet required thickness and strength specifications. It also assures customers that the product has been tested for durability, ensuring it performs reliably for a long time, even in harsh environmental conditions.

Overview of Indian Standard IS 277:2003

IS 277:2003 specifies the requirements for galvanized steel sheets, including plain and corrugated types. Key provisions include minimum zinc coating thickness for corrosion resistance, mechanical properties like tensile strength, and consistent dimensions. The sheets must have a uniform surface free from defects such as cracks and blisters, ensuring long-term durability in various environments. Regular testing ensures compliance with quality standards, guaranteeing the sheets' strength, performance, and resistance to corrosion in moisture-exposed conditions.

Process for BIS Certification

The BIS certification process for galvanized steel sheets under IS 277:2003 involves several key steps:

  1. Application Submission: Manufacturers submit an application form, product specifications, and other required documentation.
  2. Document Review: BIS reviews the documentation to confirm compliance with IS 277:2003.
  3. Factory Inspection: BIS inspects the manufacturing facility to ensure that the production processes and quality control measures are in place.
  4. Sample Testing: Samples of galvanized steel sheets are tested for mechanical properties, coating thickness, corrosion resistance, and other required characteristics.
  5. Certification Grant: If the product meets all the requirements, BIS grants certification and allows the manufacturer to display the ISI mark on the sheets.

Documents Required for BIS Certification

Manufacturers applying for BIS certification for galvanized steel sheets under IS 277:2003 must provide the following documents:
