Introduction<\/h2>\n
Galvanized steel sheets are steel sheets coated with zinc to improve corrosion resistance and provide a durable surface for applications such as roofing, panelling, siding and other general engineering uses. Plain galvanized sheets are also supplied in coils or strips, while corrugated galvanized sheets are formed into a regular corrugated profile for applications where additional rigidity and suitable surface geometry are required.<\/p>\n
For BIS certification purposes, it is important to note that the standard referenced in older material is IS 277:2003<\/strong>, while the current BIS framework identifies IS 277:2018 \u2013 Galvanized Steel Strips and Sheets (Plain & Corrugated) \u2013 Specification (Seventh Revision)<\/strong> as the applicable standard. The BIS Product Manual currently available for certification is based on IS 277:2018<\/strong>, and the current BIS compulsory-certification listing also identifies IS 277:2003 in its historical listing while current testing and certification information is aligned to IS 277:2018.<\/p>\n
The current Steel and Steel Products (Quality Control) Order, 2024 specifically lists IS 277:2018 \u2013 Galvanized Steel Sheets (Plain and Corrugated) \u2013 Specification<\/strong> and provides immediate effect<\/strong> as the implementation date.<\/p>\n
Therefore, manufacturers planning BIS certification today should verify their product against the latest applicable IS 277 edition and amendments<\/strong>, rather than relying only on IS 277:2003.<\/p>\n
Qualitance India<\/strong> provides end-to-end BIS Certification Consultancy for Galvanized Steel Sheets and Strips, including Plain and Corrugated Sheets, covering product scope assessment, documentation, testing coordination, BIS application support and factory inspection preparation.<\/p>\n

What is IS 277?<\/h1>\n
The original IS 277:2003<\/strong> was titled \u201cGalvanized Steel Sheets (Plain and Corrugated) \u2013 Specification.\u201d<\/strong> The standard covered plain galvanized steel sheets and strips\/coils as well as corrugated galvanized sheets.<\/p>\n
The current standard is IS 277:2018 \u2013 Galvanized Steel Strips and Sheets (Plain & Corrugated) \u2013 Specification (Seventh Revision)<\/strong>. The current BIS Product Manual confirms that certification is operated under Scheme-I of the BIS Conformity Assessment Regulations, 2018<\/strong>.<\/p>\n
The current standard addresses important requirements such as:<\/p>\n
\n

Corrugated sheets have a regular formed profile that provides additional stiffness and is widely used in roofing and similar applications.<\/p>\n
For corrugated products, important characteristics include:<\/p>\n
\n
Number of corrugations<\/li>\n
Corrugation depth<\/li>\n
Corrugation pitch<\/li>\n
Overall width<\/li>\n
Thickness<\/li>\n
Length<\/li>\n<\/ul>\n
The current BIS LIMS testing information specifically identifies testing for corrugation depth, pitch, number of corrugations and overall width before and after corrugation.<\/p>\n
Scope of IS 277:2018<\/h1>\n
The current BIS Product Manual identifies several important parameters for the licence scope.<\/p>\n
These include:<\/p>\n
Grade<\/h3>\n
The applicable grade of the galvanized steel sheet or strip.<\/p>\n
Designation<\/h3>\n
The Product Manual identifies designations such as GP<\/strong> for general-purpose products.<\/p>\n

The current BIS Product Manual identifies raw material including, but not limited to:<\/p>\n
\n
IS 513 Part 1 and Part 2<\/strong> for cold-reduced carbon steel sheet and strip<\/li>\n
IS 1079<\/strong> for hot-rolled steel sheet and strip<\/li>\n<\/ul>\n
It also specifies that zinc ingots used for galvanizing shall conform to applicable grades specified in:<\/p>\n
\n
IS 209<\/strong><\/li>\n
IS 13229<\/strong><\/li>\n<\/ul>\n
Manufacturers should maintain traceability of the incoming steel and zinc raw materials.<\/p>\n
Is BIS Certification Mandatory for Galvanized Steel Sheets?<\/h1>\n
Yes. Galvanized steel sheets and strips covered by IS 277 are subject to compulsory BIS certification requirements.<\/strong><\/p>\n
The current Steel and Steel Products (Quality Control) Order, 2024 specifically lists:<\/p>\n
IS 277:2018 \u2013 Galvanized Steel Sheets (Plain and Corrugated) \u2013 Specification<\/strong><\/p>\n
and states that the implementation is with immediate effect<\/strong>.<\/p>\n
BIS’s technical summary also states that the Ministry of Steel’s QCO requires galvanized steel sheets and strips covered by IS 277:2018 to meet the standard and bear the BIS Standard Mark.<\/p>\n
The BIS Scheme-I page also includes IS 277 in the compulsory-certification framework.<\/p>\n
Important: IS 277:2003 vs IS 277:2018<\/h1>\n
This is important for manufacturers and website visitors searching for IS 277:2003<\/strong>.<\/p>\n
The older standard IS 277:2003<\/strong> covered galvanized steel sheets, plain and corrugated.<\/p>\n
BIS subsequently revised the standard to IS 277:2018<\/strong>, titled Galvanized Steel Strips and Sheets (Plain & Corrugated) \u2013 Specification<\/strong>. The current BIS Product Manual is based on IS 277:2018, and the current laboratory database lists testing under IS 277:2018.<\/p>\n
Therefore, a manufacturer looking for BIS Certification for IS 277:2003<\/strong> should first confirm whether the intended certification scope should now be processed under the current IS 277:2018<\/strong> requirements.<\/p>\n
This distinction is especially important for avoiding incorrect applications, outdated testing and unnecessary certification delays.<\/p>\n
Steel and Steel Products Quality Control Order<\/h1>\n
The Steel and Steel Products (Quality Control) Order, 2024<\/strong> lists IS 277:2018 among the covered steel standards.<\/p>\n
For IS 277:2018, the QCO identifies:<\/p>\n
