- Mandatory BIS certification under IS 277:2003 for galvanized steel sheets.
- Ensures corrosion resistance, durability, and safety.
- Required for legal sale and government tenders.
- Confirms coating, strength, and dimensional quality.
- Builds market trust and reduces project risks.
Introduction
One roofing project in Maharashtra suffered early degradation because sheets, made of galvanized steel, did not carry BIS certified compliance to IS 277:2003. Corrosion occurred early due to the inconsistent zinc coating, resulting in an expensive replacement; it happened prematurely, not due to a rain soaked event. The BIS Certification of Galvanized Steel Sheets (Plain and Corrugated) designated to IS 277:2003 is a means to ensure coating uniformity, assessed strength, and durable serviceability. Compliance to this BIS standard, certified by Bureau of Indian Standards, is a statutory requirement for all manufacturers and suppliers of galvanizing steel products in India. Using BIS certified sheets, ensures you (the builder and contractor) safety, conformity and dependable performance on any project.
What is IS 277:2003?
IS 277:2003 is a document under the Indian standard detailing minimum quality and performance expectations for hot dipped galvanized steel sheet products ordered in plain and corrugated formats. It is the product’s indication that its zinc coating, mechanical strengths, and corrosion protection of the product are compliant to the national standard of suitability for roofing, cladding or structural application. ISI MARK
Key Points:
- Covers plain and corrugated galvanized steel sheets produced by hot-dip zinc coating.
- Specifies coating mass, adhesion, and surface finish for durability.
- Defines chemical composition and mechanical properties of the base steel.
- Ensures corrosion protection and longer service life in harsh environments.
- Mandatory for manufacturers under BIS certification to sell in India.
Why is BIS Certification Mandatory
Bureau of Indian Standard (BIS) Certification of galvanized steel sheets in accordance with IS 277:2003, provides assurance that only acceptable, safe, and good quality products are manufactured and sold in India. It should provide some assurance that users, contractors, and public infrastructure are safe from failures due to poor-quality products.
Key Points:
- Liability: It is a legal requirement in the Steel and Steel Products (Quality Control) Order inadvertently issued by MO Steel.
- Quality Assurance: It provides complete confidence that the sheets conform to quality, coatings, strength, and corrosion specifications.
- Public Safety: It provides safety against structural failure of roofs, bridges, and industrial buildings due to substandard steel.
- Market Legality: Only manufacturers licensed with BIS can legally manufacture, supply, and sell galvanized sheets in India.
- Confidence of the buyer: The ISI Mark is a benchmark mark of trust for contractors and clients, assuring them that the material they are receiving has been tested and certified.
Importance & Benefits of BIS Certification
| Importance | Benefits |
| Verifies compliance of galvanized iron sheets with quality and safety requirements of IS 277:2003 | Guarantees uniform zinc coatings, fade resistance and durability |

| Provides reliability of material used for roofing, cladding and structural applications | Reduces maintenance or other costs and chance of premature product failure |
| Introduces accountability, transparency and traceability into the steel manufacturing process | Establishes brand reputation and customer confidence |
| Provides domestic status of product to international standards | Creates opportunities to compete with domestic and export products in the market. |
Step-by-Step Process of BIS Certification
Step1:Documentation
- Collect documents from the factory, including layout, process flow chart, and quality manual.
- Keep calibration certificates and raw material test reports.
- Document Internal quality control procedures and personnel details.
- Verify that all documents meet requirements outlined in the BIS Product Manual.
Step2:Product Testing
- Provide samples of product to BIS accredited or NABL accredited labs.
- Conduct all mandatory tests, including zinc coating mass, adhesion and mechanical strength.
- Confirm all required tests meet specifications set out in IS 277:2003 before submission.
- Retain the approved test report for audits and future renewals.
Step3:Application Submission
- File the online application on the BIS Manakonline portal with all attachments.
- Upload test reports, product details, and manufacturing information accurately.
- Pay the prescribed application and license fees online.
- Track your application status through the BIS dashboard for timely updates.
Step4:Scrutiny and Inspection
- BIS officials review submitted documents for accuracy and completeness.
- A factory inspection is conducted to check production facilities and testing setup.
- Inspectors verify product traceability, process control, and equipment calibration.
- Rectify any non-conformities identified before the final license recommendation.
Step5:Grant of License
- BIS issues the ISI license once product and process compliance are confirmed.
- The manufacturer receives a unique license number and authorization to use the Standard Mark.
- Continuous in-house testing and documentation are required for surveillance.
- License remains valid for two years and can be renewed upon compliance review.
