- IS 277:2018 specifies the standards that the galvanized steel strips and sheets should follow in terms of their chemical composition, coating thickness, mechanical strength, and dimensional accuracy.
- BIS certification is an indication of the product’s quality that ensures its resistance to corrosion, its longevity, and its good performance even in harsh conditions.
- The ISI mark is mandatory if one intends to manufacture and galvanize steel strips and sheets in India. Thus, it is a way of assuring product safety for consumers.
- Getting a BIS certificate may be compared to a relay race where every stage is crucial for the successful ending: documentation, product testing, factory inspection, approval, and, finally, issuing the licence.
- Standard-compliant products enhance brand trust, the likelihood of industrial application without product failure, and become a source of structural reliance over time.
Introduction
Galvanized steel strips and sheets play a vital role in situations that demand high resistance to corrosion and durability for a long period of time. The steel is coated with zinc as a protective layer in order to prevent rust and any kind of deterioration that may result from the passage of time. In case these materials are exposed to severe conditions and are still used in situations, conformity with IS 277:2018 guarantees that they satisfy the necessary mechanical as well as dimensional Bureau of Indian Standards requirements.
What are Galvanized Steel Strips and Sheets IS 277:2018?
Galvanized Steel Strips and Sheets IS 277:2018 defines an Indian Standard that outlines the zinc-coated steel strips and sheets requirements. It specifies the standard:
- Chemical composition – Offering strength and flexibility.
- Physical properties – Tensile strength, elongation and bend tests.
- Coating thickness – Giving corrosion protection for a long time.
- Dimensional accuracy – Standardized width, thickness and tolerances.
- Surface finish – A uniform and clean surface without any cracks, pits or other defects.
- Testing and inspection methods – Helping the quality to be the same throughout the whole batch.
By implementing IS 277:2018, the steel strips and sheets are able to retain their strength, surface finish, and protective layer, at least, up to their service life.
ISI Mark Certification for Galvanized Steel Strips and Sheets
Galvanized steel strips and sheets under the ISI Mark Certification Scheme need to conform to the IS 277:2018 standard in order to be marketed in India. Certification is a guarantee of:
- Standard mechanical properties.
- Corrosion resistance and service life.
- Dimensional accuracy for the exact applications.
- Quality control at the production batch level even from small-scale industries.
Manufacturers are allowed to affix the ISI mark only after they get a valid BIS licence.
Why keeps it mandatory for Galvanized Steel Strips and Sheets to be BIS certified?
A defective galvanized steel might become a cause of the following problems:
- Corrosion and rusting may happen within a very short period of time.
- A metal framework may crash because of using galvanized steel strips and sheets for building and industrial purposes.
- Maintenance costs will be elevated and replacement will be carried out more frequently.
- The lifespan of the second-hand market and parts will become shorter.
The Bureau of Indian Standards (BIS) certification is a comfort to:
- Compliance with IS 277:2018.
- Ability to handle mechanical and environmental stress.
- Reputation with customers and good market standing.
- Free from corrosion and wear for a long time.
Importance and Benefits of BIS Certification
| Importance | Benefits |
| Compliance with IS 277:2018 | Allows metal to resist rust and keeps it durable |
| Standardized production | Ensures the product has the same quality and strength as specified |
| Mechanical reliability | Reduces risk of failure in construction and industrial applications |
| Regulatory compliance | Avoids legal issues and market rejection |
| Brand credibility | Enhances customer trust and industry reputation |
Step-by-Step BIS Certification Process
Step 1: Documentation
– Prepare the details of the company, its production facilities, and the product with reference to BIS standards.
Step 2: Product Testing
– Samples of galvanized steel strips and sheets are analyzed in laboratories recognized by BIS to confirm chemical composition, coating thickness, and mechanical properties.
Step 3: Application Submission
Upload the test reports along with other supporting documents on the BIS portal for the department to take a look at them.
Step 4: Scrutiny & Inspection
i The factory inspection is part of the standard manufacturing practices and quality control measures that are checked by BIS through a visit to the production site.
Step 5: Grant of Licence
– After a triumphant inspection, BIS is granting the licence enabling the producers to put the ISI mark on the certified galvanized steel strips and sheets.
Documents Required for BIS Certification
- Company registration certificates.
- Details of the manufacturing unit.
- Technical details of galvanized steel strips and sheets.
- Test reports from a BIS-recognized laboratory.
- Brand authorization (if applicable).
Timeline, Validity & Renewal
- Certification Timeline: 20–30 working days.
- Licence Validity: 1–2 years.
- Renewal: Submission of updated documents and confirmation of continued compliance before expiry.
Conclusion
BIS certification for Galvanized Steel Strips and Sheets IS 277:2018 is a sign that the product is made of high quality, safe and performs well. The certified products guarantee excellent corrosion resistance, stable mechanical properties, and uniform dimensional accuracy. In the sectors where the use of the product for a long time is the main issue, employing galvanized steels certified by BIS not only provides safety and efficiency but also enhances the company’s reputation.
Complying with the standard IS 277:2018 for galvanized steel is more than just a legal obligation – it is a wise decision that will bring quality, reliability, and customer loyalty to your business..
