- BIS Certification according to IS 16732:2019 is a way to assure that the galvanized structural steel coating of the product is of good quality and is consistent.
- The standard specifies the thickness of the coating, its uniformity, the sticking test, and the control of the process.
- After that, manufacturers undergo sample testing, factory inspection and documentation review to get the ISI mark.
- It is necessary to obtain this certification to be able to supply galvanized steel for large scale infrastructure and government projects.
- Proper process discipline, traceability, and QC records are essential for passing BIS surveillance audits.
Introduction
A few months ago, a fabricator supplying galvanized channels to a metro rail contractor called us in a panic. His consignments were being held up because the project consultant insisted on proof of BIS Certification under IS 16732:2019. His coating thickness was consistent, and the plant had been running for more than a decade, yet the absence of formal certification stopped a crore-level order from moving forward. Situations like this have become increasingly common. Buyers no longer view galvanizing as a simple post-processing activity; they expect documented compliance, traceability, and uniformity that only a BIS-certified process can guarantee. That shift is exactly why IS 16732:2019 has become central to India’s structural steel market. Bureau of Indian Standards
What is IS 16732:2019?
The standard lays out the production and testing methods for galvanized steel to ensure that the steel stays durable against corrosion, performs well mechanically and the coating is of consistent thickness. It is used by manufacturers as a standard of quality when they supply products for the infrastructure, industrial and government projects.
Key Points
- Sets minimum coating thickness and coating mass levels for structural steel parts.
- Specifies mandatory tests, including adherence, uniformity, and zinc coating evaluation.
- Covers quality of base steel, surface preparation and galvanizing bath chemistry.
- Includes strict sampling and inspection rules for BIS certification. ISI MARK
- Requires proper product marking and traceability to maintain compliance.
Why is BIS Certification Mandatory
It is necessary for galvanized structural steel to have a BIS Certification since the Government has decided that IS 16732:2019 will be under compulsory quality control. It is a measure that assures safety-tested and traceable products that are compliant with the standard are the only ones that are allowed to enter the Indian infrastructure supply chain. In the absence of certification, manufacturers are not allowed to put a mark or sell galvanized structural steel as per IS specifications in a legal manner, and their materials are turned down in the majority of public and private tenders.
Key Points
- It is the main point that the quality of the standard thickness of the zinc coating and the level of corrosion resistance, which are very important for structures that have to be used for a long time, are ensured.
- Helps to keep the public safe, who use bridges, metros, towers, solar plants, and industrial structures.
- Creates accountability through factory audits, market sampling and traceability.
- Prevents low-grade galvanizing practices that lead to premature failures.
- Aligns manufacturers with national quality control orders (QCOs) issued by the Ministry of Steel and the Bureau of Indian Standards.

Frequently Ask Questions
What is IS 16732:2019 for galvanized structural steel?
It is an Indian Standard that lays down the requirements for areas such as coating thickness, uniformity, and testing of a galvanized structural steel along with handling the process controls of infrastructure projects.
Is BIS Certification under IS 16732:2019 mandatory?
Yes. The government has been quite clear in this regard as it has put this standard under compulsory quality control meaning that a BIS certification has become a must for a mfg. or sale of structural galvanized steel.
Who needs BIS Certification for galvanized structural steel?
The producers of the beams, channels, angles, plates, or fabricated steel parts who aim to galvanize for areas such as prospective large infrastructure, industrial and government projects need It.
How long does the BIS certification process take?
The time period is about 20–30 days, though it relies on the off-site and on-site inspection, the test schedule, and the documents.
What tests are required under IS 16732:2019?
The key tests consist of thickness of the coating, the weight of the coating, the uniformity (Preece test), the adhesion test, and the quality of the base steel.
Can a manufacturer sell galvanized steel without BIS Certification?
Absolutely not. It is illegal to sell or mark galvanized industrial structural steel without an ISI licence and it results in a tender being rejected as well as legal penalties.
What documents are required for applying?
The applicant must have business registration with a factory layout, a machine list, process flow, product specification, internal QC records, and test reports from a lab that is recognised by BIS.
Does BIS conduct factory inspections?
Yes, they do. BIS officials check in-process controls, bath chemistry, QA systems, calibration records and traceability before issuing the licence.
How long is the BIS licence valid?
A BIS license usually remains valid for two years and after that, it needs to be renewed with updated files and compliance records.
Can Diligence Certifications assist in the BIS process?
Indeed. Diligence Certifications helps manufacturers with paperwork, testing coordination, audit readiness, and complete end-to-end BIS compliance management.
