Get BIS Certificate for Zinc, Aluminum, Magnesium Products
Updated on August 02, 2025 03:47:16 PM
The hot-dip zinc-aluminum-magnesium alloy coated steel sheets, plates, and strips can be classified as one of the new breakthroughs of the material of science and engineering since they have the feature of high durability and corrosion protection for many applications. This advanced hot dip coating technique is used to dip the substrates in a molten metallic bath containing zinc, aluminum, and magnesium and produces a stronger anti-corrosive shield than the accepted galvanization techniques. In India, the Bureau of Indian Standards (BIS) has established IS 18513:2023 to control the quality and performance of these coated products to specific controls like safety and reliability.
It is because processing industries require steel materials that can deal with difficult conditions of varying environments that the application of Hot-Dip Zinc-Aluminium-Magnesium Alloy Coated Steel has gained the recognition that it enjoys today. In this blog the following topics will be covered: manufacturing of plates, performance characteristics of plates, methods of testing the performance, and the all-important factor that is BIS certification. In the case of the two above-mentioned aspects, the manufacturers can have an understanding of the various benefits of these advanced materials in construction, automotive parts as well and infrastructure development that in the end can help to improve on safety or durability of the steel structures and hence improving on the safety and sustainability in the construction industry.
BIS Registration Sample
Hot-dip zinc-aluminum-magnesium Alloy Coated Steel Sheets, plates, and strips for building construction since they offer much better protective layers and reasonable useful characteristics. The coating is a method under which, steels are submerged in a molten zinc-aluminum-magnesium bath to form a surface layer that actuates the metallic properties of steels for usage in severe conditions. This means alloy coating has advantages over galvanization such as increased resistance to corrosion, improved adhesion, and mechanical properties.
The Indian Standard IS 18513:2023 prescribes the standard for these coated products to provide quality products that meet certain quality standards. This standard is a major component in a large campaign by the BIS to address issues with the quality of steel products in India especially those used in major construction and infrastructure development projects.
The manufacturing process for Hot-Dip Zinc-Aluminium-Magnesium alloy-coated steel involves several critical steps:
According to the required application, plywood has to possess various performance characteristics. These include:
Testing methods for Hot-Dip Zinc-Aluminium-Magnesium alloy-coated steel are standardized to ensure consistency and reliability:
These should be the first scans that identify any irregularity on the surface of the work.
With methods that do not involve the destruction of the product such as through magnetic induction or eddy current.
Neutral Salt Spray Test (NST): Determines long term corrosion resistance by exposing samples to a saline mist.
Cyclic Corrosion Testing (CCT): Mimics real life environmental conditions for protracted periods of time.
Tensile Strength Tests: For qualifying yield strength as well as the ultimate tensile strength of a metallic product.
Bend Tests: To determine the ductility and flexibility of the coated material.
To conduct testing on the Hot-Dip Zinc – Aluminium – Magnesium Alloy Coated Steel Sheets, Plates, and Strips effectively, laboratories must adhere to specific requirements:
Labeling and markings are fundamental requirements of BIS standards regarding specifications for Hot-Dip Zinc – Aluminium – Magnesium Alloy Coated Steel Sheets, Plates, and Stripss. Each product must include:
The following are the given documents for BIS Certification:
| General Documents | Technical Documents |
|---|---|
| Business License | Plant Layout |
| Trademark License | List of Manufacturing Equipment |
| Application Form | Manufacturing Process Flow Chart |
| Authorization Letter | Product Literature |
| Laboratory Test Reports | List of testing equipment and machinery |
| MSME Certificate | Product’s Technical Specification |
| List of Calibration Certificate |
The BIS certification process for Hot-Dip Zinc – Aluminium – Magnesium Alloy Coated Steel Sheets, Plates and Strips involves several steps:
Applications are filled including relevant documents that outline the production processes of the manufacturers.
A BIS officer pays a visit to the manufacturing company in order to assess the levels of compliance with set regulations.
The samples from the production batches are analyzed at the BIS-accredited laboratories.
As a result of the evaluation of these facilities and products, BIS grants permission to the manufacturers to use the ISI mark on their products.
To sustain the standards practice, normal assertions are carried out.
This is a process that the manufacturers need to understand so that they can get an efficient certification process.
BIS certification is crucial for several reasons:
Conclusion
Hot-dip zinc-aluminum-magnesium alloy Coated Steel Sheets, Plates, and Strips are new-generation materials that are developed for enhancing life and corrosion protection in respective applications. The implementation of IS 18513:2023 focuses on the improvement of product quality by providing tests and certifications by BIS in India. Anyone wanting to obtain BIS certification must go through a flowchart of a series of activities that involve document submission, compliance testing, factory audits, and compliance with labeling standards. Finally, this certification helps to open new markets for steel products and greatly promotes consumer protection and trust in Book steel used in various industries.

It is a protective coat that is deposited on steel sheets by bathing the sheets in molten zinc-aluminum magnesium alloy.
It provides checking on national safety, acting as a guarantee of quality to buyers and monitoring units.
Some other tests include corrosion resistance tests i.e. salt spray tests, peel adhesion testing, and tensile testing among others.

They've been very helpful in our registration with ICEGATE. It was a small thing with a small amount paid which somehow escalated to a very painful procedure. Never did they say "You've only paid so much. It's too much effort for us.".
Very pleased with their service. Prompt, professional and great communication. Definitely recommend. Special mention for Ms. Razia - she handled our case.
Professional Utilities is fully professional in their work, Rates are too low and genuine. Services and satisfaction are high so I highly recommended Professional Utilities.
They are one of the most genuine and reasonable people. I applied for lmpc certificate through them and they charged me a very nominal amount as compared to what other firms asked .
