A slab or ingot of steel that has been heated above its recrystallization temperature and then rolled to the required thickness is referred to as hot rolled steel plate (up to 6 mm) sheet and strip. The product of this procedure, known as hot rolling, is flat steel sheets or strips with variable widths. When strength and economy are more important than precise dimensional tolerances and a beautiful surface finish, hot rolled steel is the better choice.
Gas cylinders made of liquid gases at low pressures are commonly made using hot rolled steel plate (up to 6 mm) sheet and strip. Gases like propane, butane, and refrigerants are stored and transported using these cylinders.
Many variables, such as industrial and economic situations, safety standards, technical breakthroughs, and the use of liquefied gases, impact the need for hot rolled steel plate (up to 6 mm) sheets and strips to construct low pressure liquefiable gas cylinders.
The integrity of gas storage and transportation systems is ensured by manufacturing these steel items with the utmost safety, standard compliance, and material attributes. Standards for this steel's quality and safety are essential for averting mishaps, safeguarding users, and meeting the operating requirements of several industries.
Under IS standard IS 6240: 2008, all hot rolled steel plate (up to 6 mm) sheet and strip used in the production of low pressure liquefiable gas cylinders is required to be certified by ISI.
Without the ISI Mark, this product cannot be marketed, imported, or exported into the Indian consumer market.
Indian Standards Institute, or ISI was renamed the Bureau of Indian Standards (BIS) in 1987. The official mark that the Bureau of Indian Standards provides for manufacturers of various goods is the ISI Mark. It is used to indicate compliance with Indian standards (IS) set by the Bureau of Indian Standards (BIS) and has been used as a conformity marking for industrial products. Manufacturers received permission from BIS to use the ISI Mark on items that comply with relevant Indian requirements through the product certification program.
Only manufacturers (domestic or foreign) who produce the finished product will be awarded ISI Certification. This will not be given to any product importers, traders, dealers, or distributors.

There are two approaches for Indian manufacturers to become certified with the ISI Mark:
Regular Procedure
With the possible exception of cases deemed "All India first," which might take up to 180 days, the licensing procedure is expected to be finished in 120 days. This timeline starts on the day the application is received, assuming that at different points in time the documentation, unit assessment, and product conformance are all deemed acceptable.
Step 1: Manufacturing Unit Customization in Compliance with Applicable Indian Standards
Step 2: Submission of the Application Form

Simplified Procedure
This is a much faster process than the standard procedure. After a factory inspection is deemed satisfactory and the initial evaluation establishes that the sample complies with the applicable Indian Standard(s), the license application process is expected to be finished in 30 days.
Step 1: Adapting the Manufacturing Unit to Comply with the Relevant Indian Standard
Step 2: Sample Testing
