Steel is evaluated in different grades, specifications, shapes and finishes. There are different grades of steel, and each has its own unique properties. It ensures these products meet the Indian standard for mechanical properties testing and chemical composition.

 

These hot-rolled alloy steel bars are industrial metal components that undergo a shaping process at a temperature above 1000°C, which offers high strength and durability for heavy-duty applications. Good quality materials are crucial in the steel industry to ensure the products are safe and do not violate any regulations set by the Indian Government.

 

Why does BIS/ISI Certification for IS 19559 Steel bars matter?

IS 19559, the Standard, ensures that hot-rolled Alloy Steel Bars meet compliance requirements, verifying that the steel products are safe and building trust and reliability in the steel industry. The quality and compliance are not just important-they are essential.  Go through the key points of reasons why Certification matters for Steel manufacturers:

  • Legal and mandatory Compliance requirement
  • Provides access to the government tenders
  • Provide prevention from penalties and material seizures
  • The certified steel bars provide high-quality assurance
  • Builds a brand's name by increasing product credibility

 

Is BIS Certification Mandatory for Alloy Steel Bars Grades in India?  

Yes, BIS/ ISI mark certification for IS 19559 steel bars is mandatory. A Quality Control Order (QCO) issued by the Ministry of Steel, hot-rolled steel products, including Alloy Steel Bars, states that both foreign and domestic manufacturers must comply with the Indian standards for steel products before being manufactured, imported or sold in India.
