This standard outlines the specifications for hot-rolled steel strips categorized into three grades: soft, medium, and hard. These strips have a nominal thickness of less than 3 mm and a width of less than 75 mm, often referred to as baling hoop.

The steel strips should be manufactured using steel produced through open hearth, electric, duplex, basic oxygen processes, or a combination of these methods. It's essential for the materials to adhere to the chemical composition requirements outlined in the standard and be devoid of any detrimental defects. Unless stated otherwise, the hot rolled steel strips should be provided in dimensions as mutually agreed upon between the purchaser and the manufacturer.

TESTS

The subsequent test must be conducted for Hot rolled steel strip.

• Chemical composition

• Tensile test

• Bend test

PACKING AND MARKING:

Packing and marking procedures should adhere to IS 1029:1970 standards. Each length of the strip must be clearly marked with the size and grade of the material. Additionally, the product may feature a standard mark (ISI Mark).

Manufacturers are required to acquire a BIS license from the Bureau of Indian Standards in order to utilize the standard mark (ISI Mark). This license is granted following a thorough evaluation of manufacturing infrastructure, production processes, and quality control and testing capabilities during an inspection at the manufacturing premises by the Bureau.
