BIS Certification for Hollow Steel Sections For Structural Use IS 4923

In India, BIS Certification for Hollow Steel sections is compulsory. The standards ensure the quality and safety of the products. Standards will inspect the manufacturing infrastructure, quality control practices, and testing capabilities of the company. The process will ensure that raw materials and production methods used in making the structural hollow section meet the criteria set out in IS 4923. It will also ensure compliance by stipulating that hollow sections meet the criteria set out in IS 4923. It will also ensure compliance by stipulating a requirement to maintain a laboratory for in-house testing. 

The standard includes the manufacturing, material, chemical, and testing requirements for structural hollow steel sections (HSS). One of the requirements for manufacturers of HSS is that they are permitted it become certified to market these products in India. This assures the hollow steel sections are safe and will perform as required for structural applications.

 

BIS License for Hollow Steel Sections for Structural Use

Manufacturers seeking BIS-certified hollow steel sections intended for structural applications must satisfy the requirements set out in the relevant Indian Standard, IS 4923. Throughout the construction industry, hollow steel sections (HSS) and other multi-purpose structural components are valued because of their high strength-to-weight ratio, toughness, durability, and cost-effectiveness.

 

HSS are produced in a variety of shapes, including tubular shapes, square, and rectangular. Beyond the durability, structural integrity, and aesthetic advantages of these shapes, HSS also offers numerous benefits, including significant material savings, lower transportation costs, improved fabrication and joining versus solid steel members. HSS are used widely in a variety of applications, including building frames, bridges, towers, and offshore structures.

 

Manufacturers seeking BIS-certified hollow steel sections intended for structural applications must satisfy the requirements set out in the relevant Indian Standard, IS 4923. Throughout the construction industry, hollow steel sections (HSS) and other multi-purpose structural components are valuable because of their exceptional strength-to-weight ratio, high resistance to torsion, and aesthetic appeal.

 

Key Specification of IS 4923

IS 4923 specifies the Indian standard for structural hollow steel sections. It provides for specific sizes, wall thicknesses, material grades, and tolerances as follows: 

Dimensions:

• Circular sections: Outer diameters of 21.3mm-457.2mm
• Wall thickness: 0.5mm-25mm
• Length: 6m-18m; longer lengths available on request.

 

Material Grades

YST 210, YST 240, YST 310, YST 355, FE 330, and FE 410.

 

Mechanical and Chemical Properties

• For YST 310: Minimum Yield Strength of 310 Mpa and Minimum UTS of 450 Mpa450 Mpa 450 Mpa. 
• For YST 355: Maximum Phosphorus content of 0.05% and the maximum Sulphur content of 0.05%. 
• Raw material: Steel should not have more than 0.040% Sulphur and 0.040% Phosphorus. Copper-bearing steel may be used if mutually agreed upon.
