Description
The Hi-Tech Pipes YST 355 Circular Hollow Section Hi-Tech YST 355 15 NB MS CHS (21.3 x 2 mm) - 6 mtr Length is ERW-manufactured to IS 1161:2014 specifications, presenting a 21.3 mm outer diameter at 15 NB with 2 mm wall thickness in standard 6 m lengths. With guaranteed mechanical properties of 355 MPa yield and 490 MPa tensile strength, this CHS tube serves as a reliable structural component for medium-duty structural columns, industrial frames, and mechanical/structural tube applications. The uniform circular cross-section distributes compressive, torsional, and bending loads equally in all radial directions, making it the preferred section for columns, poles, and multi-directional structural frames.
Key Features:- Grade YST 355 IS 1161:2014 certified CHS with guaranteed mechanical properties
- ERW process producing a continuous, sound weld seam along the full tube length
- Yield 355 MPa and tensile 490 MPa for design-critical structural and mechanical applications
- Circular hollow geometry offering maximum torsional stiffness for given wall thickness
- Equal section modulus in all planes enabling efficient multi-directional structural design
- Mill surface suitable for direct fabrication, painting, or hot-dip galvanizing treatment
- Comprehensive range of nominal bore sizes from 15 NB to 80 NB and beyond
- Standard 6 m lengths compatible with standard transport and site storage infrastructure
- Smooth circular finish preferred for architectural and exposed structural steel applications
- Dimensional accuracy per IS 1161 tolerances ensuring interchangeable and precise fit-up
- Load-bearing circular columns in light to medium industrial building structures
- Primary and secondary circular framing posts in steel-framed building construction
- Pedestrian bridge circular handrail post and balustrade column members
- Structural circular tube frames for covered walkways and canopy support systems
- Circular bollard and security barrier post members in commercial environments
- Staircase primary circular post members and landing balustrade uprights
- Medium-duty equipment skid circular frame legs in oil, gas, and process industries
- Structural circular post members for sign gantries and overhead display supports
