Description
Hi-Tech Pipes YST 355 Circular Hollow Section Hi-Tech YST 355 80 NB MS CHS (88.9 x 1.2 mm) - 6 mtr Length is manufactured by the ERW process to IS 1161:2014 with a 88.9 mm outer diameter, 80 NB designation, and 1.2 mm wall thickness in standard 6 m lengths. Delivering minimum yield of 355 MPa and tensile strength of 490 MPa, this CHS tube is engineered for medium-duty structural columns, industrial frames, and mechanical/structural tube applications where equal radial load resistance and aesthetic finish are valued. The smooth circular exterior of this tube offers minimised wind and fluid resistance, while the closed hollow section provides excellent torsional and bending stiffness in structural applications.
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
