CIRCULAR HOLLOW SECTIONS

Best suited for Structural & Aesthetic Applications
circular hollow section sizes

Manufactured using high quality pure steel HR coils up to a maximum size of 600mm NB, Tata Structura Circular Hollow Sections are light in weight and having high strength. The sections are easy to bend & ideal for welding making it perfect to construct unique & aesthetically appealing structures without compromising strength, beauty & durability. With an assured yield strengths ranging from 210 MPa, 310 MPa, 355 MPa and 420 MPa, these hollow sections or steel tubes can be designed sustain heavy loads with ease. Unlike other secondary steel sections, the chemical composition of steel will not allow any cracks to develop during welding. Thus, making it more suitable to use for a quality steel construction that saves cost as well as time.

The HR coils used to manufacture the steel sections are made in accordance with the highest degree of international quality & the steel tubes are manufactured as per IS 1161. The sections also come with a test certificate which is proof that the steel tubes have undergone and passed all the necessary quality tests.

Circular Hollow Section Weight Table:-

FAQs

It is a metal profile made of steel with a circular cross section. It is predominantly used in structural applications and is defined by 2 factors namely the outer diameter and thickness.
Circular hollow sections are used as structural compression members where the unsupported length is equal in all directions.
They are also used as struts & tie members of a truss. Adding on the shape of circular hollow sections attracts minimal wind force making them ideal for poles, transmission line and communication towers too.
The weight of a circular hollow section can be calculated using the circular hollow section weight calculator.
It requires the outer diameter and thickness of the section. Alternatively, the details can also be accessed from Tata Structura’s product catalogue.
The dimensions of circular Hollow Sections offered range from a minimum bore diameter of 15 mm to a maximum of 600mm with a minimum thickness of 1.6 mm and maximum thickness of 20 mm.
Circular hollow sections come is two types seamless and welded. Tata Structura’s circular hollow sections are all welded and formed through ERW process.
Circular steel hollow sections are made by ERW process. The HR steel strips are cold rolled into a circular profile and the edges along the length are welded using high frequency induction welding process.
The dimension of the circular steel hollow section depends on the width of the HR steel strip.
