Is 1161 rectangular hollow sections square tube, Cold Formed IS 1161 YST 240 RHS Pipe, IS 1161 YST 240 Cold Formed Carbon Steel Rectangular Hollow Section, IS-1161 YST 240 MS Cold Formed Rectangular Tube.

Hot and cold-formed square hollow steel sections are covered by the IS 1161 material standard for various applications. Whether it is hot or cold produced, the thickness and OD of the hollow portion determine its classification as either HF or CF. The product's quality has improved as a result of a routine examination. The maker submits various tests to determine the quality of the pipes, including a hardness test, a positive material identification test, macro- and micro-tests, a flattening test, a flaring test, a chemical analysis, and a mechanical test. To ensure excellent manufacturing quality, the manufacturers also make these pipes following national and international product standards. Its standard specifications include ASTM, ASME, DIN, EN, JIS, and others. This hollow portion passes a number of tests, including independent third-party inspection, x-ray, ultrasonic, flaring, chemical, and mechanical testing, among others.

The IS 1161 YST 240 Rectangular Hollow Section pipe manufactured in the hot finish process can also be used for structural usage. The oil refineries, pharmaceutical, chemical, and automotive industries have all used this commodity, with a minimum order quantity of 1 kilogram. These products are customized in the factories where they are made with thickness and sizes as required. The factories have created premium steel products with attributes like moisture and corrosion resistance. These hollow section pipes are available in various forms, sizes, diameters, and thicknesses to fit into different applications. Before shipping, these pipes are put through several physical testing. The thickness varies from 0.5 to 25mm, and the dimension ranges from 10mm x 10mm to 600mm x 600mm. The pipe is randomly cut to lengths between 6 and 12 meters and is then tailored to meet individual client needs. The product has a black and gray hue and is certified to the EN 10204-3.1 standard.
