EN 10210 S355J2 Hot Finish Rectangular Hollow Section Welded Tube, EN 10210 S355J2+N Hot Finish SHS EN 10210 S355J2+N CF SHS, EN 10210 S355J2 Cold Formed RHS, EN 10210 S355J2+N CS Cold Formed Square Hollow Section.

There are several benefits of the square hollow section constructed of EN 10210 S355J2, including its durability and affordability. Furthermore, it has advantages like a corrosion-resistant finish, exact dimensional measurements, application-specific design, and more. Customers from all around the world mostly utilize this for structural and mechanical tasks. For the benefit of the valued clients, this hollow area contains material of an exceptional quality that has not been treated. The finest steel and cutting-edge technologies are used in manufacturing to create this readily available square hollow section. Its durable structure has earned it a lot of popularity. It has a dimension range of 21.3 to 1219 mm. 

The most popular austenitic grade carbon steel hollow section is the rectangular EN 10210 S355J2 hollow section. The pipes are used in high-stress situations and are manufactured using high-frequency induction welding, or HFW. The grade has nominal bore sizes up to 300mm and an outer diameter range of 21.3mm to 457.2mm. These pipes range from 6000 mm to 18000 mm and have wall thicknesses between 1.8mm and 14.27mm. In terms of manufacture, the pipes might be seamless, welded, or ERW. The substance comprises carbon, silicon, manganese, phosphorus, and sulfur. With a minimum yield strength of 315 MPa, a minimum tensile strength of 490 MPa, and a 22% elongation rate, the chemical construction gives these hollow sections their strength. 

The low carbon grade is S355. The chemical elements that make up these circular hollow sections are carbon, silicon, manganese, phosphorus, and sulfur. These round pieces can withstand extremely high temperatures and have exceptional corrosion resistance in their construction. The hollow parts may have excellent dimensional correctness and better polish. These sections are employed in building important structures since they are both affordable and sturdy. Additionally, the material is constructed with superior mechanical qualities. They have a minimum yield strength of 355 Mpa and a tensile strength ranging from 510 Mpa to 680 Mpa. These materials have good strength and outstanding stress resistance but are not as robust as full-fledged carbon pipes.
