Circular Hollow

These​ ​tubes​ find​ ​use​ ​in​ ​various​​ structural​ ​ components​ ​in​ engineering​ ​projects​ such​ ​as prefabricated​ ​houses,​ ​containers,​ and​​ light​​ steel​ ​structures. A CHS​ ​ differs​​ from​ ​a ​Round​ ​Pipe.​ ​CHS​ ​are​ ​structural​ ​components​ ​hence​ ​their​ ​external diameter​ is​ ​the​ ​point​ ​of​ ​focus.​ ​Round​​ pipes​ are​​ used​​ for​ ​fluid​ ​ flow​ ​ applications;​ ​hence​ their internal​ ​diameter​ ​is​ ​the​ ​point​ ​of​ ​focus.
