The meaning of the term &#8220;HSS&#8221; in architecture refers to hollow profiles (round, square, rectangular) specially designed for structural applications, which are different from pressure or mechanical pipes.<\/p>\n\n<p class=\"wp-block-paragraph\">As a leading steel pipe manufacturer and global steel pipes supplier, Allland\u00a0Pipes specializes in producing high-quality welded steel pipe and carbon steel pipe in line with international standards to meet different project needs on all continents.
