Architecturally Exposed Hollow Structural Sections | Steel ...It should be noted that not all round HSS are produced with one straight seam weld. Particularly in larger round sections (greater than 16 inches in diameter), members may be supplied to a job with a spiral weld, where a steel coil is unwound and then welded while it is being turned into the shape of a pipe.
