Triad Metals Jumbo HSS Logo

The Largest Size Metal Tubes Made

Triad Metals is a top provider of steel hollow structural sections (HSS) in sizes ranging from 10″ to 22″ square, with wall thicknesses up to 0.875″. Jumbo HSS are readily available for ASTM A500, ASTM A1085 and CSA G40.21.

Jumbo HSS are typically used in vertical columns and diagonal bracing applications. They offer enhanced performance for large, long-span trusses and are a superior, cost-effective alternative to open sections and built-up, welded box sections used in structures with a high load demand.
