Triad Metals Jumbo HSS Logo

The Largest Size Metal Tubes Made

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.
