Hector Guerra from Larson Steel came by this morning to show Bryan the HSS 5×5 by 1/2 inch tube steel.
Designing the Bridges
Hector and Pete Larson wanted to ensure that we knew exactly what the tube steel would look like and set our expectations accordingly.
Hector had a couple feet of the tube steel with him and showed Bryan how the corners have ~ 1 inch radius curve. Hector explained that the thicker the wall of the tube steel, the larger the radius. This is the same with, say, HSS 2×8 by 3/16 tube steel. The corners are rounded, not square.
We thought the steel looked great.
