Dive summary:

• A new ASTM standard A1085 for hollow structural steel round and rectangular materials is a good thing for bridge and building designers, steel fabricators say.
• The standard eliminates the need to reduce nominal wall thickness for calculations and sets a single minimum yield strength, which will make hollow steel a more attractive design option.
• The specification for cold-formed welded carbon steel hollow structural sections also now has a maximum yield stress.

"A1085 makes designing with HSS easier and more efficient for both building and bridge construction," said John Simon, vice president of sales with AISC-member EXLTUBE. ...
