Description / Abstract:
This specification covers cold-formed welded and seamless
high-strength, low-alloy round, square,
rectangular, or special shaped structural tubing for welded, riveted,
or bolted construction of
bridges and buildings and for general structural purposes where high
strength and enhanced
atmospheric corrosion resistance are required (Note 1). The
atmospheric corrosion resistance of
this steel in most environments is substantially better than carbon
steel with or without copper
addition (Note 2). When properly exposed to the atmosphere, this steel
can be used bare (unpainted)
for many applications. When this steel is used in welded construction,
the welding procedure shall
be suitable for the steel and the intended service.
