Structural, Carbon &
HSLA Steel Plate
ASTM A656

A high-strength, low-alloy, hot-rolled structural steel plate utilized in structural applications where lighter weight and improved formability is critical. Applications include: truck frames, crane booms, and rail car components. Made to Grades 50, 60, 70 and 80— the grade designating the yield strength. Chapel Steel stocks in Grade 80 up to 3/4’ , Grade 70 over 3/4” to 1” and Grade 60 over 1” to 1-1/2”.
