Coated Steels | Carbon Steels

Steel is an alloy of iron and other elements, primarily carbon, that is widely used in construction and other applications because of its high tensile strength and low cost.  It is a major component in buildings, infrastructure, tools, ships, automobiles, machines, appliances, and weapons.

Camber

Over 1/2" to 1 1/2" (1/2" in any 8')
Over 1 1/2" to 24" (1/4" in any 8')
  • Camber is to be determined by placing an 8ft. straight edge against the concave edge of the strip.
  • Camber is the greatest deviation of the side edge from a straight line; the measurement being taken on the concave side with a straight edge.
