Hot Rolled Steels
    Hot Rolled Steel is a method by which red-hot billets of steel are squashed between different shaped rollers to produce pre-formed steel products like I-Beams, C-Channels, Angles, etc. It is also available in tubes, pipes, bars, sheets, and thick plates. It's the most prevalent, least expensive steel available. It's the "structural" steel that skyscrapers are made from. It's the "mechanical" steel of square tubes and angles that simple structures are made of. Because it's produced hot and cools after it's done, the forms in which it's available are less fine and less precise than it's sister, Cold Finished Steel. The vast use of Hot Rolled Steels normally is not seen - it's behind the walls and under the floors and in back of the veneered panels. But occasionally it's used in a visible piece. Such is the case in the photos below.
   Hot Rolled Steel's identifying surface finish is the blue-grey oxide scale that covers the naturally-grey color of steel metal. It can be welded, shaped, drilled, formed, forged, and is in every way a versatile and affordable material. You just have to put up with the rough finish and imprecise dimensions.

Below are some images of Hot Rolled Steel work that we've built.
   This staircase stringer is built from Hot Rolled Steel structural elements. The characteristic round corners are evident in the stringer. The balusters and rail cap support on the other hand are made from Cold Finished Steel which has sharp corners and a fine finish.
   This is another staircase made entirely from Hot Rolled Steel elements on which fine wood treads have been placed making a striking contrast.
