What is structural steel? Variety of heavy steel shapes (such as the H-beams, I-beams, and T-beams) used as load bearing members of a structural frame. Collectively called structurals. What is the difference between iron and steel? Iron is an element that when combined with carbon and other elements makes steel. Who invented steel? Most credit Henry Bessemer with the invention of steel in 1856. He founded the Bessemer Steel Company in Sheffield, England. Today, steel is still produced using technology based on the Bessemer Process of blowing air through molten pig iron to oxidize the material and separate impurities. What is meant by a “net” ton? Net means the measurements of tons as 2,000 pounds. For every net ton, that equals 2,000 pounds. Where can I find detailed information regarding worldwide pig iron production including: production plant name, production process type, capacity of the plant, type of solid residues/chemical composition of it, reuse of the residues/costs or benefits out of it, etc.?

Is all metal pipe made from plate, then rolled? How is the seam closed? Some pipe is pierced from a billet or bloom. Other pipe is cast. However, most pipe is rolled from steel plate, that is rolled into a pipe and welded closed. There are, of course, various forms of nonsteel pipe. Where can I find information about comparable steels, based on chemical composition and/or mechanical properties? You can find this in the 2nd Edition of Handbook of Comparative World Steel Standards available at ASTM at www.astm.org or order the DS67 B (handbook) at 610-832-9585 or fax 610-834-3636 email service@astm.org At what strength (PSI) is steel considered structural steel? Structural steel is a term used in the ASTM standards. You may obtain the definition by checking with American Society for Testing Materials (ASTM), 100 Barr Harbor Drive, West Conshohocken, PA 19428, Phone #610-832-9500, Fax #610-932-9555, Website; http://www.astm.org.
