The output from a strip mill is coiled and, subsequently, used as the feed for a cold rolling mill or used directly by fabricators. Billets, for re-rolling, are subsequently rolled in either a merchant, bar or rod mill. Merchant or bar mills produce a variety of shaped products such as angles, channels, beams, rounds (long or coiled) and hexagons.
Within the trades rebar is known by a shorthand utilizing the bar diameter as descriptor, such as "four-bar" for bar that is four-eighths (or one-half) of an inch. The cross-sectional area of a bar, as given by πr ², works out to (bar size/9.027)², which is approximated as (bar size/9)² square inches.
For example, in the first week of November, Nucor and Steel Dynamics informed their customers that they would raise prices of merchant bar by $20 a short ton. That matched an earlier increase from ...
Morgan Construction Company has been building high-production, continuous, 2-high hot mills since 1888. These mills were designed to produce wire rod, merchant bars, small angles, skelp, sheet, bar, and billets, and were in operation in practically every country where the manufacture of steel has assumed large enough proportions to warrant this type of mill.
Rebar detailing is the discipline of preparing 'shop/placing' or 'fabrication' drawings or shop drawings of steel reinforcement for construction. Engineers prepare 'design drawings' that develop required strengths by applying rebar size, spacing, location, and lap of steel .
In 1908, the firm continued to expand its facilities. The plant at Indiana Harbor got 3 new sheet mills, 2 galvanizing pots, an 8"-11" merchant mill, and a 24" sheet bar billet and mill. [40] Two open hearth furnaces and 8 sheet mills were added in 1910. Land was leased on the Cuyuna Range in Minnesota for iron ore mining. [40]
A bar is characterised by an "enclosed invariant convex cross-section", meaning that pipes, angle stock and objects with varying diameter are not considered bar stock. Bar stock is commonly processed by a sequence of sawing , turning , milling , drilling and grinding to produce a final product, often vastly different from the original stock.
