Galvanization. Galvanized surface with visible spangle. Galvanization or galvanizing (also spelled galvanisation or galvanising) [1] is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are coated by submerging them in a bath of hot, molten ...
Mangle (machine) A Norrahammars Bruk, model 3005-2, mangle from 1934. A mangle[1] is a mechanical laundry aid consisting of two rollers in a sturdy frame, connected by cogs and (in its home version) powered by a hand crank or by electricity. Mangles are used to press or flatten sheets, tablecloths, kitchen towels, or clothing and other laundry.
Rolling (metalworking) In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of ...
Corrugated galvanised iron. Typical corrugated galvanised iron appearance, with visible large flake type patterns. The galvanised sheet is viewed from below and is supported by a piece of angle iron (painted white). Corrugated galvanised iron (CGI) or steel, colloquially corrugated iron (near universal), wriggly tin (taken from UK military ...
Bending (metalworking) Bending. A chimney starter, a sample product of bending. Bending is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly sheet metal. [1] Commonly used equipment include box and pan brakes, brake presses, and other specialized machine presses.

Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur, and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon, and vanadium are added to produce different ...
The hard-way would be bending the workpiece in the orientation where its moment of inertia is the greatest. The easy-way is bending the workpiece along the axis with the smallest moment of inertia. For example, a piece of angle iron rolled the easy-way would be rolled along one of its flanges, while the hard-way would be along the angle itself.
