BothGALVALUME and galvanized sheet steels are made by a "continuous hot dip" process. Coils of cold rolled steel are welded end-to-end and processed continuously on the coating line at speeds up to 600 feet per minute. The uncoiled sheet is first cleaned to remove rolling oils and mill dirt, and to reduce surface oxides so that the surface will accept the coating. These continuous sheets are first...

The possibilities for using steel in buildings and infrastructure are limitless. The most common applications are listed below.For buildingsStructural sections: these provide a strong, stiff frame for the building and make up 25% of the steel use in buildings.Reinforcing bars: these add tensile strength and stiffness to concrete and make up 44% of steel use in buildings. Steel is used because it b...

Many elements and materials go through chemical reactions with other elements. When steelcomes into contact with water and oxygen there is a chemical reaction and the steel begins to revert to its original form - iron oxide.In most modern steel applications this problem is easily overcome by coating. Many different coating materials can be applied to steel. Paint is used to coat cars and enamel is...
