Hot Rolled Sheet Metal Thickness

There are other measurement units used to categorise metals by thickness though.

Hot rolled sheet metal thickness. Hot rolled steel starts as a large rectangular length of metal called a billet. 0 7 mm 0 8mm and 1 5 mm. Gague are used to specify the thickness of a metal sheet. As the metal sheet gets thinner between the rolls its speed increases.

High strength and highly formable hr steel sheet and plate is also easy to drill form and weld. For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick. Kynar galvalume steel for metal roofing and gutters. 0 027 or 0 032 for seamless gutters and any other thickness for custom gutters.

When galvanized it is also regularly used in applications where corrosion resistance is a necessity. Conversion data chart standard gauges chart gauge tolerance chart useful data page. 7 gauge 0 1783 in. Sheet metal is one of the shapes and forms metal can be bought in.

7 gauge 0 1783 in. Hot rolled steel sheet and plate provides a rougher surface than cold rolled steel and plate. The metal is rolled to the thickness of 0 5 3 mm in case of mild steel and 0 5 5 mm in case of stainless steel. Some metal forming processes allow for more precision than others.

The material is cooled by the use of oil which also acts as a lubricant during the rolling process. Thicknesses beyond this point are considered to be plate. There are several different gauge systems used today with specific gauge designations used for specific metal types. Sheet metal is any metal that has a thickness in between 0 5 6 millimetres.
