The cold rolled steel tube describes the process quite well: steel stock passes through a series of rollers, to be flattened out and reshaped as steel tubing. However, the steel remains at room temperature as its processed. It is a seamless steel tube for high dimensional accuracy and good surface finish. Cold rolled steel is essentially hot rolled steel that has had further processing. It begins as hot rolled steel but is processed even further to create a more finished surface and provide additional strength. Cold rolled steel tube is very durable.
