With the increasing application of film-coated steel plates, color steel rolling shutter doors have been recognized by the public. Because of its advantages such as fire partition, beautiful appearance, economical and practical, this product has been well used in many places. In order to better connect with the market, and at the same time to meet the diversified needs of the market and better expand into new fields, we are actively developing various types of film-coated steel sheets for rolling shutter doors.
Coated steel plate is a kind of color steel. There are several types of traditional coated steel plates. Different color films have different effects and can be rotted for almost 20 years. It is generally distributed from steel mills to various places in the form of reels. The film-coated steel plate we often see refers to the processed plate with a thickness of about 50~mm. It is composed of a filler in the middle and color steel plates on both sides. Among them, the thickness of the steel plate has different thicknesses such as 0.4mm, 0.5mm, 0.6mm, and the middle layer can be polyurethane, rock wool or foamed plastic. Due to the presence of profiles, the construction speed of workshops constructed of steel plates is very fast (such as the Xiaotangshan Hospital during SARS).
A material will be tested for physical properties during production, and the coated steel plate for door panels is no exception. After cupping, bending, stamping, salt spray and other experiments, the various properties of the steel plate can be used to the greatest extent. , and enhance the service life.
