Types of aluminium roofing sheet

  There are three basic types of aluminium roofing sheet: brushed corrugated aluminium roofing sheet, oxidized aluminum roofing sheet and ps aluminium roofing sheet.

  Brushed aluminium roofing sheet

  The manufacturing process is to repeatedly scrap the corrugated aluminum sheet with sandpaper. The main steps of the process are de-esterification, sanding machine and water washing. In the corrugated aluminum plate drawing process, the special film technology after the anodizing process can form a film layer containing the metal component on the surface of the sheet, clearly showing each fine silk mark, thereby making the metal matte finer and shiner.

  Oxidized aluminum roofing sheet

  This is a corrugated aluminum roofing sheet formed by electrolyzing a corrugated aluminum plate in an electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as an anode under specific conditions and an applied current. The corrugated aluminum plate of the anode is oxidized, and a thin layer of aluminum oxide is formed on the surface, and the thickness thereof is 5 to 20 μm, and the hard anodized film is 60 to 200 μm.

  Mirror aluminum roofing sheet

  This refers to corrugated aluminum sheet which is treated by rolling, grinding and other methods to make the surface of the sheet surface mirror effect.

  Embossed aluminium roofing sheet

  The embossed corrugated aluminum plate can also be called embossed aluminum roofing sheet. It belongs to the aluminum embossed plate on the basis of the corrugated aluminum plate, and the aluminum product formed on the surface by calendering processing is widely used, mainly used in packaging, construction, curtain wall and the like.
