  The Benefits of Aluminium-Zinc Coated Steel   AZ vs GI coatings   Aluminium-zinc coating The mild steel substrate is continuously hot dipped in a formulation of Aluminium (55%), Zinc (43.5%) and Silicon (1.5%). The process of applying an Aluminium-Zinc alloy in a hot dip delivers superior oxidation-resistance therefore extending the service lifespan of a steel roof by up to four times that of galvanised steel. Galvanised coating Offering some defence against corrosion-causing elements, galvanised metal is a sheet of steel which has been coated with a thin layer of Zinc oxide (99.8% Zinc). Galvanising offers almost twice the service life of the steel substrate. Notable differences There is a visible difference between the two coatings as an Aluminium-Zinc alloy metal appears to almost have a matte finish while galvanised steel has a unique shiny spangle appearance. Galvanised metal corrodes linearly, and eventually, the Zinc coating is completely depleted, whereas an Alu...

  Aluminum is a material widely used in the production of automobiles, aircraft, panels, construction and packaging components. In addition, aluminum can be coated with different substances or paints to increase its durability and attractiveness and to make it more durable. There is a wide range of  aluminum coatings  that were created according to the needs of customers and market trends. In fact, by surface coating we are not only referring to the industrial process of applying a coating on ACP. There are two main reasons for selecting a specific type of coating: to protect the material being coated and to improve its aesthetic and functional properties. For this reason, the type of coating varies depending on the end goal and the application area.   TZ1600-40 Double Sides & Double  Coatings Line   Aluminum coil pretreatment The surface of the coil is cleaned of oil and impurities by means of chemical cleaning agents and chemical conversion solvents, ...
