2. Prepainted metal - Wikipedia

   en.wikipedia.org/wiki/Prepainted_metal

   The metal substrate (steel or aluminum) is delivered in coil form from the rolling mills. Coil weights vary from 5-6 tons for aluminum and up to about 25 tons for steel. The coil is positioned at the beginning of the line, then unwound at a constant speed, passing through the various pre-treatment and coating processes before being recoiled.

3. Electrogalvanization - Wikipedia

   en.wikipedia.org/wiki/Electrogalvanization

   Dedicated to plating at high speed in plants where the shortest plating time is critical (i.e. steel coil or pipe that runs at up to 200 m/min. The baths contain zinc sulfate and chloride to the maximum solubility level. Boric acid may be used as a pH buffer and to reduce the burning effect at high current densities.

4. PPGI - Wikipedia

   en.wikipedia.org/wiki/PPGI

   PPGI refers to factory pre-painted zinc coated steel, where the steel is painted before forming, as opposed to post painting which occurs after forming. The hot dip metallic coating process is also used to manufacture steel sheet and coil with coatings of aluminium, or alloy coatings of zinc/aluminium, zinc/iron and zinc/aluminium/magnesium ...

5. Corrugated galvanised iron - Wikipedia

   en.wikipedia.org/wiki/Corrugated_galvanised_iron

   Corrugated galvanised iron (CGI) or steel, colloquially corrugated iron (near universal), wriggly tin (taken from UK military slang), pailing (in Caribbean English), corrugated sheet metal (in North America), zinc (in Cyprus and Nigeria) or custom orb / corro sheet (Australia), is a building material composed of sheets of hot-dip galvanised ...

6. Galvannealed - Wikipedia

   en.wikipedia.org/wiki/Galvannealed

   Production of galvannealed sheet steel begins with hot dip galvanization of sheet steel. After passing through the galvanizing zinc bath the sheet steel passes through air knives to remove excess zinc, and is then heated in an annealing furnace for several seconds causing iron and zinc layers to diffuse into one another causing the formation of zinc-iron alloy layers at the surface.

7. Hot-dip galvanization - Wikipedia

   en.wikipedia.org/wiki/Hot-dip_galvanization

   Galvanised hand rail Crystalline surface of a hot-dip galvanized handrail, known as "spangle" Protective effect: completely rusted letter box mounted to a hot-dip galvanized wall Steel strip coming out of the zinc pot of a continuous vertical hot-dip galvanizing line. Hot-dip galvanization is a form of galvanization.

8. Galvanization - Wikipedia

   en.wikipedia.org/wiki/Galvanization

   Galvanized surface with visible spangle. Galvanization (also spelled galvanisation) [1] is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are coated by submerging them in a bath of hot, molten zinc. [citation needed]

9. Electrical steel - Wikipedia

   en.wikipedia.org/wiki/Electrical_steel

   The magnetic properties of electrical steel are tested using the internationally standard Epstein frame method. [18] The size of magnetic domains in sheet electrical steel can be reduced by scribing the surface of the sheet with a laser, or mechanically. This greatly reduces the hysteresis losses in the assembled core. [19]
