  2. Hot-dip galvanization - Wikipedia

    en.wikipedia.org/wiki/Hot-dip_galvanization

    Hot-dip galvanized steel strip (also sometimes loosely referred to as galvanized iron) is extensively used for applications requiring the strength of steel combined with the resistance to corrosion of zinc, such as roofing and walling, safety barriers, handrails, consumer appliances and automotive body parts.

  3. 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.

  4. PPGI - Wikipedia

    en.wikipedia.org/wiki/PPGI

    PPGI is pre-painted galvanised iron, also known as pre-coated steel, coil coated steel, color coated steel etc., typically with a hot dip zinc coated steel substrate.. The term is an extension of GI which is a traditional abbreviation for Galvanized Iron.

  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. Structural steel - Wikipedia

    en.wikipedia.org/wiki/Structural_steel

    The terms angle iron, channel iron, and sheet iron have been in common use since before wrought iron was replaced by steel for commercial purposes. They have lived on after the era of commercial wrought iron and are still sometimes heard today, informally, in reference to steel angle stock, channel stock, and sheet, despite that they are ...

  7. Galvannealed - Wikipedia

    en.wikipedia.org/wiki/Galvannealed

    In comparison to a zinc (galvanized) coating galvannealed has better spot weldability, and is paintable, [4] Due to iron present in the surface alloy phase galvanneal develops a reddish patina in moist environments - it is generally used painted. [5] Zinc phosphate coating is a common pre-painting surface treatment. [4]

  8. Strut channel - Wikipedia

    en.wikipedia.org/wiki/Strut_channel

    Strut is normally made of sheet steel, with a zinc coating (), paint, epoxy, powder coat, or other finish.. Strut channel is also manufactured from stainless steel for use where rusting might become a problem (e.g., outdoors, facilities with corrosive materials), from aluminium alloy when weight is an issue or from fiberglass for very corrosive environments.
