Rolled Prepainted galvannized Steel coils PPGI colis for galvanized sheetsProduct description:PPGI is pre-painted galvanised steel, 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 Galvanised Iron. Today the term GI typically refers to essentially pure zinc (>99%) continuously hot dip coated steel, as opposed to batch dip processes. 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 which may also be factory pre-painted. While GI may sometimes be used as a collective term for various hot dip metallic coated steels, it more precisely refers only to zinc coated steel. Similarly, PPGI may sometimes be used as a general term for a range of metallic coated steels that have been pre-painted, but more often refers more precisely to pre-painted zinc coated steel.PPGL is similar as PPGI, which L refers to Galvalume, which the steel thus produced in this process is a prepainted, prefinished and ready for further processing into finished products or components. The coil coating process may be used for other substrates such as aluminium, or aluminium, stainless steel or alloy coated steel other than "pure" zinc coated steel. However, only "pure" zinc coated steel is typically referred to as PPGI. For example, PPGL may be used for pre-painted 55%Al/Zn alloy-coated steel (pre-painted GALVALUME(r) steel*)Pre-painted SeriesPPGI COIL SERIESREGULAR POLYESTER PRE-PAINTED COILHIGH POLYMER PRE-PAINTED COILHIGH DURABLE POLYESTER PRE-PAINTED COILPOLYVINYLIDENE FLUORIDE PRE-PAINTED COILSILICONE-MODIFIED POLYESTER PRE-PAINTED COILMATT ROUGH PRE-PAINTED COILSOLAR REFLECTIVE PRE-PAINTED COILPRINTED PRE-PAINTED COILANTI-STATIC PRE-PAINTED COILCOLD STORAGE USAGE PRE-PAINTED COILSPECIFICATIONS:THICKNESSCOIL WIDTH COIL INNERCOIL OUTERCOIL WEIGHT0.12~1.5mm600~1200mm508/610mm800~1500mmmax 6 TonsPRODUCT STANDARDS:1, GB/T2518-2004,01,02,032, EN10142:2000; EN10327:2004; DX51D+Z; DX52D+Z3, JIS G 3302-1998, SGCC, SGCD14, ASTM A653 / A653M, CS(A,B,C), FS(A,B)5, ISO 3575: 1996(E), 01, 02, 032 Structure Show and Common ColorNormal Coating Performance Testing Standards:TEST ITEMSURFACE STANDARDBACK STANDARDDry Film Thickness15 ~ 20 µm8 ~ 10 µmGLOSS (60°)high: 60±5; medium: 40±5 low: 30±530 ± 5T-BENDING3T3TIMPACT J96ACID RESISTANCEsoak in 5% HCL solution for 240 hours without discoloration andwith wrinkling and loss of glossRESISTANCE TO SALT SRAY500Remarks: Other customization and quote shall be offered based on the parameters of actual products if they are not products of normal specification.Our service:(1)One professional sales team will offer you full set service,no matter before or after-sales;(2)One rich experienced engineer and design team can offer you professional advice for both connection technology and building designs;(3)We are manufacturer,and surely can offer you competitive price for you projects. url:http://www.chinasteelmaterial.com
