ASTM A653 En10326 Hdgi Dx51d Sg550 SGCC Kub Dipped Galvanized Steel Sheet Aluzinc Galvalume Coated Gi Gp Galvanized Steel Chev rau cov kav dej thiab ru tsev

Lub npe tag nrho ntawm SGCC coil yog dab tsi?
Teb: SGCC coil stands rau Kub-Dip Galvanized Cold-Rolled Steel Chev.
Lub teb chaws twg cov qauv ua SGCC coils ua raws?
Teb: SGCC coils ua raws li Japanese Industrial Standards (JIS), tshwj xeeb yog JIS G3302.
Dab tsi yog cov khoom tseem ceeb ntawm SGCC coils?
Teb: SGCC coils yog raws li hlau (Fe). Nws cov tshuaj muaj pes tsawg leeg suav nrog cov ntsiab lus carbon (C) tsis tshaj 0.15%, manganese (Mn) cov ntsiab lus tsis tshaj 0.80%, phosphorus (P) cov ntsiab lus tsis tshaj 0.05%, thiab sulfur (S) cov ntsiab lus tsis tshaj 0.05%. Cov seem yog hlau thiab ib qho me me ntawm cov impurities uas tsis tuaj yeem zam. Qhov saum npoo yog coated nrog zinc (Zn) txheej los ntawm kev kub -dip galvanizing txheej txheem.
Dab tsi yog qhov tuab ntawm zinc txheej ntawm SGCC coils?
Teb: Lub zinc txheej thickness ntawm SGCC coils feem ntau yog li ntawm 30g / m² mus rau 275g / m², nrog cov thicknesses xws li 80g / m², 120g / m², thiab 275g / m².
Dab tsi yog qhov txawv ntawm SGCC coils thiab SECC coils?
Teb: SGCC coils yog kub-dip galvanized, thaum SECC coils yog electroplated. SGCC coils muaj cov zinc txheej tuab, muab kev tiv thaiv corrosion ntau dua thiab feem ntau tuaj yeem siv yam tsis muaj xim. SECC coils muaj ib qho thinner, ntau txheej zinc txheej, uas ua rau muaj qhov zoo nkauj dua thiab yooj yim tha xim.
