Minimized Spangle - Characteristics of the crystal structure due to the restricted growth of zinc crystals during normal solidification, good appearance after painting due to uniformity of the surface, and better paintability compared to regular spangle.
Zero Spangle - Difficult to check the crystal grains with naked eyes due to complete suppression of the surface and outstanding appearance.
Extra smooth - Smooth surface by temper rolling after the solidification.
Good appearance after painting due to surface smoothness.
Standard Packing
Special care is given to prevent abrasion, rust and scratch during transportation and shipment, the procedures are illustrated as follows.
Unit weight is usually 2-5mt for sheet, 4-20mt for coils upon to the request.
