ASTM A792/A792M10 Standard Specification for Steel Sheet, 55% Aluminum-zinc Alloy-coated by the Hot-dip Process (PDF Download) Effects of Spangle Size on Performances of Hot-dip Zinc and zinc alloy coatings are two common methods used to prevent the corrosion of steel sheets in atmospheric environment. The most widely used technologies in industrial production are hot-dip pure zinc (hereinafter referred to as GI) and 55%Al-43.4%Zn-1.6%Si alloy coating (hereinafter referred to as GL) steel sheets.
Refer to GalvInfoNote 2.4 for a discussion of a similar, but thinner, intermetallic layer that forms when steel is zinc-coated using the hot-dip process). As with hot-dip galvanized sheet, controlling the interaction between the steel sheet and the molten coating during the manufacturing process is vital to achieve good adhesion of the coating during eventual forming operations by the customer. Galvalume® vs. Galvanized Metal Roofing :ABC BlogJun 14, 2016 · Introduced into the construction marketplace by Bethlehem Steel in 1972 and now widely available around the world, Galvalume ® is carbon steel sheeting coated with aluminum-zinc alloy by a continuous hot-dip process. Composed of 55 percent aluminum and approximately 45 percent zinc, this coating combines the best properties of both metals. IS 15961 (2012):Hot Dip Aluminium-Zinc Alloy Metallic The un-altered 55 percent aluminium zinc crystal structure that occurs during solidification of a hot-dip coated steel sheet. It will be denoted by N (Normal). 3.5.2 Skin Passed The material is skin passed for improved surface condition to make it suitable for subsequent painting and it will be denoted by S (Skin passed). 3.6Coating Class The designation of coating class shall include a set of characters as
ISO 9364:2017 is applicable to the requirements for steel sheet, in coils and cut lengths, metallic-coated by the continuous hot-dip process with 55 % aluminium-zinc alloy coating. The product is intended for applications requiring the corrosion characteristics of aluminium coupled with those of zinc, or heat resistance, or both. ISO/DIS 9364(en), Steel sheet, 55 % aluminium-zinc alloy This document is applicable to the requirements for steel sheet, in coils and cut lengths, metallic-coated by the continuous hot-dip process with 55 % aluminium-zinc alloy coating. The product is intended for applications where the corrosion characteristics of aluminium coupled with those of zinc are desired. Properties of a 55% Aluminium-Zinc Coating on Steel The aluminiumzinc (AZ) coating on steel sheeting consists of nominally 55 % aluminium, 43,4 % zinc and 1,6 % silicon, and it is applied by hot dipping in a molten bath.
