Abstract

This Uganda Standard specifies requirements for continuous hot-dip Aluminium-Zinc (AZ) coated plain and corrugated steel sheets for roofing, cladding, fencing, fabrication and general use. This standard does not cover the special purpose profiles. The Aluminium-Zinc alloy composition by mass is nominally 55 % Aluminium, 1.6% Silicon and balance Zinc. The product is intended for applications where the corrosion characteristics of Aluminium coupled with those of Zinc are most desired. (This standard cancels and replaces US 540:2006 Hot-dip aluminium-zinc plain and corrugated steel sheets- Specification) . This standard was PUBLISHED on 2020-06-16
