Galvanised – CQ Plate – 0.8mm
Galvanised – Commercial Quality (CQ) Steel Plates : Hot-dip galvanising is the process of coating iron or steel with a thin zinc layer, by passing the steel through a molten bath of zinc at a temperature of around 860 °F (460 °C). When exposed to the atmosphere, pure zinc reacts with oxygen to form zinc oxide, which further reacts with carbon dioxide to form zinc carbonate, a dull grey, fairly strong material that stops further corrosion in many circumstances, protecting the steel below from the elements. Plate thicknesses available from 0.5mm up to 1.2mm.
Overall Size : 2450mm(l) x 1225mm(w)
Thickness : 0.8mm
Weight : 19.3kg per plate
Galvanised steel is widely used in applications where rust resistance is needed and can be identified by the crystallisation patterning on the surface (often called a “spangle”).Galvanised steel can be welded; however, one must exercise caution around the resulting zinc fumes. Galvanised steel is suitable for high-temperature applications of up to 392 °F (200 °C). Use at temperatures above this level will result in peeling of the zinc at the inter-metalic layer. Galvanised sheet steel is commonly used in automotive manufacture to enhance corrosion performance of exterior body panels of some models.
What is “Commercial Quality” Steel?
A designation of a grade of steel suitable for moderate forming processes. Material of this quality is ductile enough to be bent flat on itself in any direction in a standard bending process. The term is commonly used to designate mild steel. Also known as CS (commercial steel) or CQ (commercial quality).
