Mild Steel Angle Galvanised is an angle shaped galvanised Mild Steel.
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.
Galvanised steel is widely used in applications where rust resistance is needed, and can be identified by the crystallization patterning on the surface (often called a “spangle”).

Additional Information
Brass Square Bar CZ121 is a square shaped CZ121 Brass Alloy bar.
CZ121 Brass Alloy is a free-machining brass consisting of a duplex phase structure with a 3% lead content.
It is suited to high speed machining operations due its superior machinability, thread rolling and knurling characteristics.
Particles of lead are finely dispersed throughout the microstructure, acting as both a lubricant and a chip breaker to give the alloy its free-machining characteristics.
CZ121 Brass Alloy’s machinability rating of 100 is the standard against which all copper alloys are rated. It offers good strength, is easily soldered or brazed and has good resistance to corrosion.
