Galvanised Angle Bars
Galvanised Angle Bar
Galvanised angle bar, also commonly referred to as galvanised angle, galvanised angle iron, is a L-shaped low carbon steel bar with two equal or unequal legs that has been hot dipped in a zinc rich galvanizing process. Galvanised angle bars have great strength and corrosion resistance, therefore they are ideal for all general fabrication and repairs. Galvanised angle bars have also excellent weld performance, formability and machinability. As such, galvanised angle bars are often used in large structural settings such as high-rise buildings, bridges, transmission towers and factories.
Uses of galvanised angle bar include construction, transportation, structural applications, manufacturing, industrial, general fabrication, machining and repairs, transmission line towers and support frames.
Two of the common mild steel grades used for galvanised angle bars are EN10025 S275 and ASTM A36. EN10025 S275 is a popular mild steel grade utilized in various general engineering and construction applications. As a low carbon steel specifications, EN10025 S275 provides moderate strength with good machinability and can be easily welded. Mild steel grade S275 is used widely in the structural applications as it has good weldability and machinability.
Mild steel grade ASTM A36 is another popular and widely used carbon structural steels, which is mild and hot rolled. Grade ASTM A36 steel’s strength, formability and excellent welding properties makes it suitable for different kinds of machining processes. With its superior mechanical properties, ASTM A36 is usually the base material for all general construction and industrial applications. Depending on the thickness and corrosion resistance of the alloy, ASTM A36 mild steel is versatile and can be used for many different applications.

There are two predominant types of galvanised angle bars, hot-dip galvanising and electrogalvanising. For hot-dip galvanising, the steel surface is dipped in molten pure zinc. For zinc plating or electrogalvanising, a thin coating of zinc is applied on a steel surface using an electric current. Electrogalvanising produces a thinner less resilient surface and mostly recommended for interior use.
|Hot-Dip Galvanising||Application of a zinc coating by dipping steel in a molten pool of zinc. Alloy layers such as zinc oxide and zinc carbonate, are formed on the primary metal through reaction with the surrounding atmosphere to form a protect coating.|
|Electrogalvanising||An electrolyte solution is passed through an electric current, which is later applied to the steel. The electric current reduces positively charged zinc ions to zinc metal, which is then deposited on the positively charged steel.|
|Pre-Galvanising||Rolling sheet metal through a cleaning agent to quickly prime material for galvanising. The metal is passed through a pool of molten liquid zinc and is instantly recoiled.|
|Cold Galvanising||Application of zinc-rich paint to the surface of steel metal to protect it from corrosion.|
Other galvanised angle bar sizes and grades are available upon request. You can request to cut your galvanised angle bars down to size.
