Galvanised Angle Bar
Galvanised Angle Bar is a kind of steel bar that has a L-shaped cross section with two legs, either equal or unequal. Angle Bar, also known as angle iron, is widely used in various industries, such as construction, engineering, machinery, manufacturing, and more. Galvanised Angle Bar is made of low carbon steel or high strength low alloy steel, such as Q235B, Q355B, A36, SS400, S355JR, S355J0, etc. Angle Bar has excellent weldability, formability, and machinability properties. It can also resist corrosion and abrasion in different environments.

Product Benefits
Because it can be used for a variety of applications, including water supply, gas transmission, fire protection, fencing, scaffolding, etc., Erw galvanized pipe can satisfy a wide range of customer needs.
Some of the advantages:
- It is cost-effective and durable, compared to other types of steel bars.
- It can provide structural support and reinforcement for various applications, such as bridges, buildings, towers, frames, etc.
- It can be easily cut, bent, drilled, and welded to meet different specifications and requirements.
- It can be coated or painted to enhance its appearance and performance.
