Mild Steel expanded Metal

Mild or plain steel is widely used and relatively inexpensive. It is strong and although it easily corrodes, it is very durable.

Mild steel has a low carbon content (up to 0.3%) and is therefore neither brittle nor ductile, making it suitable for welding, bending, forming and general engineering applications.

Due to its poor corrosion-resistance, mild steel it must be painted or otherwise protected and sealed in order to prevent rust from damaging it. A light coating of oil or grease can help control rust.

It is darker in colour to stainless steel.

It is commonly used for fire guards and other engineering projects.
