Metal Defects

If you buy something and there is something wrong with it we say that it has a defect.   When steel is delivered to a factory there can be a number of problems.   Here is a short list of things that could be wrong with the metal.

Dents.   Dents are marks on steel caused by a large amount of force hitting a small area.   An example would be if you hit a body panel on a car with a hammer. 

Rust.   This is one of the most common.   Over time moisture in the air will cause most metals to rust and turn a brownish orange colour.   

Necking.    This happens during a stamping process where metal becomes stretched too thin.

Burrs.   When cutting metal sometimes a rough edge forms.   These rough edges are called burrs.   They need to be smoothed out with a grinder or some other tool as they may be unsafe or cause damage to other surfaces they come into contact with.
