How to choose the right metal for your project
So, you’re starting a new metal project and you need help choosing the right metal for the job – and back pocket. Usually, choosing a readily available metal with a good range of properties is the best place to start.
Thankfully, Clickmetal offers a cut-to-size service for a some of the most popular metal choices, including aluminium, stainless steel, galvanised steel, and mild steel. But which type of metal is right – and what shape should you choose? In this guide we explain the properties and shapes of common metals to help you decide.
How to choose the right metal shape for your project
Not sure which metal shape is right for your project? Here’s some information on the different shapes:

Flat barsFlat bars are easy to bend into specific curves and they can also easily bend around other axis. With the right drilling equipment, it’s easy to bolt flat bars to each other and other objects. |

Angle IronIf you’re looking to create a rim or a collar off a flat metal plate – a wheel rim is a good example – angle iron is the best shaped metal for the job. |

C-channelSome c-channel bars can come with holes already installed making them super-convenient for bolting. They also help with the structural strength of the piece of metal you’re bolting it to. |

Metal tubesThanks to their four sides, metal tubes are the strongest metal structures going, making them the best choice if your project requires rigid structural integrity. |
Choosing the right metal shape for your project is integral to its success. At Clickmetal, we stock specific angles, tubes, tee sections, and bars, so you can order the right metal shape for your project.
How to choose a metal with the right properties
There are four ways to define metal properties. These are:
- Formability – how easy it is to form the metal into different shapes
- Weldability – how easy the metal is to weld
- Machinability – how easy it is to cut the metal with a blade
- Tensile strength – how easy it is to snap the metal
At Clickmetal, we stock aluminium, stainless steel, galvanised steel, and mild steel. But which one has the right properties for your project?

What are the pros and cons of aluminium, stainless steel, and galvanised steel, and mild steel?
|
|
Pros |
Cons |
|
Aluminium |
Practical and lightweight Rust resistant Easy to machine Ready available
|
Requires skill to weld Not as cost effective as steel |
|
Stainless steel |
Won’t rust unless exposed to acid from chrome or nickel Easy to recycle Extremely durable Aesthetically shiny and clean
|
Heavy Not particularly easy to manipulate Not easy to weld – warps if correct techniques aren’t used |
|
Galvanised steel |
Corrosion resistant Durable More affordable than stainless steel Easy to maintain |
Less visually appealing than stainless steel Zinc can wear off Can become brittle over time
|
|
Mild steel |
Cost-effective Malleable Weldable |
Vulnerable to rust and corrosion Low tensile strength |
