Understanding the Difference Between Wrought and Cast Iron Trellis

One of the common mistakes people often make is using the term cast iron trellis and wrought iron trellis interchangeably. The truth is, these two are not the same. Although they are both commonly used as iron wall trellis, they both undergo a different process and offer different benefits.

Understanding the difference between these two materials helps you determine which one is more suitable for your purpose. Making an informed decision is the primary key to finding lasting materials that you can use for your home improvement projects. To help you get started exploring the differences between these two, check out the information provided below:

Wrought and Cast Iron Trellis – How Are They Different?


One of the primary differences between these two materials is how they are shaped and formed according to your preference.

Cast iron trellis are formed by changing it into liquid metal first and then pouring it into a mold container. The liquid metalthen takes the shape or the design of the container. Then you have to wait for it to solidify to see that it has perfectly adapted the design of your molder.

Wrought iron trellis on the other hand, is manually shaped and designed. It requires constant heating, pounding and shaping until your desired design is finally achieved.


Between wrought and cast iron trellis, wrought is more malleable.

Wrought can withstand high temperatures and pressure by simply changing its form without breaking. This is the reason why it can be shaped and designed using heat, force and pressure without any problem. As a result, you get more design options.

Cast iron on the other hand has low malleability. Exposing this material in the same process as wrought won’t cause the cast iron to change its shape. Instead, it will start to break, which is the reason why it has to be melted and shaped using cast or mold container.


Cast iron trellis is relatively cheaper than the wrought iron trellis.

One of the primary reasons why cast iron trellis is much cheaper is because the process involved in processing cast iron or for shaping and designing cast iron is much faster, requires lesser resources and manpower.

Wrought iron trellis are more expensive compared to cast iron. This can be attributed to the resource intensive process involved in shaping and designing wrought iron. It requires a lot of manpower, more tools and long work hours to complete. However, the beauty of choosing this material is your trellis design is not limited to the type of mold or cast that you have, instead it can go as far as the creativity of the blacksmith working on your iron trellis.


Both require routine maintenance. Since both wrought and cast iron trellis are susceptible to rust, it is highly recommended that you apply or use rustproof paint to keep them protected. However, through time this protective covering tends to fade or flake away, especially when used outdoors, so you have to make sure that you do routine checks and new rustproof application.

The details provided here are just some of the things that you have to take note when considering wrought or cast iron trellis.
