Hey there! I'm a supplier of galvanised metal tubing, and I often get asked about the different sizes available. So, I thought I'd put together this blog post to give you the lowdown on all the sizes we've got in our inventory.
Understanding Galvanised Metal Tubing
Before we dive into the sizes, let's quickly go over what galvanised metal tubing is. Galvanised tubing is steel tubing that has been coated with a layer of zinc. This coating helps protect the steel from rust and corrosion, making it a great choice for a variety of applications, from construction and fencing to automotive and furniture manufacturing.
Available Sizes
Round Galvanised Metal Tubing
Round galvanised metal tubing is one of the most common types we offer. It comes in a wide range of diameters and wall thicknesses to suit different needs.
- Diameters: We typically stock round galvanised tubing with diameters ranging from 1/2 inch to 6 inches. The smaller diameters, like 1/2 inch and 3/4 inch, are often used for things like handrails, small frames, and DIY projects. Medium-sized diameters, such as 1 inch to 2 inches, are popular for structural applications in construction and agricultural equipment. Larger diameters, from 3 inches to 6 inches, are commonly used in heavy-duty construction, like building supports and large-scale industrial structures.
- Wall Thicknesses: The wall thickness of round galvanised tubing can vary from as thin as 0.035 inches to as thick as 0.250 inches. Thinner-walled tubing is more lightweight and flexible, making it suitable for applications where weight is a concern. Thicker-walled tubing, on the other hand, offers greater strength and durability, which is essential for heavy-duty applications.

Rectangular Galvanised Metal Tubing
Rectangular galvanised metal tubing is another popular option. It's often used in applications where a flat surface or a specific shape is required.
- Sizes: Our rectangular galvanised tubing comes in a variety of sizes, with common dimensions ranging from 1 inch x 2 inches to 6 inches x 8 inches. The smaller sizes are great for things like furniture frames, display racks, and small-scale construction projects. Larger sizes are used in more substantial construction, such as building frames and structural supports.
- Wall Thicknesses: Similar to round tubing, rectangular tubing also has different wall thicknesses. We offer wall thicknesses from 0.049 inches to 0.250 inches, allowing you to choose the right level of strength for your application.

Square Galvanised Metal Tubing
Square galvanised metal tubing is widely used in a variety of industries due to its uniform shape and strength.
- Sizes: We have square galvanised tubing available in sizes ranging from 1 inch x 1 inch to 8 inches x 8 inches. Smaller square tubing is commonly used for decorative purposes, such as in gates and fences, as well as in small mechanical components. Larger square tubing is used in heavy construction, like building columns and large frames.
- Wall Thicknesses: The wall thickness of square galvanised tubing can range from 0.049 inches to 0.250 inches. As with other types of tubing, the choice of wall thickness depends on the specific requirements of your project.

Choosing the Right Size
When it comes to choosing the right size of galvanised metal tubing for your project, there are a few factors to consider.
- Load Requirements: If your project involves supporting heavy loads, you'll need to choose tubing with a thicker wall and larger dimensions. For example, if you're building a large industrial structure, you'll want to use larger-diameter and thicker-walled tubing to ensure it can handle the weight.
- Space Constraints: In some cases, you may be working in a limited space. In these situations, you'll need to choose tubing that fits within the available space without compromising on strength. For instance, if you're building a small furniture frame, you might opt for smaller-diameter or thinner-walled tubing.
- Aesthetic Considerations: Sometimes, the appearance of the tubing is important. If you're using the tubing for a decorative purpose, you may want to choose a specific size and shape that complements the overall design.
