What is Rectangular Tubing? Everything You Need To Know

Rectangular tubing is one of the must-have materials for several projects due to its versatility and strength. It is also a go-to choice for fabricators, artists, hobbyists, machine shops, and DIY enthusiasts. Whether you’re constructing furniture, creating art installations, or building structural components, rectangular tubing offers a range of benefits that make it a valuable addition to your toolkit.

What is Rectangular Tubing?

Rectangular tubing is a hollow, rectangular-shaped bar made from metallic or plastic materials. Unlike its round or square counterparts, its rectangular shape offers unique advantages for various creative and functional projects. Whether building custom furniture, crafting sculptures, or tackling home improvement challenges, rectangular tubing provides a sturdy yet easily workable foundation. Its appeal to artists, fabricators, and machine shops lies in its strength, ease of manipulation, and aesthetic flexibility. Available in various sizes and materials, it’s perfectly suited for anyone looking to bring their innovative ideas to life with precision and style.

Types of Rectangular Tubes

Here are types of rectangular tubes you can purchase from trusted metal suppliers like FastMetals:

Carbon Steel Rectangular Tubes

Carbon steel rectangular tubes are known for their strength and durability, making them a popular choice for structural projects that require a sturdy framework. With a higher carbon content than other steel types, these tubes can handle a lot of wear and tear, making them ideal for outdoor structures, garden frames, or any project where strength is a priority. Their robust nature, however, means they are heavier and might be prone to corrosion if not properly treated or painted.

Stainless Steel Rectangular Tubes

Stainless steel rectangular tubes offer a sleek, modern look and resistance to corrosion and staining, as compared to carbon steel. This makes them perfect for projects that demand both aesthetic appeal and longevity, such as outdoor furniture, railings, and art installations exposed to the elements. Stainless steel’s resistance to high and low temperatures also makes it suitable for projects involving extremes in temperature, offering reliability and durability in challenging environments.

Aluminum Rectangular Tubes

Aluminum rectangular tubes are lightweight, making them easy to work with, especially for projects that require a lot of maneuvering or where weight is a concern, like mobile art pieces or custom automotive modifications. Despite their lightness, they provide considerable strength and corrosion resistance, which makes them ideal for indoor and outdoor applications. Their malleability allows for creative customizations, perfect for hobbyists looking to push the boundaries of their creative projects.

Brass Rectangular Tubes

Brass rectangular tubes stand out for their distinctive color and natural resistance to corrosion. They offer a unique aesthetic that’s particularly appealing in artistic projects, custom furniture, or decorative elements in home renovations. Brass is also known for its antimicrobial properties, making it a smart choice for surfaces in frequently touched areas. Brass rectangular tubings offer a good balance of workability and durability, suitable for projects where aesthetics are just as important as functionality.

6 Benefits of Rectangular Tubes

1. Strength and Durability

Rectangular tubing is known for its exceptional strength and durability. Its rectangular shape distributes weight evenly, allowing it to withstand higher pressures and loads than other shapes. This makes it an ideal choice for structures requiring a robust framework, ensuring longevity and reliability in indoor and outdoor settings.

2. Versatility in Applications

The versatility of rectangular tubes is unmatched. They can be used in everything from constructing custom furniture and home décor to creating robust frames for garden structures. Their ease of welding, cutting, and drilling opens up endless possibilities for hobbyists, artists, and DIY enthusiasts to explore creative and functional projects.

3. Aesthetic Appeal

Rectangular tubing has a sleek, modern appearance that enhances the aesthetic value of any project. Its clean lines and smooth finish can complement various designs, from minimalist to industrial chic, making it popular for home décor, furniture, and art installations.

4. Ease of Installation

The straightforward shape of rectangular tubing makes it easy to work with, cutting down on installation time and effort. Whether you’re assembling a shelving unit or putting together a frame for a greenhouse, its uniformity allows for simple alignment and connection, making projects more manageable for DIYers of all skill levels.

5. Cost-Effectiveness

Despite its many advantages, rectangular tubing remains affordable for various projects. Its durability and low maintenance requirements contribute to its cost-effectiveness, ensuring that your projects look great and are economical in the long run.

6. Customization and Adaptability

Customization is straightforward with rectangular tubing available in various sizes, thicknesses, and materials. Whether your project needs lightweight aluminum for easy mobility or robust steel for structural support, a rectangular tube fits the bill. This adaptability allows for tailored solutions, ensuring that each project can be completed to meet specific requirements and preferences.

How Rectangular Tubing is Made?

There are three primary methods for manufacturing rectangular tubing:

1. Seamless Method

Seamless tubing is made by extruding steel into a rectangular shape without welding. This process creates a tube with consistent strength and a smooth surface, ideal for projects where aesthetics and structural integrity are key. Think of seamless tubing for sleek furniture designs, custom automotive parts, or any high-pressure application requiring a flawless finish.

2. As-Welded Tubing

As-welded (or electric-resistance welded [ERW]) tubing is formed by bending steel strips into a rectangular shape and welding the seam. This cost-effective method allows for a wide range of sizes and shapes. As-welded tubing is versatile and suitable for general projects like garden structures, decorative frames, and practical uses where the seam’s presence is not a detractor.

3. Drawn-Over-Mandrel (DOM)

The DOM process involves welding the tube and then drawing it over a mandrel to refine its dimensions and surface. This results in tubing with improved dimensional accuracy, uniform wall thickness, and enhanced strength. DOM tubing is perfect for projects requiring precision, such as custom mechanical parts or detailed artistic creations where every detail matters.
