Understanding 1 1/2 x 3 1/2 Rectangular Tubing

1 1/2 x 3 1/2 rectangular tubing, also known as 1.5" x 3.5" rectangular tubing, is a versatile and commonly used structural material. It's a hollow rectangular profile with an outer dimension of 1.5 inches by 3.5 inches, and it's available in various wall thicknesses and materials.

Common Applications

This type of tubing finds its way into numerous applications, including:

  • Construction: Building frames, structural supports, and fencing.
  • Manufacturing: Machinery components, machine frames, and industrial equipment.
  • Automotive: Chassis components, roll cages, and custom fabrication.
  • Furniture: Tables, chairs, and other furniture structures.
  • Art and Design: Sculptures, decorative elements, and custom projects.

Advantages of Using 1 1/2 x 3 1/2 Rectangular Tubing

  • Strength and Durability: Its rectangular shape provides excellent strength and rigidity compared to round tubing.
  • Lightweight: Being hollow, it offers good strength-to-weight ratio, making it ideal for applications where weight is a concern.
  • Versatility: Its rectangular profile allows for easy welding, cutting, and bending, making it versatile for various projects.
  • Cost-effectiveness: It is generally more affordable than other structural materials with similar strength.

Choosing the Right Material

1 1/2 x 3 1/2 rectangular tubing is available in various materials, each with its own properties and suitability for specific applications:

  • Steel: Strong, durable, and widely available. It's a popular choice for structural applications.
  • Aluminum: Lightweight, corrosion-resistant, and easy to work with. Ideal for applications where weight is a concern.
  • Stainless Steel: Offers excellent corrosion resistance, making it suitable for outdoor applications.
  • Other Materials: Materials like copper, brass, and titanium are available depending on specific project needs.

Selecting the Right Wall Thickness

The wall thickness of the tubing is crucial for determining its strength and weight. A thicker wall provides greater strength and rigidity, but also increases weight. Thinner walls are lighter but offer less strength. The choice depends on the specific application and required load-bearing capacity.


1 1/2 x 3 1/2 rectangular tubing is a versatile and reliable structural material used in a wide range of applications. Its strength, durability, and affordability make it a popular choice for builders, manufacturers, and hobbyists alike. By understanding its properties and applications, you can make informed choices when selecting the right material and wall thickness for your specific needs.
