About Square Metal Tubing

Square metal tubing is a hollow metal product with equal-length sides and consistent wall thickness throughout. Compared to solid bars, tubing offers an excellent strength-to-weight ratio, making it a practical choice for many structural and functional applications.

Square tubing is valued for its clean, modern appearance and its ability to resist twisting or bending under load. It is commonly specified when designers or engineers want sharp lines, uniform dimensions, and reliable performance.

At Polished Metals, our extensive inventory and advanced finishing equipment allow us to process square metal tubing to a wide range of specifications, sizes, and surface finishes. Whether your project requires a mirror polish, satin finish, or custom surface treatment, we can deliver tubing that meets your exact requirements.

Industry Use Cases

Finished square metal tubing is used across many industries for both functional and aesthetic purposes. Below are some of the most common applications.

Architecture and Design

In architectural and interior design projects, square metal tubing is often used for visible elements where clean geometry and finish quality are important. Common uses include railings, frames, partitions, furniture components, and decorative accents. Polished or brushed finishes help elevate the overall look while maintaining durability.

Construction and Engineering

Square tubing is a staple in construction and engineering due to its strength, consistency, and ease of fabrication. It is frequently used for structural frames, supports, and bracing. Depending on the metal selection, square tubing can also perform well in corrosive environments or applications that require long-term durability.

Elevators and Escalators

Square metal tubing is widely used in elevator and escalator systems, including cab frameworks, structural supports, safety features, and trim components. Finished tubing is especially valuable in visible areas, where both performance and appearance are critical.

Square Metal Tubing: Common Metal Choices

Several metals are commonly used for square metal tubing, each offering distinct advantages depending on the application.

Stainless steel is one of the most popular choices for all types of tubing due to its strength, corrosion resistance, and clean appearance. It is well suited for both structural and architectural uses, especially in high-traffic or moisture-prone environments.
Aluminum is lightweight, corrosion resistant, and easy to fabricate. Aluminum tubing is ideal for applications where weight reduction and ease of handling are important.
Brass and bronze are often selected for architectural and decorative square tubing applications. These metals offer distinctive color, corrosion resistance, and a premium appearance, particularly when polished or satin finished.

Choosing the right metal for square tubing depends on factors such as structural requirements, exposure to the elements, budget, and aesthetic goals.

They have been a consistent, reliable vendor for me both in regards to informational needs and as a product supplier. Quotes are often required to be turned around by me very quickly and Bob Gunther at Polished Metals sends me pricing and lead-times extremely fast. Our product arrives when we are told it will and if there are any delays (which does not happen often) we are informed ahead of time, which is appreciated.

“Polished Metals has been a Preferred Vendor of ours for over a decade. Our corporate philosophy dictates that we have Alternate or Secondary Supplier for all product, with the exception of #8 Mirror Polished Stainless Steel. We’ve tried to qualify other suppliers to no avail, as none of them can compete in any of the critical categories. The Customer Support provided by Bob Gunther cannot be replicated, pricing is fair, delivery is always on-time and quality is fantastic. As the Corporate Purchasing Manager for the last 7 years, not once have I had a negative experience with Polished Metals. I can’t say enough good things about them.”
