1-3/4″ X 1-3/4″ X 11 Gauge Steel Square Tube 48″ by Harness Machine

Description

Product Overview

The 1-3/4″ X 1-3/4″ X 11 gauge steel square tube is engineered for strength, precision, and versatility. Measuring a full 48 inches in length, this tube provides a substantial span for structural frameworks, support brackets, and custom fabrication projects. Constructed from high‑grade carbon steel, the tube offers excellent tensile strength while maintaining a manageable weight for ease of handling. The square cross‑section delivers uniform load distribution, making it ideal for both heavy‑duty industrial applications and detailed DIY builds. Harness Machine, a trusted name in metal fabrication, ensures each piece meets strict quality standards, with tight tolerances and a smooth, finished surface that reduces the need for additional machining. Whether you are assembling a machine frame, building a workbench, or creating a custom enclosure, this tube serves as a reliable foundation that can be welded, bolted, or machined to fit your exact specifications.

Usage

This steel square tube excels in a variety of environments. In industrial settings, it is commonly used for constructing machine frames, conveyor supports, and safety guards where rigidity and durability are paramount. Its 11‑gauge thickness provides resistance to deformation under load, making it suitable for high‑stress applications such as robotic arms, automation equipment, and heavy‑duty shelving. For the DIY enthusiast, the tube is perfect for building sturdy workstations, custom tool racks, and outdoor structures like pergolas or garden trellises. The 48‑inch length offers a convenient size that can be cut to shorter lengths without compromising structural integrity, allowing for modular designs and rapid prototyping. Additionally, the tube’s smooth finish facilitates easy welding and bolting, reducing preparation time and ensuring clean, professional results. Whether in a manufacturing plant, a workshop, or a home garage, this tube provides the confidence of a solid, dependable component.

FAQ

What is the recommended method for cutting this steel tube?

The tube can be safely cut using a standard metal chop saw, band saw, or an abrasive cutting wheel. For the cleanest edge, we recommend a cold‑cutting method with a fine‑toothed blade, followed by deburring the cut surface to remove any sharp edges.

Can this tube be welded without additional preparation?

Yes, the tube’s smooth finish is suitable for welding out of the box. However, for optimal weld penetration and strength, it is advisable to clean the area with a wire brush or grinder to remove any surface contaminants, then apply a suitable welding filler rod compatible with carbon steel.

Is the tube compatible with standard fastening hardware?

Absolutely. The 1-3/4″ square profile matches common bolt and nut sizes, allowing you to use standard washers, brackets, and clamps. For added security in high‑stress applications, consider using high‑strength bolts and lock washers.

What is the corrosion resistance of this steel tube?

While the tube is made from carbon steel, it is coated with a protective finish that helps resist rust during storage and transport. For long‑term outdoor use, we recommend applying a rust‑inhibiting paint or powder coating to further protect the material from the elements.
