DESCRIPTION

3″ x 3″ x 3/8″ (.375″) HR Steel Square Tube A500 is a hollow structural section (HSS) manufactured from hot rolled carbon steel and produced to ASTM A500 specifications for structural and fabrication applications. This square tube features 3-inch outside dimensions with a 0.375″ (3/8″) wall thickness, providing increased strength, rigidity, and load-bearing capacity compared to thinner wall tubing. A500 steel tubing is known for its consistency, weldability, and durability in demanding environments.

Applications:
HR Steel Square Tube A500 is commonly used in structural, mechanical, and fabrication applications, including:
• Structural frames and heavy-duty supports
• Columns, posts, and load-bearing structures
• Equipment frames and industrial fabrication
• Trailers, racks, and reinforced assemblies
• Construction and architectural projects
• General welding and metalworking applications

Advantages:
• Heavy wall thickness: 3/8″ wall provides superior strength and durability
• High strength: Ideal for load-bearing and structural applications
• Weldable: Easily cut, welded, and fabricated
• Durable: Performs well in industrial and outdoor environments
• Versatile: Suitable for a wide range of heavy-duty applications

Summary:
The 3″ x 3″ x 3/8″ HR Steel Square Tube A500 is a heavy-duty structural steel solution designed for demanding construction and fabrication projects. Its thick wall, strong square profile, and compliance with ASTM A500 standards make it an excellent choice for load-bearing frameworks, supports, and reinforced assemblies requiring maximum strength and durability.

* Prices subject to change without notice due to the Metals Market fluctuations. | All ‘value length’ and ‘value pack’ item measurements are subject to a “mill tolerance”. | A product may be produced several thousandths of an inch, either over or under the stated thickness, and still be within “mill tolerance”. Since we cut the material specifically for your order, they follow these tolerances: Length: +0.125″ / -0.062” – Please note that during cutting, the blade removes about 1/16″ of material (kerf). This is a normal part of the process and is already considered within the stated tolerances.
