Rectangular steel tubing, also known as structural rectangular tubing, is a type of metal profile with a rectangular hollow cross section which is used in numerous applications, including structural support and fabrication.
This profile is popularly referred to as “box section” or “rectangular tubing” and can be made from either hot rolled or cold rolled steel, depending on the application and desired finish. Rectangular steel tubing offers strength, durability and versatility in a wide range of applications such as vehicle frames, fire escapes, stairs, railings, window frames, clothing racks and much more.
The versatility of rectangular steel tubing makes it a great choice for any industry or project.

What are the different types of steel tubing?
Steel tubing is a versatile material widely used for a variety of applications and products. Steel tubing is composed of a variety of alloyed steels, each type offering unique physical and chemical properties.
The different types of steel tubing available include:
• Carbon Steel Tubing – This type of tubing is made from low-carbon steel, making it strong and reliable. It is often used in oil and gas piping, structural tubing, domestic hot water heating systems, pipelines, fencing, and more.
• Seamless Steel Tubing – This type of tubing is produced without a seam, creating a solid steel cylinder with superior strength. It is often used for items like exhaust system components, gas lines, and pressure vessels.
• Stainless Steel Tubing – This type of tubing is made from an alloy of iron, chromium, and nickel. It is resistant to corrosion and is often used in food-grade applications, heat exchangers, and fuel lines.
• Galvanized Steel Tubing – Galvanizing is the process of coating steel tubing with zinc, creating a corrosion-resistant seal. This is often used in exterior applications like fenceposts and railings, as well as automotive components.
• Copper Tubing – This type of tubing is made from a combination of copper and zinc, producing a corrosion-resistant, malleable material. It is often used as wiring, plumbing, and waterworks.
• Aluminum Tubing – This lightweight material is made from a blend of aluminum and other elements, like magnesium and manganese. This type of tubing is used in automotive and aircraft manufacturing, as well as in electrical transmission.
What is the difference between N 80 and L 80 tubing?
N 80 and L 80 are both types of tubing used in the oil and gas industry. While both types of tubing have some similar characteristics, they have some notable differences.
N 80 tubing is a seamless, carbon steel pipe made to API (American Petroleum Institute) specification 5CT. It is typically used in oil and gas wells where the life expectancy of the tubing is roughly 15-20 years.
The N 80 grade has a higher yield and tensile strength, as well as higher corrosion resistance than L 80 tubing.
L 80 tubing is also a seamless, carbon steel pipe made to API 5CT. The difference with L80 is that it is less expensive than N 80 and is therefore typically used in land-based production wells. The life expectancy on the L 80 grade of tubing is typically shorter than N 80 grade tubing, around 7-10 years.
The L 80 grade offers lower yield, tensile strength, and corrosion resistance than the N 80 grade.
Overall, N 80 tubing is the more expensive and higher quality of the two, and is therefore typically used in offshore wells, whereas L 80 tubing is used in more cost-sensitive, land-based wells.
How many types of tubing are there?
Some common types of tubing include copper, stainless steel, aluminum, polyethylene, PVC, CPVC, and PEX. Copper is a soft metal that is corrosion-resistant and highly conductive, making it well-suited for plumbing and electrical applications.
Stainless steel is a strong, corrosion-resistant alloy that is used in many industries, including food processing, medical, and automotive. Aluminum is lightweight and has good thermal and electrical conductivity.
Polyethylene is the most common type of plastic tubing that is used in a variety of applications, including plumbing and electrical wiring. PVC (polyvinyl chloride) is a common type of plastic tubing that is strong, lightweight, and resistant to corrosion and environmental factors.
CPVC (chlorinated polyvinyl chloride) is similar to PVC, but has better heat resistance and chemical resistance. PEX (cross-linked polyethylene) is flexible and lightweight, and is commonly used in plumbing, heating, and cooling applications.
How strong is 2×3 steel tubing?
2×3 steel tubing is a strong material and is commonly used for industrial and construction applications. Its strength and durability make it a great choice for building structures and supports. Specifically, 2×3 steel tubing typically has a minimum yield strength of 36,000 PSI (pounds per square inch) and a minimum tensile strength of 58,000 PSI.
The steel tubing also has good weldability properties and is corrosion resistant, making it ideal for outdoor applications. Additionally, 2×3 steel tubing meets a variety of ASTM standards, as well as local building codes.
How much weight can steel tubing hold?
The amount of weight steel tubing can hold depends on several factors, including its type, shape, size, and thickness. Generally speaking, steel tubing can hold a considerable amount of weight, as long as it is adequately engineered and manufacturer-tested to ensure that the tubing meets the applicable code requirements.
The carrying capacity of steel tubing also depends on its application, how it is being used, and the intended loading strength capacity or design criteria. Structural grade steel tubing can typically withstand a maximum capacity of between 50,000 and 75,000 lbs, while lighter-duty tubing is typically good for up to 25,000 lbs.
Steel tubing is also more than capable of bearing the load of cars, trucks, and other heavier equipment when it is specifically designed to resist shear and torsion forces caused by external loading—which is why it is so often used for vehicle support beams, columns, and frames.
Is steel tubing stronger than steel pipe?
Overall, steel tubing is indeed stronger than steel pipe, typically by a factor of about six times. This is because steel tubing features a much thinner wall thickness than steel pipe – typically between 0.
049 inches and 0. 120 inches compared to 0. 109 inches to 0. 314 inches for steel pipe – which makes it more rigid and resistant to pressure. On top of that, steel tubing also typically features higher tensile strength and yield strengths than steel pipe, which makes it even more durable, particularly in volatile and high-pressure applications.
Ultimately, steel tubing is the superior choice when it comes to strength and durability when compared to steel pipe.
Are steel tubes strong?
Yes, steel tubes are strong and highly durable. This is due to the strong nature of steel which makes it a great choice for both industrial and commercial applications. Steel itself is an alloy of iron and other elements and is known for its strength and ability to withstand corrosion.
Steel tubes in particular have a higher tensile strength compared to other types of steel, making them even more resilient. They are resistant to fatigue, vibration, impacts, and both extreme temperatures and pressures.
Steel tubes are also relatively light and easy to transport and install, making them a popular choice for structural and fabrication projects. In addition to this, they are very affordable and widely available.
