Aluminum square tubing is an extruded hollow structural segment that features square inner and outer corners without weld seams. Aluminum square tubes are priced for their high strength-to-weight ratio, versatility, durability, and corrosion resistance.
They are ideal for fabrications where strength is required without adding too much weight. Aluminum square tubes are widely used in construction and architectural applications. Herein is a brief overview of aluminum square tubing.
How are Square Aluminum Tubes Manufactured?
Aluminum square tubes are produced by extruders using the aluminum extrusion process. This fabrication technique entails forcing a preheated solid but malleable aluminum alloy (billet) through an extrusion die. Different alloys, each with a unique set of properties, are used to produce square aluminum tubes. The most common types are aluminum 6061, 6063, and 2024.
The extrusion die features a specific cross-sectional profile. In the case of aluminum square tubes, the die profile is square-shaped with a square opening. Manufacturers use a machine referred to as an extruder for this process. The aluminum alloy stock comes out the other end as a fully formed square tube.
Manufacturers then saw off, cool, stretch, and cut the tube to predetermined lengths. Aluminum square tubes are available in lengths ranging from 2 feet to 24 feet. You may also order custom-cut lengths for specific use cases. Once the extrusion process is complete, the square aluminum tubes are heat-treated and finished before they can undergo fabrication processes.
Beneficial Properties of Aluminum Square Tubing
- Flexibility – due to the combination of aluminum’s characteristics, square tubing made from the material is highly versatile. The tubes can be easily fabricated using various metal working processes such as cutting and welding to cater to specific project requirements.
- Lightweight – aluminum square tubes are one-third the weight of steel tubing. This makes the construction material easier to transport and handle on sight. It also makes it a great option where low weight and strength are primary concerns.
- Strength – aluminum is a third the weight of steel while being just as strong. Developers can use square aluminum tubes in construction to meet strength performance requirements while reducing costs on foundations.
- Durability – as a construction material, aluminum square tubes are resistant to corrosion, weather elements (moisture, high winds, extreme cold, and heat), and UV rays. This makes them ideal for outside constructions as they guarantee optimal performance against the elements for a long time.
Applications of Aluminum Square Tubes
Square aluminum tubes have a wide range of residential, commercial, and industrial applications. These structural components are mostly used in construction projects and machine parts. Aluminum square tubing is an easily fabricated construction material suitable for indoor and outdoor use.
The most common applications in construction include support columns, frameworks, fencing, and gates. Other structural uses include truck bodies and frames, walkways, platforms, steps, floors, cover plates, and trench covers. 6061 aluminum alloy is generally used for structural purposes since strength is especially important.
Architectural applications of square aluminum tubing include interior and exterior décor features, furniture, handrails, and luggage racks. For architectural purposes, square tubes made from aluminum alloy 6063 are preferable. This is because its surface finish is smoother compared to other alloys.
Square aluminum tubes are also used in the marine industry. Commercial, recreational, and military marine vessels use marine-grade aluminum square tubing due to its strength, excellent workability, and corrosion resistance. 6061 aluminum alloy is generally used for marine purposes since it has exceptional strength and enhanced corrosion resistance.
