Benefits of Using Aluminum Rectangular Tubing
High Strength-to-Weight Ratio: Provides robust structural support with significantly less weight than steel, perfect for weight-sensitive designs and reducing shipping costs.
Superior Durability: Naturally resistant to corrosion and can be further enhanced with anodizing or powder coating, ensuring long service life even in harsh environments.
Design Flexibility: The rectangular shape provides directional strength and is easy to cut, weld, and join, allowing for versatile and efficient designs.
Cost-Effective: Aluminum is a cost-efficient material over its lifecycle due to its durability, low maintenance, and high recyclability.
Our versatile aluminum rectangular tubes are essential components in numerous industries:
Structural & Construction: Building frames, gate frames, support beams, roof trusses, handrails.
Machinery & Automation: Machine guarding, equipment frames, conveyor systems, robotics.
Automotive & Transport: Truck beds, trailers, chassis components, racks.
Architectural: Window and door frames, mullions, decorative elements.
Solar & Renewable Energy: Mounting structures and support frames for solar panels.

Frequently Asked Questions (FAQ)
What's the main difference between 6061 and 6063 rectangular tubing?
6061-T6 is a structural alloy with higher strength, ideal for load-bearing applications like machine frames and support beams. 6063-T5 is an architectural alloy with a better surface finish and is more suitable for applications like window frames, trim, and railings where aesthetics are important.
Can you manufacture a rectangular tube with different wall thicknesses on the height and width?
This would be a custom profile. While standard rectangular tubes have uniform wall thickness, we absolutely have the capability to extrude custom profiles to your exact design. Please send us your drawing for a quote.
What is the difference between an aluminum tube and an aluminum pipe?
Generally speaking, a “tube” is defined by its exact outside dimensions (e.g. 50 mm x 100 mm) and is used for structural and mechanical applications. A “pipe” is defined by its nominal inside diameter and is used to transport fluids or gases.
What is your Minimum Order Quantity (MOQ)?
For our in-stock items, we can accommodate smaller orders. For custom extrusions, the typical MOQ is 500kg per size, as this is the most economical production run. Please contact us to discuss your specific needs.
