As a professional aluminum products manufacturer, we specialize in producing precision square aluminum bars for industrial, structural, and custom fabrication applications. With advanced extrusion technology, strict quality control, and flexible customization services, we supply reliable aluminum materials to customers worldwide at competitive factory-direct prices.
This guide explains everything buyers need to know—from material properties and alloy options to sizing, applications, and how to order directly from the manufacturer.
What Is an Aluminum Square Rod?
A square aluminum bar is a solid metal product with a square cross-section, widely used in construction, machining, equipment manufacturing, and custom fabrication. Compared with round bars or flat profiles, square sections provide better structural stability and easier alignment during assembly.
These products are typically manufactured through aluminum extrusion, followed by cutting, straightening, surface finishing, and optional machining based on project requirements.
Key Properties of Square Aluminum Bars
Square aluminum profiles are valued for their balanced mechanical and physical performance.
Strength and Durability
Depending on the alloy, these bars offer excellent strength while remaining durable in long-term use.
Lightweight and Corrosion Resistance
Aluminum is significantly lighter than steel and naturally resists corrosion, making it suitable for both indoor and outdoor environments.
Machinability and Formability
The material is easy to cut, drill, tap, and CNC machine, which helps reduce processing time and cost.
Thermal and Electrical Conductivity
Aluminum provides good heat dissipation and electrical conductivity for industrial and technical applications.
Aluminum Alloys and Material Options
Selecting the correct alloy ensures optimal performance and cost efficiency.
6061 Alloy
A popular choice for structural parts and machining due to its strength, corrosion resistance, and versatility.
6063 Alloy
Known for smooth surface quality and excellent formability, often used in architectural and decorative projects.
7075 Alloy
A high-strength option for demanding applications such as aerospace and tooling.
How to Choose the Right Material
If strength and machinability are critical, 6061 is often recommended. For appearance-focused uses, 6063 is preferred. Our technical team can assist with material selection.
Sizes, Dimensions, and Tolerances
We provide both standard and customized dimensions to match different project needs.
Common Size Options
Available in metric and imperial measurements, including 10mm, 20mm, 25mm, and 1 inch profiles.
Dimensional Accuracy
Tolerances can be controlled based on alloy, size, and processing requirements.
