An aluminum square tube / rectangular profile tube is a highly demanded type of rolled non-ferrous metal product that perfectly combines lightweight properties, high bending strength, and excellent corrosion resistance. Due to its hollow cross-section and four structural ribs of rigidity, the aluminum profile tube is an indispensable material in construction, furniture manufacturing, and architectural design.

Popular Sizes of Square Aluminum Profiles

• Square Aluminum Tube 10×10 mm: A compact profile designed for manufacturing decorative accents, commercial advertising structures, and lightweight frames.
• Square Aluminum Tube 20×20 mm: A versatile, multi-purpose size widely utilized for building office partitions, retail display equipment, and residential framing assemblies.
• Square Aluminum Tube 30×30 mm: A durable profile heavily applied across the furniture industry and for assembling heavy-duty commercial shelving systems.
• Square Aluminum Tube 40×40 mm: An enhanced, reinforced option engineered for loaded metal structures, small architectural forms, and exterior facade cladding elements.
• Square Aluminum Tube 50×50 mm: Utilized in the construction of lightweight gazebos, pavilions, commercial kiosks, and architectural window or door frames.
• Aluminum Profile 60×60 mm and 80×80 mm: Heavy-duty configurations used to create strong, highly stable upright supports, fencing structures, and structural building facade elements.
• Aluminum Profile 100×100 mm, 120×120 mm, and above: High-gauge, heavy aluminum profiles engineered for industrial machinery beds, massive outdoor advertising billboards, and critical, high-load building structures.

Core Alloy Grades and Specifications

• AD31T1 (European Equivalent: EN AW 6063) — “Avial”: The absolute most popular alloy grade for square tubes. Approximately 90% of all profile tubes on the Ukrainian metal market are manufactured from this specific material.
• 6061 (Equivalent to AD33): A structural alloy featuring a higher content of magnesium and silicon than AD31, offering enhanced mechanical strength.
• D16T (European Equivalent: 2024) — “Duralumin”: An ultra-high-strength structural alloy precisely engineered with copper additions.
• AD0, AD1 (Technical Aluminum): Commercially pure aluminum without alloying elements, offering maximum ductility and corrosion resistance.

The wall thickness of duralumin and structural square tubes ranges from 1 mm to 5 mm and thicker. The most high-demand thickness metrics are:

1.0 mm and 1.5 mm: Typical thickness metrics for thin-walled profiles. Primarily used for lightweight decorative works, furniture manufacturing, advertising display stands, and structural assemblies that do not bear significant mechanical loads.

2.0 mm and 3.0 mm: The “golden mean.” These thickness parameters deliver an excellent balance between structural strength and low weight. Ideally suited for the majority of construction framing, handrails, fencing, and multi-purpose industrial frames.

4.0 mm and 5.0 mm: Utilized for heavy-duty, thick-walled profile tubes engineered to withstand substantial loads, industrial processing demands, upright supporting structural nodes, and mechanical engineering applications.
