Introduction
Aluminum Square Tube (also Aluminum Square Pipe, Square Aluminum Tubing, Aluminum Hollow Section, Extruded Aluminum Square Tube, Structural Aluminum Square Tube, Aluminum Box Tube, Aluminum Square Hollow Tube, Aluminum Alloy Square Pipe, or Lightweight Aluminum Square Tubing) is a versatile hollow section widely used in structural, architectural, and industrial applications. It conforms to ASTM B221, available in two primary alloys:
6061 Aluminum Square Tube (6061-T6) – higher strength, excellent weldability and corrosion resistance, ideal for structural framing and load‑bearing applications.
6063 Aluminum Square Tube (6063-T5) – superior surface finish, good formability, excellent anodizing response, ideal for architectural and decorative uses.
This extruded aluminum square tube offers lightweight structural aluminum tubing, corrosion resistant aluminum square tube, high strength aluminum hollow section, excellent weldability aluminum tubing, durable aluminum structural tube, weather resistant aluminum square pipe, anodized aluminum corrosion resistance, easy fabrication aluminum tubing, high strength to weight ratio aluminum, and high performance aluminum extrusion tube.
Note: Square tubes are typically produced by hot extrusion, providing consistent dimensions and surface quality. Welded square tubes are also available for non‑extruded sizes.
Our 6061-T6 and 6063-T5 square tubes are supplied in mill finish, anodized, polished, and cut‑to‑size forms. We offer custom sizes, thin wall, and large size options.
Key standards: ASTM B221, EN 755, GB/T 6892, Aluminum Hollow Section Specification.

Applications
1. Construction & Structural Framing
Aluminum square tube for construction – building frameworks, scaffolding, guardrail posts, handrails, and support columns. Lightweight structural aluminum tubing reduces installation labor compared to steel.
Aluminum square pipe for structural framing – machine bases, workbench frames, conveyor supports, and platform structures. High strength aluminum hollow section with 6061-T6 offers excellent load‑bearing capacity.
Aluminum square tubing for greenhouse frames – greenhouse structures, shade houses, and plant support systems. Weather resistant aluminum square pipe does not rust and requires minimal maintenance.
2. Furniture & Architectural Applications
Aluminum square tubing for furniture – table legs, chair frames, shelving systems, display racks, and outdoor furniture. Easy fabrication aluminum tubing allows welding, drilling, and finishing. Anodized aluminum square tube provides a decorative, scratch‑resistant surface.
Aluminum square tube for architectural applications – curtain wall mullions, window frames, door frames, balustrades, and interior partitions. 6063 aluminum square tube offers superior surface finish for anodizing in silver, bronze, or gold.
Aluminum hollow section for industrial equipment – conveyor rails, protective guards, workstations, and cleanroom framing.
3. Solar Mounting & Trailer Manufacturing
Aluminum square tubing for solar mounting systems – solar panel racking frames, ground‑mount structures, and rooftop support rails. Corrosion resistant aluminum tube withstands outdoor exposure for 25+ years without painting.
Aluminum square tube for trailer frames – utility trailer frames, boat trailer tongues, and equipment trailer crossmembers. Lightweight aluminum square pipe increases payload capacity and reduces tow vehicle fuel consumption.
Aluminum square pipe for transportation industry – truck body framing, cargo container reinforcement, and bus seat frames.
4. Marine & Other Industrial Applications
Aluminum square tube for marine applications – boat deck framing, dock ladders, sailboat masts (in larger sizes), and marine furniture. Anodized aluminum corrosion resistance prevents saltwater attack.
Aluminum square tube for industrial equipment – robotic arm linkages, pneumatic cylinder supports, and machine guarding structures. Durable aluminum structural tube with good weldability for custom fabrication.
