Products features
Superior Material Performance:
Crafted from high-grade 6061/6063/6082 aluminum alloys, featuring high tensile strength (≥270MPa for T6 temper) and excellent thermal conductivity, suitable for heat-dissipating equipment shells.
Lightweight & High Load-Bearing:
30% lighter than steel tubes with comparable load capacity, reducing equipment overall weight while ensuring structural stability for long-term use.
Seamless Extrusion Craftsmanship:
One-piece extrusion forming eliminates welding seams, avoiding stress concentration and enhancing resistance to impact and vibration-critical for heavy-duty machinery enclosures.
Design Flexibility:
Supports integration of built-in channels, mounting slots, or reinforcement ribs during extrusion, reducing post-processing steps and improving assembly efficiency for equipment shells.
Products application
Our extruded aluminum equipment shell square tubes are widely applied in scenarios requiring durability, precision, and corrosion resistance:
- Industrial Automation: Enclosures for PLC control cabinets, robotic arms, and conveyor system frames-withstand frequent mechanical movement and factory dust.
- Electronics & Electrical: Housings for power supplies, server racks, and frequency converters-excellent thermal conductivity protects internal components from overheating.
- Medical Devices: Shells for diagnostic equipment (e.g., ultrasound machines) and surgical tools-non-toxic, easy-to-sterilize surface treatments meet medical hygiene standards.
- Renewable Energy: Frames for solar inverters, wind turbine control boxes-resist outdoor moisture, UV rays, and temperature fluctuations (tested for -40℃ to 80℃ operation).
- Transportation: Cabinets for on-board equipment in electric vehicles, trains, and ships-lightweight design reduces energy consumption while ensuring impact resistance.

Frequently Asked Questions (FAQ)
What information do I need to provide for custom extruded aluminum equipment shell square tubes?
You only need to share 3 key details: (1) Required dimensions (length/width/wall thickness) or 2D/3D design drawings; (2) Application scenario (e.g., medical equipment, solar inverter) to confirm alloy/temper; (3) Surface finish and CNC processing needs. Our engineering team will then provide a tailored solution within 24 hours.
How do you ensure the products meet my local industry standards?
We hold global certifications (CE, TUV, SGS, RoHS, KS) and comply with EN 755-9, ASTM B221, and other regional standards. Before shipment, we provide material certificates and inspection reports. For special standards (e.g., medical ISO 13485), our in-house lab can conduct additional tests to meet your requirements.
What if the received products have quality issues?
We offer a 100% quality guarantee: If defects are caused by our production (e.g., dimensional deviation, coating peeling), we will either re-produce and ship replacements for free or provide a full refund-whichever you prefer. Our dedicated account manager will resolve the issue within 48 hours of receiving your feedback.
Can you handle small-batch orders for prototype development?
Absolutely. We support small-batch orders starting from 100kg (lower than industry average MOQ of 500kg) for prototype or trial production. With 25 extrusion lines, we can adjust production capacity flexibly, ensuring fast turnaround (10-15 days) even for small orders.
