Product Description

PRODUCT INTRODUCTION

Aluminum Profile Square Tubes Core Advantages 

1. Lightweight and High Strength  

   - Weighs only one-third of steel with exceptional load capacity (e.g., 80×80mm supports 500kg)  

   - Reduces handling effort, ideal for aerial operations  

2. Corrosion Resistance & Maintenance-Free  

   - Natural anti-rust oxide layer withstands 20+ years in humid/acid/alkali environments  

   - 40% cheaper than stainless steel** with zero rust-prevention treatments  

3. Flexible Processing  

   - Effortless cutting, bending, and drilling  

   - Bolt/rivet assembly – no welding needed  

4. Eco-Friendly Aesthetics  

   - Customizable surfaces: colors (silver/champagne/black) or wood-grain effects  

   - 100% recyclable material, energy-efficient  

Aluminum Square Tubes  are engineered to deliver an outstanding high strength-to-weight ratio, boasting a density of just 2.7g/cm³ and a tensile strength of at least 215MPa with the 6063-T6 alloy. The innovative hollow structure enhances bending stiffness by an impressive 40% compared to traditional solid profiles. Experience superior weatherability with anodized surfaces that can withstand over 1000 hours of rigorous salt spray testing, and powder-coated finishes that excel in QUV aging tests for more than 2000 hours. Benefit from remarkable manufacturing efficiencies with a cutting speed of 120 meters per hour and assembly that's 60% faster using corner brackets instead of traditional welding, alongside CNC machining precision of ±0.05mm. The lifecycle advantages include a maintenance-free service life exceeding 30 years, an exceptional extrusion yield of more than 92%, and complete recyclability with a residual value surpassing 60%. The thermal conductivity of 237W/(m·K) makes these tubes perfect for heat dissipation applications. Our Aluminum Square Tubes are the ideal choice for a multitude of applications, including building curtain walls where they achieve a 50% weight reduction, automation frames capable of supporting a 5-ton load capacity, solar mounts with a robust 25-year UV resistance, and rail transit solutions that meet the EN 45545-2 flame retardancy standards, offering comprehensive superiority over steel tubes.

OUR CERTIFICATE

Q1. Material properties and tolerance control

Customer issue: Are the alloy grades, mechanical properties (tensile strength, elongation) and dimensional tolerances of the aluminum profiles in line with international standards (such as ASTM, EN)?

A:We use mainstream alloys such as 6061-T6 and 6063-T5, which comply with the ASTM B221/EN 755 standards. The tensile strength of the conventional profiles is 2 240 MPa, and the dimensional tolerances strictly follow the ISO 2768 medium precision standard. We can also provide third-party test reports (such as SGS).

Q2. Surface Treatment Process

Customer Question: How are the film thickness, corrosion resistance and color difference controlled for anodizing and powder coating?

The thickness of the anodic oxide film is 12-25 um (in line with QUALIcoAT Class Il), and the salt spray test lasts for over 1000 hours; the powder coating complies with the AAMA 2604 standard, with a color difference ΔE of s 1.5. Customization of RAL/Pantone color codes is supported.

Q3. Environmental Compliance

Customer Question: Does it comply with environmental regulations such as RoHS/REACH?

The product is completely free of harmful substances such as cadmium and lead, and the packaging materials are recyclable.

Q4. Price and MOQ Flexibility

Customer Question: Are the minimum order quantity (MOQ) and unit price competitive?

Reply: Standard profiles have a minimum order quantity of 1 ton and support small batch customization.

5. Customized Development Support

Customer Question: Can non-standard cross-sections (such as vehicle structural profiles, radiator irregular profiles) be produced?

It is equipped with an 800T-3500T extrusion machine group, capable of producing complex profiles with an outer circular section diameter of sp380mm (such as the frame of high-speed rail carriages and car luggage racks). It offers a one-stop service from mold design to extrusion and finishing, with a sample production cycle of 15 days.

6. Delivery and Logistics Assurance

Customer Question: How will the delivery schedule and international logistics be arranged?

The delivery period for standard products is 25 days, and for customized products it is 35 days. The logistics can be dispatched according to the customer's specified logistics. Thank you.
