Aluminium flat bars/strips are long and narrow pieces of aluminium with a rectangular cross-section. They have consistent thickness from top to bottom and are available in various sizes. They are also produced in both metric and imperial sizes. Flat bars/strips can be made from pure aluminium or different aluminium alloys, depending on the specific needs of an application.
Lightweight
Aluminium has a density of 2.7 g/cm³, which is approximately one-third of the density of steel. This makes Aluminium flat rods ideal for applications where weight is a concern, such as in the automotive and aerospace industries.
High Strength-to-weight ratio
Despite its lightweight nature, aluminium has a high strength-to-weight ratio, which means it can bear heavy loads without compromising its structural integrity. This property makes it suitable for use in structures such as bridges and buildings.
Corrosion Resistance
Unlike other metals, aluminium has a natural oxide layer that forms on its surface when exposed to air. This layer acts as a protective barrier against corrosion, making it ideal for outdoor applications and in harsh environments.
Conductivity
Aluminium is an excellent conductor of heat and electricity, making it suitable for use in electrical components and heat exchangers.
Malleability and Ductility
Aluminium is highly malleable and ductile, meaning it can be easily formed into various shapes without breaking or cracking. This makes it a versatile material that can be used in a variety of applications.

Extruded Aluminum Flat Bar vs. Cold-Finished Aluminum Flat Bar: How to Choose?
Extruded Aluminum Flat Bar: Formed by pushing heated aluminum billets through a shaped die.
Pros: Highly cost-effective, ideal for structural framing, busbars, and architectural use where standard architectural tolerances are acceptable.
Typical Finishes: Mill finish (slightly lined surface).
Cold-Finished / Cold-Drawn Aluminum Flat Bar: After extrusion, the bar is pulled through a die at room temperature.
Pros: Yields highly precise dimensional tolerances (h9-h11), superior straightness, and a much smoother surface finish.
Best for: High-speed CNC machining, automated feeding systems, and tight-tolerance mechanical parts.
Working with Aluminum Flat Rod
Cutting
Aluminium flat rod can be easily cut using a hacksaw or power saw with a carbide-tipped blade. It is important to use the appropriate cutting tools and techniques to avoid damaging the material.
Bending
The Aluminium flat rod can be bent using a bending machine or by heating the material and shaping it to the desired angle. Care must be taken during the bending process to avoid causing cracks or fractures in the metal.
Welding
Aluminium flat rod can be welded using various methods such as TIG, MIG, and arc welding. It is important to clean the surface of the bar properly before welding to ensure a strong and clean weld.
Drilling
Aluminium flat rod can be drilled using standard metal drill bits. It is important to use a lubricant during drilling to prevent the bit from overheating and causing damage to the material.
Finishing
Depending on the application, Aluminium flat rod may require finishing such as anodizing or powder coating for added durability and corrosion resistance.
Safety
As with any metalworking process, it is important to take safety precautions when working with Aluminium flat rod. This includes wearing appropriate protective gear such as gloves, goggles, and a dust mask to avoid inhaling aluminium particles.
Your Reliable Aluminum Sourcing Partner in China
Delivering Quality, Traceability, and Value to Global Manufacturers
Direct Factory Capacity & Competitive Pricing
Skip the middlemen and eliminate hidden markups. As an integrated aluminum manufacturer, GNEE operates state-of-the-art extrusion presses (up to 3,500 tons) and precision cold-drawing lines. Whether your project requires a 3-ton trial order or a 300-ton continuous monthly supply, our robust production capacity ensures factory-direct pricing, stable lead times (typically 15-20 days), and maximum cost-efficiency for your procurement.
Export Expertise for Middle East & SEA
Over 18 years of seamless global logistics. We deeply understand the market requirements in the UAE, Saudi Arabia, Qatar, Vietnam, and Malaysia. Our dedicated export team handles everything from securing competitive ocean freight rates (FOB/CIF) to providing complete, error-free customs documentation (including Certificate of Origin, SASO, and commercial invoices), ensuring a smooth experience.
Seaworthy Packaging
We know that high humidity and temperature fluctuations during sea transit can cause aluminum oxidation. We never cut corners on packaging. Every batch of aluminum round rods undergoes our strict 4-step export packing standard:
- Step 1 (Separation): Rods are tightly bundled or separated with pearl cotton (EPE) to prevent friction scratches during transit.
- Step 2 (Waterproofing): Tightly wrapped in heavy-duty waterproof kraft paper and thick plastic stretch film.
- Step 3 (Moisture Control): Industrial desiccant bags are strategically placed inside the wrapping to absorb container moisture.
- Step 4 (Palletizing): Securely strapped with steel/PET bands onto ISPM-15-compliant fumigated wooden pallets, ensuring safe forklift handling.
Value-Added Services of GNEE
We do more than just supply raw aluminum. To help you reduce secondary processing costs, minimize material waste, and speed up your production, GNEE offers a full suite of in-house processing and testing services.
1. Precision Cutting & Semi-Machining
- Precision Cut-to-Length: Using high-speed CNC circular saws, we cut rods to your exact length. Standard tolerance is ±1.0 mm, with ultra-precision cutting available up to ±0.1 mm.
- Chamfering & Deburring: We provide chamfered ends (e.g., 30°, 45°) and smooth deburring. This ensures the rods are ready to be fed directly into your CNC lathes or automatic feeding machines without jamming.
- Custom CNC Machining: Need more than just a bar? We offer deep processing, including drilling, milling, threading, and turning, to deliver semi-finished components based on your CAD drawings.
2. Surface Treatments
- Anodizing: Highly recommended for Middle East and coastal projects. We offer clear, color, and Hard Anodizing (Type III) to dramatically increase wear and corrosion resistance against extreme sun, sand, and salty air.
- Sandblasting / Bead Blasting: Provides a uniform matte finish, hiding extrusion lines and preparing the surface for excellent coating adhesion.
- Polishing & Brushing: Mechanical polishing (up to mirror finish) and directional brushing for architectural and aesthetic applications.
- Powder Coating: Available in full RAL colors with UV-resistant coatings for outdoor structural uses.
3. Strict Quality Control & Testing
- 100% Ultrasonic Testing (UT): Internal cracks or voids can destroy your project. We conduct rigorous UT on aerospace and marine-grade rods (like 7075, 2024, and 5083) to guarantee flawless internal structures (compliant with AMS-STD-2154).
- OES Chemical Analysis: Using Optical Emission Spectrometry (OES) to guarantee the exact chemical composition of every alloy batch before pouring.
- Mechanical Property Testing: In-house testing for Tensile Strength, Yield Strength, and Elongation to ensure the tempers (e.g., T6, T651) meet ASTM/EN standards.
- Hardness Testing: Routine Brinell, Rockwell, or Webster hardness testing provided on all heat-treated bars.
4. Custom Packaging & Identification
- Color-Coding & Laser Marking: To prevent material mix-ups in your warehouse, we can paint rod ends with specific colors (e.g., Red for 6061 and blue for 7075) and laser-print heat numbers/alloy grades directly on the bars.
- VCI Anti-Corrosion Packaging: Essential for Southeast Asian shipping. We use Vapor Corrosion Inhibitor (VCI) paper and waterproof shrink wrap, securely strapped on fumigated wooden pallets, ensuring 0% white rust upon arrival.
