Overview
Metalco Extrusions Global LLP is a leading 3003 Aluminium Square Bars Manufacturer, offering precision-extruded square bars made from marine-grade and corrosion-resistant 3003 aluminium alloy. Our 3003 Aluminium Square Bars are engineered to deliver excellent workability, moderate strength, and long-term durability — making them ideal for a wide range of industrial and architectural applications.
Why Choose 3003 Aluminium Square Bars?
3003 aluminium is part of the 3xxx series, an Al-Mn alloy known for its excellent corrosion resistance, good formability, and weldability.Â
- It is a non-heat-treatable alloy, which means that its strength is enhanced primarily by cold working rather than by thermal processes.
- The typical chemical composition includes about 1.0–1.5% manganese, up to 0.2% copper, and trace amounts of iron and silicon, with the remainder being aluminium.
- With a density of ~2.73 g/cm³, 3003 alloy provides a lightweight but durable solution.Â
Key benefits of 3003 Aluminium Square Bars include:
- Excellent corrosion resistance, especially in atmospheric and marine environments.
- Good formability, enabling bending, welding, deep drawing, and machining with ease.
- Moderate strength, stronger than very pure aluminium (e.g., 1100 series) but not as strong as some higher-strength alloys.
- Weldability — the alloy can be welded easily using common welding techniques.
- Cost-effective — due to its balance of mechanical performance and ease of processing, 3003 is widely used and readily available.
Our Capabilities — As a Leading 3003 Aluminium Square Bars Manufacturer
At Metalco Global, we leverage advanced extrusion and finishing processes to produce Aluminium 3003 Square Bars in a variety of sizes, tempers, and tolerances to meet our customers’ needs. Our manufacturing capabilities include:
- Custom Cross-Sections: We can extrude square bars in a broad range of dimensions (e.g., from small-profile precision bars to larger structural sections).
- Tempers & Finishes: We supply bars in common tempers such as O (annealed), H12, H14, H18, etc., depending on the required strength and formability.
- Quality Assurance: All our square bars undergo rigorous quality checks, including dimensional accuracy, surface finish, and mechanical testing, to ensure conformity with standards.
- Bulk Production & Export: We are one of the trusted Aluminium 3003 Square Bars Suppliers globally. Our production capacity, inventory management, and export logistics allow us to serve large-scale industrial users and fabricators.
Applications of 3003 Aluminium Square Bars
Because of their versatile properties, 3003 Aluminium Square Bars are used across a variety of industries:
- Construction & Architecture: For architectural trims, framing, and cladding where corrosion resistance and aesthetic appeal matter.
- Chemical Equipment: Suitable for fabricating tanks, vessels, and structural supports in chemical plants, as 3003 resists many corrosive environments.
- Food & Beverage Industry: Safe for use in food storage systems, storage containers, and structural components due to its non-toxic and non-reactive nature.
- Cold Storage & Refrigeration: Widely used in cold room structures and insulation framing because of its good thermal properties and lightweight strength.
- Transportation / Automotive: Used in fuel tanks, panels, and body parts where weight-saving is important.
- General Fabrication: Ideal for machined parts, welded assemblies, and any application where good formability and moderate strength are required.
