Start with the required width and thickness, then check the edge shape, length, and manufacturing requirements. The correct profile depends on its intended use, including any machining, fastening, or finishing operations.
For load-bearing or electrical applications, do not select a flat bar by dimensions alone. Include the relevant performance requirements so the material specification can be reviewed.
Aluminium material with a solid structure that provides high resistance to pressure and heavy loads, making it ideal for industrial and construction requirements.
We provide a 30-day product quality guarantee to ensure you receive material that meets the highest standards and is free from production defects.
Available in anodizing, powder coating, and mill finish options, offering durability and a clean appearance for various applications.
Aluminium offers excellent formability, allowing it to be easily shaped and fabricated into various designs without compromising strength ideal for custom and complex applications.
Bring design to us and we can turn your ideas into precise, high-quality aluminium solutions. Custom sizes, specification and finishing tailored to your project needs.
We primarily use 6061 for structural applications needing high strength, and 6063 for architectural uses requiring an excellent finish.
Yes, specific alloys like 6101 or high-purity 6063 are excellent for electrical busbars due to their high conductivity.
Yes, depending on the alloy and temper (e.g., T4 vs T6), our flat bars can be formed or bent. Please consult our team for bending specifications.
We offer a wide range of standard thicknesses from 2mm up to heavy-duty solid blocks. Custom dimensions are available upon request.
Yes, we can supply full extrusion lengths or provide precision cut-to-length services based on your project needs.
Absolutely. We offer clear, black, and custom color anodizing to enhance surface hardness and aesthetics.
An aluminum flat bar is a solid rectangular section, wider than it is thick, and that plain shape is why fabricators use it so often. It works as a base, brace, edge cap, bracket, or spacer with none of the setup an angle or hollow section needs. As an aluminum flat bar supplier extruding in Indonesia, we run the common sizes in 6061 and 6063, from thin strips to heavy stock.
A flat bar is defined by two numbers, width and thickness, and by its edge. Square-edge bars give crisp corners for clean joints and tight stacking, while rounded-edge bars carry a corner radius that resists chipping and suits handrails and trims. Both are solid through, so you can drill, punch, or tap anywhere along the length. An aluminum flat bar supplier stocks both, so the edge comes down to the job.
The manufacturing route matters more than most buyers expect. Extruded flat bar, pressed hot through a die, covers the bulk of architectural and structural work. Cold-finished or rolled bar, drawn to size, holds tighter tolerances with a better surface for precision fitting. Most work does not need that, so as an aluminum flat bar supplier we extrude the standard sizes and flag when a job genuinely needs the cold-finished route.
How you install the bar changes its stiffness more than its grade does. Laid flat, a bar resists little bending; stood on edge, it is many times stiffer. Decide the loaded direction first, because a thick bar in the wrong orientation still sags. Tell your aluminum flat bar supplier the span and the load, and the section is matched to the duty.
Weight follows the cross-section: multiply width by thickness in millimetres by 0.0027 for the mass in kilograms per metre. A sample of our range shows the spread.
Section | Size (W x T) | Weight (kg/m) |
10031 | 25 x 3 mm | 0.203 |
10040 | 50 x 5 mm | 0.678 |
10065 | 60 x 6 mm | 0.976 |
10251 | 115 x 10 mm | 3.117 |
Figures follow the Exalum flat bar catalogue; use the formula for any size not listed.
Knowing weight early helps budget freight, and any aluminum flat bar supplier should quote it per metre.
The grade decides how a bar machines, bends, welds, and finishes. As an aluminum flat bar supplier we extrude 6061-T6 for structural and machined parts, 6063-T5 for architectural work that will be anodized, and high-purity 6063 or 6101 for electrical bar where conductivity counts. For parts that will be heavily machined, the harder 6061-T6 holds its shape and finish better than a softer temper. The wider market also uses 5052-H32 for marine and tight bends, and 2024 or 7075 for aerospace; those are rolled alloys outside an extruder's range, so specify them only when the job genuinely calls for it.
A few habits prevent the common flat-bar mistakes. Drill on the centreline and deburr both faces so parts seat flat. Respect a bending radius, since 6061-T6 is strong but not very formable and tight bends belong to softer tempers. Treat welding with care: the heat-affected zone around a weld on 6061-T6 loses real strength, so keep that softened band away from the highest stress. A good aluminum flat bar supplier flags these before the shop floor.
The same stock serves very different trades. Common duties include base plates and mounting strips, brackets and gussets, frame and bracing members, edge caps and trims, ladder and railing parts, and conductive bar for switchgear. Because it is solid and quick to cut, one order often covers several at once, which is why an aluminum flat bar supplier ships it by the bundle.
A short checklist keeps a flat bar order clean and on time. Specify the section or the exact width and thickness, the edge type, the alloy and temper, the finish, and the cut length with its tolerance. Add the quantity and the delivery date, and note where a surface will show so it is protected in transit. Sending these once lets your aluminum flat bar supplier quote right the first time.
Flat bar is a cutting-service product, so most parts leave as short pieces, not full lengths. Send a cutting list or drawing, and the bars arrive faced to length, deburred, and ready to fit, in mill, anodized, or powder-coated finish. Non-standard widths come from the die library, custom sections from a new die. As your aluminum flat bar supplier, we reply with alloy, temper, tolerance, price, and lead time from our factory in Indonesia; for solid round stock, see our Round Bar page.
