Do You Know What Specifications 4040 Extruded Aluminum Has
Updated: 11 Mar 2026
The 4040 extruded aluminum we often refer to is an aluminum profile with a cross-section of 40*40 mm. Its load-bearing capacity depends on the frame design, span, and connection method, but it can generally meet the requirements of most industrial frame structures. It is frequently used for custom workbenches, equipment guards, partitions, shelves, trolleys, etc. Because of its wide range of applications, it comes in many specifications.
This profile weighs 1.45 kg/m and is commonly used in the manufacture of workshop workbenches, small material racks, and mobile trolleys. The 4040 lightweight profile features a 2mm-thick diagonal rib, a 6.8mm center hole, and slot 8 series.
4040 Standard Aluminum
This profile weighs 1.85 kg/m and is commonly used in the manufacture of assembly line workbenches, conveyor lines, and assembly lines. The standard 4040 profile has a 2.5mm thick diagonal rib, a 6.8mm central hole, and slot 8 series.
4040 Heavy-Duty Aluminum
This profile weighs 2.2kg per meter and is commonly used in equipment supports, equipment protective covers, electrical workbenches, and laboratory workbenches. This profile has a higher load-bearing capacity than the previous two types, making it suitable for frame assemblies requiring increased stress and strength.
4040 Right-Angle Aluminum
The 4040 right-angle profile comes in two specifications: light-duty and heavy-duty. Its corners are right angles, designed with two 90-degree outer edges, making it suitable for frame corners and panel installations.
4040 Rounded Profile: Commonly used for corner columns in frames, it is smoother and provides a smooth edge design, improving safety and aesthetics in frame structures. Its wall thickness is 2mm and slot 8 series.
4040 Slot 10 Profile Aluminum
Within the 4040 series, there is a slot 10 profile aluminum, namely 4040F. The main difference lies in the slot width, which requires slot 10 compatible fasteners and accessories. For specific accessory selection, please consult the Shenghai Aluminum engineering team.
4040 Double Slot Aluminum Profile
This aluminum profile also differs from other specifications; it is double-slotted and primarily used for door rails, making it a superior choice for sliding door rails. Another difference is that this profile belongs to the slot 6 series, meaning many accessories may not be compatible.
These are the commonly used specifications for 4040 slot aluminum. For more information on 4040 slot extrusion, please feel free to contact us.
