Applications
Where t-slot profiles are used
Choose the series for the load and span, then match fasteners to the slot width. Multiples such as 40 × 80 and 80 × 80 add stiffness while keeping the same fastener system.
- Machine frames and bases
- Workstations and benches
- Safety guarding
- Conveyor structures
- Jigs, fixtures and 3D printers
Questions
How much does a 4040 aluminum profile weigh?
A standard 40 × 40 B-type profile with an 8 mm slot typically weighs about 1.5–1.7 kg per metre, depending on its internal design. Each profile page lists the calculated weight for that section.
What does 4040 mean in aluminum profiles?
It is the cross-section size in millimetres: 40 × 40 mm. Likewise 2020 is 20 × 20 mm and 4080 is 40 × 80 mm.
