I-type profiles
Best quality at a top price
For over 25 years on the market
Best precision & highest stability
The advantages of compatible construction profiles
Our i modular system for the highest demands.
Compatible construction profiles offer great flexibility and enable seamless integration into existing systems, as you can see in our catalog. They impress with their robustness and durability, making them the ideal choice for a wide range of applications.
One outstanding feature of our aluminum profiles is their versatility. It allows not only for various connection techniques, but also for easy adaptation and expansion of the construction. They can therefore be integrated into the most diverse applications without difficulty, always meeting the highest requirements, and they are compatible with dimensionally identical item profiles.
Aluminum construction profiles, item compatible series for your applications
Choose the one that suits your planned construction
Find your i-type profile
Directly by design, contour or groove form.
i-type by design
Standard, light or Economy. The design determines wall thickness and load capacity at the same groove width.
- Standard
- Light
- Economy
- X
- XMS
i-type by contour
Square, rectangular, round or as an angle. Choose the cross-sectional shape that suits your construction.
- Square
- Rectangular
- Triangular
- Round
- Angle
i-type by groove form
Open or closed grooves. This determines from which sides you can attach add-on parts later.
- Open grooves
- 1 side closed
- 2 sides closed 180°
- 2 sides closed 180°
- 3 sides closed
- 4 sides closed
- Angle profiles
- Radius profiles
- Clamping profiles
- Sliding door profiles

item Profile: frequently asked questions and answers
Here you will find answers to the most common questions about our item compatible aluminum profiles — from dimensional equivalence and the right groove width to material and cut-to-length service.
If a question remains open, our team will help you personally. You can reach us Mon. to Fri. from 9 am to 5 pm on +49 9452 9334-0.
Are your aluminum profiles dimensionally identical to item profiles?
Yes. Our i-type profiles match the corresponding item series in groove width, grid dimension and groove geometry. You can therefore extend existing constructions or replace individual profiles without using adapters.
Do my existing T-slot nuts and connectors fit?
Yes, as long as the groove width matches. Accessories for groove 8 fit every one of our series 8 profiles, regardless of which manufacturer your existing parts come from. The same applies to grooves 5, 6, 10 and 12.
Which groove width do I need?
Measure the opening of the groove on your existing profile. The value in millimetres corresponds to the series: an 8 mm groove opening means series 8. This is the most widely used size in mechanical engineering. For a new construction, the choice depends on the planned load.
Which series suits my application?
Series 5 and 6 are suitable for covers, light frames and displays. Series 8 is the standard for machine frames, workstations and conveyor technology. Series 10 and 12 carry heavy constructions and safety enclosures. Series 8 XMS has closed grooves and is suitable for cleanroom applications.
What material are the profiles made of?
We supply profiles in Al Mg Si 0.5 F25, age-hardened. The surface is naturally anodised in E6/EV1 with a coating thickness of 10 to 15 µm; the dimensional tolerances comply with EN 12020-2. This makes the profiles corrosion-resistant and designed for continuous industrial use.
Do I receive the profiles cut to size?
Yes. We supply aluminum profiles cut to your specified lengths. This saves you rework and offcuts during assembly. We agree your required dimensions with you as part of your enquiry.
What is the difference between I-type and B-type profiles?
I-type and B-type denote two different groove geometries. The profiles on this page are I-type and therefore dimensionally identical to item profiles. If you would like to extend a construction made of Bosch Rexroth profiles, you will find the matching series in our category Bosch compatible type-B profiles.
Can the profiles be reused?
Yes. All connections in the i modular system are detachable. You can dismantle a construction and reuse the profiles in a new setup. Aluminum is also fully recyclable.
How do I obtain a quotation for my project?
For larger quantities or complete constructions we will calculate an individual quotation for you. Call us on +49 9452 9334-0, Mon. to Fri. from 9 am to 5 pm, or send us your enquiry via our contact form.
