Joining techniques

Connection technology for stable aluminum profile constructions
Our fasteners enable the precise and robust construction of profile frames, racks, machine enclosures, and factory equipment. All products are designed for 8 mm slot profiles with a 40 mm grid and are compatible with systems such as Item or Bosch Rexroth.

Efficient assembly – permanently connected
Whether automatic connectors, quick connectors, T-connectors or profile angles – our components offer maximum stability with minimal assembly effort. Many connections can be made without tools or with just a few simple steps.

Typical applications:
– Construction of machine frames and protective enclosures
– Manufacturing of workstations, shelves or material trolleys
– Extension of existing profile constructions
– Joining multiple profiles at a miter or angle

FAQ

What are aluminum angles suitable for use with aluminum profiles?


Aluminum angles connect profiles at a 90° angle, ensuring a stable and right-angled connection, e.g. in frames or racks.

Can aluminum angle brackets be retrofitted?


Yes, they can easily be retrofitted using suitable T-nuts.

What sizes are available?


Aluminum angles are available in various lengths and drilling patterns, suitable for 30 mm and 40 mm grids.

What are the advantages of automatic connectors?


They enable fast, stable connections without drilling and are almost invisible.

For which profiles are automatic connectors suitable?


They fit groove 6 and groove 8 profiles in a 30 and 40 grid.

How are automatic connectors installed?


Simply slide the T-nut into the groove and secure it with two screws.

When should I use bolt connectors?


When a concealed, high-strength connection within the profile is required.

Do I need to modify the profiles for bolt connectors?


Yes, in most cases a core hole drilling is required, which can be done with a standard metal drill bit.

What are the advantages of bolt connectors?


Very stable, space-saving and visually unobtrusive.

What is the difference between corner brackets and aluminum brackets?


Corner brackets are usually more compact and cheaper, while aluminum brackets are often more stable.

When do I use corner brackets?


For simple 90° connections under light to medium loads.

What do I use joints for in profile construction?


For movable structures such as doors, flaps or adjustable brackets.

What types of joints are there?


Standard joints, ball joints and adjustable joints for flexible applications.

What is a screw connection?


A direct connection of profiles via a screw, without additional components.

What are the advantages of a screw connection?


Low material requirements, concealed connection, very stable.

When do I use steel angles instead of aluminum angles?


For particularly high loads or when additional stability is required.

Are steel angles rust-free?


Stainless steel angles are corrosion-resistant, galvanized angles offer additional protection.

What is a universal connector suitable for?


It allows flexible connections at different angles, not just 90°.

Is it possible to retrofit universal connectors?


Yes, they can easily be integrated into existing profiles.

When do I use cube connectors?


For connecting three or more profiles at one corner.

What are the advantages of cube connectors?


They save time during assembly and ensure high stability in all directions.

What is a central connector?


A connecting element that brings profiles together in the middle and fixes them in place.

What is it used for?


Especially for frames and structures that are to be screwed together in the middle.

What are zinc angles suitable for?


For light to medium connections when a cost-effective, stable angle is needed.

Are zinc angle brackets corrosion-resistant?


Yes, the material makes them robust and durable for indoor use.
