Joining profiles
The choice of fixings between different profiles is very important in any assembly structure. The customer can choose from various solutions depending on the required implementation time or the nature of the load or load-bearing capacity.
1. Joining with screws in the groove
This is the simplest and fastest way to assemble. This connection system guarantees good perpendicularity between two surfaces (depending on the profile section) and good resistance of the mutual connection in the transverse direction to the groove.
2. Joining with a connecting latch
This assembly is very simple and safe and guarantees a firm connection even if the screws are loosened.
3. Joining with joints or angles
This method of joining is usually used where the greatest possibilities of adjustment and easy installation are required. Technical specifications for all products can be found in the product details of the relevant accessory.
Profile threads
It is recommended to respect the depth indicated in the table when creating a thread:
| Profile | Screw diameter | Recommended depth (mm) |
| slot 6 | M6 | 15 |
| slot 8 | M8 | 25 |
| slot 10 | M12 | 30 |
The maximum tightening torques recommended for screws used in the ALUSIC system are:
| Profile | Screw diameter | Max. recommended tightening torque (Nm) |
| slot 6 | M6 | 10 |
| slot 8 | M8 | 20 |
| slot 10 | M12 | 35 |

How to choose profiles and parts
1. Choose a series
Stick to one series. Bolts, nuts and connectors must match the slot shape of the profile.
2. Choose the size
Choose the section and version by the load: thin and light for frames and guards, heavy for load-bearing structures.
3. Connect
Join the profiles with brackets, connectors or joining plates and slide the nuts into the slot.
4. Complete
Finish the structure with end caps, feet or castors, panels, doors and LED lighting.
Frequently asked questions
- What is the difference between the AC, BH and IM series?
- The slot shape and the sizes. Some parts fit several series, but always check which slot they are made for.
- Is there a profile catalogue in Czech?
- Yes. The AC, BH and IM series categories and the HT LED lighting category contain the maker’s catalogue in Czech as a PDF.
- What do thin, light and heavy profile mean?
- Profiles with the same section and slot differ in wall cross-section. A heavy profile carries more, a light or thin one saves weight.
- How do I fit an LED light into a profile?
- The HT light goes straight into the 8 mm slot and connects to a power supply. Choose the supply by the light length, for example 20 W for lengths of 250 to 1000 mm.
- How do I drill profiles accurately?
- The Profile machining categories contain drilling jigs that set the drilling position, drills and adhesives for bonded joints. The maker can also machine profiles automatically from STEP files.
- Does ALUSIC make other systems too?
- Yes. The maker also has the EVO SP system for safety guards, IS stairs and platforms, carbon fibre profiles, conveyors, linear axes, overhead crane runways, lean manufacturing tubes and joints, solar mounting structures and SICOMAT compressed air piping.
Catalogues in Czech for the AC, BH, IM series and HT LED lighting can be downloaded in the series categories. The maker publishes company and product videos on its YouTube channel.
