Aluminium Profile AC 40-8, 40x40, with 1 groove

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 cut) and good resistance of the mutual connection in the transverse direction to the groove.

2. Joining with a continuous screw from the outside of the profile

This is the strongest method of joining, resistant to mutual movement between two profiles. This method of joining provides better perpendicularity of the joint (which, however, depends very much on the care taken in the quality of the cut). This system does not allow movement of parts in the event of screw loss. Drilling the hole can be done with a pistol drill with two diameters.

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.
