HPL Composite panel fixing system with visible rivets.

This system is most used for administrative and office buildings. The main advantages of rivets are:

– fast and easy installation.

– it is possible to remove the cladding boards for any reason (installing video surveillance, air conditioner, facade lighting) just over-drill the rivets, demount the boards and then mount again with new rivets.

–  vibration proof system, providing long life for your facades.

– free thermal expansion and contraction of the boards (panels).

Special Blind RivetsSpecial Blind Rivets

Specially designed blind rivets are used in this system. In order to ensure long and hassle-free usage the mandrel and the body of the rivets are made of high corrosion resistance materials.

The rivets have best-looking shape design, with very thin head (less than 1,6 mm).

Two component, scratch resistance coating is applied in any RAL color to match the cladding boards.

Rivet specifications:

The standard length L=16 mm. (other lengths are possible by request).

Rivet strength:

Shear strength: 2107 N ± 10%.

Tensile strength: 2842 N ± 10%.


Body:  Aluminum AlMg3,5

Mandrel:  Stainless Steel A2


To ensure free thermal expansion and contraction of the boards there is a typical method of drilling.

Floating points:


Fixed points:



Each hole for the exposed fixing board’s holding rivets must be 3 mm larger than the diameter of the rivet used, except the hole at the board’s geometric centre, witch must be the same size as the rivets. This hole is called fixed point and the other (bigger) holes are called floating or free points of fixing.

 Floating and fixed points positioning:


 Floating and fixed points positioning (variant 2):


4,9 mm. pilot hole required in the composite panel for fixed point. All other holes depend on material. Check the attachment method instructions provided by the cladding panel manufacturer.

Additional accessories:

Special nosepiece for standard rivet tools.
