About GBM's formwork panels

GBM formwork 3ply panels are built with three layers of wood obtained from fir and spruce trees grown in sustainable forests.

STRUCTURE:

Our panels are made with a 3-ply structure 9+9+9 mm, without frame.
This means that the mechanical properties of our panel are the same and unchanged even if you cut the panel.
The outer plies that are in touch with the concrete are thicker (9mm vs 6mm) and will allow the panel to last longer.
Lamellas of GBM panels are prepared from a glulam monolitic beam having a smaller width which improves the resistance of the panel and automatically reduces the maximum dimension of accepted knots.

SURFACE FINISH:

Our panels have a melamin finish, just like other panels, but having a greater quality of raw material we can provide it with natural color finish. Of course we can also provide with the classic yellow finish.
The reason why yellow is used is to cover possible aestethical defects of the wood, because yellow tends to uniform the view.
We are sure enough of our quality that we offer it with natural finish. This finish is also optimal for at sight concrete.

EDGES:

We are introducing a polyuretane protection on the longitudinal edges as an optional. This option will allow a perfect smooth contact of the panels edges and it will improve the concrete finish.

CUSTOMIZATION:

We can customize our panels with the following options:

  • Name printed on the top face of each panel - standard will be with day and hour of production for perfect production tracking;
  • Name / logo printed on each bundle
  • Selection of colors for the edges.

A GBM panel loading diagram

The diagram shows how the panel reacts upon loading, considering the interval spaces between one support element and the other.

Q stands for uniform load (in kN/ m2 unit).

I stands for interval space between the support elements.

f is the folding calculated in mm.
