Ski base structure: what it is for and how to make it
Structure is the micro-pattern cut into the base after grinding. It determines glide depending on the snow. Here is how it is made in the workshop and what the catalogue machines offer.
Why put structure into a base
A perfectly smooth base tends to stick on wet snow. The fine grooves of the structure help evacuate water and keep good glide. Structure is therefore adapted to conditions: more pronounced for wet snow, finer for cold, dry snow.
Stone or belt
Structure is made on a stone grinder or, more simply, on a belt grinder. The PROFI S 200 Racing and PROFI S 350 Racing stone grinders list 33 pre-programmed structures, a structure advisor and a memory space for your own structures. The PROFI B Vario makes structure with a belt, using VARIO ceramic belts and a patented Reichmann universal cross structure.
The Profi 4 Racing brings belt and stone together and includes an on-screen structure simulator. The comparison of belt or stone grinder puts the sheets side by side.
Automating structure
The robots store complete programs: the Slope Master S Race offers about 60 finishes and 18 factory pre-grinding structures, and the SF-4 Race lets you create your own programs with a built-in structure simulator.

Frequently asked questions
Can you put structure into a base without a stone grinder?
Yes, a belt grinder fitted with structure belts can do it. The manufacturer presents the VARIO belts of the PROFI B Vario as giving a result comparable to stone grinding.
Are the structures the same for alpine and nordic skis?
No, the machines offer separate libraries: the PROFI S lists alpine and cross-country race structures, the Profi 4 alpine, nordic and snowboard structures.
