Structure<br />
Structure<br />
When the base of a snowboard or ski has a<br />
certain surface structure, or texture pattern,<br />
the gliding performance is improved compared<br />
to a completely smooth base surface.<br />
It is impossible to classify the infinitely<br />
variable types of snow and the unlimited number<br />
of possible structure patterns.<br />
However, for practical purposes, structures<br />
can be grouped into three primary classifications:<br />
• Fine Structures<br />
• Medium Structures<br />
• Coarse Structures<br />
Structures and Snowtypes<br />
FINE STRUCTURES<br />
Fine structures are used mainly on new snow<br />
and fine-grained snow from 0°C and colder.<br />
Also used on older fine-grained snow from<br />
approx. -8°C and colder.<br />
MEDIUM STRUCTURES<br />
Medium structures are used near the freezing<br />
point 0°C (32°F) in a range of about +4°C to<br />
-6°C with older fine grained snow.<br />
COARSE STRUCTURES<br />
Coarse structures are used when the snow has<br />
gone through one or more cycles of thawing<br />
and re-freezing and/or in a melting state around<br />
freezing and we have coarse grained snow<br />
crystals. Typical snow temperatures are 0°C and<br />
air temperatures in a range of 0°C to +10°C.<br />
