Extruded vs Sintered Base on Skis & Snowboards

Updated October 5, 2023


Extruded and sintered bases are the two main types of bases used on skis and snowboards. The base is the bottom layer of the ski or snowboard, and it plays a crucial role in the performance and durability of the equipment.

Advantages of sintered bases

  • Tougher, more durable base
  • Holds wax longer

Advantages of extruded bases

  • Cheaper
  • Easier to repair

Extruded bases are made by forcing a mixture of heated plastic and other materials through a mold. This creates a base that is relatively soft and porous, which makes it easier to repair and maintain. Extruded bases are also less expensive to manufacture than sintered bases, which makes them a popular choice for entry-level skis and snowboards.

One disadvantage of extruded bases is that they are not as durable as sintered bases. The softer material can be damaged more easily by rocks and other obstacles on the slopes, which can cause scratches and other damage to the base. Extruded bases also tend to be slower than sintered bases, which can be a disadvantage for advanced skiers and snowboarders who are looking for maximum speed and performance.

Sintered bases, on the other hand, are made by pressing a mixture of powdered materials under high pressure. This creates a denser, harder base that is more durable and resistant to damage. Sintered bases are also faster than extruded bases, which makes them a popular choice for high-performance skis and snowboards.

One disadvantage of sintered bases is that they are more expensive to manufacture than extruded bases. This makes sintered bases more expensive for consumers, which can be a disadvantage for people who are on a tight budget. Sintered bases are also harder to repair and maintain than extruded bases, which can be an inconvenience for skiers and snowboarders who need to get their equipment serviced.

In general, the choice between extruded and sintered bases depends on the individual’s needs and preferences. Extruded bases are a good choice for beginners and casual skiers and snowboarders who are looking for an affordable option that is easy to repair and maintain. Sintered bases, on the other hand, are a better choice for advanced skiers and snowboarders who are looking for maximum performance and durability.

I've spent the last 25 year riding my snowboard all over the world. I now live in Switzerland with my family where I coach snowboarding and still get a few powder days whenever I can. Lean more about me here ->
