Material

zai is the worldwide leader in the use of new and revolutionary materials during the ski manufacturing process. Many of the materials we use are developed and patented by zai. Cut a zai ski (not that easy!), and you will find as different and exotic materials as granite, cedar wood, vulcanized rubber, felt, or flax. zai combines those in an innovative way and achieves such a level in terms of quality, use and durability, which is far higher than the properties of a conventional ski.

Stone

CFS® (carbon fibre stone) is developed and produced by the company TechnoCarbon Technologies. During the production, natural granite is injected with carbon fibres. Thus, the new material can be bent without breaking.The granite used in the zai CFS®- stone core…

Cedar wood

Cedar wood is light, form stable and torsion resistant. With its excellent tension, it returns to its original form after bending. The excellent firmness of cedar wood supports the uncompromising weight reduction of zai.Laminated cedar wood is used for testa,…

Walnut veneer

The surface of the zai testa is made of French walnut veneer. The high-quality wood is obtained from sustainably aforested tree populations. Walnut provides for natural absorption and contributes to the quiet running of the ski. The wood is very…

Carbon

zai uses UD (unidirectional) - continuous carbon textile fabrics. This fibrous material is applied by hand to the ski in different strengths, which permits precise control to the tension at strategic points. The pre-impregnated UD-carbon fibres are pressure-hardened afterwards during…

Steel

Upper edges zai is the only ski manufacturer to equip its ski with upper edges made of high-grade steel. The hardened HRC 50 steel is extremely durable and corrosion resistant. Steel upper edges protect the ski against shocks and impacts…

Natural rubber

Vulcanized natural rubber is extremely durable and is, therefore, extremely suitable for the ski surface. It becomes impact and scratch resistant and can be reworked without any problem. At the same time, rubber has absorbing characteristics. The cushioning impact on…

Felt

It may sound unusual that one uses felt in the production of ski. It is actually the ideal material, since it is durable, weatherproof, flexible and shock absorbing. For the production, these natural wool fibres are pressed by using a…

Nano-racing base

Every zai ski is equipped with the best high-speed racing base in the world. Nano-coated, pre-impregnated with wax, and manufactured with high graphite content, the exclusive surface provides for a ski with excellent turning properties. At the same time, it…

zaiíra®

The existing solutions with carbon composite materials were unsatisfactory for the ski production. zai developed and patented therefore zaiíra®. zaiíra® is an ultralight synthesis of the most modern strengthening fibres and thermoplastic compounds. It improves flexibility, stability and longevity. Particularly important:…

Cellulose-Acetat

In the history of the ski production, some attempts were made to use cellulose acetate. zai is the first manufactory which succeeded to successfully use this functional, natural and innovative material. Cellulose acetate is made from cleaned cellulose, the most…

dyneema®

While having the same weight, this plastic fibre is 60% stronger than carbon fibre, has an up to 15 times higher tensile strength than steel, and is, nevertheless, light enough to float on the water. At the same time, dyneemais…

Flax

Flax is the strongest natural fibre and is characterised by high resilience and abrasion resistance. These mechanical characteristics provide for the necessary firmness. A linen yarn keeps its diameter, if pressure is exerted perpendicularly to the longitudinal direction of the…
