and you will receive our quote.


grafene weeween

We are the first on the market that use Graphene
in the aircraft painting and coating components.

The result is to make 
treated surfaces more protected,
waterproof and resistant to weathering, corrosion
and chemical attack.


A derivative of graphite, composed of a single layer
hexagonal arranged carbon atoms.

A futuristic nanotechnology material for
its revolutionary properties:
flexible, ultrathin, easily and at the same time
very good electrical and thermal conductor
as well as resistant as diamond.

X-RAY EXAMINATION                        
raggi x weeween

We perform professionally X-Ray inspection for parts
assembled by us and damaged parts; this analysis allows us
to check substructure, tightness and functionality.

We have the most advanced scanning technology to ensure
maximum quality and transparency.



laser weeween

We use the Laser machine for cutting plywood and
for metal engraving.

This system allows us to do 
the highest precision, fast and clean job.


ricambi weeween
We meticulously build any spare part you need for your aircraft.

Share us to
the identity of the missing spare part
and we shall offer you a concrete solution for it.
