GRP and Al structure
STEM MARINE boats can be realized both in reinforced GRP and in aluminum alloy.
For GRP boats we use the best resins available on the market and layered fiberglass with mono- and bi-axial fabrics reinforced with Kevlar in order to enhance resistance in case of collision.
All boats of GRP range are moulded with vacuum infusion in order to guarantee maximum resistance and minimum weight and no osmosis creation.
This technique guarantees respect for the environment thus reducing to a minimum the emission of styrene in the environment.
Aluminum boats are made of alloys for naval use and with certified welding procedures.
The welding department is strictly protected by atmosphere which might contaminate the aluminum during welding and guaranteeing the best product finishing and quality.
