Quality policy

Experience
We have over 60 years of experience in both the manufacture and repair of propellers.
Background
With the rise in metal prices, propeller repair has become an economic necessity. The increase in repair demand, including several contracts with the U.S.C.G. to repair its propellers and CPP blades, speaks highly of the confidence our clients have in the quality of our repair services, therefore, we decided to create new facilities and infrastructure exclusively for this purpose.

We use state-of-art technology and highly-specialized staff to make our repair processes more efficient and precise.

Repair process
Repairs may be done in-house, afloat or on site.
A preliminary diagnostic test is done of the condition of the propeller, to determine the best work strategy to use according to the damage or modification to be done, which may include: pitch correction, thicknesses, widths, implants, balancing, etc.
