Optionally, and upon request, we can supply propellers, shafts, brackets, rudders, etc. made in other alloys and strenghts. |
Control and certificates of approval from Classification Institutes.
We make quality and strength laboratory controls of the materials (bronze and stainless steel) used in the manufacture of propellers and shafts. Also, if required before casting and machining, we can make the corresponding laboratory assays in order to pass the controls of the main approval organizations (I.B., LLOYD'S REGISTRE, BUREAU VERITAS; etc.). |
