Our country is not only surrounded for thousands of kilometres by sea, but it also features a great number of lakes, large and small rivers, connection waterways and drainage channels. The coastline and waterways need to be maintained by cleaning and clearing the bottoms and shores.

Waves, climate changes, weeds and last but not least waste, must be removed and disposed of to sustain the environment, allow navigation and prevent putrefaction, which causes great variations in the ecosystems of fish and of the coral reef.

Furthermore, in certain rivers and lakes, the bottom must be constantly dredged to keep them navigable. This is achieved by building Rafts and Pontoons equipped to dredge the beds and bottoms of the sea, waterways and lakes.

Dredgers work in a humid and heavy-wear environment; therefore, they must be built with particular steels that resist to the constant abrasion of different types of sand, gravel and rocks.

In addition, these machines collect the sand recovered from fresh water, which is employed in the building sector for the conglomerates used for plaster and gravel used for concrete.

The hull of a dredger, large or small, does not need to be manufactured with particularly specific construction steels, however the equipment in contact with the heavy-wear environment must be sufficiently resistant to carry out the work in a continuous way and to maximise the maintenance time, therefore they require the use of Wear Resistant Steel.

  • Clamshell buckets
  • Bucket with grille
  • Scrapers
  • Impellers and Turbines

These items must be manufactured with Wear Resistant Steel using parts obtained with an oxy-fuel cutting process, with Brinell hardness HB 400 – 450 – 500.
