We produce any kind of drill rods , all with working lengths up to 3 meters and thicknesses up to 12.5 mm . For the sleeves of our auctions we use hardened steel in 42CD4 , then heat treated to prevent seizure ( gas nitriding ) , to improve its mechanical properties. We are highly specialized in the production of drill rods for jet grouting :
Jet monofluid : diam. 50-140.
Jet dual fluid : diam. 90-140 .
Jet triple fluid : diam. 90-140 .
We also designed and developed a special battery and rotary percussion drilling ( with hammer head) and for injection of cement ( for use of reeds in manchettes ) .
