The aluminum coated conical drum is made of steel coated on both surfaces by means of continous inmersion in an aluminum alloy bath.
The coating alloy protects the steel from environmental corrosion even in the presence of elevated temperatures of exercise.
The mechanical characteristics remain unchanged as well as the filling and emptying systems.
The main purpose is to protect the drums from environmetal corrosion. The drums are 3 times more corrosion resistant than those made of painted steel . Drums are ecologically friendly, since varnishing products are eliminated. |
