All internal parts are protected with protective anti-rust oil.
Unless otherwise agreed in the order, products are adequately packed: on pallet, protected with a polyethylene
fi lm, wound with adhesive tape and strap (bigger sizes); in carton pallet, wound with adhesive tape and strap
(smaller sizes); in carton boxes wound with tape (for small dimensions and quantities). If necessary, gear
