Copper earth rods

prospecting
Good morning.

Please excuse me for I have not mastered English well.
I just started a business in France (Angers) and I prospected for some customers in the Maghreb countries. My focus is on products for grounding (ground grid of copper, copper earth rods, flat tinned copper 30x2 and other accesories), bolts galvanized (12 to 22mm diameter) and leaves and socks that can absorb the products of hydrocarbon (oleophilic hydrophobic).
Greetings and thank you in advance.
