There is some overlap. Aluminum is used in large industrial cables for mining applications and power feed for large commercial buildings and condominiums. Aluminum is taking over copper because there's about a three to one price difference and it's lighter to work with and is readily available.
In our products aluminum is much less volatile in price so it is becoming more popular so the market is growing for aluminum cables. The cables are made in Canada to a CSA standard, and we have CSA inspectors in our factory every week. I don't know if they go to other factories in other countries and I don't know if they're checked at the ports. CSA walks our factory floor to make sure the cables are being made to standard. Again, we only use North American raw materials so we're very confident in the quality of the raw materials.
