Dear Mr Sales Manager,
We have obtained your name and address from Internet, and we are writing to inquire whether you would be willing to establish business relations with us.
We have been manufacturing aluminium door and window, and curtain wall for many years now. At present we are interested in expending our overseas market and would appreciate your response.
Considering our competitive prices, we expect to establish long-term partnership with you.
We look forward to your early reply.
With best regards
Scott
