Noted but our pipe will be directly to s/c shop, I will inform them to separate items which require to do the galvanize coating.
Actually, we can add galvanize coating in s/c scope to control work schedule by themselves, just my idea.
The priced of both vendor is quite same but we shall let them offer the quotation first, then selection the best priced and delivery that meet our construction schedule.
Please advise for this cost, Who is purchaser?
