I am interested in a range of your cylinder head gaskets to be a permanent addition to our product range. But as we are a automotive perfomance business, oem materials will not suit our customers needs. Are you able to produce gaskets in steel and or copper? With a thickness of 1.5mm, 2.0mm, and 2.5mm? In your reply if you could please include (if applicable) min order shipping cost? dilivery time after order? payment and sample policy, and any other relevant info I may have neglected.
