UNPARALLELED LTD is one of the leading manufacturers and suppliers of granite machine bed in China. With abundant experience, we warmly welcome you to buy advanced granite machine bed made in China here from our factory. We also accept custom orders.

Granite is one of the best materials available today to meet the ever changing and sophisticated applications demanding coplanarity, perpendicularity, parallelism, flatness, and straightness. It is often chosen for its stability and high accuracies. With UNPARALLELED® you can depend on excellent quality, high accuracies, and quick delivery. See our price list for sizes and accuracies of our standard products which can usually ship in less than a week. Major credit cards accepted.
We produce our granite products from several types of granite, depending on the customer's needs. Laboratory tests have shown that fine-grained black granites are stronger, denser, and less absorbent than other granites. For this reason precision machine bases, air-bearing surfaces and accessories are best made from black granite.
