At KEYSTONE, quality begins in the factory and is maintained all of the way to your destination. Shipped fully assembled, we deliver prefabricated buildings anywhere in a 300 mile radius, using our own delivery equipment. All prefab buildings are pre-wired and meet the requirements of BOCA and NEC. KEYSTONE maintains a third party inspection agency, and at a customer's request will furnish engineering drawings complete with the state seal and signature ready for submission by customer to acquire permit approval.

To insure quality control, and guarantee availability of replacement parts, we manufacture our own standard components including replacement panels, sliding aluminum doors and windows. KEYSTONE provides the widest range of products in the pre-assembled building and structure field and consistently incorporates innovative features which become standards in our industry.
