Precision Quincy Industries offers three (3) pre-engineered packaged, sound-attenuated enclosure models designed for your standby or prime power generation application needs. Constructed of a roll-formed and welded steel frame, our pre-engineered enclosures utilize a proven automotive industry VHB adhesive. The adhesive bonds the aluminum or galvannealed steel skin to the frame to offer a smooth exterior finish, free of rivets, bolts, or other hardware.
