Building designers have always been reluctant to put any mechanical systems on top of roofs. This is mostly due to how chilled water piping, gas lines, steam lines, duct and equipment have to be supported. Typically, supports will be placed on a roof that will penetrate the roof membrane and attach to structural steel. These penetrations will have to be waterproofed either by flashing or pitch pockets. On a roof with many support penetrations it only takes one faulty flashing to allow a roof to leak.
PHP Systems & Design offers a system of designed supports that minimizes roof penetrations while spreading out the dead weight to 2 p.s.i. or less. MKT has partnered with PHP for years and is proud to offer this complete engineered system to its customers.
Established in June of 2004, MKT was created to be a valued manufacturer/supplier of sheet metal duct, spiral duct, roof curbs, coated duct and HVAC duct accessories that customers can consistently rely upon.
