Casting
|
 |
Tyco Fire & Building Products produces ductile iron, ASTM A-536, Grade 65-45-12 for all of its Grinnell® Grooved Products. Once the base iron is produced, magnesium is added in precise measurements to develop the ductile iron grade. The metal is tested chemically, physically, and microscopically prior to being released for production. Once cast, the ductile iron is again checked to ensure conformance with these specifications.

Rubber Injection
|
 |
Tyco Fire & Building Products understands the complexity of providing gaskets capable of exceeding customer demands. With state of the art rubber injection presses and tooling, we are able to mold several types of rubber compounds to meet the various needs of the mechanical market. The gaskets are manufactured in our facility in Alabama and each gasket is inspected to ensure it is defect free. Physical tests are performed on the gaskets to verify compliance with specifications such as ASTM D-2000.

The Paint Process
|
 |
Grinnell Grooved Products are painted using a computer controlled semi-automatic process. This process ensures that each product is spray washed, dried, pre-heated, dipped and fully cured prior to being assembled or packaged for shipment. All painted parts are quality controlled to maintain consistent paint coverage and surface condition.
