At Pierce Manufacturing, we build trucks that protect people and communities around the world. To our team, there is no room for anything less than providing the absolute best. Since 1913, building truck bodies on Model T Ford chassis in an old converted church has evolved to creating highly customized, carefully designed and engineering pumpers, aerials, tankers and rescue units that have no equal. Today, you'll find more than 30,000 Pierce apparatuses on the road that are making a difference in people's lives, every day. To us, every step in the process of building our trucks is personal. From innovation and expertise, to the customization and service. Our trucks are designed to perform under the toughest conditions.
