Boston Steel has been building tanks for the fuel transport industry since 1915. With over a century of experience, our manufacturing ingenuity and attention to detail has earned us the reputation for exceptional quality. Wherever a Boston Steel tank drives the road, people take notice. At the ripe age of 99 years, the company was purchased by Tremcar USA, a dedicated tank-trailer manufacturer. Located in Haverhill, MA., the company is now a full parts and service facility assembling tank trucks and trailers for the North American market.
