# Doepker Industries Ltd. > Saskatchewan-built heavy-duty trailers since 1972. Engineered for the demands of western Canada and beyond. Doepker Industries is a Canadian manufacturer of heavy-duty trailers headquartered in Annaheim, Saskatchewan (founded 1948, trailer manufacturing since 1972). Doepker trailers are engineered and built in Saskatchewan and sold through a dealer network across Canada and the United States. In 2025, Doepker acquired Peerless Trailer and Scona Trailers, expanding its family of North American trailer brands. ## Why Doepker - **Customer Driven** — Every trailer is built to the spec that haulers actually need, shaped by operator feedback and decades of working alongside Canadian fleets. - **Strongest & Lightest** — Proprietary high-tensile steel construction and zinc galvanizing deliver the best strength-to-weight ratio in each class. The Doepker Classic Steel Super B weighs roughly a ton less than comparable aluminum trailers with identical options. - **Innovative Engineering** — Doepker introduced the first open-end bulker on the market in 1997, a design that the industry adopted and still follows. 300+ signed inspection points on every trailer. - **Highest Resale** — Doepker trailers command the best resale value in their class, recognized by operators and dealers across Canada. - **Proven Under Pressure** — Doepker trailers operate in the harshest Canadian conditions: prairie grain hauls, northern logging, oilfield service, and heavy-haul construction. ## Products by Category ### Agriculture / Commodity Grain Trailers - [Classic Steel Super B](https://doepker.com/trailers/grain/super-b-grain): The workhorse of the Canadian prairie.
