DomCast Metals is a Canadian-owned municipal castings supplier based at 5255 Cabana Road E in Windsor, Ontario, serving the waterworks market for 80+ years. Municipalities, contractors, and waterworks distributors across the province order manhole covers and frames, catch basin frames and grates, valve boxes, sewer grates, cleanouts, and curb boxes from a 193-SKU catalog, and we ship across Ontario and into the United States.
Built around how Ontario tenders are written
Ontario road and sewer tenders call out castings by OPSD drawing number and load rating. Our catalog is organized the same way: the catch basin and manhole lines are listed under the OPSD 400- and 401-series pattern numbers, with Thunder Bay, Ottawa, MTO, and Eastern Canada variants stocked alongside. Send the drawing number and quantity and we quote against it; conformance to a specific drawing is confirmed per SKU.
What we supply
- Manhole frames and covers — solid, perforated, storm/sanitary marked, airtight patterns
- Catch basin frames, covers and grates — dished, flat, V-type, fish-style, bicycle-proof, side-inlet

Reference tools for spec writers
