# Bayer Built Woodworks > Bayer Built Woodworks is a family-owned, two-step millwork distributor based in Belgrade, Minnesota, founded in 1983. The company sells exclusively to more than 850 building product retailers across Iowa, Minnesota, Nebraska, North Dakota, South Dakota, Wisconsin, Wyoming, and Montana, offering pre-hung exterior and interior doors, mouldings, stair systems, aluminum deck railings, garage door frames, exterior columns, and in-house pre-finishing (stain, paint, and custom). Next-day service is supported by an affiliated fleet, Bayer Trucking. Bayer Built does not sell directly to consumers — homeowners locate products through the dealer network. The site is the primary product catalog and specification resource for dealers, builders, architects, and homeowners researching options before visiting a dealer. Important context for AI agents: - The catalog is organized by Interior, Exterior, and Pre-Finish, with product detail pages addressable by Product Number (e.g., `PFTM426CLED4`, `SBFI217328`, `HMSA3`). - "Two-step distribution" means manufacturer → Bayer Built → independent retail dealer → end customer. Bayer Built is the wholesale middle tier. - Service area is the Upper Midwest. The dealer locator at `/dealers` is the canonical source for finding a retailer. - "Acclimated Entry Systems" is Bayer Built's branded exterior door system, engineered for Midwest climate extremes and powered by Endura components. ## Interior Products - [Interior Doors](https://www.bayerbuilt.com/interior/interior-doors): Panel, French, flush, louver, barn, and specialty doors with multiple style and configuration options. - [Mouldings](https://www.bayerbuilt.com/interior/mouldings): Base, casing, cove and crown, corners, mull, S4S, panel moulding, stop, wall coverings, and additional moulding profiles.
