Our plywood inventory supports builders and cabinetry makers with dependable stock, clean faces, and flexible core options. Standard panels, custom layups, and specialty sheet goods—sourced to meet the demands of construction and production environments.
At Mason’s Mill & Lumber, plywood isn’t an afterthought — it’s a working material. We stock and source sheet goods that builders and cabinetry makers rely on every day, with the consistency, face quality, and core options required for real jobsite and shop conditions.
From domestic NAUF and ULEF panels to specialty outdoor and moisture-resistant options, our inventory is built to support production schedules, not slow them down.
For projects that need more than an off-the-rack panel, we offer custom plywood solutions through our sourcing and manufacturing partners.
Custom capabilities include:
Custom veneer layups
Different faces on each side (species-to-species or veneer to melamine)
Pre-finished custom panels
Cut-to-size options (within project scope)
These solutions are typically handled job-by-job, allowing builders and cabinet shops to dial in exactly what the project requires — without over-ordering or unnecessary compromises.
If your project needs something specific, our team can help spec the panel before it ever shows up onsite.
The traditional line is solid Poplar milled from clear, kiln-dried hardwood - the working backbone of the White River catalog. Crowns, bases, casings, chairrails, and panel moulds are drawn in coordinated proportions and precision machined on Weinig moulders, so profiles stack and return cleanly against each other.
Stock is NHLA graded and kiln-dried to 6-8% moisture content, with coordinating accessories, blocks, plinths, and dimensional lumber available to complete the package.
