Reclaimed Douglas Fir Beam
Hand-hewn, authentic patina, sourced from Pacific Northwest barns. Cut to your spec.
For nearly a decade, contractors, builders and homeowners across California and the West have trusted Grandpath Supply to deliver premium lumber, stone, hardware and renovation supplies — on time, every time.
Grandpath Supply LLC started in Arcadia, California with one truck, one forklift and a promise: hand-picked building materials, priced fairly, delivered when we said we would. That promise still drives everything we do.
From reclaimed Douglas fir beams to contractor-grade hardware, we curate a catalog that tradesmen love and architects specify. Whether you're framing a custom home in Malibu, restoring a craftsman in Pasadena, or ordering specialty tile across the country — we've got your back.
From a single box of nails to a fully staged residential development, we provide everything between the foundation and the front door.

I called on a Friday, had a quote Saturday morning, and my tile was on a pallet headed to Texas by Tuesday. The level of service is just different.
Grandpath knows stone. Their team walked us through three pallets before we settled on the right ledger. That's how you build trust in this industry.
