Operating from our Lighthouse Point location, we specialize in wholesale distribution of plywood, OSB, and specialty panels to meet the demanding needs of commercial and residential construction projects throughout the Baltimore metropolitan area.

Our extensive inventory includes structural plywood in various grades and thicknesses, oriented strand board (OSB), wall and roof sheathing, subflooring panels, pressure-treated plywood for exterior applications, and specialty panels for unique construction requirements. We stock standard 4×8 sheets as well as custom sizes, with span ratings and exposure ratings clearly marked to help contractors select the right materials for their specific applications.

Unlike big box retailers that cater to DIY homeowners, we focus exclusively on the professional trade, offering competitive wholesale pricing, bulk ordering capabilities, and the technical expertise that contractors need to keep their projects on schedule. Our staff understands the difference between CDX and OSB, can recommend the right thickness for your span requirements, and provides the personalized service that large chain stores simply cannot match.

Baltimore’s robust construction market, from Inner Harbor developments to suburban residential projects, demands reliable suppliers who understand local building codes and weather conditions.

Serving the Baltimore, Maryland Area

Baltimore’s construction industry benefits from a mix of historic renovation projects, new residential development, and commercial construction throughout the metro area. The city’s proximity to the Chesapeake Bay creates demand for marine-grade and moisture-resistant materials, while the urban density requires suppliers who can efficiently serve contractors working on everything from Federal Hill townhouse renovations to new construction in developing neighborhoods like Port Covington.

Tips for First-Time Buyers

  • Bring your project specifications including span requirements and exposure conditions to get the right grade recommendations
  • Call ahead for large orders to ensure material availability and arrange loading assistance
  • Ask about delivery options for job sites, especially for multi-sheet orders that exceed truck capacity
  • Verify grade stamps and span ratings match your structural requirements before leaving
