Who We Serve

Built for Miami-Dade Contractors

From Doral to Hialeah, from Coral Gables to North Miami — we supply the PT lumber your projects actually require, in the sizes and quantities that keep your crew moving.

Deck & Outdoor Contractors

Pool decks, pergolas, and outdoor structures demand the right treatment level. We carry above-ground and ground-contact rated decking boards, posts, and framing — in the widths your designs call for.

  • 5/4×6 deck boards — in stock
  • 2×6, 2×8 joist framing
  • 4×4×8 through 6×6×16 posts
  • Ground-contact post bases available

Fence Contractors

Miami-Dade has over 1,000 active fence companies. We keep volume post inventory so you’re never waiting on 4×4 stock. Open a trade account and get contractor pricing on every order — same day or next day.

  • 4×4×8 & 4×4×10 posts — in stock
  • 1×6×16 privacy fence boards
  • 2×4 fence rails
  • Volume pricing on 50+ pieces

Landscapers & Hardscape Contractors

Retaining walls, raised planters, trellis systems, and pergola structures all require PT lumber that can withstand South Florida’s heat and humidity. We stock what you need, when you need it.

  • 4×4 & 6×6 landscape timbers
  • Retaining wall stock
  • Raised planter box lumber
  • Trellis & pergola framing
Why International Plywood

Not Your Big-Box Lumber Yard

Home Depot won’t deliver 200 posts to your job site. They don’t stock 6×6×16 lengths. They don’t offer volume pricing for contractors. And they treat every customer the same — whether you’re buying 5 boards or 500.

We’re a wholesale distributor with over 43 years serving South Florida’s trade community. That means better prices, real inventory depth, and a direct line to a sales team that knows your project before you explain it.

Common Applications

Where Miami Contractors Use Our PT Lumber

From new construction to renovation, these are the projects our trade customers run every week across Miami-Dade and Broward.

🏠

New Home Construction

Florida code mandates PT for all bottom plates, sill plates, and lumber within 8″ of grade or concrete. We spec full material lists for GC accounts.

2×4 / 2×6 bottom plates · 3/4″ PT CDX sill · 4×4 posts
🏔

Pool Decks & Patios

Pool-adjacent decking requires ground-contact rated lumber. We stock the full deck framing package — joists, beams, posts, and deck boards — ready for same-day pickup.

5/4×6 deck boards · 2×8–2×12 joists · 4×4 / 6×6 posts
🌏

Privacy Fencing

Miami-Dade’s volume fence market demands reliable post supply. We keep 4×4×8 and 4×4×10 in bulk stock — open an account and we hold inventory for your schedule.

4×4×8 / 4×4×10 posts · 1×6×16 boards · 2×4 rails
🌳

Pergolas & Shade Structures

Outdoor living structures in South Florida need treated lumber that handles year-round heat and humidity. We stock the large-dimension timbers most yards don’t carry.

6×6×8–16 posts · 2×6 / 2×8 rafters · 4×4 knee braces
🏠

Additions & Renovations

Tie-ins to existing foundations require matching PT framing. We match the grade and treatment level required by your permit set — just send us the spec sheet.

Commercial & Multi-Family

Large commercial projects get dedicated account pricing, scheduled delivery, and a single contact for the full project scope — not a retail counter experience.
