When project managers and procurement teams beeline for durable panels, they search for one clear option: marine plywood 1220×2440 mm. This panel size fits common international workflows, reduces cutting waste, and delivers reliable performance for boats, cabinetry, and exterior works. In this article, I walk you through practical benefits, common thickness choices, certifications that matter, and where to source panels that perform.
What distinguishes marine plywood from regular plywood
Marine plywood uses high-quality veneers and strong waterproof adhesives. Manufacturers befriend phenolic or WBP glue to resist delamination and fungal attack. Buyers pick marine plywood when exposure to moisture or fluctuating humidity could ruin a standard panel. The result: longer service life and fewer callbacks.
Why 1220×2440 mm (4×8 ft) serves as the industry standard
The 1220×2440 mm dimension (4×8 feet) matches most global workflows. Shops cut panels more efficiently because layouts fit standard furniture parts and boat components. Freight teams load containers with less wasted space. In short: this size saves labor, reduces scrap, and speeds installation.

| Primary applications | Boat hulls & decks · Exterior joinery · Kitchen cabinets · Decorative panels |
How industries use marine plywood 1220×2440 mm
Boat builders install these panels on hulls, stringers, and decks because the panels balance weight and strength. Furniture makers prefer the smooth Okoume faces for laminating and painting. Contractors apply marine plywood in wet-zone joinery and external cladding where a standard panel would warp. Transport manufacturers use the panels for stable flooring and partitions that withstand heavy loads.
Pick the right thickness for the job
Choosing thickness remains the single most important decision. I recommend the following starter guide to match strength to function:
- 3–6 mm: Use for veneers, lightweight linings, and decorative overlays.
- 9–12 mm: Opt for general furniture, cabinetry, and interior joinery.
- 15–18 mm: Choose for decking, structural partitions, and heavy-duty furniture.
- 21–25 mm: Apply where structure demands high load capacity, such as boat floors or exterior substrates.
Which certifications matter for B2B buyers
Buyers prioritize certifications because they reduce compliance risk. Request BS 1088 when you supply marine projects that require specific marine standards. Ask for FSC documentation when procurement teams need traceability and sustainable sourcing. Confirm CARB and EPA TSCA Title VI for low-emission panels that meet North American regulations. When suppliers show these certificates, teams feel secure about product performance and regulatory fit.
Surface finish, glue type and core construction — quick comparison
| Attribute | Phenolic / WBP | Melamine-Phenolic | Standard Plywood Glue |
|---|---|---|---|
| Water resistance | High | High | Low |
| Recommended use | Marine & exterior | Marine & high-moisture interiors | Indoor, dry areas |
| Cost | Higher | Higher | Lower |
Where you can source reliable 1220×2440 mm panels
Procurement teams find steady supply in China, Malaysia, Indonesia, and Gabon. Suppliers in these regions offer large-scale production, and many provide CIF or FOB logistics terms. Vet suppliers for monthly capacity, inspection reports, and sample panels before placing bulk orders. Ask for product photos, test reports, and clear MOQ and lead time terms to avoid surprises.
Cost drivers and tips to control budget
Price depends on veneer species, glue type, thickness, and certification status. To control cost, specify required certifications only when you need them. Order standard sizes like 1220×2440 mm to reduce cutting fees. Consolidate shipments and ask suppliers for consolidated container pricing to lower per-panel freight costs.
Final recommendations for procurement teams
Choose marine plywood 1220×2440 mm when you need panels that combine global compatibility, predictable yield, and moisture resistance. Match thickness to load, demand BS 1088 or equivalent for critical marine uses, and require FSC or emissions documentation where regulations or customers demand sustainability. When you standardize on this size, your teams cut less waste, install faster, and reduce project risk.
Note: If you need a specification sheet or a sample panel, contact your supplier and request technical test reports that show glue type, formaldehyde emission levels, and face/core veneer species.
