Pressure-treated plywood (PT) panel — softwood plywood infused with ACQ preservatives for long-lasting performance in outdoor and ground-contact applications. Resists rot, fungal decay, and insect damage. Ideal for deck substructures, shed floors, exterior sheathing, load-bearing applications, and outdoor structures. Available in standard 4×8 ft sheets.

5/8″ Pressure Treated Plywood is designed for outdoor and construction applications where resistance to rot, decay, insects, and moisture exposure is important. Pressure treated plywood is commonly used for deck components, shed floors, exterior sheathing, subfloors, skids, platforms, utility structures, outdoor storage, and general building projects exposed to harsher conditions. It is a practical choice for contractors, landscapers, builders, and homeowners looking for durable treated plywood sheets for Canadian exterior projects.

 Trustindex verifies that the original source of the review is Google. Picked up a couple sheets of plywood.  Superior quality to big box stores and great prices.  Highly recommend checking them out next time you’ve got a project.

Another gem for a reno project.

Do you deliver across Canada?

Yes - we ship plywood anywhere in Canada from our Ontario warehouse. Most products are in stock locally and ready to go out as soon as your quote is confirmed.

Can I pick up my order in person?

Yes. Pickup is available at our Canadian warehouse and at our US warehouse in Newark, NJ. Let us know during the quote process and we'll arrange a time.

Why aren't prices listed on the site?

Plywood pricing moves with the global market. Supply costs, shipping rates, and exchange rates shift week to week - sometimes 10-15% within a few months. Posting a static price would either be outdated or force us to inflate it as a safety margin. Instead, we send you a personal quote with current pricing, so you pay what it actually costs today.

Do you offer volume discounts?

Yes. We offer discounts on full packages (bundles) of plywood. The number of sheets per package varies by product, so please call us to confirm the pack size, or simply submit a quote request and we'll sort it out for you.

Do you price-match other suppliers?

Send us a quote request with what you're seeing elsewhere and we'll do our best to match or beat it, especially on larger orders. Our pricing is competitive on volume and on premium grades.

Who do you work with?

Anyone who needs plywood. Our customers include DIY hobbyists, cabinetmakers, furniture builders, contractors, CNC and laser shops, and large-scale manufacturers. The same quote process works whether you need one sheet or a hundred.

Can I get a sample before ordering?

For large or recurring orders we can arrange samples on request. Send us a note about your project and we'll work something out.

What types of plywood do you sell?

We carry a range of products for different applications - including cabinet-grade interior plywood, exterior and marine-grade plywood, laser die boards, formwork plywood for concrete pouring, and specialty boards. Browse the Products page to see what's currently available, or send us a quote request describing your project and we'll point you to what fits.

What's the difference between Interior and Exterior plywood?

The glue. Interior plywood typically uses melamine-based glue - strong and stable in dry indoor conditions, but not waterproof. Exterior plywood uses phenolic glue (often labeled WBP - Water Boiled Proof), which holds up to moisture, weather, and outdoor exposure. If your project will see rain, humidity, or any contact with water, choose Exterior. Application is listed on every product page.

How do I know which thickness to choose?

Common rules of thumb for furniture and cabinet work: 1/8" and 1/4" for backing panels, drawer bottoms, model-making, and laser cutting; 1/2" for drawer sides and light shelving; 5/8" for lighter cabinet boxes; 3/4" for cabinet boxes, furniture, structural work, and heavy shelving. Formwork and structural plywood use different thickness logic based on load and span. If you're unsure, describe your project in your quote request - we'll suggest the right thickness.
