YOUR SHEATHING SPECIFICATION

Select sheathing by grade, properties and service conditions.

CUZI PLY manufactures construction plywood in our own factory in Linyi, Shandong, China, with 10 production lines. Tell us your roof, wall or floor use, sizes and thickness, quantity and destination. Share the project specification if available; our factory team helps match the veneer construction, structural grade and documents to the design requirements.

Construction and the strength axis

For plywood sheathing, select the face and core species, veneer lay-up, bond and finished thickness with the required strength and stiffness. Identify the strength axis and the direction of the properties used in your design. A decorative face grade, ply count or density on its own does not specify the structural performance.

Include panel joints, supports, loads, fasteners and exposure in the project specification. Plan roof, wall and floor sheathing or compare plywood and OSB for the same assembly.

Rated Sheathing and Structural I

For a North American specification, name the product standard, performance category, span rating, bond classification and required marking. Structural I (also written Structural 1) is a specific sheathing designation for enhanced cross-panel and racking performance. It is separate from Exposure 1, which describes bond durability.

For an APA-specified order, send the complete required panel identity. We confirm the applicable product reports and authorised marking with your quotation. EN, AS/NZS and PS 1 or PS 2 requirements are not automatic substitutes. Compare North American grades and markings.

Exterior grade and moisture exposure

When requesting exterior, external or outdoor grade plywood, describe the duration of wetting, drying, weather exposure and planned protection. Exposure 1 addresses construction-period moisture rather than permanent exposure. An Exterior bond is intended for more demanding weather or moisture conditions, but does not make wood decay-proof or establish the structural load capacity.

Specify the structural properties, coatings, sealed cuts, drainage and maintenance for the assembly. Discuss bond requirements, preservative treatment or marine and exterior constructions where the use calls for them.

Thickness options cover 7–30 mm according to the selected construction, including 18 mm. Plan coverage, panel joints, strength-axis orientation and support with your project design. Custom dimensions are a manufacturing choice; select the grade, construction and properties for the intended use.

Regular sheet sizes

Use standard formats to plan panel quantities, cutting yield and supported joints.

  • 1220×2440 mm
  • 1250×2500 mm
  • 1525×3050 mm

Made-to-order sheet sizes

Coordinate longer or wider sheets with handling, full-sheet support, pack sizes and loading.

  • 1250×3050 mm
  • 1250×3660 mm
  • 2100×2800 mm
  • 1830×3660 mm
  • 1250×3800 mm
STRUCTURAL APPLICATIONS

Select the panel around your roof, wall or floor assembly.

Match the panel to the complete assembly, not just the sheet thickness.

For roof sheathing, agree the panel grade, support spacing and construction-weather exposure. For walls, include bracing, panel joints and the fixing schedule. For subfloors, consider stiffness, loading and the finished floor system. In each case, the selected panel properties, thickness and installation must match your project design.

SUPPORTED INTERFACE

Panel edge, joint, support and fasteners work as one installed detail.

The project designer completes the selected panel with spans, support centres and a connection schedule.

Supported joints & fixingsCoordinate panel orientation, edge bearing, joints and fasteners with the framing design. Protect panels during storage and construction, and follow the specified support and fixing details.
CUTTING & PANEL EDGES

Order the cut sizes and joint profiles your assembly needs.

Tell us the project use, part dimensions, finished thickness, quantity and destination. Add a panel schedule, edge-profile drawing and specified grade or strength-axis direction if available; our factory team helps confirm the processing against your structural design. We quote the plywood and agreed machining together, including finished dimensions, tolerances and protection.

Cut sheets and openings

Mark the reference edge, orientation, dimensions, openings and hole positions. Coordinate cut-outs with the structural design and framing; a service opening can change the working panel. Include a part label and pack sequence where sheets need to arrive in installation order.

Review cut-to-size sheets and routed and drilled plywood components.

Tongue-and-groove panels

Specify which edges receive the tongue and groove, the profile dimensions, fit and net coverage. Coordinate the joint with supports, panel spacing, fixings and the floor or roof build-up. A tongue-and-groove edge is a joint detail, not a structural grade or a substitute for the design requirements.

Agree a machined joint for fit and handling before repeat production. Keep decorative flooring, non-structural underlayment and the load-bearing subfloor distinct. Review floor-layer requirements.

Cut-edge and surface protection

Tell us the coating, edge sealing, exposure and any preservative or fire treatment required. Include site cuts and drilled holes in the protection plan, and check treatment compatibility with the specified construction and structural properties.

Identify critical tolerances and a machined part for comparison. The quote lists the processing and finishing included; the project specification sets the installed joint, support and fixing details.

PLAN YOUR ORDER

Order the panel your roof, wall or floor design calls for.

Start with the project use, sheet size, thickness mix, quantities and destination. Add the required grade and design specification if known; our factory team helps complete the construction, product documents, packing and delivery details.

Roof sheathing

Include the required panel grade, support spacing, strength-axis direction and construction-weather exposure. Agree sheet layouts, supported joints, panel quantities and pack identification for the roofing stage.

Walls & bracing

List the wall panel grade and thickness with the project’s bracing, joint and fastener requirements. Coordinate sheet formats, openings, cutting details and labels with the installation sequence.

Subfloors

Share the specified grade, thickness, support layout and floor build-up. Identify the required edge or joint detail and surface tolerance, then agree the panel mix, packing and arrival schedule.

For repeat stock orders, list quantities by construction, grade, size and thickness; agree labels and pack counts. For a sample, start with the project use, thickness and delivery country. Add any known grade, face, core, edge or machining preference; our factory team helps choose suitable pieces and confirms availability, any sample and courier costs, and dispatch arrangements. Samples support material selection; project design uses the documented panel properties.

BUYER QUESTIONS

Performance, standards and project use

Clear answers before you order.

What is structural plywood used for?

Structural plywood is specified for load-bearing panel applications such as roof and wall sheathing, subfloors and engineered building components. A structural grade or declared set of mechanical properties helps your designer select the panel for the required loads and support spacing. CUZI PLY manufactures the agreed construction and helps you review the product documents before ordering.

What is the difference between structural and non-structural plywood?

Structural plywood is selected by its grade or declared mechanical properties for load-bearing use. Non-structural plywood is selected for other priorities, such as appearance, machining or interior fit-out. A similar face, thickness or exterior bond does not make the two interchangeable. Tell us the component and project requirements so we can help you compare the right product.

Can I use structural plywood for roof, wall and floor sheathing?

Yes, where the selected grade, panel properties, thickness and service conditions meet the project design. Your designer determines spans, support spacing, orientation and connections; the installer follows that specification. Share the intended assembly and required grade with our factory team before placing your order.

Do you manufacture 18mm structural plywood?

Yes. Thickness options cover 7–30 mm according to the selected construction, including 18 mm. Choose the thickness alongside the required grade, stiffness, loads and support arrangement, rather than by thickness alone. Tell us your project specification and quantity for a factory quotation.

Is structural plywood suitable for exterior or wet conditions?

The bond and panel specification must suit the intended service conditions. An exterior bond addresses glue-line durability; it does not by itself establish load capacity or replace the structural grade. Agree moisture exposure, treatment, edge protection and maintenance alongside the project’s structural requirements.

Which core and veneer construction should I choose?

Pine, eucalyptus, poplar, hardwood, birch and combi constructions are considered against the required grade and panel properties. Species, veneer orientation, ply schedule and bond all form part of the specification. Share your designer’s requirements, surface needs and budget, and we will help you compare the available constructions and a sample.

What regular and custom sheet sizes can you supply?

Regular sheet sizes: 1220×2440, 1250×2500, 1525×3050 mm. Available on request: 1250×3050, 1250×3660, 2100×2800, 1830×3660, 1250×3800 mm. Tell us your thickness, finished tolerances and quantity so we can plan production, full-sheet support, packing and loading.

Which product documents should I request for my project?

Start with the standard and grade your project specifies. Request the relevant mechanical properties, test reports, production-control records and required declarations or marking for the product you are ordering. EN, AS/NZS and North American requirements are not interchangeable. Our team will confirm the available documents and any additional testing with your quotation.

Can I request PS 1 or APA-rated plywood for North America?

Tell us the exact product requirement before ordering. We will confirm whether the required grade, reports and authorised markings are available for the proposed supply. An EN or AS/NZS specification is not automatically a PS 1 or APA-rated product.

How much does structural plywood cost, and what is the minimum order?

Compare the FOB China prices above and send your specification for a quotation. Grade, species, construction, thickness mix, testing, marking, packing and shipping terms affect the price. We confirm the minimum order and available mix for the selected construction; share your size, thickness and quantity schedule so we can quote the same specification.

Can I request a sample before placing an order?

Yes. Tell us the application, thickness and delivery country. Add a required grade, face, core or finish preference if known; our factory team helps choose a suitable sample. We confirm its construction, availability, sample and courier costs, and dispatch arrangements before proceeding. A sample helps you examine the face, core and machining; structural design uses the relevant grade and documented properties.

How do I get a quote and confirm the production schedule?

Send the application, sizes, thicknesses, quantity and destination country or port. Add the required standard, grade, designer’s panel requirements and target delivery date when known. You do not need every technical detail ready to enquire. Our factory team helps complete the specification, then confirms product documents, production timing, payment, packing and delivery terms. Production time and transit time are discussed separately.

Is Structural I plywood the same as Exposure 1 sheathing?

No. Structural I is a sheathing designation for enhanced cross-panel and racking performance. Exposure 1 is a bond-durability classification for construction-period moisture, not permanent weather exposure. Give us the product standard, grade, performance category, span rating and required marking as separate requirements. For an APA-specified order, we confirm the applicable product reports and authorised marking with the quotation.

What should I specify for tongue-and-groove plywood panels?

Send the structural grade and finished thickness with the edge-profile drawing, machined edges, joint fit, overall dimensions and net coverage. Include the support, spacing, fixings, floor or roof build-up and moisture protection required by the design. We quote the panel and requested machining together. A tongue-and-groove joint does not by itself define the panel grade, installed load capacity or complete floor system.

Is 18mm structural plywood the same as a 3/4-inch or 23/32-inch panel?

No. Three quarters of an inch is exactly 19.05mm and 23/32 inch is 18.25625mm. A trade label or performance category is not an exact finished-thickness measurement. Specify the thickness, tolerance and measurement method required for your design and joint profile. Exact 4×8ft is 1219.2×2438.4mm; use the required finished sheet dimensions, net coverage and spacing rather than assuming a metric sheet has identical dimensions.
