YOUR WALL DESIGN

T1-11 plywood siding made for your wall and finish.

T1-11 grooved plywood siding combines a timber face with regularly spaced channels for a distinct panelled appearance. CUZI PLY manufactures smooth and rough-sawn options for sheds, agricultural buildings, utility structures and exterior cladding. Tell us the wall use and look you want; our factory team helps you select the face, plywood core, exterior bond, groove profile and finish.

Our siding uses cross-laminated wood veneers. It is plywood, not OSB siding made from wood strands. When replacing existing cladding, match the thickness, groove spacing, face texture and edge joint so the new panels fit the elevation and finish.

Tell us if the siding will be structural or fixed directly to framing, and share your wall specification if available. We help identify the panel construction and documents, then confirm the required product standard, wall design, reports and marking before ordering. Appearance and project performance are agreed together.

Exterior T1-11 plywood siding

A smooth or rough-sawn timber face with a repeated groove pattern, exterior-bonded core and specified edge profile.

Choose the thickness, finish and wall use with our factory team.

Custom grooved wall panels

A drawing-based groove and edge profile for the appearance and dimensions your project needs.

Agree a profile and joint sample alongside the panel construction.

Interior grooved plywood

Decorative grooved panels for selected interior or covered wall linings.

Discuss the face, finish and any required emission or fire-performance documents.

GROOVE SPACING

Choose 4-inch or 8-inch grooves for the look you want.

4 IN OC

101.6 mm on centre

A closer groove pattern with narrower visible strips.

8 IN OC

203.2 mm on centre

A wider groove pattern with broader visible strips.

Four-inch spacing (101.6 mm on centre) creates a closer pattern; eight-inch spacing (203.2 mm on centre) gives broader visible strips. We agree groove width, depth and edge offsets with your drawing or sample so the pattern continues across adjacent sheets.

Groove depth is matched to the plywood thickness and lay-up. A full-width sample lets you check the remaining thickness, groove-base appearance and joint fit before committing to the production order.

SIZES & THICKNESS

Plan panel sizes around the elevation, profile and handling.

Tell us the sheet sizes, thickness and quantities you need for the wall. Share a sheet schedule, panel orientation or joint layout if available. We help coordinate the groove pattern, offsets, finished dimensions and export packing before production.

Agree the finished thickness, measurement condition and groove depth for your construction. Exact 4×8 ft converts to 1219.2×2438.4 mm; the quotation states actual millimetre dimensions and any substitution. Custom sheet dimensions are a manufacturing choice; product documents relate to the construction, profile, thickness and intended use, with any stated dimensional limits.

WALL & INSTALLATION

Plan the siding as part of the complete exterior wall.

Choose square edges or a paired shiplap joint to suit the wall design. With shiplap, complementary rebated edges overlap while maintaining the visible groove pattern. We confirm rebate dimensions, overlap and the finished joint with a two-panel sample. Square-edge installations use the support, gap, flashing, sealant and trim specified for the wall.

Tell us whether the panels will be used as lining, cladding over sheathing or a drainage cavity, or structural siding fixed to framing. Your project design determines the supports, wind loads, fasteners, flashing, clearances and drainage details. We help match the plywood, groove and edge specification to those requirements.

Exterior bonding, a compatible finish and sealed cut edges work alongside the wall’s weather-resistive and drainage layers. If preservative or fire-retardant treatment is needed, include it in the enquiry so we can review the treatment, drying, finish and applicable documents together.

FINISH & CARE

Choose the finish. Protect the profile from factory to site.

T1-11 plywood siding on a timber wall with a weather barrier, drainage battens, supported joints, window flashing and sealed cut edges — **Wall assembly & finish**Coordinate siding with the wall's weather-resistive layers, flashing, supports and fixings. Plan sealed cuts, opening details and the coating system around the intended exposure.

Smooth faces are commonly selected for a primer-and-paint finish. Rough-sawn faces provide a more textured appearance and can be specified with compatible paint or stain. Agree the face sample, factory preparation, coating system and which faces and edges will be finished. Follow the coating instructions for site-cut sealing and touch-up.

We plan dry export packing with full-sheet support and protection for grooves and shiplap edges. Store the panels dry and flat, check the profile and pack condition on arrival, and follow the wall and coating specifications for installation and ongoing maintenance.

MACHINING & FINISH

Order the panel preparation your installation needs.

Cut sizes and groove layout

Start with full-sheet or cut sizes, wall use and quantities. Share a drawing if available; we help complete the groove direction, measurement datum, edge offsets and opening positions so the pattern lines up across the wall. Agree the layout before machining.

Shiplap, openings and drilling

Tell us the joint and openings your wall needs, with an opening or drilling schedule if available. We help agree complementary left and right rebates, overlap and joint fit before machining. Your quotation confirms the supplied operations and tolerances, with a paired joint or machined first part to check fit.

Surface preparation and cut sealing

Tell us the desired wall appearance and whether you want factory preparation or coating. Add a face texture, primer, paint or stain preference if known. We help agree the compatible finish, which faces and edges are treated, and how site cuts will be resealed before production.

Agree machining, finishing, measurement conditions and protected packing with the panel order. We supply the specified siding panels; the supporting wall, drainage, flashing and installation are arranged for your project.

ORDER FOR YOUR WALL

Turn the wall design into a clear factory order.

Buy direct from CUZI PLY, the plywood manufacturer and supplier in Linyi, Shandong, China. Our factory operates 10 plywood production lines. For your T1-11 order, we manufacture the agreed veneer construction, groove profile and edge joint, and arrange the specified finish, inspection and export packing.

Painted sheds and utility walls

Choose a smooth face and shallow groove around your paint finish, panel thickness and supported wall. Check a full-width profile and two-panel joint before agreeing production.

Include in your enquiry: Wall use, look, sizes, thicknesses, quantity and destination. Add face, paint, profile, edge and orientation preferences if known; we help complete the panel details.

Rough-sawn exterior elevations

Plan the timber texture, 4-inch or 8-inch rhythm and joint together. Match panel lengths and groove offsets across the elevation, then agree the coating, cut sealing and profile protection for delivery.

Include in your enquiry: Wall use, desired texture, sizes, thicknesses, quantity and destination. Share elevations, openings, groove or edge preferences, finish and delivery target if available.

Structural or direct-to-framing siding

Use the project’s structural panel and wall specification, including what remains below the grooves. Our factory manufactures the agreed panels and supplies the specified product records; your project team designs the supports, fixing and complete wall.

Include in your enquiry: Wall use, appearance, sizes, thicknesses, quantity and destination, with a project specification if available. Before ordering, confirm the standard and edition, panel grade, profile, supports, wind or load inputs, marking and reports with your project team.

We agree the minimum order and thickness mix, sample and courier costs, profile and finish checks, product documents, packing and payment terms in your quotation. Production time is separate from shipping transit; machining, finishing and any additional testing are included in the agreed production schedule.

BUYER QUESTIONS

T1-11 Plywood Siding

Questions before you order.

What is T1-11 grooved plywood siding used for?

T1-11 grooved plywood siding gives walls a timber-textured panelled appearance, commonly with 4-inch or 8-inch groove spacing. Applications include sheds, agricultural buildings, utility structures and exterior cladding. CUZI PLY manufactures smooth and rough-sawn options with the selected core, exterior bond, groove and edge profile. Tell us your wall design and destination so we can help compare the construction, finish and required product documents.

Should I choose smooth or rough-sawn T1-11 plywood?

Choose a smooth or scratch-sanded face when a clean painted finish is the priority. Rough-sawn pine gives a more pronounced timber texture for painted or stained elevations. Face species, knots, repairs, colour range and coating absorption affect the finished appearance. A face and finishing sample helps you agree the look before placing the production order.

What is the difference between 4-inch and 8-inch groove spacing?

Four-inch spacing is 101.6 mm on centre and creates a closer pattern. Eight-inch spacing is 203.2 mm on centre and gives broader visible strips. Choose the appearance first, then agree groove width, depth, first and last offsets, and pattern continuity at the joint. We can discuss a custom profile from your drawing or sample.

What sheet sizes and thicknesses can I order?

Choose from the regular and on-request sheet formats listed in Sizes & thickness above. Smooth grooved options use 12 or 15 mm, rough-sawn options 15 or 16 mm, and structural project options 15 or 18 mm with the applicable construction and documents. Exact 4×8 ft converts to 1219.2×2438.4 mm; we agree actual millimetre dimensions and tolerances in the order. Custom dimensions are a production choice; product reports relate to the construction, thickness, profile and intended use, with any stated dimensional limits.

Can I order shiplap edges or a custom groove profile?

Yes. Tell us the wall use, look you want and panel dimensions. Add a groove or edge preference, drawing or existing profile if available; we help complete the groove and joint details. A paired shiplap order includes complementary rebates, overlap and the visible joint. Before production, we agree spacing, width, depth and the pattern across adjoining panels with a joint-fit sample, including the remaining plywood thickness below each groove.

Can T1-11 plywood be fixed directly to framing or used structurally?

Tell us whether the panels are structural, fixed directly to framing or decorative cladding over a supporting wall. Share your wall specification if available; we help compare the appropriate construction. For structural or direct-to-framing use, the required standard, support spacing, wind or load requirements, reports, marking and installation conditions are confirmed with your project team before agreeing the order.

How should T1-11 siding be finished and protected outdoors?

Select a compatible primer and paint or stain for the face texture, panel and exposure. Follow the specified coating instructions for grooves, edges, site cuts and touch-up. The complete wall design also addresses weather-resistive layers, drainage where required, supported joints, flashing, clearances and maintenance. Share the exposure and planned finish so we can review panel preparation and any additional treatment requirements.

Can the siding be pressure-treated or fire-retardant?

Include the required preservative use category or fire-performance requirement in your enquiry. We review the panel construction, treatment compatibility, drying, finish and applicable tests or reports for the proposed product. Exterior bond, preservative treatment, structural performance and fire classification are specified for their different purposes. We confirm the selected combination and required documents with your order.

Which certificates and product reports can I request?

Tell us the wall use and destination, with any EN, Australian or North American project specification you already have. We help identify the relevant bond, dimensional, structural, sourcing or finished-product reports and any declarations or markings required for the order. If APA Rated Siding or another named certification is specified, confirm the applicable product and manufacturing scope with our team. Your quotation states which documents are supplied and which additional tests or project confirmations are needed.

Can I request a T1-11 siding sample before ordering?

Yes. Tell us the wall use, look you want, thickness and delivery country. Add face texture, groove spacing, edge or finish preferences if known; our factory helps select the sample. We confirm sample availability, any sample and courier costs, and dispatch arrangements. A full-width profile, cut-edge or paired-joint sample can help you assess appearance, groove depth and fit; a coating sample is useful when the finish is part of the order.

How much does T1-11 plywood siding cost, and what is the minimum order?

Compare the FOB China prices above and send your specification for a quotation. Face species, core, thickness, groove profile, shiplap machining, finish, required testing, quantity and export packing affect the price. We confirm the minimum order and thickness mix for the selected construction. Compare the same panel, profile, product documents and delivery terms; freight and destination charges are included only when stated.

What do you need for a quotation, and how is delivery planned?

Start with the wall use, look you want, sheet size, thickness, quantity and destination. Add face or groove preferences, the planned finish, required standard and target delivery date when known. Our factory helps complete the panel specification, then confirms samples, required documents, production timing, profile protection, export packing, payment and delivery terms in the quotation. Shipping transit time is discussed separately from production lead time.

Is your T1-11 plywood siding the same as OSB siding?

No. CUZI PLY supplies grooved plywood siding made from cross-laminated wood veneers. OSB siding uses a wood-strand substrate and has its own product specification. For replacement panels, compare the actual substrate, thickness, groove spacing, edge joint and coating with the existing wall. For structural use, match the specified grade and product documents as well as the appearance.

Can I order cut-to-size or factory-prepared siding panels?

Send the wall use, desired appearance, panel dimensions and quantities, with a drawing if available. We help complete the groove direction, first and last groove offsets, edge joint and opening or drilling details before machining. Your quotation confirms the supplied operations, tolerances, finishing and cut sealing. Check the full-width profile, paired joint and any machined first part before quantity production. Our supply is the agreed plywood panels; your installation team provides the supporting wall, flashings and fixing system.
