HDO & MDO Plywood for Formwork & Signage.

Both have a resin-impregnated fibre overlay over a plywood core. MDO is commonly chosen for painted signs and coated panels. HDO has a harder, more resin-rich, lower-absorption surface, commonly selected for smooth concrete formwork and industrial working faces. Share the finish and use you need, and our factory team will help you compare the overlay, core and sample.

No. MDO means Medium Density Overlay: it has a fibre overlay over a cross-laminated plywood core. MDF is a board made from compressed wood fibres. If you need a paintable plywood panel for a sign or coated exterior component, tell us the application, exposure and finishing system so we can help you select the MDO construction.

HDO and MDO have resin-fibre overlays over a plywood core. Phenolic-film-faced plywood has a specified film working face, commonly for concrete forming. HPL plywood has a decorative high-pressure laminate bonded to the substrate for its chosen finish. Select the actual surface construction, grade, core and bond for the application: a decorative HPL face is not a concrete-form grade, and a general MDO paint base is not the same as concrete-form MDO.

Yes. MDO can be supplied unprimed or factory-primed for the agreed coating system. Choose the primer, paint or graphics with the required face preparation, sealed edges and holes, fixings and supports. Test the finish on a sample of the selected panel before production. Tell us whether you need a sign blank, coated panel or machined part when enquiring.

HDO is commonly selected for a smooth concrete finish; a concrete-form MDO construction can be specified for a matte finish. State that the panel is for formwork rather than a general paint base. Reuse depends on the panel construction, supports, release agent, concrete mix, cleaning, edge protection and handling. Discuss your forming method and finish with us; a project trial is more useful than assuming a fixed reuse count.

Yes. Options include an overlaid face with a balanced back, overlays on both faces, or a custom HDO/MDO face/back combination. Tell us which surfaces will be visible, painted or exposed during use. We agree both faces, the finish and any priming in the quotation so the panel matches your fabrication needs.

Options include selected poplar, combi, eucalyptus-hardwood, hardwood and birch-led high-ply constructions. Choose the core and ply arrangement alongside the required machining, dimensions and application. Send your panel use, thickness and budget so we can compare suitable constructions and a sample with you.

Regular sheet sizes: 1220×2440, 1250×2500, 1525×3050 mm. Available on request: 1250×3050, 1250×3660, 2100×2800, 1830×3660, 1250×3800 mm. Thickness options cover 6–30 mm by construction, including 9, 12, 15, 18, 21 and 24/25 mm. For a 3/4 inch MDO plywood order, agree the actual millimetre thickness and tolerance in your quotation rather than assuming it is the same as 18 mm.

Use tooling suited to the overlay and plywood construction, then reseal exposed cuts and drilled holes with a compatible system where the service conditions require it. Agree edge distances, hole positions, cut quality and the intended coating or release agent before machining. Share your drawing if you need factory cutting or CNC work.

Tell us the application, destination and required standard. We confirm the relevant bond, dimensional, emission and surface-test documents for the selected construction, plus any coating trial or project documents needed. For construction use, include required declarations or marking. If you need PS 1 or APA-rated supply, state that explicitly so we can confirm availability. Custom sheet size is a production choice; the certificate or test report’s product scope determines its applicability.

Compare the FOB China prices above and send your specification for a quotation. Overlay, core, face/back arrangement, priming, thickness, machining, tests, quantity, packing and delivery terms affect the price. We confirm the minimum order and available thickness mix for your selected construction. Compare quotations on the same specification and delivery basis, not the overlay name alone.

Yes. Tell us what you are making, the surface you want, the thickness and delivery country. Add your coating, forming or machining requirements if known; we help choose a suitable HDO or MDO sample. We confirm sample availability, sample and courier costs, and dispatch arrangements before proceeding. Use the selected panel to examine the overlay and core and trial your paint or forming finish before placing the production order.

Send the application, sheet sizes, thicknesses, quantity and destination country or port. Add your preferred overlay, priming, machining, product documents and target delivery date when known. You do not need every technical detail ready to enquire: we help complete the specification, then confirm the production schedule, payment, export packing and delivery terms. Production time and transit time are discussed separately.

Yes. CUZI PLY manufactures and supplies HDO and MDO plywood directly from our factory in Linyi, Shandong, China. Our factory has 10 production lines across our plywood range. You can order the selected overlay, core and face/back arrangement as full sheets or agreed processed parts. We confirm quantities by size and thickness, product documents, machining, sample arrangements, packing and delivery terms in your factory quotation.
