Exterior Grade Plywood

Sheltered joinery and a panel exposed to repeated rain have different service conditions. Describe wetting, drainage and maintenance access, then select the panel designation and coating system. Include cut edges, holes, joints and the reverse wherever moisture can reach the wood.

If the panel also carries a structural, marine or fire requirement, include it on the same item. Use the structural plywood or marine plywood route for the corresponding project documents; keep the exterior exposure and finishing brief with that construction.

When a marine panel is another candidate, use our marine versus exterior plywood comparison to identify the full product requirement alongside the bond and finished detail.

Give any repeated wetting, standing water, ground contact, marine conditions or unusual chemicals a separate description. Those conditions influence the proposed material, treatment and complete assembly; your inquiry should make them visible from the start.

Agree workshop and installation tasks.

For coated joinery, identify the delivered surface preparation and which faces, edges or holes your team will coat. For site-fitted panels, show cuts and drilling planned after delivery, with the required treatment of newly exposed wood. Keep the installation sequence with the finishing instructions.

For reusable outdoor displays, include the transport, dismantling and storage conditions as well as the installed location. Give replaceable parts their own codes. Review the actual joint, fixing and edge detail so the material comparison follows the service your customer expects.

Compare the complete requirement at one delivered stage.

When reviewing alternatives, keep the specified bond, veneer construction, appearance, machining and finishing scope on the same order line. An exterior bond requirement and a natural-durability or treatment requirement answer different questions. Include both when the service location calls for them.

For an EN-based inquiry, keep the required edition and designation with the drawing. BSI lists EN 636 as a plywood specification; the proposed product documents should identify the requirements being met. Ask separately for the relevant bond method/class and structural information rather than turning a general EN reference into a complete product description.

For a North American project, keep the required panel marking, standard, grade and exposure designation with the offer and documents. Request the offered panel’s matching marking and product documents, with the structural properties and service requirements specified for your assembly.

Send the destination, project standard and required result or class with your document request. Identify the proposed species, lay-up, thickness and panel item so the information follows the quoted construction.

Discuss any required treatment, biological durability, fire classification or performance declaration explicitly. Keep the supplied treatment, finish and installed construction within that document request. Our company certificates support the supplier discussion; project material documents follow the named panel.

Request technical data for the selected panel.

Ask for the proposed species, veneer arrangement, thickness and bond data. Keep test results with the tested construction, and include handling and processing instructions for any treatment.

For structural work, include the designer’s panel requirements and relevant product data. Ask the designer to review any change in thickness, veneer construction, supports or loads before finalising the order.

For coating or overlay proposals, retain the named finish system, preparation and instructions with the exposure brief. Keep emission, reaction-to-fire, biological durability and structural questions separate in the document request where they apply. This makes the quotation easier to compare against the project specification.

1. Share the exposure briefGive the location, required grade, thickness and sample dimensions, with the component drawing and visible-face requirement.
2. Prepare the complete detailCut or route the proposed panel, make the fixing or joint and apply the specified face, reverse and edge finishing process.
3. Keep the selected constructionRecord the sample identity, finish process, agreed trial conditions and observations with the quotation and drawing revision.

Samples are free; you pay courier freight, which is credited in full against your formal order. Tell us which working detail you will trial so we can discuss the sample format around that task.

Trial the operations that expose fresh wood.

Use the proposed full-thickness panel for the routed edge, bolt hole or joint your workshop makes. Record tools, the resulting veneer/core edge, preparation and the complete finish sequence. Include the reverse and the newly cut surfaces in the retained component reference.

Follow the coating supplier’s application and curing instructions for the sample. If the project requires an exposure test, agree the method and test the complete detail alongside your workshop trial.

Specify bundle labels by panel item, grade, construction, dimensions, finish and quantity. Discuss face, corner and edge protection, pack-size limits and how your warehouse will handle the sheets or finished parts.

Keep coated or fabricated components identifiable alongside unfaced sheets in a mixed load. Include storage, processing and installation information for the selected panel and finishing system.

At receipt, match the labels and quantities to the packing list and record pack condition before processing. The panel storage guide helps prepare a receiving record; retain any observations with the relevant bundle and item code.

Keep the finished edge in the receiving record.

Plan supports and separation to protect coated faces and machined edges during delivery. Include bundle dimensions, weights and unloading limits, and follow the panel and finish suppliers’ storage instructions.

At receipt, identify chipped edges, face damage or altered holes with the affected item and pack. Compare the supplied stage and geometry against the retained drawing before further cutting or installation. Keep repairs and any site finishing linked to the proposed material and finish instructions.

Orders start at one container, with mixed loads available. Separate each exterior item by construction, grade, dimensions, finish and quantity. Add the other plywood or MDF items for your workshop while keeping their intended uses and labels distinct.

Regular production guidance is 7–15 days, with transport additional. Confirm the exterior item’s schedule around its construction, finishing and sample requirements. Request FOB with the shipment port or CIF with your destination port and target receiving date.

For repeated parts, retain the drawing revision, face range, layer construction, bond requirement and finishing scope under the same item code. The mixed-panel order schedule helps connect those codes to quantities and bundle labels.

Compare offers at the same receiving stage.

Scroll horizontally to compare all columns.

Keep the same price unit, currency and named delivery point. Show usable component counts, process waste and reserve separately from the net drawing quantity. Compare the cost at the next operation rather than equating a bare-sheet offer with a fully prepared part.

For repeats, retain the construction, finish and installation references with the item code. Identify changes in species, lay-up, bond, treatment, coating or delivered processing before using an earlier component trial as the order reference.

An outdoor display brief includes a visible coated face, routed outline and bolt holes. Start by showing where rain reaches the installed part, how the edges drain and which areas are sheltered.

Keep the required panel/bond classification with the proposed lay-up and thickness. Prepare a representative cut-edge and fixing detail with the complete coating process, including reverse and hole treatment. Review the part against the drawing and any agreed assessment method.

Use the selected construction and finishing reference to organise the repeat-part quantities. Include packing protection for finished faces and edges, installation information and the receiving schedule in the quotation.

Count the perimeter and holes alongside the broad faces.

Consider a planning schedule for 120 rectangular display panels, each 600 × 900 × 18 mm, with four straight 8 mm through-holes. These are requested drawing inputs, not available formats or gauges. The geometry below helps scope finishing work on both faces, all perimeter edges and the cylindrical hole walls.

Scroll horizontally to compare all columns.

Before deducting the small circular openings from the faces, the listed surfaces total about 136.30 m². The net unperforated panel area is 64.80 m²; it is a different quantity from the area of both finished faces. Keep routed profiles, countersinks and other changed geometry on the actual drawing.

Use the calculated surface area with the finish supplier’s coverage, edge-preparation and coat-count instructions to estimate coating needs. Include workshop losses and give exposed edges the specified protection.

Keep the panel description, workmanship and intended exposure in the same record. Use any project-required test method and conditions when commissioning a performance assessment.
