Order options for 18mm Concrete Shuttering Plywood
START WITH THE CONCRETE YOU WANT TO FORM
Turn your form layout into a practical panel order.
Need panels for a wall pour, column corners, slab edges or repeated precast work? Send a finish photo, form drawing or an existing part. We help select the core, working face and sheet format, then quote full sheets or factory-prepared parts for the job.
For efficient assembly
Start with the part list and the complete sets you need. Include cutting, drilling, edge sealing and kit labels in the factory order, so your team can identify and assemble the supplied pieces.
Already decided on the face? Go directly to 18mm Black Film Faced Plywood, 18mm Brown Film Faced Plywood or 18mm Logo Shuttering Plywood. Use this page to compare the complete form-panel supply before choosing the surface.
CORE, CONTACT FACE AND WBP BOND
Choose a construction around your finish and site cycle.
| Core | Useful starting point | Compare with your site requirement |
|---|---|---|
| Poplar | Cost-conscious formwork and easier sheet handling | Face finish, film and planned working cycle |
| Combi | General shuttering and repeat component kits | Veneer layup, machining and joint fit |
| Eucalyptus hardwood | Repeated pours and demanding handling | Bond, overlay weight and edge protection |
| Birch | Machined parts and system-formwork panels | Finished dimensions, cut quality and fixing details |
Select the working face
Choose black, brown or red film in 120, 135, 180 or 220 g/m² options. Tell us whether one or both faces will contact concrete. For a custom facing or logo, send the surface reference with the panel requirement.
Match the bond to the exposure
Phenolic WBP and high-melamine WBP adhesive systems are available. Include wet concrete contact, repeated wetting, storage and the reuse plan when we compare the core and film options.
Our 1220 × 2440 × 18mm combi-core loading configuration has 13 plies and weighs about 33.2kg at 620kg/m³. Keep the selected core and size with the handling and shipping plan; the technical data separates the available constructions.
WALLS · COLUMNS · SLABS · PRECAST MOULDS
Order the pieces your form needs.
Panels prepared for the way you build
A finish photo, layout or retained component gives us a useful starting point. Choose sheets for your workshop or factory-cut pieces with the holes, sealed edges and kit labels the site needs.
For replacements, bring the existing face, thickness and fixing detail so the new parts fit the current form.
Exposed walls and architectural faces
Choose the facing around the appearance reference, joint lines and tie layout. A trial with a joint and fixing detail helps establish the surface you want before repeating the panel across the order.
Columns and corners
Work from the clear concrete dimensions, corner coverage and any chamfer or liner. We can prepare matching faces and side panels, then identify replacement parts for later pours.
Slab soffits, edges and infills
Separate broad panels, edge strips and opening surrounds in the schedule. Factory cutting and labels make differently sized parts easier to receive and distribute on site.
Precast moulds and repeat parts
Carry contact geometry, inserts and the accepted film into a repeatable part list. Keep a first working set for checking the cast surface, release and replacement fit.
The formwork design provides pressure, panel direction, supports, ties and fixing details. We supply the facing panels and processed parts around that arrangement, with the material information needed for the chosen configuration.
STANDARD SHEETS AND LARGER CUSTOM FORMATS
Choose the sheet around the panel layout.
Standard sheet sizes are 1220 × 2440, 1250 × 2500, 1200 × 2400 and 1500 × 3000mm. We also produce larger custom formats, including 1525 × 3050mm, and cut sizes for your forms.
View the additional custom sheet formats
| Sheet width | Available lengths |
|---|---|
| 1250mm | 2750, 3000, 3340 and 3660mm |
| 1500mm | 2500mm |
| 1525mm | 2750, 3050, 3340 and 3660mm |
| 1830mm | 3050, 3340 and 3850mm |
| 2150mm | 3050, 3340 and 3850mm |
Send the core and working face with the requested format. For larger panels, include receiving access, lifting and the machine working envelope in the supply plan.
The calibrated-core configuration uses 18mm ±0.35mm finished thickness, ±1.0mm length/width tolerance and 8–12% dispatch moisture content. A tighter joint or accessory fit can be included with the component drawing.
On the 33.2kg combi-sheet loading basis, the estimate is approximately 807 sheets per 40HQ using a 26.8-tonne panel allowance. Final packing includes bundle dimensions, packaging weight and the route's payload limits.
CLEAR CONCRETE SIZE TO FINISHED PANEL SIZE
Get the corner dimensions right before cutting.
For a 600 × 400mm clear rectangle with 2400mm high panels at nominal 18mm, two full-width faces cover two inset sides at square butt joints. Each covering face is 600 + 18 + 18 = 636mm wide; the inset faces are 400mm wide. The nominal outside rectangle is 636 × 436mm.
| Part | Rectangle | Quantity per kit | One-side area for these parts |
|---|---|---|---|
| A · full-width face | 636 × 2400mm | 2 | 3.0528m² |
| B · inset side face | 400 × 2400mm | 2 | 1.9200m² |
Use the actual thickness at the corner
The 18mm ±0.35mm supply band is 17.65–18.35mm. With a fixed 636mm outside width, clear width is 636 − left side thickness − right side thickness. For a fixed 600mm clear width, the covering face follows 600 + left side thickness + right side thickness.
Show the controlling concrete-contact dimension on the drawing and include any liner, seal or chamfer. Check a first assembled set for clear size, outside fit and joint condition, then carry that drawing revision into the production kits.
TWO PART TYPES · TEN COMPLETE KITS
Compare complete kits, not just the number of sheets.
Ten of the four-panel kits above need 20 A faces at 636 × 2400mm and 20 B sides at 400 × 2400mm. With 10mm outside trim, 3mm between parts and the 2400mm dimension along the sheet length, the two formats below produce the same required sets.
Read the worked detail and calculations
| Sheet format | Pattern schedule | Sheets | A / B positions | Purchased area |
|---|---|---|---|---|
| 1220 × 2440mm | 20 sheets of A + B | 20 | 20 / 20 | 59.53600m² |
| 1525 × 3050mm | 5 sheets of A + A; 10 sheets of A + B + B | 15 | 20 / 20 | 69.76875m² |
The larger format uses five fewer sheets but buys 10.23275m² more material in this layout. Include that area and the machining work when comparing the delivered kit price.
See the cutting patterns and material quantities
The 1220 × 2440mm sheet has a 1200 × 2420mm usable rectangle. One A and one B need 1039mm across it. The custom 1525 × 3050mm sheet has 1505 × 3030mm usable space: two A faces need 1275mm; A + B + B needs 1442mm.
| Sheet format | Pattern | Occupied width | A positions | B positions |
|---|---|---|---|---|
| 1220 × 2440mm | A + B | 1039mm | 1 | 1 |
| 1525 × 3050mm | A + A | 1275mm | 2 | 0 |
| 1525 × 3050mm | A + B + B | 1442mm | 1 | 2 |
Five A + A sheets and ten A + B + B sheets provide 20 A and 20 B parts. The forty parts have 49.7280m² of one-side panel area, compared with 59.5360m² or 69.76875m² of purchased sheets. Other part heights or useful offcut requirements can change the preferred layout.
Send the required complete kits and any spare A or B pieces. We can quote the finished part count directly, including cutting, edge treatment, sorting and packing. Keep material direction and finished tolerances with the actual cutting list.
MACHINE THE PART · PROTECT THE EDGES · LABEL THE KIT
Move repeated preparation into our factory.
Read machining and workshop guidance
Cut and machine from one drawing
Identify the contact face, finished edges and hole or recess positions. Include the tie pattern and insert detail so trimming, drilling and routing follow the same reference.
Inspect the first finished part
Check size, squareness, film breakout and cut-core condition with the relevant holes and recesses. Keep that part and drawing revision as the reference for the remaining components.
Include protection after cutting and drilling. New edges, hole walls and recesses need the specified treatment before use; restore it after any later site modification.
Compare panel area, concrete-contact area and edge work for the kit
| Quantity basis | One kit | Ten kits | What it describes |
|---|---|---|---|
| One-side panel area | 4.9728m² | 49.7280m² | All four panel rectangles, including corner overlaps |
| Concrete-contact area | 4.8000m² | 48.0000m² | Four vertical clear faces; no top or bottom |
| Component perimeter | 23.344m | 233.440m | Every outside edge of the four separate rectangles |
| Perimeter-wall area at 18mm | 0.420192m² | 4.201920m² | Component edge walls, excluding holes and recesses |
| Vertical corner lines | 9.600m | 96.000m | Four nominal 2400mm-high junctions; plan the sealing detail and materials with the project drawing |
The one-side panel area includes the corner overlaps. The concrete-contact area covers the four clear vertical faces. Add actual holes and recesses when planning edge treatment and use the coating instructions for material consumption.
We can label parts by assembly, face direction and revision. Put identifying marks on the reverse, edges or packaging as required, keeping the concrete-contact face ready for the planned finish.
CHOOSE A FACE SAMPLE OR A FIRST WORKING SET
See the finish and fit before repeating the order.
Compare the material
A face-and-core piece helps choose film, veneer layup and the cut-edge finish. Include a machined edge or hole where it affects your component.
Try the assembled detail
Use a panel or first set with a representative joint, protected edge and tie hole. Review the cast surface and the panel after stripping under the site's concrete and release process.
Keep the selected sample and drawing revision with the order. When comparing facings, carry the core, dimensions and working process through the comparison so the difference is useful to your next purchase.
RECEIVE THE RIGHT MATERIAL AND COMPLETE SETS
Connect the inspection record to the parts delivered.
| Check | Order reference | Useful record |
|---|---|---|
| Material identity | Core, WBP adhesive, working face and thickness | Construction and batch reference |
| Finished fit | Drawing dimensions, contact datum and corner detail | Individual readings and first-assembly check |
| Face and machining | Selected sample, holes, cut edges and recesses | Photos of the relevant working and fixing zones |
| Protection | Edge and hole treatment after machining | Finished-part checks before packing |
| Kit completeness | A/B quantities, spares and drawing revisions | Pack labels, component counts and loading photos |
Count components by type and revision as well as total quantity. Keep spare pieces separately identified. If an arrival check finds a difference, send the pack reference, part label and a clear reading or photograph so our team can work through it with you.
PRODUCT REPORTS AND SHIPMENT RECORDS
Prepare the documents your purchasing team needs.
Use the technical data, selected sample and order specification together. Our published hardwood reports provide a starting point for the tested configurations; your requested core, facing and project standard help us assemble the relevant document pack.

PRODUCT-SPECIFIC QUESTIONS
Questions about 18mm Concrete Shuttering Plywood
Where should I start when choosing shuttering plywood?
Send what you are casting, the concrete finish you want and any drawing or current part. We help choose the core, contact face and WBP adhesive, then compare sheets or factory-prepared kits.
Which standard and custom sizes are available?
Standard sheets are 1220 × 2440, 1250 × 2500, 1200 × 2400 and 1500 × 3000mm. Custom formats include 1525 × 3050mm and the additional width/length combinations listed on this page. We also cut components to your schedule.
What are the thickness tolerance and sheet weight?
The calibrated-core option is 18mm ±0.35mm. A 1220 × 2440 × 18mm combi sheet with 13 plies weighs about 33.2kg at the 620kg/m³ loading basis. Other cores and formats have their own weights.
How do I choose the core, film and adhesive?
Compare poplar, combi, eucalyptus hardwood and birch around handling, machining and the planned site cycle. Black, brown and red film are available in 120, 135, 180 and 220 g/m² options, with phenolic WBP or high-melamine WBP adhesive systems.
Can you supply complete cut-part kits?
Yes. Send dimensions and quantities by part, working-face direction, holes, edge treatment and assembly groups. We can label complete sets and separate spares, so the receiving team can identify the delivered parts.
How should I size panels at a column corner?
Start with the clear concrete dimensions and the corner arrangement. For a covering face, add the actual thickness of both side panels to the clear width. Keep liners, joint treatment and the contact datum on the drawing, then check a first assembled set.
Will a larger sheet reduce the order cost?
It depends on the completed parts. The ten-kit layout on this page uses fewer 1525 × 3050mm sheets but buys more total material than the 1220 × 2440mm plan. Send the actual part list to compare full-sheet and finished-kit quotations.
Can I try a panel before repeating the order?
Yes. Choose a face-and-core piece, machined component or first working set. For visible concrete, include the intended joint, tie detail and release process, then review the cast finish and panel condition after stripping.
Can you provide reports and shipment inspection records?
We help connect technical data and relevant reports with the chosen core, facing and project standard. Dimensional checks, surface photographs, kit counts and packing records can be planned with the order.
What are the production and delivery arrangements?
Production is arranged to order, normally in 10–15 days. Panels ship by container, with packing and freight terms for the specific order. Our 180-day after-sales warranty applies; send the quantity and destination for a complete quotation.
