For the choice of board family, compare Hardboard, MDF and HDF by thickness, both faces and fitted use. This page covers the Hardboard specification, cutting and packing you can order.

Identify the face, reverse and assembly direction

A furniture back or drawer bottom has two sides, cut edges and a specific place in the assembly. Choosing Hardboard starts with those details. CUZI MDF manufactures and supplies 1.5–5 mm Hardboard at 810–960 kg/m³ from Shuyang, Jiangsu, China. We connect the selected sheet, visible face, finished dimensions and supported delivery with the part your workshop needs.

The retained product presentation shows brown smooth-face sheets and a patterned reverse. Treat the actual sample as the face reference for the order. Identify Face A and Face B, photograph both under suitable lighting, and keep the sample ID with the board specification. A screen-pattern reverse, smooth reverse or supplied surface finish is described for the particular product. The quote and sample define which construction arrives at your factory.

Identify the face, reverse and assembly direction
Side or referenceWhat your specification identifiesWhat stays with the part record
Face ASelected visible side; raw, coated or another agreed supplied finishAppearance sample, finishing stage and installed orientation
Face B / reverseActual reverse texture and any specified treatmentReverse photograph and contact-face process reference
Top/reference edgeThe same physical edge on drawings and labelsPart ID, datum and orientation for cutting and fitting
Cut edges and openingsPreparation, dimensions and any required finishingEdge/hole sample and the corresponding drawing revision

For a cabinet back, the intended visible side may face the cabinet interior or the accessible rear, depending on the design. A drawer bottom has an upper contents-contact side and a lower side facing its supports. State those installed directions explicitly. Mark the top/reference edge where orientation matters and carry it through the cut list, part label and assembly sample. The drawing's face designation and the delivered part then describe the same component.

Looking from the reverse changes the view of a feature's position. Define the drawing face and datums first, then relate any opposite-face operation to those same physical references. A hole pattern or asymmetric corner detail needs its own view and dimensions. Our schematic retains one datum on the same physical corner, which appears on opposite sides when the component is viewed from Face A and Face B.

The actual Hardboard process, grade, treatment and surface condition belong in the product record. Commercial terms such as smooth one-side describe a surface arrangement. Coating, printing or bonding trials identify the particular contact face and preparation. Density describes mass per volume; the finish and relevant product or assembly tests establish their respective properties. The Hardboard, MDF and HDF comparison guide organizes these material choices around the actual supplied product.

Bring the sheet format and finished cut list into one order

Full-sheet formats for Hardboard follow their own supply information. Send the full size your cutting line needs, or send the required component list and quantities. We record the Hardboard input format, thickness, density, supplied faces and cutting scope in the quotation. The Raw MDF catalogue describes its separate board formats; each product uses the dimensions agreed for its own supply.

Keep three dimension records distinct: the full input sheet, the cut component and the completed fitted part. The cutting plan connects sheet length/width, edge trims, cutting loss, component layout and quantity per part. Facing, coating or final preparation may affect finished thickness and the groove fit. Specify where each dimension is checked and the stage at which the component is supplied.

Bring the sheet format and finished cut list into one order

Cut componentPart ID, finished length × width, face and quantityCut-list revision, operations and assigned tolerances
Completed fitCore/finish thickness, groove or rebate and supportDimension basis, sample checks and supplied finishing stage

A measured replacement back is a useful starting sample. Include the carcass opening, groove or rebate, fixing layout and the original orientation as well as the loose panel. The assembled furniture can show where engagement, squareness or installation sequence affects the selected dimensions. For repeat supply, retain the chosen component and current cut list with the part ID, making replacement orders easier to identify.

The current 1.5–5 mm range identifies the Hardboard product. Exact ordered thickness, format, tolerance and measuring method are recorded for that specification. Core thickness, finished thickness, outside dimensions, squareness, hole position and flatness each have their own measurement agreement. A nominal MDF tolerance from another page applies to its own stated material; Hardboard checks follow the Hardboard order and actual component fit.

For mixed component sets, give quantities by part and face along with the overall sheet count. Add pack sequence or replacement labels where useful to the receiving team. A cutting or component quotation identifies its material, preparation and finish scope. Our furniture components application describes the part-list approach, while your Hardboard request keeps its own product construction and formats.

Choose thickness with the groove, support and finished fit

A supported cabinet back or drawer bottom is part of the complete furniture design. Identify whether its edges fit into grooves, sit in rebates or form an applied back, and show the actual frame or supporting members. Component thickness, engagement, fixing and service loading are chosen together. A representative fitted part gives your team a useful check before the full cutting batch.

As a nominal size example, consider an opening of 586 × 386 mm with an 8 mm groove on each opposite edge. The distance between opposite groove roots is 602 × 402 mm. Choosing a total 2 mm allowance in each direction gives a 600 × 400 mm component. With the panel centred, that geometry leaves a nominal 1 mm root clearance and 7 mm engagement at each edge. These are stated design inputs and calculations; actual assembly dimensions, movement allowances, insertion sequence and permitted loading follow the component design and trial.

Choose thickness with the groove, support and finished fit
Example dimensionStated input or calculationWhat the actual assembly checks
Clear opening586 × 386 mmCarcass/frame dimensions and squareness
Groove depth8 mm at each opposite edgeActual profile, root shape and insertion access
Root-to-root span586 + 8 + 8 = 602 mm; 386 + 8 + 8 = 402 mmMeasured spans at the specified positions
Selected cut part602 − 2 = 600 mm; 402 − 2 = 400 mmFit with the design's total size allowance
Thickness fit3 + 0.10 + 0.05 = 3.15 mm; 3.50 − 3.15 = 0.35 mmFinished thickness, groove width and agreed clearance

The thickness row uses an illustrative 3 mm core, 0.10 mm Face A layer and 0.05 mm Face B layer. Their nominal combined thickness is 3.15 mm. A 3.50 mm groove leaves 0.35 mm total thickness clearance. The layers are example inputs, with actual materials and preparation recorded for the finish. Groove width and core/finished thickness tolerances, surface texture, conditioning and assembly requirements establish the actual fit. The calculation describes geometry and its measuring basis.

For a captured drawer bottom, include unsupported spans, edge engagement, intermediate supports, fixing and the intended contents. Distributed contents and concentrated loads give the assembled bottom different demands. An applied or rebated back uses its actual perimeter support, overlap and fixing positions. Thickness and density are material inputs; the complete assembly's relevant testing or design establishes the working use.

Our Hardboard backs and drawer-bottom application develops the supported-component selection. Thin MDF Board and HDF are separate material options with their own thickness/density schedules. When substituting a board, compare the actual faces, finish, supported construction and part trial alongside the dimensions. The selected product and fitted sample stay with the order.

Prepare cutting, fastening and surface work on the actual sample

Use a representative sample of the ordered Hardboard for cutting and finishing trials. Record both faces, thickness, density, supplied condition and the component drawing. Keep thin sheets supported during cutting, drilling, punching and transfer, with suitable tooling, workholding and extraction for the actual operation. Inspect outside sizes, squareness, edge quality, hole entry/exit and narrow features on the first part.

Define through holes, cut-outs, edge details and any asymmetric feature from the stated face and datums. Assign tolerances to fit-critical dimensions and identify the measurement stage. A reverse-side operation uses a corresponding view of the same physical references. Agree face marking and pack labels so a repeated cut list keeps the intended side and orientation. Large backs and small bottoms can need different support during handling.

Select nails, staples, screws, clips or another connection with the furniture design and fitting guidance. Show fixing positions, edge/corner distances, penetration and the actual supporting frame. A screw passing through a thin back into the frame has its holding engagement in that supporting material; a connection relying on the Hardboard itself has its own fastening and relevant test requirements. Try the actual fastener and assembly, recording fit, appearance and the required connection result.

For coating, printing or lamination, identify the actual contact face, preparation, adhesive or coating system, pressing/curing process and reverse treatment. Surface appearance and process compatibility are separate checks. A patterned reverse receives its own preparation and bond trial when it is used as a contact face. Agree edge finishing and treatment of holes or new cuts with the final component specification.

Raw, coated and faced supply each describe a different finishing stage. The quote lists the operations we supply and the stages completed in your workshop. Retain the finished sample and process reference for repeat batches. A flat furniture skin or infill also follows its complete frame/core, bonding, faces and edge construction; any fire, acoustic or other classified performance uses the relevant complete-product documents and scope.

The European Panel Federation's technical directory separates hardboard product requirements and methods for dimensions, density, bending, internal bond and moisture-related properties. Agree the applicable current method and required values for your selected product. Actual process, grade/treatment, emission information and test scope are specified for the quoted Hardboard family and construction.

Calculate component weight and plan flat-supported packs

Nominal bare-component mass in kg equals length × width × thickness in metres × density in kg/m³. The 600 × 400 × 3 mm example has a volume of 0.6 × 0.4 × 0.003 = 0.00072 m³. At 810–960 kg/m³, its calculated bare mass is 0.5832–0.6912 kg, rounded to 0.58–0.69 kg. The dimensions describe an illustrative cut part, with full-sheet supply separately specified in the quote.

The table keeps the same 600 × 400 mm geometry and 810–960 kg/m³ inputs while changing nominal thickness. Each value is a calculation, with actual thickness/density and any thickness-specific target established for the ordered product. Component strength, support and permissible loading follow the relevant component assessment. The table helps describe mass and handling inputs.

Calculate component weight and plan flat-supported packs
Nominal thickness for the exampleNominal volume, m³Calculated bare-component mass, kg
2 mm0.000480.39–0.46
3 mm0.000720.58–0.69
4 mm0.000960.78–0.92
5 mm0.001200.97–1.15

An illustrative stack of 100 of those bare 3 mm parts calculates to 58.32–69.12 kg before finish and packaging. The pack count is an example input. Actual component mass includes the relevant coatings, facing, hardware and any removed material; gross pack mass adds covers, support, pallet/bearers, wrapping, straps and other packing. Record sheets, parts, cubic metres and net/gross mass as their respective quantities.

Keep thin Hardboard flat with even, suitable support in dry covered storage. Support sheets and cut parts through lifting and line-side movement, and condition material for the workshop process. Clean contact materials, suitable cover boards, separators and protected corners/edges help preserve the selected surfaces. Strap pressure, bearer/pallet layout, stack height and unloading access are agreed for the actual format and equipment.

Pack labels can identify product, thickness, part ID, drawing revision, Face A/top direction where relevant and quantity. The receiving team can then relate the count and visible condition to the correct cut list and sample. Confirm actual gross weights, pack dimensions and handling arrangements in the shipment information. Container loading quantity follows the real dimensions, density, packing and shipping plan.

Turn the fitted sample into a repeat-order reference

Connect the selected product record and first part before repeat cutting. Keep the Hardboard grade/process description, actual Face A/B photographs, core and completed thickness, density, input format, component dimensions and cut-list revision. Add measurement positions, conditioning, actual groove/rebate profile, fixing/support and the observed fitted result. A representative assembled sample covers the part's fit, finish and intended use together.

Inspect a sample set that covers the important dimensions, face conditions, cut edges and assembly details. Compare the actual result with its assigned tolerances and finish reference, then record agreed changes in the current drawing and quotation. Third-party inspection is supported with the scope and timing agreed for the order. Quantity, labelling, sample dimensions, surface/edge condition and flat-supported packing are checked before dispatch; the pre-shipment checklist helps organize that handover.

All product samples can be requested free of charge and are generally in stock. The buyer pays the courier cost, which can be credited against a formal order. Send the Hardboard thickness, faces, finish and delivery address; we confirm availability, dispatch, courier cost and estimated transit time.

Buyer FAQ

Your Hardboard questions, answered.

Is hardboard the same as thin MDF or HDF?

Hardboard, Thin MDF and HDF are separate product constructions. Compare the specified thickness, density, actual face/reverse and processing requirements. A sample in your furniture assembly helps qualify a replacement material.

Which hardboard face should be visible?

Use the specified smooth face for the visible side when that is the chosen construction. Identify any screen-pattern reverse on drawings and labels. For coating or laminating, trial the actual contact face and process for each side used.

Can the standard MDF board sizes be ordered for hardboard?

Hardboard formats are confirmed separately for the ordered sheet. Send your required full-sheet size or finished component list, quantities and cutting plan so the quote records the actual Hardboard format.

How should hardboard drawer bottoms be specified?

State finished dimensions, thickness, groove or rebate fit, support, face orientation and intended drawer contents. Check the actual component in the complete drawer against the design and applicable assembly tests.

How can I request a sample and confirm the cost?

Samples are free and usually in stock. You pay the courier charge, which can be credited against your order. Send the sample details and delivery address for availability, courier cost and timing. We will also give you a preparation date for custom samples.

How is a grooved back size calculated?

Use the measured clear opening, groove depths, total size allowance and assembly requirements. In the nominal example, 586 × 386 mm with 8 mm grooves on each opposite edge gives a 602 × 402 mm root span. A stated 2 mm total allowance per direction gives 600 × 400 mm. Centred geometry gives 7 mm engagement and 1 mm root clearance per edge; actual fit and support follow the design and trial.

How much does a 600 × 400 × 3 mm Hardboard part weigh?

Its nominal bare volume is 0.00072 m³. At 810–960 kg/m³ the calculated mass is 0.5832–0.6912 kg, rounded to 0.58–0.69 kg. An illustrative 100-part bare stack is 58.32–69.12 kg. These are cut-component calculations; actual finish, removed material, packing and measured product values determine the corresponding actual net or gross mass.

What documents describe grade, emissions or special use?

Request the actual Hardboard process/grade/treatment description, dimensions/density records and applicable test reports for your destination and component. Moisture, fire, flooring or structural requests follow their specified product or full assembly construction and relevant scope. Standard supply on this page serves supported furniture parts in protected interiors.
