Two melamine faced panels with identical decor can differ by more than 40% in structural performance. The difference is the core. This guide explains the core types available in export production, what each one is suited to, and the bonding classes that should accompany them.
| Core | Density | Screw Holding | Moisture Behaviour | Typical Use |
|---|---|---|---|---|
| Poplar | Low to medium | Moderate | Fair | Interior furniture, dry cabinets, packaging-grade panels |
| Eucalyptus | Medium | Good | Good | Kitchen and bathroom cabinets, humid climates |
| Birch | High | Very good | Very good | Load-bearing shelves, heavy cabinets, commercial fit-out |
| Hardwood / mixed | Medium to high | Good | Good | General furniture and joinery |
| Thickness | Common Application |
|---|---|
| 5.5 mm | Back panels, drawer bottoms |
| 9 mm | Back panels, light shelving |
| 12 mm | Drawer boxes, dividers |
| 15 / 16 mm | Light carcass work |
| 18 mm | Standard cabinet and wardrobe carcass |
| 25 mm | Counter structures, worktops, heavy-duty fit-out |
Export documentation normally distinguishes face grade (the visible decorated side), back grade (the concealed side, sometimes a lower decoration or an uncoated face), and core grade. A panel described as "double-faced" carries melamine on both sides; a "single-face" panel is decorated on one side only and is used where one face is never seen. The distinction affects price significantly and should always be stated in the quotation.
For dry interior furniture at the lowest cost, a poplar core with interior bonding is adequate. For kitchens, bathrooms and any market with high ambient humidity, move up to a eucalyptus or hardwood core with moisture resistant bonding — this is the single most effective upgrade in the specification. For shelves carrying heavy loads, or for commercial and retail fit-out, a denser birch or high-density hardwood core is the appropriate base. Matching the core to the service condition prevents both over-specification and premature failure.
Eucalyptus or hardwood cores with moisture resistant bonding are the practical choice; birch is used where higher strength is also needed.
Significantly. The core and bonding class are usually the largest cost variables after thickness.
Melamine decoration is applied to both sides of the panel. Single-face panels are decorated on one side only.
Only in dry, lightly loaded positions. Under sinks and around appliances, specify a denser core with moisture resistant bonding.
Send your application and climate conditions; we will recommend core, bonding class and thickness and confirm availability for your order.
