Many assume aluminum-wood doors are heavier because they contain metal. The truth? Solid wood doors are significantly heavier at the same size. This matters when selecting the right door hardware – especially hinges.
Weight Comparison (2.1m × 0.9m standard door)
| Door Type | Core Structure | Approx. Weight | Hinge Load Need |
| Aluminum-Wood (Aluminum honeycomb) | Alu frame + honeycomb | 30–38 kg | Low (≥20 kg/hinge) |
| Aluminum-Wood (Wood core) | Alu frame + wood/LVL | 42–53 kg | Medium (≥30 kg/hinge) |
| Solid Wood (Softwood, e.g., pine) | Solid softwood | 38–47 kg | Medium (≥30 kg/hinge) |
| Solid Wood (Hardwood, e.g., oak) | Solid hardwood | 57–76 kg | High (≥50 kg/hinge) |
Why the Difference?
Aluminum-wood doors use aluminum alloy (density 2.7 g/cm³) for the frame and lightweight aluminum honeycomb filling. They are strong yet light.
Solid hardwood doors (oak, walnut) have density of 0.7–0.9 g/cm³. A 40mm thick oak door (2.1×0.9m) weighs ~57 kg – almost double a honeycomb aluminum-wood door.
Hinge Selection Guide
For solid hardwood doors:
Use 3–4 heavy-duty hinges
Choose EN 1935 Grade 12–14 (100–160 kg test door weight)
Prefer SUS304 stainless steel for coastal/humid areas
For aluminum-wood doors:
3 standard hinges are sufficient
EN 1935 Grade 8–10 works well
Zinc alloy with quality electroplating is fine for indoor use

FAQ
Q1: Which door type is heavier – aluminum-wood or solid wood?
A. Solid wood (especially hardwood) is significantly heavier. A solid oak door can weigh 57–76 kg, while an aluminum honeycomb door weighs only 30–38 kg.
Q2: Can I use the same hinges for both door types?
A. Not recommended. Light aluminum-wood doors work fine with standard hinges. Heavy solid wood doors require higher load capacity hinges (≥50 kg per hinge) and often 4 hinges.
Q3: Does YALIS make hinges for solid hardwood doors?
A. Yes. Our concealed 3D adjustable hinges and heavy-duty ball bearing hinges are rated up to 150 kg, perfect for oak, walnut, or other dense wood doors.
Q4: How many hinges do I need for a 65 kg solid wood door?
A. Use 3 heavy-duty hinges (each rated ≥50 kg) or 4 standard-grade hinges for better weight distribution.
Q5: Are stainless steel hinges necessary for aluminum-wood doors?
A. Only if the door is exposed to coastal or high-humidity conditions. For dry indoor use, quality zinc alloy electroplated hinges are sufficient.
