Steel-Wood Composite Door: Technical Specifications
1. Material Composition
| Layer | Material | Thickness | Function |
|---|---|---|---|
| Exterior Skin | 0.8–1.2mm galvanized steel | 20–24 gauge | Weather/impact resistance |
| Inner Core | Engineered wood (MDF/HDF) | 25–40mm | Structural stability |
| Insulation | Polyurethane foam/mineral wool | 10–20mm | Thermal/acoustic insulation |
| Interior Veneer | Real wood veneer (oak/walnut) | 0.5–3mm | Aesthetic finish |
2. Key Features
✔ Hybrid Durability: Steel exterior resists dents/rust; wood interior prevents condensation
✔ Fire Rating: Up to 60 minutes (with intumescent core)
✔ Thermal Break: Polyamide barrier reduces U-value to 1.2 W/m²K
✔ Customizable: Over 50 woodgrain powder-coat finishes
3. Manufacturing Process
Steel Fabrication
Laser-cut steel sheets with embossed woodgrain texture
Edge-folded for rigidity (16–18° bend angle)
Core Assembly
CNC-milled wood core with routered lock blocks
PU foam injection (density 40–60kg/m³)
Bonding
High-strength epoxy adhesive (peel strength ≥80N/cm)
Hydraulic pressing (15kg/cm² for 30min)
Finishing
7-stage pretreatment (zinc phosphating)
Matte/gloss powder coating (60–80μm)
Wood veneer lamination (UV-cured acrylic topcoat)
