Wholesale the Best Solid Wooden Doors for houses OEM & ODM from China 

Wooden doors have been used for thousands of years as one of the most basic building materials for doors. Here is a detailed introduction to wooden doors, including materials, construction, types, advantages, prices, and more.

Materials and construction:
Wooden doors are made from various types of wood such as pine, oak, mahogany, etc. The wood is cut into boards and panels, then assembled through techniques such as mortise and tenon joinery or using metal hinges and frames. The wood can be left in its natural color or painted/lacquered.

Types of wood doors:
– Solid wood doors: Made from a single piece of solid wood, very durable but also heavy and expensive.
– Composite wood doors: Made from wood pieces/fibers bonded together with adhesives, more affordable than solid wood.
– Flush doors: Thin wooden frames filled with wooden blocks/honeycomb paper/fiberboard, lightweight and affordable.

Advantages of wood doors:
– Natural and environmentally friendly material. Wood is renewable.
– Excellent insulation. Wood blocks heat/cold transfer well.
– Durable when made from hardwood and well constructed. Can last for decades with proper maintenance.
– Wide variety of styles to suit any interior decor and architecture.
– Pricing depends on wood type but is generally affordable compared to other materials.

Disadvantages:
– Requires periodic re-painting/lacquering, or they will crack and rot when exposed to elements.
– Not as strong as some synthetic materials when it comes to impacts. Easily dented or broken.
– Natural material so each wood door is unique – may have knots and grain variations.
– Heavier than some other door materials.

Common wood types used and their pricing:
– Pine: The most affordable at $50-100 per door. Softwood is not very durable.
– Oak: Hardwood, very durable. Medium pricing at $150-300 per door.
– Mahogany: Luxurious hardwood. Higher-end pricing, $300-500 per door.

Construction: Wood boards are cut, joined, framed, fitted with hinges and other hardware, painted/lacquered, and trimmed. Production takes 3-7 working days per door, depending on size and complexity.

Painted vs. lacquered doors: Paint provides a protective layer but will chip over time. Lacquered doors have the wood grain enhanced and are more resistant to damage but cost more. Always choose water-based low-VOC paints/lacquers.

Deciding a good wood door: Consider wood type, thickness, joinery/frame quality, and fire rating if needed. Look for intact grain, smooth surfaces, and the right size. Check for signs of warping, cracks, or holes. Hardware should be sturdy.

Best types: Solid core wood or composite/fiber-reinforced styles are the most durable. Hardwoods like oak hold up well with proper care. Flush doors are good for low-traffic areas.

Production process: Wood selection – cutting – joining – framing – sanding – priming – staining/painting – hardware installation – quality checks – packaging.

Benefits: Natural material is environmentally friendly. Wooden doors provide insulation and complement many architectural styles. With maintenance, they can last for decades.

Certifications: FSC\CE\ISO-certified sources ensure the wood is harvested sustainably. Most manufacturers receive low formaldehyde emissions certifications like CARB or EPA TSCA Title VI.

Sizes:
– Standard residential interior doors are 6’8″ or 1980 mm in height.
– Exterior doors often come in thicker slabs and larger widths, up to 3’6″ or 1050 mm.
– Custom sizes are available upon request.

Production capacity:
– A small workshop can produce 50–100 doors per month.
– Medium factories churn out 200–500 doors per month.
– Large industrial plants have capacities of, 500-1500+ doors per day. (WoodDoorSupplier.com)

Fill materials:
– Hollow-core doors contain a honeycomb paper filling for lightness.
– Solid-core doors use wood chips, sawdust, or MDF boards as internal strengthening.
– Fire-rated doors require special non-combustible mineral fillers.

Door hardness:
– Softwoods like pine have low hardness and are easily dented.
– Hardwoods like oak have higher hardness scores of 1000-1800.
– Composite doors gain strength from wood fibers/strands bonded with resin.

Painted vs. lacquered differences:
– Paint provides a flat protective coating, while lacquer enhances the wood grain.
– Lacquer is more durable but requires redcoat every few years, unlike paint.
– Painted doors can be easily refreshed, but lacquered doors need stripping first.

Formaldehyde levels:
– Most manufacturers adhere to strict <0.05ppm formaldehyde emission limits.
– Some eco-friendly brands use formaldehyde-free adhesives and coatings.

Certifications:
– FSC and PEFC certify sustainable forestry practices.
– CARB and EPA certify low VOC levels in coatings & composites.
– Fire ratings – 20, 45, 60 minutes.

– Types of wood joints: Butt joints, mortise-and-tenon joints, dowel joints, and dovetail joints are common. Stronger joints like mortise and tenon last longer.

– Door thickness: Solid wood doors average 1-3/4 inches thick. Thinner doors below 1-3/8 inches aren’t as durable.

– Core materials: Solid wood, wood composite, polystyrene, polyurethane, and honeycomb are used. Solid cores insulate best but are heaviest.

– Framing: Wood stiles and rails form a perimeter frame to hold door slabs or panels. Frames add strength and stability.

– Panels: Flat or raised/embossed panels of wood, composite, or glass are inserted into the frame. Popular styles include four, six, and nine panels.

– Fire rating: Fire-rated doors contain non-combustible materials and intensive bonding. They self-close to prevent fire/smoke spread.

– Finishing: Wood doors are sanded smooth before a base primer and top coats of paint, stain, or lacquer for protection and aesthetics.

– Hardware: Hinges, locks/latches, peepholes, knockers, handles in brass, nickel, chrome, wrought iron. Choose quality, rated sets.

– Molding/trim: Wood or composite jambs, casings, threshold frame, and finish door openings attractively.

– Installation: Doors must be properly hung, fitted, sealed, trimmed, and finished. Improper installation leads to problems.

– Maintenance: Regular cleaning, light sanding, and refinishing protect wood doors from weathering, wear, and moisture damage.

In summary, wooden doors are a versatile yet affordable choice for interior and exterior use when constructed well from suitable wood types. Their natural material offers good insulation and aesthetic appeal suited to traditional and modern designs alike. With proper care, wood doors can stand the test of time.
