In the past two years, in order to understand the market of steel doors, I ran hundreds of building materials decoration markets across the country and met more than 2,000 dealer friends. Therefore, I have a slight insight into the development trend of the steel-wood door market.

At this stage, the steel-wood door is a revolutionary stage. Although the solid wood composite door and the PVC plastic-plastic door in the interior door industry are occupying a large number of steel and wood doors, the demand for the steel and wood door market will increase significantly in the next three to five years. Country Garden and Hongqing Mountain Many real estate companies have already determined that large quantities of steel and wooden doors will be used, which will drive the development of the entire market to new heights.
The steel-wood doors covered with plastic steel doors will be more recognized by consumers than the painted steel doors. Although the prices of painted steel doors are more suitable for consumers, the mature steel-wood doors with well-grown and thick steel plates far surpass those of painted steel doors.
What is the difference between the two?
Cladding steel doors need to introduce advanced production equipment, unique technology and sophisticated technology. Plastic-clad steel plates are deoiled, rust-removed and phosphatized by chemicals, and then subjected to rust-proof paint treatment. Dozens of tons of pressure are molded to form different types of door panels. The three-dimensional effect is strong because mold pressing is required and the quality requirements of the steel plate are high. Requires full material, the use of 0.6cm plate (actual plate thickness of 0.57cm or so), the steel plate is cold rolled plate, otherwise there will be pressure through the phenomenon of pressure explosion. After being plasticized, PVC is natural wood grain, with clear lines, vivid appearance, smooth, delicate and durable products, and more elegant and domineering.
Transfer spray (paint) door, do not need tens of tons of pressure molding, the use of 0.4cm or 0.5cm material, some less than 0.4cm, after spraying paint is very thick, do not need to pass PVC suction Plastic. If it is used for a little longer, the problem of paint fading and falling off will occur. However, the previous period is more novel and bright than the steel-clad steel doors. Painted steel doors are mostly made of rolled plates. Hot rolled plates are manually cleaned after cutting the plates. They are not clean and easy to remove paint.
Structure of steel wood door leaf
Molded steel plate (0.6cm thick plastic coated and 0.4cm thick baking plate) + wood (also known as inner ribs: there are pine finger joints and other materials) + honeycomb paper (sound insulation effect). Love Tiansteel doors pay attention to quality, self-made plastic-clad steel plate, free paint, environmental protection and health; honeycomb paper in the middle of the door leaf adopts 15mm small aperture, thick paper core (heavy 1.1kg/bar), viscous pressure steel plate, pine finger joint, honeycomb paper It is a green and environmentally friendly styrofoam, which does not contain formaldehyde, so the product is not deformed and has good sound insulation and heat insulation. The exclusive use of the door leaf steel plate bending up and down two left and right, door leaf smashing, anti-cracking performance increased five times. There are hundreds of large and small steel door manufacturers in the country, and only a few manufacturers use two bends. The others use only one bending process. The four sides of the door edge seals are steel edge seals, and this process is also only a few manufacturers; there are more than fifty kinds of door patterns, which are complete and complete.

Door frame technology
Many manufacturers' door frames are covered with PVC film by hand. The cost is relatively low, but many technical problems are easy to occur. For example, when the film is filled with air, the air bubbles are not clean. After a certain period of time, many small bubbles appear, affecting the beauty and service life. Now more beautiful and practical frame is the use of ABS frame, steel frame. ABS door frames and steel frames are made of PVC glue on the door frame plate, universal adhesive pressure ABS panels, and steel plate panels. The surface is not only smooth but also waterproof, moisture-proof, insect-proof and mold-proof, but ABS is pressed with dozens of tons of presses. The cost of the box will be 15-20 yuan higher than the PVC box.
It is worth reminding that the PVC laminated door frame is more susceptible to scratches and bumps than the ABS door frame. A waterproof membrane is attached to the back of the Tianmeng box. In the wet environment in the south, the door frame is not easily deformed. However, there are still many manufacturers are doing hollow frames, even with MDF to do the door frame, frame thickness of about 20mm, some also do ABS frame, but do not fold the general frame, which will affect the overall appearance of the door and life. The material of the door frame determines the overall quality of the steel door and the quality of the brand.
On the market, the door covers generally have solid wood lines, wood-plastic lines, and polymer lines. Love Tiansteel doors are mainly used to prevent insects, water, termites, fire-retardant, environmental protection, no radiation, no impurity, nails can be sawed, no Nail eyes, beautiful and easy to install wood plastic line.
Now, steel doors are derived from solid core steel doors and luxury steel doors. However, at present, the technology and materials are not mature, because the middle of the solid core steel door is the particle board, and the middle of the luxury steel doors is the MDF, PVC, and particle board. The effect of MDF on PVC is as simple as anyone who knows how to decorate the building. Steel doors have now developed into steel frames, and there are also new aluminum doors and frames; the door leaf steel also has powder-coated solid-state wood-grained steel plates, plastic-coated stainless steel plates, and aluminum plates instead of steel plates. As the industry develops, I know that I am just an apprentice on the road to the development of the door industry. Some of the content I wrote may be questioned, but I am still willing to work with everyone to fully promote the development of the steel wooden door business.
