The steel wooden door is made of steel and wood. The periphery of the door is fastened with steel plates, and some steel plates are welded. Door frames are generally decorated with steel sleeves and have no paint on the surface, which is a common indoor door in the family. In this issue, I will introduce you to the guide to the purchase of steel and wooden doors.

1 Basic knowledge of steel wooden doors Classification of steel wooden doors

1. Indoor steel wooden door: it is a series of suite doors for interior decoration. The outer layer is made of steel plate, and the interior is filled with environmental protection materials such as wooden frame and paper shell, and the price is favorable. Because the surface material is different from the security door, it can only be installed indoors to avoid sunlight, so it is called indoor door. The combination of the two is called steel and wood interior door. In addition, when installing the door, it will be equipped with a door cover, so it can also be called a steel-wood indoor suit door.

2. Steel wood armored door: On the basis of steel wood door, it emphasizes its superior protective performance. Usually all-steel structure, using multi-layer steel plates, demolition resistance has specific technical indicators.

Steel-wood door structure

The door leaf of the steel wooden door is made of sub-nodal wood, the wooden frame is made of steel plate, the outside is painted, and the middle is filled with honeycomb paper. It has the characteristics of no deformation, insect resistance and environmental protection. As a whole, the steel wooden door consists of three main parts: door cover, door leaf and door cover line, as well as auxiliary accessories such as door rail, lock installation wood block and wood screw.

Advantages and disadvantages of steel wooden door

Advantages: not easy to deform, not afraid of water, suitable for wet areas such as toilets and kitchens. Various styles and shapes, good moth-proof, moisture-proof, antifouling, heat-resistant, sound-proof and heat-insulating characteristics, are durable products.

Disadvantages: the overall weight is relatively heavy, and the requirements for door covers and hinges are relatively high, whether it is production or installation. Because the steel wooden door does not need topcoat treatment, the paint-free door cover is prone to problems. After the steel wooden door is hit, the facade steel plate will sag, and it is difficult to restore the original state. At the same time, steel wooden doors should avoid direct sunlight.

Generally, the cold-rolled steel plate structure of ordinary steel plate has a wooden structure inside and a steel plate outside, and the fillers are generally wood strips and honeycomb paper cold-rolled steel plates. The door panels are all steel plates, and the fillers are generally fireproof cotton, which is relatively light in weight. No more than 40 kilograms, and the bathroom door used more than 60 kilograms. The entrance door of the kitchen door has low security and high security against theft. There is a "security door certification" issued by the technical defense management department of the Ministry of Public Security. Which good steel wooden door or solid wood composite door does not need painting in terms of workmanship, so the paint pollution is less, formaldehyde-free and pollution-free. It is a healthy and excellent green environmental protection product. Because it is mild and high, not easy to deform and not afraid of water, it is very suitable for use in bathrooms and kitchens.

The solid wood composite door is light in weight and not easy to deform and crack. In addition, it has the characteristics of heat preservation, impact resistance and flame retardant, and the sound insulation effect is basically the same as that of solid wood doors. High-grade solid wood composite doors not only have the characteristics of smooth feel and soft color, but also are very environmentally friendly and durable, but they are more expensive. You can choose according to your own needs.

4 how to choose the style and style of steel wooden door

When choosing a steel wooden door, the first thing to consider is the harmonious combination of the style of the steel wooden door and the style of the living room. If the decoration style is smooth and simple, choose a generous and simple style; Lively and lively, choose light and elegant to match; Classical and comfortable, with heavy and elegant decoration style.

Color matching

The color of the steel wooden door matches the color of the living room. The selection of the wood of the steel wooden door should be consistent with the wood of the living room furniture as far as possible, and it needs to be compared with the color of the wall.

Demonstration quality

Touch the door leaf, frame, panel and corner of the steel wooden door to see if it is smooth and flat, and if it feels pricked.

Look at the surface from the side light, and stand on the side of the steel wooden door to see if there are concave and convex waves on the surface of the door panel. If there is, it may be because the steel plate used is relatively thin.

Surface technology

Sticking film process: a plastic material imitating wood grain is stuck on the surface of steel plate, that is, PVC. Fading or "peeling" will occur, and once scratched by sharp tools, the surface will rust and corrode.

Transfer coating process: after the steel plate is treated with phosphating solution, the floor of the steel plate will be sprayed with plastic, and the wood grain will be transferred to the bottom of the steel plate after heating after the door leaf is baked, which is relatively more stable than the film sticking process.

Door cover quality

The materials of steel wooden door covers are generally divided into multi-layer veneer door covers, MDF door covers, steel door covers and multi-layer UV paint door covers. Brand steel wooden doors are generally produced and sold together, and the quality is also guaranteed. If the indoor air is humid, it is recommended not to buy steel wooden door covers with low moisture-proof performance.

Door cover line

Wood-plastic grain: the surface of wood-plastic material is coated with film or sticker paint, which is easy to foam and powder, affecting the use and beauty of steel wooden doors.

Paint lines of plastic steel: based on high-quality plastic steel, the surface is decorated with transferred wood grain and UV paint, and the effect is also the best.

Plastic-steel grain: This is the plastic-steel material using film sticking technology, which will also cause the product to blister and fall off.

hardware fitting

Every steel wooden door needs to choose the right hardware. The hardware supporting the door can be divided into hinge, door suction and lock. The material of hardware should be alloy or stainless steel, especially stainless steel hinge. The gap between the door leaf and the door frame where the hinge is installed is small and beautiful, and the hinge is not allowed to have joints and dead joints.

Standard thickness

The size of steel wooden door is mainly 800mm* 1980mm, and it can also be produced according to user's requirements. The thickness of the door leaf is not less than 38mm. The thickness of door cover (door frame) shall not be less than 18mm, and the width of door cover shall be determined according to the wall thickness. The net thickness of the steel plate shall not be less than 0.5mm.

Price reference

The price advantage of steel wooden doors stems from the high degree of mechanization and can be produced on a large scale. Affordable and changeable. Generally, the price of steel wooden doors is between 200-400 yuan, and the better one is between 500-700 yuan.

Brand service

Try to choose manufacturers with good brand reputation and go to the formal building materials market to choose big brand products. Product quality and after-sales service are more secure, and by looking at the relevant qualification certification of manufacturers, we can see whether the relevant industry standards are complete and true.

Packaging identification

Look at the product name, implementation standard, factory name, address, quality grade, etc. Marked on the product packaging or attached label. For example, whether the basic content of steel wooden doors is marked completely, and whether there is ghosting or deviation in the color matching of words or patterns.

Composition characteristics of door cover material PVC material with multi-layer veneer door cover is easy to degum and deform in high humidity environment. Dense plate door cover Dense plate sticking is formed by coating or pasting PVC film to absorb water, and then expanding, moldy and deformed steel door cover steel plate. The surface is mostly single-sided lines with transfer painting technology, and the lines are relatively simple. Colorless multilayer UV paint decorative door cover Door cover adopts transfer wood grain, and the surface UV paint decorative technology is full and gorgeous, without deformation or cracking. The recommended brand of moistureproof, heat insulation and wear-resistant industries is Wanjia Wanjia Buyang Spring Xin Duo Xin Duo Fu Xin Fu Sim Yonghe Anruiyi Door Industry Ruiyi vigorously rejoices Dragon Tree Dragon Tree Jinda Door Industry KINGDOM5 Steel Wooden Door Purchase Pay attention to false propaganda.

The brand promotion of steel wooden doors is "100% imported" or "imported brand", but the actual merchants only import a small part, and most of them are produced with domestic materials and technologies. In order to prove the "authenticity" of their imports, merchants can also issue import declaration forms and certificates of origin, and promise to pay 10% for one fake, so that you can believe it.

Pseudo-environmental protection

Add green pigment to the substrate, dye the substrate green, and publicize it. Green substrate is to add green environmental protection factors in the production process or publicize that green products are waterproof than natural substrates. In fact, green and non-green have nothing to do with waterproof and environmental protection.

Pseudo concept

Some manufacturers of steel wooden doors are rumored that "imported boards have long specifications and domestic boards have short specifications". The quality of steel wooden doors depends on the selection and matching of raw materials and the processing accuracy of products. There is no difference in size between imported plates and domestic plates, and there is no difference between imported plates and domestic plates if they are produced according to the same technical requirements mentioned above. The product has nothing to do with the length and width of each board.

High temperature and high humidity maintenance of 6 steel wooden doors

Mainly to prevent high temperature and humidity, because if the humidity in the air is too high, it will lead to rust spots on wooden parts and rust on steel parts. In severe cases, the edge sealing material and facing material of the door body will fall off. However, it is prone to thermal deformation in high temperature environment, so don't put the heating equipment too close during use.

Door panel hardware cleaning

For ordinary stains on the surface, just wipe them with a soft cotton cloth and try to clean them. If it is difficult to clean, you can use a special cleaning agent for the door body to remove stains. Never use acidic or alkaline cleaners. At the same time, organic solvents can not be used, which will destroy the paint layer on the surface of steel wooden doors, leading to fading, discoloration and peeling of surface decoration materials.

Conclusion Nowadays, steel wooden doors are mostly used as indoor doors, but it is not recommended for the whole family to use steel wooden doors. Bedrooms, study rooms and children's rooms can use relatively environmentally friendly wooden doors or solid wood composite doors, which are beautiful and environmentally friendly, but the price is relatively high. And the bathroom, kitchen and other damp places can choose steel wooden doors.
