More and more people from the copper door to the cast aluminum door, cast aluminum door by virtue of its own advantages are favored by people,  what advantage does cast aluminum door have? Today, W & H door manufacturers for everyone under the detailed introduction.

1, 50 years without rust. Don't need surface maintenance, living in humid, high acid and alkali salt content of the air will not rust.

2, Hard: the hardness of aluminum can withstand tension and greater impact

3, corrosion resistance: the surface attached tightly to a layer of hard aluminum oxide coating, and then after the paint or powder surface treatment, can further strengthen its protective properties, it has a strong corrosion resistance, so regardless of air pollution of the city or sea salt c..

Stainless steel doors are made of various kinds of materials, and normally are 304/304L/316/316L/321/310S  410/420/420J1/420J2/430/    201/202

How to identify the quality of different types of stainless steel doors materials is not determined by an individual, but has to be analyzed through chemical methods.

Such as the identification of 400 and 300 series can be done by magnetic method, 400 series material is generally magnetic but 300 series is not. Also 301 series has good ductility which can be used in finished products. This series material can also be rapidly hardened by machining, So it's weldability, abrasion resistance and fatigue strength is better than 304 series materials.

Model 302 has the same corrosion resistance as 304 serie.. Read More

Stainless steel anti-theft door market is not mature enough at the moment, the quality of the each brand is uneven, consumers must pay attention to the five indicators in the process of the purchase.

1, Certificate: production enterprises must have a certificate issued by the statutory inspection where the provincial public security department (bureau) is.

2, Security level: the security level of stainless steel door is divided into A, B, C3 level. C level of anti-theft performance is the highest, B level followed,  a is minimum, doors in the market  are almost a class, generally applicable to the general family. A-level requirements: full steel, flat open all closed, the ordinary mechanical hand tools and portable electric tools interacts, the weakest link can resist.. Read More

1, From the view of funciton

During the house decoration, it seems that common hardware parts could usually cause heavy potential safety hazard, that why we need put the hardware parts such as the locks in a important position.

Frist, Anti theft function: in order to ensure safety of life and property, basic anti theft function of locks is needed in door of master room, study room and especially entrance doors. For now, it is beyond doubt that intelligent lock is more secure. On the other hand, the development of smart home could be imporved to a very large extent as long as the wide use of intelligent locks.

Second, Fire prevention: the function of the design, can avoide sudden event which bring hidden dangers. If the lock is not fire prevention, it will cause deformation in the high temperature of the lock body, which causing danger that the door can not be o.. Read More

The sliding door is used with very high frequency, which can be used as a cabinet door, decoration materials. The noise of sliding door is relatively small, it is not so hard to open, so it is quite appropriate for these families that have old people. Although, sliding door is very convenient to use, but it is also need to be maintained, so let's discuss the way of the cleaning and maintenance of sliding door.

1. Maintenance method of pulley

The pulley is the inner soul for the door, it was small but plays the major role. Every half a year or so, one or two drops of lubricating oil can keep its smooth. Sliding door pulley is divided into an upper and a lower whorl. For brand pulley, lower whorl with needle roller bearings, no need to add lubricating oil, just need to clean debris. General bearings or rubber wheels need to be added with lubrication oil in the sliding pa.. Read More

Decoration which is not environmental protection, unhealthy indoor environment and polluted decoration could do harm to people's health. And in recent years, such as formaldehyde, formaldehyde of leukemia in each big news media, the newspaper reported, has aroused extensive attention of people from all walks of life. So formaldehyde is so terrible, why decoration can not do without it? It is necessary for us to understand.

Extensive use of formaldehyde

Formaldehyde is is the backbone of the downstream products of methanol which has a wide range of USES, simple production process, raw material supply sufficient mass chemical products. World output is 25 million tons, 30% methanol is used for production of formaldehyde. But formaldehyde is a kind of low concentration aqueous solution, from the economic point of view, it is not convenient to transport over long distances,.. Read More

Solid Wood Door: Solid wood door is the door that made of of the whole solid wood. Most popular solid materials generally include: elm, pine, TRAMO, Catalpa wood, ash, beech etc. Characteristics of these doors are clear wood texture, strong overall sense and three-dimensional sense. Prices varies according to the different materials. But its biggest weakness is easy to deform and crack, which is caused by the characteristics of the wood itself. At present, the most advanced technology in the world can not completely resolve the problem.

Composite Door: this type of door made through the hot or cold pressure or by hand to make a variety of materials together. The internal quality of the composite door is not the .. Read More

Polyurethane foam is a kind of material that we use it for anti blocking or sealing on doors. What exactly the physical properties of polyurethane foam that are benifient for us? Here, let's discuess together.

Advantages: light weight, strong hardness, heat insulation, sound insulation, Flame retardant, cold-resistant, anticorrosive, Does not absorb water and also easy for construction.

Small thermal coefficient: The thermal conductivity of polyurethane foam is the lowest in the thermal insulation material which is

Which is much lower than other commonly used pipe insulation material in the past.

Waterproof, anti-corrosion, anti-aging: The obturator rate o.. Read More

Door is the first impression of a family for other people before they enter the house.

But if you pay more attention to the collo.. Read More

Covered by a layer of passivation film of good corrosion resistance, stainless steel door can be isolated from the oxygen from the air in order to prevent rust. Because of different materials, improper protection may affect the appearance of stainless steel doors during the using process. So we need to learn the knowledge of maintenance:

1. Opening and closing process should be slow during the using, in order to prevent damage phenomenon caused by collision between sharp things and stainless steel door protection layer.

2. In general, humid environment is filled with acid gas, so we should pay attention to the damage status caused by oxides and microorganisms on the stainless steel door.

3. For cleanning, we need to choose some agents which don't contain corrosive chemical c.. Read More
