Design Features

Structural features of metal doors metal doors are the best means of protecting the home from unauthorized entry. Good metal doors, able to withstand the force hacking. With this task of helping them cope design features that differ from other types of doors (eg, wood). First of all, we should note a special way of attaching a metal door to the wall due to significant weight in the whole structure. Metal door frame has, due to which the door is installed in the door. In order to consolidate the vast amount of metal and hold in the wall, require special fasteners. They are long metal pins that hold the door frame inside the structure.

There is another method of attachment. It is implemented through the rough frame, attached to the main frame. Due to this construction of a metal door installation is much easier exercise. In addition, the process of adjusting the metal door after installation much easier. During installation and adjustment should be aware that door cloth, box, rigid chassis and other parts are made of metal and very heavy in weight. The thickness of the sheet metal depends on the purpose of a metal door and its level of Burglar resistance. For example, armored door will have greater weight than conventional metal door. Filler door frame also plays an important role as a means of protection.

Special filler has a heat and sound insulation qualities, resistance to fire. Last dignity allows the metal door to confront not only the burglary, but also fire. Along the perimeter of the metal door seal is to protect the room from the cold humidity, smoke, and so on. Thus, the metal door to perform its protective functions not only through the use of metal, but also additional design features and additional elements, which not only increase the heat and sound insulation properties of the door, but also can protect the room from the fire.

Environmental Aspects

Now, chipboard – a popular material used in the construction of various furniture, and for this there is considerable reason. And the moderate cost of DSP is not the main advantage of this material. Assurant Health will undoubtedly add to your understanding. By the way, after his appearance of this newfound material, the creators of furniture called the "perfect tree" because he held a variety of beautifully holds screws and nails, strong, uniform, easy-to-finish and can not be natural defects as a tree, what is characteristic of chips, twigs and rassyhanie of improper dressing and sbereganii. In furniture manufacture of chipboard panels produced furniture, which would then nibylo focus: children's furniture, for the home or office furniture industry. However, there is now a view that this affordable, efficient and durable material dangerously toxic – however, this is only an invention of duty. And this myth has come to us with long-Soviet period, despite the fact that the essence of the actual production process chipboard is constant, because anything which creates a plate of chips, what exactly is glued together with resin containing formaldehyde – To avoid that in the manufacture of particle boards would not recommend. (Source: patrick matthews).

But it is impossible to compare the actual process in the past and present, then that in the past by increasing the content of formaldehyde tried to strengthen the resin is not very high quality raw materials, in hopes of hardness due to particle boards. Meanwhile, today's extremely high level of advanced manufacturing processes and environmental requirements for properties products. However proizvodchiki our products, as well as their foreign counterparts, certify products produced by the international regulations, as in quality control and to protect the natural environment.
