The rates of housing construction in our country are increasing every year, which means that the need for materials and components increases in proportion to. The nomenclature of the finished elements necessary for the construction of buildings includes such points as the doors of vestibule, input and interior. The first two positions are presented by special requirements for strength and durability, because instead of wood, metal is increasingly used.
Cheap doors steel
At the cost of any product, the price of raw materials and materials is a significant percentage, and accordingly manufacturers are looking for ways to reduce these indicators. Cheap doors are made from a steel sheet of a small section and without the use of a frame from a profile pipe. To give sufficient stiffness of the design, stamping and spot welding technologies are used. A heater in cheap doors can serve as a filler from cellulose and polystyrene.
Laminated doors – the best option for massive use
To protect the metal from corrosion and to give an attractive appearance on the outer surfaces of the product, polymer film coatings are applied. Laminated doors (on the site) have several advantages over other similar construction structures, primarily because this type of coating is durable and resistant to external influences. Small scratches and damage to such material are almost invisible. For laminated doors, a huge number of textures and colors have been developed that allow you to imitate expensive materials well.
Inexpensive doors – features of production and application
The low cost of the economy class does not mean their low quality and inability to protect the room from the penetration of outsiders into it. Inexpensive doors (more here) are made from steel rental and meet the basic safety requirements, which are presented to protective structures. In particular, the loops are installed so that there is no access to them. The locks of inexpensive doors have not one locking plate, but as a minimum of three, which fix the canvas in different parts of the opening. Such a system practically eliminates the opening of the structure quickly.
Vladislav Nikolaev, a reserve officer, by dismissal from military service, received an apartment in a new building and found that the entrance protection structure even in appearance is not distinguished by high strength. The search for a suitable product brought him to the company "Sd", that carries out its activities in Moscow. As a result, he purchased, a set of a class of economical decent quality and left such a review: "Personnel of the company Tolkoko explained all the advantages and features of the use of products of this type, helped make a choice and organized delivery and installation. The laminated door leaf was pleased with its worthy look and quality. I will definitely recommend the company to all my friends and friends".
