Fire Doors

In our time, all buildings are designed according to the rules and regulations established to prevent fire, how to localize fires, methods of evacuation of people from dangerous areas during a fire. Fire-resistant metal Doors are an integral part of fire barriers that prevent the spread of fire within a specified time. The main purpose of fire doors to stop the fire in one place, avoiding penetration of smoke and its neighboring. Such a metal structure to maintain fire within the time specified in the certificate. Testing of the fire is carried out in special laboratories.

Fire doors should be chosen in such a way that if the office had a fire and will burn it all, the integrity of the door is not disturbed. On average, flat, covered by the elements, burn for 15-20 minutes. Warehouses can be burn longer (due to equipment and synthetic finishes: walls, floors, ceilings, furniture). Hence the conclusion: it is desirable that the fire resistance of doors was at least 30 minutes. These doors are both deaf, and entirely of glass or partly glazed, and they may be single-wing or folding. Fire-resistant glazing can provide effective protection of objects from the fire and smoke to locate fires and prevents the spread flame.

Used glass exhibit excellent transparency, which allows you to install them in administrative, industrial and residential buildings. They are widely used in the construction of doors, windows and translucent walls. Fire protection glazing is divided into several main classes: Class E. The degree of protection from flame and combustion products. Glasses provide protection only for this class Fire resistance can not localize the heat flux in this regard in a protected housing a high probability of ignition of inflammable objects. Class I. The degree of protection from the heat. Glass with high insulating properties. Class EI. The degree of protection from fire, combustion and high temperatures. When installing the glazing of the class provides the highest protection for a specified time. Class W. Degree of protection heat flow. This is a high-melting glass, do not let the heat. Class EW. Protection against flames, heat and combustion products. If you install fire-glazed with the degree of protection for a specified time will be ensured the safety of the building, people and property. The figure comes after a class of fire safety, means the amount of time during which the defense is valid, for example, EI-30 provides protection from fire, gas and high temperature for 30 minutes.

Stretch Ceilings

About stretch ceilings What is a stretch ceiling – a kind of cloth made of elastic soft material to be installed slightly lower than normal ceiling. This product or material can be of several types – vinyl – is made based on polyester fabrics or PVC. Product weight ranges from 100g per m2 to 330 g per m2, the thickness of the applied material from 0,15 mm to 0,25 mm. Its benefit over usual – fast installation and the ability to create complex shapes in different planes or slopes. Ceilings may be different in design, texture and color and, therefore, create endless possibilities of flight concepts designer or an ordinary person.

It is best to create just such a ceiling, which should be fully consistent with the overall composition and meaning of the design project and any housing facilities. Stretch ceilings are available in great variety, texture of the films more than 12 species: satin, moire, a suede, under the skin, mother of pearl, matt, wood, lacquered perforated satin with anti-microbial treatment, metallic, marble and lacquered. And each invoice has razlisnoe of colors. Stretch ceilings can withstand weight up to 100 liters of water per square meter, which undoubtedly shows their strength. Ceilings are assembled in virtually any room, as they almost completely susceptible to moisture and temperature changes – temperature regime they stand can vary from minus fifty to plus fifty degrees Celsius.

Shelving

Versatile shelving is the best suited for warehousing of various weight categories. For them, the inherent versatility, speed and ease of installation, reliability and durability. In all these mentioned, these positive qualities are worth little. Shelving racks are made from cold rolled steel sections, often – galvanized, allowing them to install in any environment, from any temperature warehouses, and that is in unheated buildings. Shelving galvanized steel nadezhnonadezhno protected from destruction. It defines the long-term operation of metal shelving racks.

Since Zinc has a good electrochemical resistance, greater protection of shelving shelving is not reduced even in case of damage, but it happens in every store quite often. Design metal shelving racks easy. They are going out of uprights, cargo beams, metal shelving, decking. All elements of the shelving of this type are connected by bolts. It is important to note that such metal shelving racks can be equipped with other details, such as rods for clothes. Versatile shelving racks are used for cargo medium size and weight. Processing stored on their loads carried by hand. Employees will gladly help you in selecting a suitable design of the whole range of versatile shelving racks.

Universal racks are divided into several types, differing in a variety of modifications. First of all, this archival shelving designed for long storage of various documents, so it is safe to use for backups. Case that the library shelves in fact, too, are archived, however, such universal metal shelving for libraries differ from simply archive their configurations. Versatile shelving shelving type intended to be put in the archives, offices, small warehouses, and any outbuildings. The vast majority of the racks are a versatile shelving racks, making rational use of the space of the room. They are fairly easy to assemble and dismantle, have a great life. Another type of universal shelving racks are a commercial shelving. Trading racks installed in the trading rooms of large stores and shopping less. As with any kind of universal racks, shelving can be assembled trading in many ways to suit the particular room. They are suitable for store a wide range of products. Metal Shelving stands – perhaps the most popular type of shelving used for storage of various industrial products in warehouses, to show them in large supermarkets. They are successfully used in archives, libraries, registries of medical facilities, various locations. Typically, shelving metal shelving hold ready-made, that is one reason a large distribution warehouse in the various fields of activity. Structural elements of these racks are easy to transport. They are designed so that very easily and quickly assembled in racks required height and length with the required number of sections, the distance between the shelves. Latest on the customer's request can be made both of metal and of chipboard or plywood. Modern shelving collapsible shelving type are made so that allow more efficient use of warehouse space, optimize warehouse or other premises where they are used. The advantages of prefabricated shelving racks are clear: simplicity, reliability storage products, compact design, high productivity in the service of a warehouse due to easy access to each section of the rack with the stored products. These racks are dismantled as easily as collected, it can at the right time to make them re-planning.

Sheet Material

Roll – it's a machine that is used for production of cylindrical, conical or oval shape of the sheet material by bending. The raw material is often a metal such as sheet bending rolls are called. The main working parts are Val rolls – cylinders around which molding material is. The number of cylinders can be different – from three to five. The most common three-and chetyrehvalkovye rolls. Roller machine has a radial adjustment for changes in the magnitude of the gap between Val and, depending on the model – the angular and axial adjustment.

Rollers used in the metallurgical industry have on the surface Valkov deepen – gutters or streams for molding a metal profile. In addition, the rolling mills are distinguished – the equipment used in industry for the manufacture of sheet metal. These mills have two Val. Also dvuhvalkovye mills used for grinding of any material, such as food, or rubber industry. Cylinders – Val in the majority of structures are hollow inside, and, depending on the scope the use of specific equipment fitted with cooling or heating. Rollers are different in the drive: mechanical, electromechanical and hydraulic.

Current models of cars have roll machines. Principle rolls of sheet metal roll is as follows: sheet metal, such as steel, iron, zinc or copper enters the gap between rotating in opposite directions and Val run-around top-Val, forming a circular piece – shell. Shell diameter is regulated by moving the two side Valkov relative to the top with a fixed position. There's also the reverse scheme: moving the upper central outrigger and lateral position is fixed. To obtain conical shells is one of the edges of the sheet bend retarded. Various types of molded metal Valkov in hot or cold. Rolling mills are designed to obtain sheet products. Their work is based on multiple hot lamination blanks between Val. As you go through a metal rolling mills and by adjusting the gap between them roll out a sheet gets thinner and longer. Crushing rolls are grooved surface Valkov. Granular raw material enters the gap between oppositely rotating Val, and passing through them, pulverized by compression. Areas of application rollers, the benefits of rolling machines have a wide range of application and are used in many industries. In metallurgy, machine building and equipment are indispensable rolling mills and rolls bending machines. With these machines produce pipes of various diameters, from water with a small cross section to the wide air. Also, the use of rolls made Breather, chimneys, and various housings and containers, the whole ventilation system. Bending rolls are capable of performing many operations: pre-and tapered curves, various deflections, bending and hem. In milling and food processing mills used crushers. Rubber and chemical industry uses several types of rolls: listovalnye, crushing, refining, sheet metal? processing polymeric materials and for the final product of them. Among the bending roller machine rolls on chetyrehvalkovye today have several advantages: a balanced system of adjustment of the leaf reliability, simple operation and high productivity.
