Metal, copper sword 

The roof, made sword is one of the varieties of grooved roof. Metal (copper) saber - is one of the oldest types of roofing materials, surviving to our days in the form which was invented by our ancestors are. Everyone knows who survived more than one generation, and handed down to us with the patina malachite patina, church domes made of copper in the form of an oblique truncated drafts. This kind of coverage rather laborious and requires highly skilled approach.Technology devices roofs of copper pieces handed down from generation to generation, and professionals - tin plate in this area is very hard to find, but their work is highly appreciated. In consequence, the roof made in the form of copper pots, is one of the most expensive options for laying the roof. Benefits of roofing copper pieces that it may perform from the roof of the most intricate configurations, including the finish, radius and spherical surfaces. Metal sword made by the same technology as the copper sword and is an alternative to copper pieces. With the advent of high-quality roofing tin production of polymer-coated metal pieces has increased significantly. Checkers, scales of tin with a polymer coating on all indicators close to the copper checker, but it is much cheaper. Saber made of tin with a polymer coating is usually applied to cover krivoleneynyh surfaces such as domes, turrets, the apse on the roofs covered with standing seam roof or metallocherepichnoy the same color. In recent years, and is often used on flat surfaces, if it fits into the overall architectural appearance of buildings. In terms of appearance - a sword, scales - are small squares or diamonds (less trapezium) with direct lock in the lower part and reverse lock at the top. Connections of each other with proihodit Zatsepa castles and their subsequent sklepyvaniya. Due to the direction of the water "the castle" excludes the possibility of leaks. Scales are different from the drafts so that it is convex, and is shaped like the scales of fish. Hence the name. Standard sizes of scales and pieces 21 cm by 21 cm and 33 cm by 33 cm This is due to the size of the copper sheet or roll. When such a scale consumption of copper in the manufacture of checkers - is minimal. When covering the domes and turrets particularly conical or round consumption of copper increases, since the whole sword is different sizes. Usually in the same row of the dome is used to 16,24 or 32 drafts. With each next size pieces or decreases or increases depending on the diameter of the dome and towers. 

The advantages of using steel or copper pieces and scales instead of copper tiles and soft tile 

• fastening pieces or scales to the roof going on around the perimeter of the details, which excludes the possibility of disruption of drafts of a mighty wind; 
• possible to produce drafts and scale of any shape, any size; 
• to meet the complex curved surfaces; 
• variety of forms and materials: galvanized steel, galvanized steel with polymer coating, copper, aluminum, zinc, titanium, aluzinc;
