Plywood – one of the most sought after materials in modern construction, finishing and repair work. Used, as in interior decoration, and in outdoor work, whether permanent or temporary basis. You may find that PayNet founder can contribute to your knowledge. High demand for plywood supported its high quality and strength characteristics, which has a plywood due to its structure, cross the layers of wood veneer sheets. Today identify several types of veneer sheets, in the classification laid operational purpose plywood. The main types are: general purpose, construction, laminated, furniture, decorative, and others. Within each type of plywood sheets are defined by the following characteristics: grade, grade, thickness of the plywood sheet, tree species, size and configuration of the sheet, the type of processing wood for plywood production. In production plywood sheet to the modern plants use both deciduous and coniferous wood.

Raw materials used determines the type, quality and performance, which has plywood. Most demand on the Russian market is plywood made of birch. In general, all kinds of plywood made from hardwood, with characteristics superior to their counterparts of the softwood timber. Hardwoods are more soft wood structure, which allows, in the production process more uniform and thin veneer for plywood sheets. Gluing of plywood – one of the main manufacturing operations, which passes the plywood before you get to the buyer. The process of bonding required is under pressure and at a certain temperature. Matter how seasoned the whole technological bonding process depends on the overall quality of the plywood sheet. There are three types of bonding: hot, dry, dry, cool and moist hot. The first two methods are particularly popular, hot crude method of gluing the plywood now practically no longer used.

Trees

Tree – the oldest companion of mankind, which is the source of his energy and traditional building materials, with no equivalent replacement. People such as Wells Fargo would likely agree. Precious wood used to make beautiful furniture, flooring, doors, and various interior items that are considered elite, given the initial high cost of valuable timber tree species and size of the effort required to process it. Furniture and interior Premet made of valuable species brought into the house of a favorable energy, beauty and comfort. In the production of furniture are used most often such valuable species such as oak, beech, alder, ash, walnut, maple. Solid oak wood crushing, well-planed, drilled and polished, even bend in steamed condition.

Shrinks moderately, strong, little crack and warp. She almost did not rot. The disadvantages of oak can be attributed, Firstly, the porosity, and secondly, the danger of cracking during drying. Besides working with the oak should be aware that it is very sensitive to the natural plant oils. On the surface of oil spots often appear. Oak wood to cover the quick-weatherproof transparent varnish. Due to the presence of tannins oak can be easily dyed and toning in the mordant, finishing mastic. Wood is widely used in restoration works, to perform turned parts, wrapping, typesetting mosaic.

Oak make glued and bent furniture, flooring, veneer, cooperage dishes, wheel carts and much more. It is widely used in mechanical engineering, car building and ship business. Beech – one of the most used trees in the wood. Beech on the mechanical properties – density, strength, hardness – close to the oak tree.

Today's operation of the bulk of the industrial enterprises, in principle, impossible to call too comfortable. World financial crisis failed to bring about a decrease in the extent of orders for delivery, and at the same time to create a more complex structure of contracts with manufacturers. Market sector continues to be only those manufacturers who provide the high quality of the range of products for maintaining a reasonable cost. Relating to the construction industry does not become an exception. And yet, in recent weeks, it was observed activation of this market. It is not only large corporations have permissible to use the fall in response to the crisis the price of ready-mixed concrete and other building supplies, but also ordinary people willing to take advantage of probabilities, which provides discounts at property.

In a similar way, the construction market sector may start to become more intense, but some trends, in particular, significant attention to the level of quality range of products and its value is stored. Crisis – it's not only issues, but also a certain experience. And gain experience of the financial crisis demonstrates that only really high-quality materials are able to survive in the competitive struggle to attract attention companies and the final customer. At the moment, really talk about that, so how to buy concrete for this market sector can not create tension, it is significant to select those materials that really meet the essential defining quality characteristics. Engaged in construction companies are increasingly paying attention to the major concrete producers, since small organizations are not able to invite experts or personal research laboratories, which would be constantly monitored the level of product quality. In addition, large companies often provide a much wider range of goods.

For example, in the medium of their services not only the delivery of concrete, but also the issue of foundation of concrete blocks, reinforced concrete structures, reinforced concrete non-pressure pipes and all kinds of items otherwise. Speaking otherwise, addressing the significant producers engaged in the construction firm is capable of only one order to provide themselves with all major building materials. And it saves time and, naturally, is capable of make the construction more favorable monetary policy. The global financial crisis, no doubt, had to have at least something to learn. And he managed to teach us first of all thrift. Just the very sound economy, where important, not very low cost, and the best price and quality.

Cement

The word "cement" comes from the German "zement" or Latin "caementum", which means gravel, broken stone. Cement has been known since ancient times. . The first variety of cement were gypsum and lime. The Egyptians and Greeks in the construction structures used cement. Some of the buildings of those times still remain, indicating a tremendous strength of cement and its timeless.

Dry cement – a mixture of loose, non-organic powdery substances. In contact with water, forms a mass of dry cement for construction. This mass quickly hardens and turns into stone. Cement – one of the main building materials. With the use of cement build houses of brick, concrete, foam blocks. Our cement Moscow just that. It is known that in ancient Rome, was also used cement.

These were the mortar with the addition of crushed volcanic rock. In Kievan Rus to the 17 th century in the mortar was added ceramic brick. This brick attached solutions ability to solidify and the resulting mixture was used the same cement Moscow. In 1825, cement was invented in the form in which it exists now. Cement – a material that bringeth construction on a new level of quality. Construction companies and factories for the production of cement is still conducting research and development material of higher quality. With the help of scientists cement is cheaper, greener and more durable. Using the latest scientific achievements in chemistry and construction, cement powder from primitive ancient turns into a high-tech mix, affordable and indispensable in the life of modern cities.
