Often in construction uses various wood building materials. Enjoyment board uses in great demand. It can be made from a wide variety of wood. Such boards allow you to build strong, reliable and durable structures. Today we will talk about what features these products are possessed, and what kinds they are.
What it is?
The edged board looks like an ordinary sawn timber. At the same time, it does not have obol, that is, there is no bark on the edges of the products. According to the established standard, a small review still let’s say. This building material should have the right form in a section similar to a rectangle.
All edges on the sides are cut off. It turns out that not only the lower and upper parts are processed, but also side. The main characteristics for edged boards are humidity, variety and type of wood used.
Before processing such wood, specific dimensional values are defined. Most often, the edged board is used in the manufacture of various furniture designs, for the external and interior decoration of the premises, the construction of fences and frames.
A cutting board is made by cutting a whole log immediately from several sides. The obtained billets are necessarily dried to a certain level of humidity. This sawn timber is distinguished by high operational period.
Such building materials are simply mounted, they are easy to transport and store. These products can always be found in large quantities and at an affordable price, as they are in demand.
Norms and standards
A high-quality edge board must fully comply with all established state standards. The basic information can be found in GOST 8486-86. There are also indicated, including permissible dimensions.
GOST 18288-87, which contains a list of used technical terms in the sawmills, as well as specific determinations of sawn timber. GOST 24454-80 determines the share of permissible defects and deviations depending on the sorting and sizes.
The wide surface of the sawn timber is called in the Granta Plase, the narrow lateral part is the edge, and the end is formed by a spil on the source log.
In addition, enterprises engaged in the processing and production of edged board should receive a special certificate of conformity that will confirm the quality of the sawn timber.
Today there are a large number of types of edged boards. Each of them has its markup. So, They may differ from each other depending on the degree of humidity.
If the humidity is less than 12%, then this means that the boards are dry. They have less weight compared to the rest of the varieties. Such materials undergo a thorough drying in the processing process. Most often it is held in special drying chambers.
Sustaine will not be subject to defeats of various organisms. On his surface will not be able to appear mold and fungus. Dry boards have maximum strength and hardness. And they are practically not exposed to deformations.
Such a dried board with a minimum moisture content will not be dark with time. Products can be two types: planed and non-stroke. In the first case, first cut the log, it makes a simple cutting board. Then pick up high quality raw materials intended for future processing. For these purposes, remove the bark, drive under the desired size.
After that, careful drying and planing immediately all its faces. The wood surface must be perfectly smooth and smooth. Drying time will be directly dependent on the variety of wood and from the section. She usually lasts from a few days to 3 weeks.
As a result of this processing, smooth boards are the same size. This type of sawn timber is considered the highest quality, it is characterized by the lack of shrinkage, various defects.
Non-stroke variety, as a rule, is made from low varieties of wood. Most often coniferous breeds, including spruce and pine. These materials have a smaller price compared to the previous option.
In the process of processing, the side department with the bark is removed, but the whole surface is rough.
Such boards pass only natural drying, they are not sent to special drying chambers. The level of their humidity can fluctuate, but not exceed 22%. Raw varieties have a large size compared to dry.
These sawn timber are mostly applied when conducting external work. When properly processed on their surface should not be traces of rotting and livelihoods of various parasites and insects, large cracks and bitch.
Raw varieties can be used in the construction of the basement or when laying a rough floor covering. They are able to withstand a significant pressure of concrete, the products are practically not deformed in mechanical impacts.
These edged boards are subject to special processing. Antiseptic composition is applied to their surface. It allows you to protect the material from the processes of rotting, the effects of insects and parasites. At the same time, impregnation with antiseptics occurs exclusively in production scale in accordance with the established standards and standards.
Antiseptic lumber have a reddish tint. After such treatment, they become much more durable and durable. Such impregnations are used only on dry boards. Otherwise the substance simply will not be able to soak the tree.
There are several varieties of antiseptics that are used for wood processing: Made on an oil basis, aquatic, based on organic solvents. The first option is considered to be the most preferable, it is characterized by the highest level of protection of materials.
Edged boards can be made of various wood breeds. Consider each option separately.
Models made from coniferous woods are considered fairly reliable and high-quality. Most often they are made of pine and fir. Such boards are similar in their appearance and basic properties.
Pine has a slightly pink core, but over time it acquires a brown color. Such wood has an average density, it is considered quite durable, resistant to rotting. It is easy to handle this basis and cut.
A fir is a little inferior to pine in hardness, strength and density. It is distinguished by rather long fibers, white coloring. This breed is uniform. Such wood for the manufacture of sawn timber is processed a little more difficult, as it has a large number of small bitch.
Besides, Often used larch. This breed in dried form is practically not exposed to rotting processes, opposes the negative impact of moisture. The basis almost 70% consists of a kernel.
It is the kernel part that contains the main mass of the useful substances, which give the wood increased strength and resistance.
Fir can also be used when creating edged boards. This wood is non-uniform. Externally, it is very similar to her fir. The base has annual rings that will be visible on all sections.
Fir has a pretty dark color, it has large knots that are placed by mutters, between them you can see smaller knots. Such wood has reduced physicomechanical properties compared to fir.
Sometimes the cedar boards do. This coniferous wood is soft and light. It’s just to cut it and process it. Cedar is distinguished by increased resistance to rotting, not bad strength level.
The cedar core has a yellow-pink color, it highlights resinous masses. The tree is considered dense and durable, reliable and durable building materials are formed from it.
This group should include lumber made from maple. The edged board made from maple wood is characterized by the most attractive texture of pink or yellow shade. Products from this tree can easily hold various fasteners, including nails.
Maple base is pretty heavy and solid. It has considerable density and strength. Wood in dried form is the most resistant to the processes of rotting, moisture, ultraviolet radiation.
Such a tree is perfectly cutting and even the deepest treatment. And also, if necessary, you can easily cover paint, varnish, polish. Most often this board is used when creating a variety of furniture products.
This group should also include ash. The solid breed belongs to the family of oline. Wood is distinguished by high elasticity, durability. Structure of ash bright and motley. The tree practically does not absorb moisture, but with an excessive amount of water it may change in volume.
Wood ash in thermal processing will have an average thermal conductivity indicator. She will be able to approach the formation of warm floors. Often such boards are used when creating exclusive furniture.
Oak also applies to solid tree rocks. It has maximum strength and reliability. And the basis is characterized by an increased rigidity rate. Produced products made from oak, will be able to last as much as possible.
Oak billets are hard cut and processed. They have a significant weight. This tree is distinguished by a beautiful and interesting structure. Beautiful decorative properties have a starved oak, which was lying in water for a long time.
Aspen belongs to deciduous rocks. It has a white color with a slight green or blue tint. This tree is characterized by limiting, softness and relatively small mass.
Aspen can be in the water for a long time, and at the same time it will not lose its main properties and will not swell. When drying, the material does not crack. Wood easily gives back painting and processing.
Its surface has a dark color.
The beech should also be attributed to solid rocks. It has a pale cream colors. Book wood has a light natural shine. It is characterized by a lot of weight, rigidity and considerable density.
Bending is especially durable. In the production process, such boards are often processed by special impregnations, which significantly increase their durability. This wood base will be perfectly suitable for the manufacture of elite furniture, as well as for interior decoration.
This group refers Lipa. Such a tree is mild, it has an average density. Linden products have medium weight. They have white painting, sometimes there is a light pinkish tint.
Lipa is characterized by a characteristic light glitter. It has a smooth and homogeneous structure, there are practically no major veins on the surface. Such wood in the drying process dries as quickly and becomes much more dense.
Poplar can also be used to produce edged boards. When processing on its surface there may be a small durability. The material is well amenable to coloring and gluing in the manufacturing process.
Topol can not boast of high strength and wear resistance. In addition, it is often subjected to rotting processes. But at the same time, insects and rodents almost never amaze it due to excessive bitterness. The board made of such a breed has a relatively low cost.
Special decorative qualities have sealed wood, which is maintained for a long time in water, can be perfect for the production of a variety of decorations, carved products.
Birch is considered a soft breed, it is often subjected to rotting processes. In order for birch boards to serve a longer period, they are most often treated with special means of manufacture.
Birch wood is easy to paint, it is simply toned. Such a base is predominantly used in the production of small decorative items, figurines, caskets.
Tika boards can serve as long as possible. They have elevated resistance to rotting and formation of mold. This wood is easy to handle and dry.
It is characterized by minimal shrinkage.
Edged boards made from different wood species can have different sizes. The most common models are lumber with values of 15x150x6000 millimeters. And also there are samples 50×150 mm. Products 50 to 150 will be able to come together to carry out various construction work.
The length that is established by the State Standard may be 2, 3 or 6 meters. But if necessary, you can choose a 4 meter length. The width reaches 100, 150, 160 mm. Wide instances can reach 200 millimeters. Thickness, as a rule, is 40, 50 mm. Thin models with a thickness of 25 mm, 32 mm are also available.
How to choose?
Before buying a wooden cutting board, special attention should be paid to some important features. So, be sure to look at the tree of the tree, from which the sawn timber is produced. Remember, the grade of wood affects not only the appearance of the product, but also on the level of strength, quality and resistance. After all, each individual variety has its own properties and characteristics.
And also should be taken into account, for which purpose the material will be used. So, for the manufacture of furniture structures, preference should be given to larch. A spruce, oak base, pine can be set for construction work.
It is important to view the material for the presence of various defects, including cracks, chips, bitch and rot. In this case, the product is worth dividing into two main types.
First grade. In this case, wood will not have obol, other irregularities and defects on its surface. This specifies should be used when creating furniture, ornamental products.
Second grade. In the production of this wood, a certain amount of bitch is allowed, as well as a review. These samples should be used when conducting construction work.
It is necessary to take into account and the size of the boards. In this case, everything will depend on the specific purposes of use.
An important place when choosing is also occupied by the type of wood in humidity, it is possible to determine the level of humidity by weight of products.
Be sure to look at the crucible material. It can be several types.
Tangential. In this case, the cutting line will not pass through the core. As a rule, such models have low cost, they have a saturated beautiful texture, but at the same time they are less durable.
Radial. The cut line will pass through the central part. Boards of this type have a homogeneous texture, they are pretty durable and persistent, but their cost is relatively high.
Semiradial. In this case, the cut is formed at an angle of 45 degrees. Semiradial samples may be subjected to various deformations, they also do not boast of high strength.
The appearance of products will depend on the type of cutting, their resistance to various environmental factors. As well as painting of lumber depends on primary processing.
Scope of application
Edged board can be used in a variety of spheres. Often this material is used when creating an outdoor coating. At the same time, non-stroke models are better to take only for the formation of draft flooring.
Often the edged board acquire and for creating a roof frame, facade, veranda, terraces. Products that belong to the first grade are used for the manufacture of furniture, wall coverings, door production, windows and openings, railings for stairs, ornamental items.
The edged material can be used when erecting houses, bathrooms, stairs. At the same time, it is possible to lay items both in the vertical and horizontal direction.
If you purchase an exterior board, then you should choose a natural material that has a beautiful natural texture. In this case, preference should be given to the dried basics.
Dry board perfectly amenable to different treatments. Walls decorated with such a sawn timber will provide good thermal insulation, and will also decorate the interior of the room.
Edged boards will become the best option for the production of partitions, ceilings, styling the foundation. They will suit and for individual repair work.
