Sliced boards differ from simple edged boards in that they are processed from all sides by planing and subsequent grinding. Today, this type of lumber is considered the most popular, since it can be used at any stage of construction work. Let's get acquainted in more detail with the description of the operational characteristics of planed boards.

What it is?

The modern construction market is distinguished by a wide variety of lumber presented. Wherein every variety is characterized by its operational parameters, dimensions and cost.

In the process of processing, the tree is sawn into separate boards, some of them remain edged, and the other is dried in a heat chamber, where it spends about 3 weeks. Then the workpieces undergo processing, during which their geometry is leveled, any burrs and irregularities are eliminated. Modern woodworking technologies are automated, they do not damage the wood, therefore the exceptionally high quality of the boards is combined with a democratic cost.

Sliced wood has a number of undeniable advantages:

  • due to artificial drying, the moisture content of the finished material is 8-14%, which increases its hardness and duration of operation;
  • resistance to UV radiation and water;
  • increased strength and density;
  • perfect geometry of slices;
  • Smooth surface;
  • lack of warpage, deformation and cracks;
  • decorative appearance, natural texture;
  • light woody aroma.

How do they do it?

You can make a planed board both at home and at the factory. In the first case, they usually resort to manual processing with a plane or an electric plane. The final quality of lumber will directly depend on the professionalism of the specialist and his experience in working with wood . It is very important that the pressure on the working tool is the same throughout the entire processing. Otherwise, the board will be uneven, with noticeable stripes and height fluctuations. At the factory, electromechanical equipment is used for the production of boards - a planer, as well as a planer or a thickness gauge. Such installations themselves regulate the width and thickness of the cut, and special mechanisms ensure the evenness and cleanliness of the cut.

At home, there are situations when it is necessary to process a painted board . In this case, you first need to remove the paint - this can be done with special chemical washes. Keep in mind that you can only work with them using special protective equipment. A good effect is given by heating the board with a building hair dryer, after which the coating is easily cleaned off with a chisel or metal mesh.

Some craftsmen use a plane - this method can in no way be called successful, since the density of the varnish-and-paint components differs from wood. As a result, the knives become clogged and dull, usually after such work they have to be changed.

How do they differ from unplaned boards?

The main difference between planed lumber and edged counterpart comes down to a number of differences

  • Trimmed blanks are either dry or wet. Not so long ago, another type of sawn timber appeared in stores - a wet board impregnated with antimicrobial drugs.
  • Planed materials are dried in an industrial environment, so their moisture content is much lower.
  • Edged board may have irregularities and burrs. Sliced - undergoes turning, which creates a perfect cut, removes any roughness.

As a result of planing, the lumber becomes absolutely smooth. Such blanks are optimal for painting and varnishing without prior mechanical action. At the same time, the cost of a planed board is not much higher than an edged board, this is due to the complete automation of all production processes.

Species overview

According to the degree of humidity

The most popular in the construction segment is considered to be dry board, brought to condition in specialized drying chambers under the influence of artificially created heat. Such processing allows the material in the future to easily transfer contacts with moisture and not undergo rotting during operation.

The price of a dry board will be higher than a wet one, since the drying process significantly increases the cost of time and energy.

By the type of cut

According to the sawing principle, planed boards can be tangential or radial. The second technique produces more durable lumber . However, the first method allows you to get a more textured and beautiful look, and therefore is more in demand.

In recent years, boards with a fire-prevention chamfer have become widespread . Such lumber has a beveled end edge - this solution increases the ignition time of the structure in case of exposure to open fire, and they look much more aesthetically pleasing. Rolled boards with a rounded edge are no less popular. Such boards are in demand as platbands and other decorative elements of interior decoration.

By grade

For the production of planed timber, they use pine, beech, oak, as well as other, more exotic types of wood - sandalwood and ebony, as well as cedar. Depending on the quality level of finished products, boards are assigned one or another grade: The third grade is the lowest quality material . Such boards are used when performing rough work.

In the workpieces of the second grade, traces of the vital activity of insects and fallen out knots may be present, in small quantities. The first grade may contain a minimum amount of cracks and chips.

The highest grade is suitable for finishing floors and walls and for creating furniture.

Dimensions and weight

Usually the length of the planed board is not more than 6000 mm. This is due to the fact that in the production of planed boards, there is often a high percentage of rejection of raw materials. In addition, the length of 6 meters is convenient for transporting lumber. The technical capabilities of trucks, as a rule, are limited to a length of 10-12 m and, if you transport longer materials, they may freeze . In railway containers, such lumber is compact and does not go beyond.

The section of planed blanks usually corresponds to the parameters of 15 and 45 mm., In stores there are models with dimensions of 20x100, 45x95, 40x150, 150x50, 100x10 and 50x200 mm . However, after drying in the chamber, the cross-section can lose up to 5 mm of fiber on each side, so in practice you can see thinner boards with parameters 45 by 195, 35 by 145, 35 by 150, and also 45 by 90 mm. The best-selling boards are 150x50x6000 and 45x145x6000 mm.

Nuances of choice

When buying a planed board, first of all, you need to decide on the type of wood. For the construction of enclosing structures and roofs, you can use budget species - oak or larch . For covering floors and walls in a residential building or building a bath, it is better to give preference to cedar. Particular attention should be paid to the parameters of humidity - it should not exceed 10-14% for the interior facing of the premises and 18% for the exterior. Damp wood can be distinguished by its smell; it has a pungent wood scent. Some sellers claim that 20% moisture is quite enough for the operation of lumber, and this really complies with GOSTs. But, as practice shows, the use of workpieces with a moisture content exceeding 18% always increases the likelihood of decay after a short time. The percentage of moisture is necessarily indicated in the instruction manual for the board, if there is no indication of it, this is a reason to refuse to purchase.

Pay special attention to the cost of the products . Excessively underpriced indicates that the material is out of stock or has not been properly processed. There cannot be any voids visible to the eye in the boards - this is a sign of insect infestation. You can calculate the voids by sound, lightly tapping on the lumber - the sound will be dull. High quality planed lumber must completely exclude the presence of knots, such workpieces must be rejected immediately. There should be no stains, darkening, cracking on the surface, the geometry should be extremely correct.

If you put several boards on top of each other, then they should lie in an even pile with no visible gaps. This is a telltale sign that the material has been cut straight.

Areas of use

Sliced board has found wide application in manufacturing and construction. It is used for:

  • execution of wooden enclosing structures;
  • cladding of balconies, terraces, roofs and facades;
  • finishing of beams and imitation of timber for ceilings;
  • finishing of country houses, summer showers, gazebos and outbuildings;
  • installation of a finished floor in residential and industrial premises;
  • manufacturing of shelves, bedside tables, stools and other types of furniture.

Sliced boards are often used as additional materials, due to which structural elements are aligned. Despite the fact that the modern market is replete with artificial analogues of wood, most of the consumers prefer natural material. Wood was and remains the most environmentally friendly, and therefore the safest material.
