When sawing logs, as a rule, croaker … In fact, it is a board with one side convex. This type of lumber is one of the cheapest … However, despite this, it has a fairly wide application in various industries. There are different types of this lumber that can be used in construction, for making furniture, for receiving wood chips, as fuel, and so on.

What it is?

The logs are sawn so that when the edges are removed, a slab is formed. It usually has a flat side on one side, like a regular board, but the other side may be uneven or even barked. In the course of the wood processing process, a lot of waste is obtained, which sometimes includes the croaker. In fact, this lumber can be used to great benefit.

Sure, most often the slab is used as a heating material . However, it is more valuable and suitable for processing in order to create useful things and materials from it.

Lumber looks different, based on the type of processing and the quality of the original raw materials. The cost varies greatly depending on its type.

For example, the cheapest option is boards with the outer side in the shape of a semicircle with bark.

Such material is often called " lagging ", and it can be found on the sawmill without grading, cheap and in significant quantities. Of course, at large enterprises, slabs are packed in length and thickness, which somewhat increases its price. The most expensive types are wall paneling and block house . They are obtained as a result of careful processing, according to certain requirements. It is noteworthy that these types of lumber are equipped with grooves and dowels to make them easier to collect.

The croaker is especially good where you can safely save money. For example, during construction, you can make a roof or walls of utility rooms from it.

Also, this material is suitable for upholstery and even creating pieces of furniture . Moreover, such boards can be attractive in appearance and at the same time be in no way inferior in quality and strength to ordinary ones. The full wood ratio shows how the volume of wood is related to the volume of shredded wood materials obtained from it. For the slab, the average value of this coefficient is 0.43-0.48.

How is a croaker made?

Slab boards are obtained when, when processing a log, a layer with a certain thickness is cut from its side . In such works, only the thickness of the material obtained is of importance, and the resulting boards with a convex side are waste. However, the complex sawing process can be made more profitable by using everything, including the leftovers. Of course, to use the obapol, you have to pre-process it.

Most often, tree trunks are sawn on special machines, which have 4 saw blades each.

Software control allows you to configure the unit so that it simultaneously saws a log from all sides. In this case, you can set the required values of the thickness and length to which you want to cut.

If the planer can simultaneously cut a log only from two opposite sides, then everything will be somewhat more complicated here, since after processing it will be necessary to turn the workpiece along the axis in order to continue separating the slab. Sawing machines are on sale not only for industrial workshops, but also for private households.

The cheapest is the slab with the smallest thickness and width, because such boards cannot be processed using a sawmill . For more massive options, an antiseptic composition is applied to the bark so that the wood does not deteriorate, and then cut into the necessary pieces.

Textured and unspoiled sections of the obapol can be carved into lining. It is important here that it is initially of high quality.

You can also get a block house from such boards . In this case, it is necessary to ensure that no more than 3-4 large branches are located on a square meter of wood. Also important is the ability to make connecting grooves and dowels. In this case, the obapol can turn into a full-fledged log house, only cheaper and easier. Moreover, from this, its properties, both mechanical and physical, will not become worse at all.

Species overview

The sawn slab differs in various ways, including size, shape, wood species and condition. Full size should be measured with bark included . This parameter is used when calculating the lot size.

If the slab is planned to be used for specific purposes, then the size of the wood must be considered without taking into account the bark.

In this case, you can take the average for all boards or the minimum, which corresponds to the smallest. The shape of the scraps, as a rule, corresponds to the shape of the log, being part of it. That is why the croaker is quite diverse.

Quite often it is divided into the following types:

  • smooth;
  • with extension;
  • uneven.

Smooth slab boards have the same width and thickness. It is important to know that the tolerances for this category are set independently by manufacturers or sellers.

In the expanding type, width with thickness can smoothly change from thin to thick edge. In this case, the values should be measured from the thin side of the board.

All boards, the length of which changes non-linearly, belong to the uneven type of slab . It also contains all the material that is not suitable for the first two types.

Depending on the wood from which it is made, the slab can differ in strength when bending and squeezing, resistance to decay and other damage, resistance to high humidity . In addition, the color of the wood and its texture will vary. Usually waste on sawmills is sorted according to what trees they came from, or at least indicate the percentage of used wood species.

Depending on this indicator, it becomes clear what can be made from a slab . For example, birch, pine, spruce, aspen are suitable as an auxiliary building material. The oak type, as well as the larch type, is considered more valuable. They can be used for various finishing works.

The main types, into which obapol are subdivided, are wood and business . Based on what type it belongs to, you can clearly determine what this material will go to.

Woody

This type differs in thickness up to 3.5 centimeters . Such a cut slab is only suitable for firewood. It is also processed into wood chips, fuel, cellulose, plates, charcoal with a fine fraction. In the production of furniture as a whole, this type of slab is not used. However, it can be used to make components, as well as boards from wood fibers and shavings.

Wood slab is a very profitable material for the production of wood chips. After all, chips are obtained from it of the same quality as from wood of a business type.

This is very beneficial for industries dealing with wood processing - the cost of such leftovers is 4 times less than a business slab. Certain types of wood, for example, linden, pine, birch, alder, are especially valued as fuel for both private houses and boiler houses.

Business

This type is a slab that has treated surfaces . Most often, the length of the boards is 2 meters, and the width varies from 0.8 to 1 meter, but it can be different depending on the diameter of the tree. In this case, the thickness starts from 3.5 cm or more.

The use of business waste is very wide, ranging from the construction of formwork and other rough products, ending with parquet, fences, roofing materials.

Scraps or burnt pieces can be used to create simple pieces of furniture and various wooden utensils. Same this type is excellent as a cladding material for various buildings … The competent and rational use of such a slab can significantly reduce the cost of repair and construction work without losing quality.

Areas of use

The block house is widely used in the interior .… On the one hand, this option looks like a regular board, and on the other, like a neat log house. There is a groove in the profile on one side, and a tongue-and-groove on the other for quick assembly. As a result, you can get a pretty log masonry. Most often, a block house is made from coniferous or deciduous wood.

Most often, linden block house is used indoors, due to its warmth and softness.

For finishing the outer parts of buildings, it is better to use spruce lining. This option is also well suited for a variety of structures and as an element of decor in the landscape or fences.

Formwork, roof tightening and other building structures are most often made from obapol … This type of slab is often used in the mining industry to strengthen workings in mines or mountains. The best fortifications are obtained from cedar, larch, spruce, pine, and fir. Moreover, the material must be free of bast and rotten knots.

Waste wood is beneficial to use for fences and fences in private houses.

To get a good fence, it is enough to install supports, fill between them across the slats, and to them vertically attach slab boards with or without bark.

To increase the life of the material, it can be impregnated with an antiseptic and then covered with a layer of varnish or stain.

In order to determine the boundaries of a plot of land with individual plants, you can put a low fence made of a slab. Moreover, it can be easily dug into the ground by covering the bottom of the board with a layer of roofing material or roofing felts.

For small buildings, the slab can be used as a formwork . Moreover, after such use, it can still be used to heat a stove, fireplace or boiler. Slabs make good roof support structures … At the same time, the bearing capacity is similar in properties to prefabricated structures. In private households, wood waste can be used to make pallets … The resulting pallets are convenient for storing building materials, as well as salted barrels or cans.

If you remove the bark from the material, then you can make good country furniture, including benches, tables, bedside tables, a base for a bed, a swing

To protect the wood, it can be varnished . The croaker will also be indispensable when sheathing canopies and arbors. Moreover, it can be used both from the inside and from the outside. You can also make a roof from it.

Designers recommend using a slab when creating loft-style furniture. For example, a tabletop made of oak or larch will look very impressive.

It is important that the wood has a uniform profile, is bark-free and varnished.

If there are knots that are too large, they can be cut off, and the irregularities and gaps can be filled with epoxy and fluorescent powder. The end result is a great luminous table that will adorn any dining room or living room.

To get closer to nature, you can use waste lumber as a finishing material for walls and ceilings. Also, peeled boards are well suited for wall decoration inside a bath or sauna. Moreover, choosing coniferous trees, you can also bring a pleasant aroma of resin into the room.

Various crafts can be made from short pieces of slab. For example, a wall hanger with hooks for clothes. Craftsmen use valuable wood species to create a variety of souvenirs from them.

Recycling and disposal

It can be problematic for timber processing enterprises to process and dispose of slabs . After all, it not only takes up space, but also is the focus of various forest pests. Also, large mountains of waste increase the fire hazard. Of course, the easiest way to deal with unnecessary waste is by incineration, but this is not reasonable from an economic point of view. It is more profitable to sell it as a heating material.

There is also an option for processing waste into high-quality chips, from which you can then make sheets of OSB, fiberboard or chipboard.

This requires special equipment . It should be borne in mind that there are few such devices on the domestic market, but in many regions of production they are engaged in the creation of home-made machines for the manufacture of wood chips. In this process, the most difficult thing is to remove the bark quickly and efficiently so that the chips are as clean as possible.

The productivity of wood processing plants can also be increased by making briquettes and pellets for the furnace . However, here it is also important that the content of the bark is as low as possible. This is due to the fact that a large amount of sand and other non-combustible particles collects on the bast. Therefore, in the processing of slabs, an important point is the presence of debarking equipment.
