Laminated chipboard (LDSP) is a chipboard with a layer of protective laminating film, impregnated with waterproof and water-repellent resins applied to the surface. And according to GOST laminate wood-chip plates only of the highest grade with a smoothly ground surface. Laminated wood chipboard is favorably different from its simple moisture resistance, durability and beautiful texture at affordable price and simplicity in processing.

These qualities made LDSP the most popular material for the production of furniture, finishing works. He also finds the application in the production of containers, formwork. Furniture from LDSP can be bought, but you can make yourself individually for individual sizes and with the necessary functional – it will be perfectly fit into any interior and, with proper care, will serve many years. In this case, to correctly calculate everything, it is useful to get acquainted with what the dimensions, weight and density of laminated chipboard.

Standard dimensions

So that the stove withstand the load, did not break, did not bete, like a paper sheet, it should have certain proportions and the ratio of linear dimensions, thickness and stiffness. Therefore, for LDSP there are certain calculated dimensions. Standard is the dimensions that are defined in GOST 33289-2013. In length, this is 19 values ​​ranging from 1830 to 5680 mm, in width 9 values ​​from 1220 to 2500 mm:

  • length – 1830, 2040, 2440, 2500, 2600, 2700, 2750, 2800 2840, 3220, 3,200, 3600, 3660, 3690, 3750, 4100, 5200, 5500, 5680;
  • width – 1220, 1250, 1500, 1750, 1800, 1830, 2135, 2440, 2500.

In this case, the standard is determined that the edges should be strictly straightforward (permissible deviation of not more than 1.5 mm per 1 meter).

The most running formats are 2440 x 1830 mm, 2500×1830 mm, 2750×1830 mm, 3500×1750 mm. LDSP sheets of such format produce all the leading companies – Egger, Kronostar, Kronospan, Swisspan, Uvadrev Holding, “Shexninsky Wood Plate”, “Cherepovetsky Fanroom Furniture Plant”, “Syktyvkar Plywood Plant” and others.

Also, the standard assumes that manufacturers can determine product dimensions with other parameters. It all depends on the capabilities of the equipment and the needs of customers. Typical for the Russian market steel sheets with dimensions: 2500×1850, 2620×1830, 2800×2070, 3060×1830, 3060×1220. They are included in the standard dimensional line of Kronostar, Kronospan, Swisspan and other companies, are widely represented in wholesale and retail. Also often produced small sheets with dimensions of 500×500 mm, 600x500mm.

By customer specifications can be made LDSP with non-standard dimensions. They can have special types of edges and coating (fire, frost-resistant). As a rule, such products are available on request of furniture companies.

What a thickness happens?

GOST defines that the minimum thickness of the LDSP may be from 3 mm. And then it can have any value, a multiple of 1 mm, and is limited only by the technological possibilities of production. Usually, Equipment of most companies is configured to release LDSP thickness 8, 10, 12, 16, 18, 20, 22, 25, 30, 32, 38 mm – They are considered a strange industry standard. Some companies also produce 19 mm compounds. And plates thick 5, 7, 13, 17 mm are very rare and usually are made to order.

Maximum standard thickness manufacturers are considered 38 mm. But at a special order, some companies are taken to make plates thick 40, 50 and even 100 mm. LDSP increased thickness, as a rule, are used only for narrow industrial tasks. For ordinary furniture, they are too heavy.

The thicker the plate, the greater weight she can withstand. Therefore, thin sheets (3-10 mm) are used for decorative elements of furniture, small shelves, as well as for facing the premises. For high-loaded elements (massive countertops, supporting walls of housing furniture, shelves under heavy things) thick sheets are used – from 20-25 mm.

The most universal and in demand are LDSP medium thickness – from 12 to 20 mm. They are suitable for creating most furniture parts (including the ribs of stiffness of not very loaded cabinets), as well as for decoration of walls, floors, creating partitions of residential and office space. According to the statistics of construction hypermarkets, most often acquired laminated sheets with a thickness of 16 mm.

Weight plate

It is clear that the larger the area and the thickness of the LDSP, the more she weighs. But the weight is determined not only by dimensions, but also:

  • Quality and variety of raw materials – the density of the fibers of trees of different rocks differs, and the chip materials of them will also have different density and weight (the most dense and high-quality birch);
  • Pressing density, connective compositions for gluing raw materials and even chip geometry – the more cavities stay between chips, and the more poorly impregnated with glue areas, the more fragile there will be a stove;
  • Humidity plate – According to standards, it must be in the range of 5 -7%.

Therefore, sheets with the same overall dimensions, depending on the production technology, may differ by mass, and their density (proportion) will also be different. At the same time, it is the density that determines the permissible mechanical load and other important performance characteristics. GOST standards define a permissible density range in a fairly wide range of 550 – 850 kg / m3. The averaged settlement values ​​are given in relevant reference tables. For example, the weight of 1M2 LDSP thickness of 10 mm will be as follows with different density values:

  • 550 kg / m3 – 5.5 kg;
  • 700 kg / m3 – 7.0 kg;
  • 820 kg / m3 – 8.2 kg.

According to the fact that the actual value from the calculated, the professional may judge the technology of manufacturing a laminated wood chipboard and whether its quality complies with the declared manufacturer. For example, the production of leading companies is slightly different from average density values ​​and complies with standards. For comparison, we present a lot of LDSP with an area of ​​1 m2 and a thickness of 10 mm from market leaders:

  • Egger – 7.04 kg;
  • KRONOSPAN RUSSIA – 7.1 kg;
  • Swisspan – 7.8 kg.

If differences from medium and standard values ​​are essential – this indicates a violation of production technology, such a stove will easily break and crumble, will not withstand regulatory loads. The thickness and quality of the application of the laminating layer on the weight affects very slightly – these are the interests of the percent. But the rigidity of the upper layer is the most important indicator that affects whether fasteners will hold.

How to choose dimensions?

First you need to perform measurements and determine the total size of the product so that it fit into the intended space. Then constitute a detailed drawing where all parts are calculated and indicated. This will make it possible to correctly calculate the desired amount of material, pick up the fastener type.

For each part, depending on the load, there are its optimal proportions. For convenience, you can focus on the sizes of furniture, the reliability of which is tested by experience not one generation of masters. For example, for a cabinet with a standard depth of 600 mm, the recommended maximum shelf length with a thickness of 16 mm should not exceed 600 mm, and with a thickness of the shelf 18 mm – 800 mm.

If you plan to build complex furniture with a variety of functional elements and non-standard sizes, then it is better to use specialized programs to draw up the drawing (Cutting 3 or similar) or order a project from a private specialist, a profile company. In this case, you will need to consider a lot of factors, it is difficult to calculate them by hand and even a professional, not the newer.

The advantage of specialized programs before the “manual” calculation is that they will help to choose the area of ​​the sheets and the number of saws so that the residue is very small when cutting, and it did not have to overpay for excess material.

Cutting can be entrusted to specialized companies, which produce it on the machine, getting high quality edki handling. But you can cut the LDSP and independently, the main thing is to not allow the cracks of the material and be sure to treat the edge.

When stripping and cutting, it is important not to forget to lay a margin of material for the edge, if it is planned more than 0.5 mm (for example, a flexible or hard CANT PVC). Neglect the size of the edge can only if it is less than 0.5 mm (melamine tape, acrylic varnish, PVC-0.4).

Since the sale presents a variety of sheets of sheets, find the material of a suitable area is easy. Especially since developing standard sizes line, many manufacturers are focused on the popular dimensions of furniture parts. therefore for typical products often do not even need to cut.

For example, the size of the sheets of chipboard can already be found along the size of the finished table top and with the treated edge. It is enough to purchase such a sheet, install it on the frame, attach the legs from suitable bars – and a simple dining or writing desk ready. Despite the simplicity of the design, it will look stylish thanks to the aesthetic type of LDSP. From the variety of options, you can choose from any surface texture, pattern, color.

Sheets with a side of 2500 mm correspond to the typical height of the cabinet.

Square can be chosen any, but it is important that it is not too big – otherwise the canvas will be fed, move with an effort, destroying the guides.

Typically, the width of such a door is not done more than 1800-2000 mm. Therefore, if the cabinet is long, then it is more expedient to make 2 or 3 doors of smaller size than one canvas of a huge area.

To give a larger stiffness, the door for a wardrobe is often framed by a metal or plastic profile. This allows the use of small thickness sheets – usually take 8, 10, 12 mm (they are not too heavy, the standard profile dimensions are suitable for them). The distrust door makes thicker – 16 mm. But in any case, the weight should be coordinated with the possibilities of the fastening system and the driving mechanism – the limit loads that they can withstand can be obtained from the accompanying documentation.

It is also easy to find a finished sheet of suitable dimensions for the manufacture of a bed, the backrest of a standard bed, a cabinet. For carrier walls of cabinet furniture use a thickness of 20-38 mm thick. Sheets of small dimensions are used to create shelves, bedside tables, chest of drawers, hinged cabinets. For the walls of the walls, it is usually taken small in size to the panel thickness not more than 10 mm.
