Construction frame houses, V Lately, is gaining more and more momentum. This is due to the fact that frame house construction can make your dream come true in the shortest possible time, giving you your own, countryside, warm, natural and environmentally friendly clean house. In addition, we note that frame houses are relatively inexpensive, because their construction implies savings on the foundation, as well as the use of labor.
The strength of such structures is undeniable. The fact is that thanks to innovation, new types of fastening elements have recently begun to be actively used, one of which is the nail plate. Actually, we will talk about what exactly this fastener is in this article.
Nail plate, application features
Such fasteners are supplied to the market building materials in the form of a plate, which is made of alloy or galvanized steel. The latter allows the plate not to oxidize or rust, performing its functions for a fairly long period of time. This plate is called a nail plate because nails (spikes) obtained during stamping protrude perpendicular to its plane. The average length of one spine is from 8 to 9 mm. Depending on the purpose, one plate with nails may have different number strips with teeth.
The plate itself is very thin, which allows it to be used at almost any stage of house construction. However, the main area of application of the plate is the construction of a rafter system. In this case, the dimensions of the fasteners are selected based on the dimensions of one rafter. As a result, a plane, say, 50 mm wide and 110 mm long, allows you to fasten rafters located in the same plane without using an additional fastening element, including nails and screws.
One of the main problems that a potential consumer may encounter when using the plate is natural humidity tree. As you know, wood dries out during use, changing its shape, weight and volume. In this regard, when using a plate with nails, for example, when building a log house, you should not skimp on the foundation, so that the effect of changing the geometry of the building does not increase due to the subsidence of the house under its weight. Only in this case, nail fasteners can fully reveal all their useful properties:
- Powerful and durable connection. It has been scientifically proven that today no fastener can compete with a nail plate. At the same time, it does not damage the integrity of the tree, does not lead to rotting, and does not cause cracks and chips.
- Complete absence of swaying of the rafters, even in strong gusty winds. In this case (of course, if an even cut is made) the “monolithic” base of this fastener ensures the tightest connection.
- No shrinkage. Even if your house is not built well enough and during its operation it shrinks, rest assured that the geometry of the rafter system will not cause curvature, which will not lead to a change in its shape.
- Doesn't rust. Some models of plates are additionally coated with galvanic coating. But even without it, rust will be completely absent.
- The installation process of such fasteners does not require the use of electrical priors. In addition, when compared with conventional nails and self-tapping screws, it must be said that installation of a nail strip is much faster.
- Low cost. Buy nail plate for construction own home everyone can. In general, it is sold in any city in our country, but in Moscow, it can be purchased at the address: Moscow region, Balashikha, st. Sovetskaya, 35.
- Excellent compatibility with any tree species. There are cases when metal dowels are simply rejected by the tree, as a result of which the wood begins to rot and will soon require replacement. In the case of a nail plate, this is guaranteed not to happen during the entire life of your frame house.
The construction of frame houses is gaining popularity: they are relatively cheap and comfortable. In classic designs of houses and structures made of stone, brick and other materials, rafter systems are made of wooden elements, therefore, the issue of reliable connection of beams, beams or other wooden elements is constantly relevant. Recently, the nail plate has been widely used - a new product among fasteners, which has successfully replaced nails, dowels and screws.
Design and material of manufacture
From the name it is clear that the design of a nail plate is a strip of metal with an analogue of nails. Its thickness ranges from 1 to 2 mm, dimensions vary from 40 to 200 mm in width, and the length can be any. U different manufacturers your size standards. Most often, nail plates are produced in length increments of 25 mm.
Source material for production is high-strength sheet alloy or galvanized steel. In production, it is cut into plates of the required size, and then thin protrusions up to 8 mm long are extruded using a special press. They play the role of nails, firmly entering wooden structures.
Application area
Any wooden structures that are connected to each other must have an overall rigidity to maintain bearing capacity and preventing deformation of the entire structure. The fastener that best copes with this task is nail plates. They are used in residential, public, and industrial construction during the construction of frame wooden structures and installation rafter systems.
Methods of use
Production wall panels, or arches carried out in production workshops. The structural elements are fixed in jigs or other devices and connected with a nail plate using a press. This connection method is of the highest quality, but it is not always possible to use it.
It is not possible to use nail plates using a press on a construction site. They are simply driven in with a hammer and at the same time ensuring that the protrusions fit evenly into the wood.
Main advantages
The popularity of nail plates is due to their advantages over other types of fasteners:
- the ability to connect elements in one plane without significant protrusions on the surface;
- low dead weight, which reduces the overall weight of the structure;
- the use of nail plates makes it possible to mount complex systems gradually without the use of heavy construction equipment;
- reduction in the total cost of the constructed facility (prices are quite high, but the fasteners in question are relatively inexpensive);
- the use of a plate increases the rigidity and strength of joints in composite structures;
- Installation of a nail plate is quite simple and does not require specialized knowledge.
Existing disadvantages
This type fasteners are not without their disadvantages, of which the most significant are the following:
- low strength and rigidity under bending loads at the joint;
- manual installation of nail plates does not always provide maximum rigidity and strength of the connection;
- To obtain a high-quality structure with precise design dimensions, a platform with ideal evenness is required.
Types by tooth arrangement
Manufacturers often try to reduce the price of the building materials they produce. One way to do this is to simplify the design and production technology. Because of this, most of the nail plates used are the simplest and cheapest type with unidirectional teeth. But there are other options that are used in critical designs: with multidirectional teeth in adjacent rows and with teeth located at an angle of 45 degrees to the longitudinal axis of the plate. These options are more difficult to produce, therefore the price of building materials for fastening these types is slightly higher.
Classification and manufacturers
In LNG countries, a classification of MPZ (metal toothed plates - the name of nail plates according to GOST) has been adopted by thickness: MPZ-1.0, MPZ-1.2 and MPZ-2.0 are manufactured with a thickness of 1.0, 1.2 and 2.0 mm, respectively.
IN Western Europe A popular standard is the bi-directional gang-nail toothed key from manufacturing companies in Sweden, Germany, Poland and Finland. In Hungary and neighboring countries, nail plates from the Arpad company are popular, notable for their high strength. The price of one plate, depending on the type, size and manufacturer, ranges from 10 to 120 rubles.
Description:
The nail plate is designed to connect two individual elements made of wood. This method has gained wide popularity in the construction of frame houses due to 3 advantages:
- High strength while reducing costs. The prices for a nail plate are very affordable, and the joints created with their help are characterized by increased strength characteristics and resistance to mechanical damage. The plates themselves are cast from high quality carbon steel.
- Fast and convenient laying of communications. Using nail plates, the price of which is low, especially compared to the advantages of use, it is possible to install floors with special void corridors for installing a communication system.
- The installation time has been significantly reduced. If all construction and installation work has a strict time frame, then you need to buy nail plates. With their help, you will significantly speed up construction by introducing a method for remote installation of blocks and simplifying the procedure for connecting operations.

It is used for fastening the rafter part of the house, as well as for connections in frame housing construction. Does not require the use of nails. Installation using special equipment is recommended.
Characteristics:
- Material: GP, RK - sheet steel, GPZ - galvanized sheet steel.
- Thickness: 1.5 mm; 1.3 mm
The nail plate is used for fastening the rafter part of the house, as well as for connections in frame housing construction. It is a strip (plate) made from galvanized steel sheet with stamped nails (teeth). Production of nail plates using the cold stamping on hydraulic press allows you to obtain high-quality connecting elements. Standard insert teeth are 8 millimeters high. One nail plate can have from 2 to 16 rows of teeth.
The thickness of the nail plate is from 1 millimeter, the width can be, depending on the standard size, from 20 to 132 millimeters, and the length can be from 76 to 1250 millimeters. With the help of metal toothed connecting plates, wooden structural elements such as boards, beams, beams lying in the same plane can be connected without the use of nails, screws and other fasteners.
Why fastening can be a problem
The issue of fastening is very important due to the characteristics of wood, its “behavior” depending on weather conditions. With changes in humidity levels, wooden building elements decrease or increase in size and are often subject to bending. As a result, large and long-term “stresses” arise in the places of their connections and abutments. The reason for this may also be the construction of a light foundation or its complete absence (which is possible given the low weight and elasticity of wooden structures), leading to a change in the geometry of these structures.
When using a metal plate, increased corrosion resistance of the connecting element is ensured, which favors its operation in conditions high humidity, and also when performing external works.
Properties of nail plate
The connecting nail (toothed) plate has important advantages compared to other types of fastenings. For example, from separately driven nails, each of which is on its own.
-*Strength of bonding with wood is achieved shape of the teeth and their angle of inclination, arrangement in rows. At the junction of elements wooden structures The nail plate forms a connection with high strength properties that no other fastening element can compete with. These indicators have been verified by many mechanical tests of structures.
-*Common monolithic platform– the base on which all the teeth are attached eliminates the possibility of their mobility and swinging. The platform becomes common, binding basis for the connected parts of the structure, due to which the connection is again given the quality of strength.
allow us to provide excellent strength even when splicing wooden structural elements by butt connection.
-*Parts are attached extremely tightly. it's the same empirically proven. For example, a beam assembled using a plate of two butt-joined wooden beams, when exposed to a fracture, it broke not at the junction of the structural elements, but in the monolithic part of the beam. Thus, the monolithic nail plate platform completely prevents the teeth from moving or becoming loose and becomes reliable basis connecting node.
-*If necessary possible to apply electroplating – this is possible additional service at the request of the customer. This coating will give additional durability to the steel nail plate.
-*Metal toothed plates installed faster than traditional types fasteners, thanks to its unique design. This will significantly save time during construction and installation work on fastening elements of rafter and sub-rafter systems.
-*Due to the possibility of manufacturing floor beams with “corridors” specially designed for these purposes this method of fastening facilitates the laying of communications(ventilation ducts).
The listed qualities of nail connecting plates have become the reason for their widespread widespread use in the construction and construction of wooden structures for any purpose. The simplicity of the design of nail plates brings exceptional strength and durability to the connection.
Experience in using nail plates
Steel nail plates have been used for over twenty years in Canada and the USA, specifically in North America They began to be widely used in the construction of wooden structures. This fastening method is now widely used throughout Europe. With the help of industrially produced truss structures based on plates, you can build almost any type of roof, attic, attic spaces, skylights, etc.
Roofs using nail plates are applicable in all types of structures, for example:
- residential buildings,
-industrial,
- agricultural,
-sports and commercial facilities.
In addition to rafter structures, this technology can be successfully used for:
- reconstruction of buildings and flat roofs, where plates are considered an indispensable type of fastener;
- production of panels for walls;
- production of lattice frames,
- construction of formwork for concrete structures,
- construction of long-span premises made entirely of wood.
The possibility of creating trusses with a span of more than 30 meters without internal supports (for example, tennis courts), which has arisen in connection with the use of connecting plates, is widely used. The plates can be successfully used when joining boards lengthwise.
Tooth (nail) plate is a strong, fast and economical connection for wooden structures. Distinctive Advantages and the properties of this fastening contribute to its increasingly widespread use in construction wooden houses and structures in our country. The opportunity to purchase these products is becoming more and more accessible, and those interested can evaluate the convenience and quality of this fastener in practice.
