Until now, no better fasteners have been invented for laying piece roofing materials than slate nails. However, on the market of building materials today you can find fakes that "refuse" to fulfill their mission, they break and bend. That is why it is recommended to familiarize yourself with the quality characteristics of these products before purchasing.
Description
Slate nails are designed to install the appropriate covering material. They consist of a rod and a head part, the diameter of which can reach 14 mm. Like any other material, this one must be manufactured in accordance with state standards. The most common brand of slate nail are products that are made according to GOST 9870 standards. On the market you can find products made according to Russian standards PCT 1822-83. If nails were made according to them, then they should be based on low-carbon wire, which corresponds to GOST 3282-74.
As for the caps, galvanized sheet steel is used for their implementation. There are also certain standards on it, and they look like this: GOST 14918-80. Thanks to this material, which forms the basis of the head part, nails almost do not undergo corrosion processes, and during installation they are only partially deformed. As a result, they almost exactly follow the surface shape, ensuring tightness at the installation point. The head part is obtained by the technology of rigid rolling of the cap, it is mounted on the nail, as a result it is possible to obtain a rigid connection of the cap with the nail shaft.
Weight and dimensions
Slate nails must meet certain parameters, among them we must highlight the weight and size. The most popular today are products with a diameter of 4-5 mm. As for the most popular length, it varies from 90 to 120 mm, 100 mm act as an intermediate value. Slate nails have such parameters for the reason that they must be installed on a covering material with certain wave sizes. The diameter of the head should be 4 times the diameter of the rod, but the height of the head is a standard value and is 4 mm.
There is another indicator that determines the mass of the nail. This unit sets how much 1000 nails weigh. For slate products, this parameter varies from 11 to 14 kg, the final figure will depend on the size of the products. They are usually delivered in cardboard boxes, each of which is capable of holding about 6 kg. Sometimes manufacturers use wooden containers, its volume can vary from 25 to 30 kg.
Cost
Choosing slate nails, consumers focus not only on weight and size, but also on cost. The manufacturing technology of the described products is not so simple that it leaves its mark on pricing. However, an additional number of factors play a role in this issue, for example, here we can include the retail price, which is set by trade organizations and cannot be controlled. For example, at the enterprise you can buy nails at a price of 52 p. per kilogram, this cost is true for large wholesale. If the wholesale is small, then the price can reach 90 rubles. There is no way to predict what the retail price will be.
Features of installing slate nails
The weight of the slate nail is calculated per kilogram of production, it was discussed above. However, in order for the product to fulfill its functions, it is important to familiarize yourself with the technology of installing fasteners. Nails are installed starting from the right side of the lower edge of the ramp. Sheets should be overlapped. Nail holes must be made with an electric drill or a hand tool.
The diameter of the hole should be two 2 mm larger compared to the same parameter inherent in nails. 5x120 slate nail is perfect for attaching cover material. It should be metal and have a rubber washer, it is coated on all sides with linseed oil, and then installed in the prepared hole, hammering with a hammer. The best solution for such work will be nails with a prefabricated head, the dimensions of the fasteners should be 4x10, while the diameter of the washer should be 18 mm. The nail is driven in until excess grease is released from under the washer.
At the next stage, the nail hats are smeared with drying oil, and on top, after complete drying, they are painted in the color of a slate sheet. Slate nails are used not only for laying covering material, but also for mounting spacers. They cover the roof slope adjacent to the rib. These elements are oblique parts of sheets, the dimensions of which are determined at the installation site. Their laying is carried out as tightly as possible to the rib beam, and fixing is carried out on the crate according to the same technology that was used when attaching ordinary sheets.
Removing Slate Nails
Slate nails, the GOST of which was mentioned above, can be removed from the mounted roof. Such a need may be required when the structure began to leak. In order to replace the elements, it is necessary to remove the damaged sheet, loosening the fastening of the surrounding elements. Nails are partially removed or completely removed with a nail clipper, after which it will be possible to remove the entire sheet.
Weight of slate nails depending on size
A slate nail, the photo of which is presented in the article, can be used by you for laying covering material. If you want to calculate the approximate cost of products, then you need to know their weight depending on the size. For example, products with dimensions of 4x90 mm will weigh 10.5 kg, if the dimensions increase to 4x100, then the weight is 10.93 kg. 5x120 slate nail, whose weight is 13.3 kg, can also be purchased by you in the store.
Conclusion
The technology for the production of slate nails is almost no different from the process of manufacturing conventional building nails. This uses equipment called a nailing machine. The raw material is slate fasteners, which has the form of a light thermally untreated wire. It is supplied to factories in bays.
