To date, no better fastener has been invented for laying piece roofing materials than slate nails. However, in the building materials market today you can find fakes that "refuse" to fulfill their purpose, 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 nails 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 the nails were made according to them, then they should be based on low-carbon wire, which complies with GOST 3282-74.
As for the caps, galvanizedsheet steel. There are also certain standards for it, and they look like this: GOST 14918-80. Thanks to this material, which forms the basis of the head part, the nails are almost not exposed to corrosion processes, and during installation they are only partially deformed. As a result, they almost exactly follow the contours of the surface, ensuring tightness at the installation point. The head part is obtained using the technology of rigid rolling of the cap, it is mounted on a nail, as a result, it is possible to obtain a rigid connection between the cap and the nail shaft.
Weight and dimensions
Slate nails must meet certain parameters, among them weight and dimensions should be highlighted. 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 acts 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 of 4 mm.
There is another indicator that determines the mass of the nail. This unit determines 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 can hold approximately 6 kg. Sometimes manufacturers use wooden packaging, its volume can vary from 25 to 30 kg.
Cost
Choosing slate nails, consumers are guided not only by weight and size, but also by cost. The manufacturing technology of the described products is not so simple, which leaves its mark on pricing. However, an additional number of factors play a role in this matter, for example, this 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 rubles. per kilogram, this cost is correct for large wholesale. If the wholesale is small, then the price can reach 90 rubles. It is impossible to predict what the retail price will be.
Features of installing slate nails
The weight of a slate nail is calculated per kilogram of products, it was discussed above. However, in order for the product to perform its functions, it is also important to familiarize yourself with the technology for installing fasteners. Nails are installed, starting from the right side of the lower border of the ramp. Sheets should overlap. Holes for installing nails must be made with an electric drill or hand tools.
The diameter of the hole should be larger by two 2 mm compared to the same parameter characteristic of nails. Slate nail 5x120 is perfect for fixing covering material. It must be metal and have a rubber washer, it is from allsides are coated with drying 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, while the dimensions of the fastener should be 4x10, while the diameter of the washer should be 18 mm. The nail is driven in until excess grease comes out from under the washer.
Nail heads at the next stage 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 the covering material, but also for mounting the joints. 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 closely as possible to the rib beam, and fixation is carried out on the crate using 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 by loosening the fastenings of the surrounding elements. Nails are partially removed or completely removed with a nail puller, after which it will be possible to remove the entire sheet.
Slate nails weight depending on size
Slate nail, the photo of which is presentedin the article, you can use it 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. A slate nail 5x120, which weighs 13.3 kg, can also be purchased at the store.
Conclusion
The production technology of nails for slate is almost no different from the process of making ordinary construction nails. In this case, equipment is used, which is called a nail machine. The raw material is slate fasteners, which has the appearance of a light, thermally untreated wire. It is delivered to factories in coils.
