Nails slate: characteristics, description, photo

For the laying of piece roofing materials, until now, no better fasteners have been invented than slate nails. However, in the market of building materials 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 qualitative characteristics of these products before purchasing.

Description

Slate nails are intended for installation of appropriate covering material. They consist of a rod and a head part, whose diameter 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 performed 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 on 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 execution. It also has certain standards, and they look like this: GOST 14918-80. Due to this material, which forms the basis of the head part, nails are almost not subjected to corrosion processes, and when installed only partially deformed. As a result, they almost exactly repeat the outline of the surface, ensuring tightness at the point of installation. The head part is obtained by the technology of hard rolling of the cap, it is attached to the nail, as a result, it is possible to obtain a rigid connection of the cap to the nail core.

Weight and dimensions

Slate nails must meet certain parameters, among them weight and size should be highlighted. The most popular today are products whose diameter is 4-5 mm. As for the most popular length, it varies from 90 to 120 mm, as an intermediate value are 100 mm. Slate nails have such parameters for the reason that they should be installed on a covering material having certain dimensions of the wave. The diameter of the head part should be 4 times the diameter of the rod, but the height of the head is the standard value and is 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 about 6 kg. Sometimes manufacturers use wooden packaging, its volume can vary from 25 to 30 kg.

Cost

Choosing nails slate, consumers are guided not only by weight and size, but also by the cost. The technology of manufacturing the described products is not so simple that it leaves its imprint on pricing. However, in this matter, an additional number of factors play a role, for example, here it is possible to include a retail price, which is set by trade organizations and can not be controlled. For example, at the enterprise you can buy nails at a price of 52 r. Per kilogram, this cost is correct for a large wholesale. If the wholesale is small, the price can reach 90 rubles. To predict, what will be the cost in a retail point, there is no possibility.

Features of installation of slate nails

The weight of the 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 fastener installation technology. Nails are set starting from the right side of the lower boundary of the ramp. Sheets should be overlapped. Holes for installing nails should be done with an electric drill or a hand tool.

The diameter of the hole should be more by two 2 mm compared with the same parameter characteristic of nails. Nail slate 5x120 is perfect for fixing the covering material. It should be metal and have a rubber washer, it is smeared with varnish on all sides, and then installed in a prepared hole, hammering it with a hammer. The optimal 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 the excess lubricant is released from under the washer.

Hats nails in the next stage are smeared with linseed oil, and on top after complete drying they are painted in the color of the slate sheet. Slate nails are used not only for laying the covering material, but also for assembling the disks. They cover the roof slope, which adjoins the edge. These are the elements of the oblique parts of the 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 the fixing is carried out on the crate by the same technology that was used for fixing ordinary sheets.

Extraction of slate nails

Slate nails, the GOST of which was mentioned above, can be extracted from the installed roof. Such a need may be required when the design has begun to flow. 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 using a nailer, then it will be possible to remove the entire sheet.

The weight of slate nails, depending on the size

Slate nail, the photo of which is presented in the article, can be used for laying the 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. The nail slate 5x120, which weighs 13.3 kg, can also be purchased from you in the store.

Conclusion

The nail production technology for slate is almost the same as the manufacturing process for conventional building nails. At the same time, equipment is used, which is called a nailing machine. As a raw material serves as a slate fastener, which has the appearance of a light thermally untreated wire. It is delivered to factories in bays.
