Product description

TORX screws are an indispensable component of the installation of sheet metal covers. In the offer of Blachy Pruszyński you will find excellent quality screws made of low-carbon steel, surface-hardened and covered with a special protective coating (up to 540 hours in a salt spray chamber). In addition, the screws are immediately equipped with a washer made of aluminum with vulcanized EPDM (ethylene-propylene-diene rubber), which guarantees protection of the joined sheet metal surfaces. What's more, it is characterized by very high resistance to temperature differences, both high and low, maintaining its physical properties and thus guaranteeing no damage to the combined surfaces. The shortest versions of the screws, the so-called "staples", are used to connect two layers of steel sheet (e.g. roofing sheet to a steel batten).

Do you have questions?

Is it possible to make copper machining at the steel roof?

When using copper, be careful because copper oxides are very aggressive and cause corrosion of other metals. Therefore, on buildings, it cannot be combined with other metal species (copper enters into contact and causes electrolytic corrosion of other metals).

Why is the metal roofing sheets recommended for the renovation of old roofs?

This is directly related to its low weight. In the case of old roofs, the trusses of the renovated houses are often somewhat damaged by time. Therefore, it is safer to use a metal roofing tile, which weight oscillates at 4.7 kg/m2, than almost ten times a heavier ceramic tile than it. However, it is always worth verifying the condition of the roof truss, with a specialist and make sure that it does not require renovation or replacement. In such cases, the safety of residents or building employees, as well as the assembly team, is always a priority. In most situations, however, the condition of the structure without major problems allows the use of roof tiles, while the use of ceramic tile would not be possible.

Can you use an angle grinder when cutting sheets?

Modern roofing exclude the use of angle grinders for cutting. The use of this method of cutting the material is associated with the loss of warranty.The angle grinder during operation and cutting produces very large amounts of heat, which in turn damages the edges of the sheet, as well as the coating covering it. In addition, the filings extracting during operation blend into the surface of the blades, additionally creating potential corrosion outbreaks.The right way of cutting sheet metal is to use automatic jumps (so -called Nilerler) or hand scissors. They use the mechanical force to cut the sheet, without exposing it to high temperature jumps. In addition, it is worth remembering that after cutting it is good to train cut places with dedicated protective varnish or special paint.

Does the roof require maintenance?

Yes, each roof requires periodic inspections to check if there have been any damage. Most of the products offered by Blachy Pruszyński have various types of specialized coatings available (covered by the warranty), increasing the life and durability of sheet metal. Maintenance consists mainly in removing the deposits and chimney dust, which left for a longer period of time can lead to sheet metal damage. Particular attention should be paid to places around chimneys that are sensitive due to more demanding operating conditions. If during the coverage inspection, local damage to the paint coating will be noticed, paint corrections should be made. In such a situation, the best solution is to use dedicated gloss paints tailored to a given coating. Such paints are in a stringent offer of Pruszyńska sheet and it is strongly recommended to use company products, recommended for a given coating.
