Product Description – C+ Cold-Formed Profile

PROFILE-Z-C-Σ

C+ Profiles

Cold-formed construction profiles of the C+, and Σ+ types are a new addition to the Blachy Pruszyński Company’s product line, designed for customers seeking solutions with even greater load-bearing capacity.

Cold-rolled sections are a proven and effective structural solution. In addition to standard profiles— Z, C, and Σ—we also offer “+” profiles. Thanks to the use of a wider range of raw materials, as well as a modern and advanced production line, we are able to add additional profiling to the ends of the section—the so-called “whiskers.” The C+ profile, like the Sigma+, is designed for architects and developers who require enhanced load-bearing capacity. In particular, the C+ profile—whose versatile shape is based on the C-profile, which is highly regarded by our customers—offers the same perforation options and cross-section while simultaneously increasing its load-bearing capacity compared to the base version, thanks to its distinctive “whiskers.”

The wide range of strength properties of our profiles allows for the optimal selection of the required amount of material—we encourage you to explore our full line of cold-rolled profiles

The Pruszyński Company guarantees that each order will be fulfilled in the same color (shade). However, due to the complexity of the coating processes, differences in shades may occur between individual shipments; therefore, responsibility for color consistency is limited to a single shipment. When reordering sheets from a specific batch, please indicate on the order or inform your sales representative that this is a continuation of a previous order and provide a color sample. To ensure color consistency between sandwich panels and other elements, such as flashings, please order them from a single supplier.

Dimensional Tolerance

Due to the manufacturing process and the limitations of the selected raw material, the dimensions of the profiles have a narrow tolerance range. Please contact our sales and/or technical department if you require more detailed information.

Technical Information

Technical details and specifications of cold-formed sections of the C+ (C Plus) type. They are made of high-quality S350 GD or S390 GD steel (upon request). They feature a specially designed profile that, thanks to specific bends, offers increased load-bearing capacity, even when using thinner material.
NOTE: Due to the characteristic "whiskers" of the C+ profile, it is made of steel with a maximum thickness of 2.5 mm, unlike the C profile, which can be made of steel up to 3.5 mm thick.

Drilling Holes in Structural Sections

“C” and “C+” profiles enable quick and easy construction of industrial or commercial buildings. They are primarily assembled using screws. For this purpose, the profiles feature three types of holes (Table 1):

Recommendations

Shipping Recommendations

  • If you are picking up the goods with your own vehicle, the vehicle should have an open loading platform that allows for easy loading and unloading.
  • Galvanized and aluzinc-coated profiles must be protected from getting wet at all costs!

Storage Recommendations

  • Oiling and passivating galvanized sheet metal provides protection against white corrosion only during transport.
  • Structural steel stored in bundles must not be kept outdoors or in areas exposed to moisture and fluctuating temperatures. Zinc, aluzinc, and magnelis coatings—particularly those that have not yet been exposed to the elements and therefore lack a protective layer—are sensitive to water condensation when air circulation is limited (sheets stored in packaging). Special attention should be paid to unloading in winter conditions and storage in heated warehouses. Due to significant temperature differences between the sheets, water condenses.
  • Sheets that have become wet during transport or storage should be dried; then, place spacers between the profiles to allow for free air circulation. After drying, inspect the galvanized (zinc-aluminum) sections and coat them with a layer of preservative oil.
  • Sheets intended for long-term storage should be inspected and then coated with a layer of machine oil—this applies to galvanized and aluzinc sheets.
  • Failure to follow the above recommendations results in the relatively rapid formation (for galvanized and aluzinc sheets, this can take as little as a few days) of zinc corrosion —that is, white layers loosely attached to the substrate that do not provide protection against corrosion.
  • Coated sheets in their original factory packaging should not be stored for more than 3 weeks from the date of manufacture. After this time, the packaging must be opened, and the sheets must be separated with spacers that allow for free air circulation. The maximum storage period should not exceed 6 months from the date of manufacture, under penalty of voiding the Warranty.

Do you have any questions?

Does the roof need maintenance?
Yes, every roof requires periodic inspections to check for any damage. Most products offered by the Blachy Pruszyński Company are available with various types of specialized coatings (covered by Warranty) that increase the service life and durability of metal roofing. Maintenance mainly involves removing soot and chimney dust, which, if left for an extended period, can damage the metal sheeting. Particular attention should be paid to the areas around chimneys, which are critical due to more demanding operating conditions. If localized damage to the paint coating is noticed during an inspection of the roofing, touch-up painting should be performed. In such situations, the best solution is to use dedicated touch-up paints matched to the specific coating. The Blachy Pruszyński Company offers such paints as part of its regular product line, and it is strongly recommended to use the company’s products that are recommended for the specific coating.
Is it possible to install copper flashings on a steel roof?
Caution must be exercised when using copper, as copper oxides are highly corrosive and cause corrosion of other metals. For this reason, it must not be combined with other types of metals on buildings (copper reacts upon contact and causes electrolytic corrosion of other metals).
Can I use an angle grinder to cut sheets?
Modern roof coverings preclude the use of angle grinders for cutting. Using this method to cut the material will void the Warranty.
An angle grinder generates a great deal of heat during operation and cutting, which in turn damages the edges of the sheet metal as well as its protective coating. Additionally, the metal shavings produced during operation become embedded in the sheet metal’s surface, creating potential corrosion sites.
The proper way to cut sheet metal is to use automatic nibblers or hand shears. These tools use mechanical force to cut the sheet metal without exposing it to extreme temperature fluctuations. Additionally, it’s worth remembering that after cutting, it’s a good idea to protect the cut edges with a dedicated protective varnish or special paint.
Why are metal roof tiles recommended for renovating old roofs?
This is directly related to its light weight. In the case of old roofs, the roof trusses of renovated houses are often already somewhat worn down by time. Therefore, it is safer to use metal roof tiles, which weigh around 4.7 kg/m², rather than ceramic roof tiles, which are nearly ten times heavier. However, it’s always a good idea to have a specialist inspect the condition of the roof truss and confirm whether it requires renovation or replacement after all. In such cases, the safety of the building’s residents or employees, as well as the installation crew, is always the top priority. In most situations, however, the condition of the structure allows for the use of metal roof tiles without major issues, whereas the use of ceramic roof tiles would no longer be possible.
How can I advertise a product? Where can I find more information?
Complaints should be filed at the wholesale store where the purchase was made. If the wholesale store in question has closed (is no longer in business), the completed complaint form should be sent directly to Pruszyński Company at the following address: pruszynski@pruszynski.com.pl

A complaint form is available in the "Downloads / Forms" section or directly here: COMPLAINT FORM
How to register and how does the warranty work?
In order to register the warranty, download the warranty registration available in files for download / printing or directly:
Warranty registration and send it completed to the following address: guarantee@pruszynski.eu

The warranty begins to apply on the day of purchase of the goods. Registration of warranty is necessary to quickly identify the purchased batch of goods.
