Aluminum and zinc create a perfect harmony of steel with close proportions (55% aluminum, 43.4% zinc and 1.6% silicon alloy) and a silver flower appearance. As a result, the strength of the steel increases, the protective properties of the zinc and the stability of the aluminum create an extraordinary unity.
Aluzuk can be applied to many areas with its extremely durable structure. Besides being natural beauty, Aluzink is also respectful to the surroundings, is guaranteed for many years. At the same time, it has been proven itself against atmospheric corrosion which lasts for a quarter of a century.
Aluzinc's excellent corrosion protection is due to the cooperation of aluminum and zinc in the area of metallic coating. Protection is achieved by forming a layer of aluminum between the steel surface and the atmosphere. The aluminum barrier, ie the extremely durable aluminum oxide coating it contains, does not dissolve in many environmental conditions, providing long lasting protection against corrosion.
Zinc also in the Aluzink provides similar protection to the hot dip galvanized sheet. (for example, protection against situations such as the appearance of a possible cut and tear-off steel layer).
As a result of our continuous research and improvement work that we have done at test stations for over 20 years, Aluzink AZ185 (25-micron coating on double side) allows 20-year warranty if you do not experience the corrosion-resistant painting process due to corrosion
The cold rolled sheet, called FH, is obtained from the DKP after the rolling (thinning results of when the sheet is stretched from one side, pressing on the other side) physical and mechanical properties of the product.
In order to bring the FH grain (molecule) sizes and mechanical properties to the desired level, heat treated for 72-80 hours in annealing furnaces, thinned on low rate (5-10%) in order to gain final surface and mechanical properties and cold rolled sheet called CR is obtained.
CR is mostly traded in rolls,a product that can easily rust, on thinned at different thicknesses and not stored under appropriate conditions. Cold rolled products are not resistant to rust.Therefore, Galvanized coating of CR with metal material provides corrosion protection.As a result DKP is obtained. On xternal factors as long as it does not experience paint operation, ,its life is up to 10 years.
It is the processes; after the metal material suitable for painting is cleaned by various chemical processes along a continuous line and is made ready for the paint, in the line of the rollers contacting the metal surface, being painting with liquid organic paint, and after this process coil winding without interruption.
Hot dip galvanized coating material on the surface is coated with epoxy primer of 5 microns thickness by the direction of use and epoxy primer of 8 microns thickness on the inside. On the 5 micron external primer application as the last layer 20 to 25 micron polyester paint application is done. It is possible to apply film application to protect paint in transportation and production in both directions.
The paint system is chosen depending on the usage areas of painted Galvanized sheet products used in the production of Almetsan products. The most commonly used paint system is polyester. It is the name given to coloring 20 microns thick. It is a type of painting which is very common with economic, long life and optimum lifetime (30 years).
Trapezoidal section; Static calculations for the plate and suture beam roof closure system were made with Sap2000 v14.2 advanced program. The loading criteria used in the calculations are shown in the following images.
0 kg / m2 moving load is required for both thermal insulation foamand the lighting element if necessary. 10 x 0.61 = 6 kg / m rod load has been taken because the trapezoidal width in the bar approach is 61cm.
80 kg / m2 wind load is considered and the roof slope is taken 30 degrees.Pressure = (1.2 x Sina - 0.4) x q = (1.2 x Sin20 - 0.4) x 80 = 16 kg / m2 since the trapezoidal width is 61 cm in the bar approach, 16 x 0.61 = 10 kg / m bar load is taken.
In TS 498 loading areas of 75 kg / m2 5 kg is considered of as icing or density difference and it is taken as 80 kg / m2. In the bar approach, the trapezoidal width is 61 cm, so 80 x 0.61 = 50 kg / m bar load is taken.
