The corrugated tank system is the best and cheapest solution for storing clean water, rainwater, sewage, slurry, seawater.
The strength of the tank structure depends on the steel grade, profile type and construction of the bolt sets.
In our latest generation of tanks we have improved all the important features listed above. In cooperation with renowned manufacturers, we manufacture our S 350 GD steel tanks instead of the popular S 250 and S 280. The profile has been increased from 18 mm to 20 mm, making the tank much stiffer. The round shape of the tank provides additional structural strength.
All tensile strength calculations for the zawada.tech tanks are based on EN 1993 - 1 8 and EN 6773.
The tank profiles are connected by means of bolts, nuts and washers. The innovative design of the screw head and washers provides a much stronger connection.
Our new design, in which the screw head and washer are pressed into the same shape as the profile wave, guarantees a much more impressive connection.
This construction guarantees that one row of bolts is enough for the connections of many profiles. This significantly simplifies the assembly and provides huge savings related to labor costs. All screws are equipped with an ecological and rust resistant coating.
All our tanks undergo a galvanisation process - S350 GD steel is galvanized on both sides providing protection against rust.
The corrosion resistance of steel depends not only on the thickness of the coating, but also on its composition. Research carried out by scientists has shown that the addition of 3% Magnesium to the composition of the coating causes a significant increase in resistance to rust.
All our steel panels used to construct tanks have undergone the galvanisation process and obtained the Zinc - Magnesium - Aluminium coating.
This innovative alloy, which can be used in a galvanized steel process, is the next step in the evolution of the corrosion protection of thin steel sheets.
The thickness of the metallic coating can be significantly reduced, while at the same time increasing the corrosion protection thanks to the use of galvanisation technology with the Zinc - Magnesium coating.
The galvanizing method for our steel corrugated tanks is available only with us!
This is a unique coating that is applied as a second protective layer after the application of the patented Zinc-Magnesium coating.
The colored organic coating is applied immediately after electroplating. This guarantees excellent adhesion of the coating and a very uniform layer thickness of 55 μm.
A specially developed undercoat ensures excellent adhesion of the coating with a thickness of 50 μm.
The two-layer technology ensures very high cohesion between the layers and protects the sheet with the zinc-magnesium coating under extreme conditions.
The newly developed latest production line produces a special profile (76 x 20 mm) in 16 stages which provides extremely high strength and stiffness despite the thickness of the steel. The whole process is subjected to a special supervision.
At every stage of production, each element of the tank is checked in detail in terms of quality and compliance with the highest standards and standards.
