When you choose components for assembling the next order, a beautiful picture in the catalog is only half the battle. Real quality “comes out” already in the shop, when the part gets on the welding table. At rozavetrov.ua, we make ends so that the welder does not mention us with a “kind quiet word”, and the work goes smoothly.
Why is a rotary extractor a “cheat code” for a welder?
Most cheap ends on the market are the result of rough stamping. There, the metal is simply “squeezed out”, which makes it thinner on the radii and often has microcracks. We use rotary rolling. It’s like a potter’s work, only with AISI 304 stainless steel.
What does this give in practice:
Clean joint: Our ends have a clear cylindrical edge. This means that you don’t have to “catch” millimeters to weld the bottom to the pipe. The joint is tight, without gaps, which is critical for argon.
The metal does not “pull”: Since the deformation during rolling occurs gradually, there is no internal stress in the metal. When welding, the bottom does not “lead”, and your tank remains perfectly flat.
Thickness 1, 1.1, 1.5 and 2 mm: We did not choose these calibers by chance. For example, 1.1 mm is an ideal solution when units are not enough for rigidity, and 1.5 mm is already too heavy and expensive for the customer’s budget.
AISI 304: where does it “take out” and where not?
We use classic food-grade stainless steel. It is ideal for everything related to drinking water, alcohols, milk or weak acid solutions.
Important point: if you are making equipment for aggressive chemistry or very hot salt solutions, consult our technologists. But for 95% of tasks (from distillers to indirect heating boilers), AISI 304 is the “gold standard” that does not rust at the seams and retains a mirror shine for years.
Ellipse vs. flat lid: is it worth the candle game?
A flat bottom is cheap, but until the first serious pressure or water hammer. It “blows out”, the seam starts to crack, and the structure loses its appearance.
An elliptical bottom works like an arch in architecture:
It holds pressure many times better with the same thickness of metal.
Looks like a premium factory product, not a homemade one from a garage.
Makes it easier to drain residual liquid (especially important for food tanks).
Why buy from “Roza Vitrov”?
We don’t just resell — we understand how this metal behaves under a torch.
Edge control: We don’t send blanks with a “ragged” edge. Each end is finished.
Honest thickness: If it says 1.5 mm — it will be exactly a one-and-a-half-round, not 1.35 mm “with tolerance”.
Speed: We know what a “hot order” is, so popular items are always on the shelf, not “on order in a month”.
If you are looking for a reliable basis for your products that will not fail during pressure tests — you have found it. End from rozavetrov.ua — these are parts that are not ashamed of.
Aluminum and copper elliptical ends: professional solutions for special tasks
In addition to classic stainless steel, modern production often requires materials with specific physicochemical properties. The company "Roza Vitriv" offers the production of elliptical ends from aluminum and copper by the method of rotational drawing. These are components that combine complex geometric accuracy and unique characteristics of non-ferrous metals.
Aluminum ends: lightness and reliability (from 1.5 to 5 mm)
The use of aluminum in tank structures is due to its low weight and high corrosion resistance in specific environments. Our ends with a thickness of 1.5 mm to 5 mm are widely used in the automotive and aviation industries, as well as in the manufacture of fuel tanks for boats.
Advantages of aluminum ends from "Roza Vitriv":
High specific strength: Due to the elliptical shape and thickness of up to 5 mm, the part withstands significant vibration loads without the risk of cracks.
Perfect weld: Rotary knurling provides a clean, burr-free surface, which is critical for high-quality argon-arc welding (TIG/MIG).
No “springiness”: We control the drawing process so that the side of the part has a clear cylindrical shape for a tight fit in the shell.
Copper bottoms: aesthetics and exceptional thermal conductivity
Copper is the choice of professionals who create premium equipment. Copper elliptical bottoms with a thickness of 1.5 mm to 4 mm are indispensable in the production of stills, distillers and heat exchangers.
Why choose copper components:
Thermophysical properties: Copper heats up evenly, which prevents the product from burning inside the container.
Bactericidal: The natural properties of copper make it an ideal material for high-level food equipment.
Visual status: Copper products have an unrivaled appearance, which is important for design and craft projects.
Elliptical Tank Heads for Industrial Vessels: Stainless Steel, Aluminum, and Copper by Roza Vitriv Manufacturer
Elliptical stainless steel blades: the industry standard for quality and durability.
There are no small things in the manufacture of tanks, boilers and industrial equipment. Every weld, every detail of the body affects whether the structure will withstand pressure, whether corrosion will appear in places of metal stress and, ultimately, how much time the craftsman will spend on assembly.
The company "RozaVetrov"™ offers a professional solution for workshops and private craftsmen - elliptical bottoms made of AISI 304 stainless steel, manufactured by the rotational drawing method. These are components that turn an ordinary tank into reliable industrial equipment.

1.0 mm and 1.1 mm: The optimal choice for ventilation systems, decorative covers, lightweight water tanks or filter housings. These heads allow you to not overload the structure, while maintaining tightness.
1.5 mm: The most popular option for the food sector. Cheese dairies, home breweries, distilleries - here you need a balance between weight and strength. Steel of this thickness cooks perfectly and holds its shape when heated.
2.0 mm: “Heavy artillery”. Such heads are purchased for the manufacture of receivers, storage boilers and tanks operating under pressure or in conditions of constant vibrations.
Aluminum elliptical feet: Reliability in thicknesses from 1.5 to 5 mm
1.5 – 2.0 mm: The main choice for small containers, decorative elements and tanks for liquids without significant pressure. Lightness and aesthetics.
2.5 – 3.0 mm: The “gold standard” for fuel tanks of trucks, SUVs and boats. This is exactly the thickness that provides reliable penetration and resistance to road vibration.
4.0 – 5.0 mm: Heavy series for special tasks. These pipes are purchased for large expeditionary tanks, separators and power elements of special equipment, where maximum strength and a solid appearance are required.
Copper elliptical ends: impeccable aesthetics and thermal conductivity for premium products.
If stainless steel is pragmatism and aluminum is lightness, then copper is true art in metal. When your product should not only perform a technical function, but also look expensive, status-conscious, and professional, the choice is obvious.
At rozavetrov.ua we produce copper barrels with a thickness of 1.5 mm to 4 mm. This is a premium segment for those who create equipment for professional distilleries, elite cheese factories or designer interior elements.
Copper is more than just a metal
Why are experienced craftsmen willing to pay more for copper components?
♦ Thermal conductivity ¹1: Copper heats up instantly and evenly. This is critical for stills and mash tuns, where temperature control is critical to product quality.
♦ Natural antiseptic: Copper has unique antibacterial properties, making it indispensable in the premium food industry.
♦ Noble appearance: A product with a copper bottom becomes covered with an exquisite patina over time or shines with a mirror shine after polishing, emphasizing the high cost of the entire device.
The complexity of metal processing is our concern
Copper is very tricky: it is soft at the start, but instantly hardens under the roller.
To get a perfect ellipse without breaks and microcracks, we work at low speeds, controlling every movement of the tool. You get a tip with a perfect cylindrical edge, which is ideal for both argon welding and brazing.
