Russia is a country of central heating, with cities cut by heating mains. Due to the fact that the pipes are mostly underground, during repairs, abrasive impurities or even sand get into the coolant. With such water, aluminum batteries do not last long, and corrosion gradually begins to appear on the inner walls, which subsequently leads to leaks. The Italian manufacturer of radiators Global faced this when it came to our country in the 90s of the last century. To solve the problem of low-quality coolant, the company has developed bimetallic radiators, which are now known throughout the world.
Benefits of Global Bimetal Radiators
The peculiarity of these batteries is that they are made of two layers of different metal. The inner layer consists entirely of steel, which is more resistant to harmful impurities than aluminum. However, the outer layer is still made of aluminum, which perfectly removes heat. This design gives Global bimetal radiators superior performance.
- Heat carrier quality: >8,5 pH.
- Heat dissipation of one section: 175 W.
- Working pressure: 35 atmospheres.
- Pressurization pressure: 52 atmospheres.
The design of Global bimetallic radiators largely repeats aluminum batteries. The sections are curved so that the heat is evenly distributed around the perimeter, and the side slats provide additional heating efficiency.
In the manufacture of bimetallic devices at the plant, special attention is paid to each stage of production. For example, painting batteries takes place in several steps. First, the surface goes through 4 stages of pre-treatment, so that the paint fits better on the metal. Then the device is lowered into a bath of paint, after which it is fired in an oven and covered with a finishing enamel. Next, the device is re-fired, and then a second coat of paint is sprayed. Thus, the radiators retain their original appearance longer.
Comparison with Chinese radiators
Global bimetal radiators were the first on the market, and over time, other companies began to produce similar models, however, not all of them are of the same quality. For example, among Chinese batteries there are fakes. For such radiators, not the entire inner casing consists of steel, but only vertical collectors (pipes), while horizontal ones are made of aluminum. With such a design, the whole point of a bimetallic radiator is lost, because the coolant with impurities gradually destroying the metal passes through aluminum collectors and negatively affects them. Especially at the junction of steel and aluminum, since in this place the aluminum layer is usually several times thinner than in the collector itself. Such a device will fail much faster than the original full bimetallic radiator.
In addition, with Global instruments, the vertical pipes and the horizontal manifold are welded together, which ensures a 100% tight connection. For other radiators, it is possible to use a threaded or adhesive connection, which can lead to aluminum contact with water at the junction and further to through corrosion, since the aluminum layer is usually quite thin in this place.
Reliability
Thanks to this design and the use of special alloys created specifically for the production of batteries, Global bimetallic radiators last at least 25 years. Thanks to the control at each stage of production, the percentage of defects in the plant is less than 0,001%. The high quality of the Italian brand products is also confirmed by international and Russian certificates.
5 advantages of Global radiators
In the ranking among manufacturers of bimetallic radiators, the company’s products are in the top. What distinguishes the company’s products is the characteristics of the products. In addition to a pleasant design and high-quality painting, the technical characteristics of bimetallic radiators are very important.
- Resistance to low-quality coolant with a pH of 7–9,5 pH.
- Good heat dissipation, allowing you to quickly warm up the room.
- High working pressure and immunity to water hammer.
- Service life of at least 25 years.
- Competent design with various options of design and the sizes.
For all these indicators, we can say that the Global company produces the best bimetallic heating radiators for an apartment or house.

Global Product Reviews
In order not to be unfounded in the positive assessments of the company’s products, it is enough to read the reviews. Here are some of the positive ratings left by users.
Review. Global STYLE EXTRA 500 10 sections side connection RAN30I0VDKKM1U. Anas (25.09.2019) Advantages: It looks stylish, not bulky, and most importantly, high-quality workmanship. Disadvantages: Not yet. The radiator was just installed today. A comment: Today is the first night I sleep without a heating pad. Dubak was terrible. This radiator is top, it heats perfectly! Let’s see how it goes on in operation, while insanely happy!
Review: Global Style 500 – Quality warmth Alexandr 1987 31.03.2011 ADVANTAGES: Excellent heat dissipation, design, quality. LIMITATIONS: Not found. I have long wanted to change my cast-iron radiators to bimetallic ones. Although cast iron ones are famous for their heat dissipation, for some reason I didn’t notice it at all. And now, finally, the hands have reached. After consulting with my friend about the right choice of radiator regarding the area of the room and all the spare parts that are connected to it, we installed a six-section Global Style 500 radiator. It became really very warm in the room, and at the same time you can add or subtract it, as there are control valves. In winter, there is now absolutely no discomfort, plus excellent design and ergonomics that fit into the room. And I also want to add that as soon as the heating season ends, it is imperative to close the valves, as the water is drained from the risers and the radiator corrodes. I want to install the same radiator on the hall, only with an eight-section one, it’s very good as it has proven itself for me.
Ilya April 14, 2020 If heating radiators – then Global. Already made more than one apartment with them. Both at home and at the parents’, they recommended it to their friends. Still, the Italians have been on the market for a long time, well, taking into account the service life of this particular company in my environment … reliable. The style is universal. They heat super. What else do you need from radiators.
