The drainage system is an important element of the roof, which provides collection, drainage of rain and melt water. It consists of standard parts: pipes, gutters, funnels, fittings and fittings. They are made from different materials and have a special configuration. This influences the formation of prices for drainage systems and their efficiency.
Plastic gutters
Structures made of plastic are very popular in the market. They are made from rigid or plasticized PVC with the addition of stabilizers. The first type of material is characterized by high strength, and the second is flexible. Rigid PVC gutter is suitable for large roofs where there are increased loads from rain and melt water.
The advantages of plastic systems:
- low cost: in the prices of companies, prices for plastic drainage systems start at 250 rubles. per running meter;
- ease of installation: the low weight of the main structural elements allows them to be installed without additional difficulties;
- ease of processing: plastic can be cut without problems using suitable tools;
- tightness: individual elements are connected to each other using special rubber clips. At the same time, the plastic does not deform during temperature changes;
- design: manufacturers offer gutter systems in 9 RAL shades;
- resistance to the negative effects of the environment: PVC does not change its appearance and properties under the influence of ultraviolet radiation, chemicals and serves for more than 50 years.
The disadvantages of plastic gutters include their low resistance to mechanical stress. Therefore, the instruction for such products prohibits use on high-rise buildings. PVC parts are not repairable. If any element is damaged, it must be replaced. This design requires periodic maintenance. Replacement of seals is also required.
Popular manufacturers of plastic drainage systems are called BRYZA (Briza), Galeko, Gamrat (Hamrat), Murol (Murol), Scala (Rock), Hunter (Storm, Regent, Maxi), Technonikol. They produce pipes and gutters of various diameters, external and internal corners, couplings. You can also find drain funnels, tees, inspection hatches, elbows, adapters.
Steel gutters
Systems formed of steel go on sale with a special protective coating - galvanized (made by cold or hot), polymer, painted. This extends the life of the elements and improves their aesthetic qualities. The advantages of such systems:
- strength: the structural elements of the drain are able to withstand heavy loads from wind and snow, therefore they are used in regions with a difficult climate;
- durability: the service life of a steel gutter reaches 10-35 years (depending on the manufacturer);
- a wide range of colors;
- lack of linear expansion under the influence of the temperature factor.
Steel elements are considered to be not resistant to corrosion. Therefore, if the protective coating is damaged, the material quickly deteriorates. Also, the disadvantages of this constructive solution include the large weight of all elements and the complexity of their installation.
The cost of steel drainage systems starts from 150 rubles. per running meter.Popular manufacturers of such products are called Vegastok, Galeko, Insi, Lindab (Lindab), NIKA (Nika), Ruukki (Ruukki).
Gutter systems made of other materials
Aluminum
Aluminum gutters are less popular, but they are not without advantages. They are lightweight and come in a variety of colors. Aluminum elements are not afraid of temperature changes, do not corrode and are easy to install. Their service life reaches 40 years. The disadvantage of such systems is called the small variability of shaped elements. Therefore, they are more suitable for structurally simple roofs.
The cost of aluminum gutters starts at 200 rubles. per running meter. Similar products are manufactured by Vegastock, Linkor, ALUTEC.
Copper
Copper is an expensive metal and is used to create exclusive drainage systems. They have only one color - natural, which darkens over time, becomes covered with a patina and acquires an emerald hue. Copper does not need additional protective coating and serves for several decades.
The disadvantage of the material is called its high cost (from 2500-3000 rubles per linear meter). For fastening copper elements, parts of the same metal are used. Popular representatives of such systems are Zambelli, Aquasystem.
Zinc-titanium
Mostly used on roofs made of the same material. The alloy is characterized by high strength, corrosion resistance and durability (service life is more than 100 years). The main disadvantage of a zinc-titanium drainage system is its high cost.
The cost per running meter starts from 500 rubles. A popular representative of zinc-titanium alloy gutters is Aquasystem.
Round and rectangular gutters
Circular systems considered traditional, they are found in buildings of any type: the private sector, small industrial facilities. This design is versatile due to the presence of free knees. At the same time, it is able to maintain an attractive appearance for a long time, does not lose its performance.
The advantage of round systems is that they are easy to install. Brackets are used to fix the gutters, all elements are connected to each other due to the presence of special grooves. To install pipes, holders are used, which should be located at several points along the entire length.
Elements with rectangular section are gaining great popularity in the market due to their original appearance. They are more expensive than traditional round options, but this is justified by the presence of modern design.
The disadvantage of rectangular systems is the relatively complex installation. Special rivets and sealants are used to connect individual elements. High-strength fasteners are used to fix the pipes to the building wall.
Main selection criteria
When buying a drainage system, first of all, they are guided by the existing type of roof, the expected load from melt and rainwater. The more complex the roof, the more precipitation is foreseen, the more powerful and durable the main structural elements should be.
When choosing a drain, its cost is also taken into account. With a minimum budget, you should not give preference to copper or zinc-titanium systems, which are the most expensive.
When buying drainage elements, they pay attention to their color scheme and configuration. Equally important is the presence of the necessary components and fasteners. They also take into account the peculiarities of installation and maintenance.
