characteristic features of products.
The foundation, made of steel supports, is a screw-type pillars, which are connected to a rigid grid using a grillage. The stability of such a foundation is formed from the reliability of each support. The hollow shaft is able to withstand significant pressure of horizontal and vertical types. In order to make it more durable, a weighting agent is used. The length of the hollow shaft is the same as the depth of the dense formation, which is below the freezing zone of the soil cover. The screw-shaped tip is a guarantee of easy immersion while maintaining a static position. Screwing the support into the ground is carried out by means of a screw.If conditions differ from standard, screw-type poles or similar products equipped with two blades can be used. More information about screw piles for the foundation can be obtained on the portal.
What does the price depend on?
The main parameter for determining the price is the size of the pile. This indicator, as well as the length of the support, is prescribed in the price list, where there is information about payment for activities along with installation. In addition, the following factors will affect the cost:
- Tip type.
The latter can be welded (a pre-cut blade is welded to the tip, which is at the bottom of the pipe). It can also be cast (in this case, the part is made in a special form, after which it is attached to the product). The first option is for standard soils, while the second is for hard soils.
- Corrosion protection.
They resort to the use of hot galvanizing (in case of an increase in the degree of acidity or moisture level) or epoxy primer-enamel (if the soil cover in the areas differs in the presence of the usual composition).
Scope of application.
The mass load on supports, which differ in size, varies from 1 to 50 tons. Because of this, screw piles are used for the construction of any objects (in particular, shopping centers, warehouses, piers, gazebos, verandas, multi-storey residential buildings, pedestrian bridges , greenhouses, stairs, railway platforms, etc.).
