Advantages of prefabricated stairs
Speed of installation of prefabricated stairs
Prefabricated stairs are delivered as complete pieces ready for immediate installation. Installing an entire flight of stairs using a crane takes a few hours instead of the weeks needed for traditional construction. In addition, the elimination of formwork and reinforcement at the construction site significantly reduces labor. As a result, the installation of prefabricated stairs reduces construction time by 80%.
Precision of dimensions
Production in steel molds ensures dimensional accuracy of each step with a tolerance of +/- 3 mm. Identical height and depth of all steps in the run guarantees comfort and safety of use. In addition, the smooth surface of prefabricated concrete stairs does not require additional leveling. As a result, prefabricated concrete stairs are immediately ready for finishing.
Strength and load-bearing capacity of prefabricated stairs
The use of C35/45 grade concrete in prefabricated stairs ensures a load carrying capacity of 5.0 kN/m². Appropriate reinforcement with RB500W steel guarantees the transfer of dynamic loads without scratching. In addition, monolithic construction eliminates vibration and creaking during use. As a result, prefabricated stairs maintain their parameters for decades of use.
Fire resistance of the structure
Precast concrete stairs have a fire resistance class of REI120 as standard. The solid concrete structure provides an effective barrier to the spread of fire. Subsequently, the absence of combustible structural elements increases the safety of evacuation. Such resistance makes precast stairs ideal for escape routes.
Possibility of finishing prefabricated stairs
The smooth surface of finished concrete stairs provides an excellent base for various finishing materials. It is possible to cover with ceramic tiles, natural stone or carpet. In addition, precast outdoor stairs can have a textured anti-slip surface. Such versatility allows it to fit into any architectural concept.
Cost-effectiveness of the solution
The use of prefabricated stairs generates savings in the cost of labor and auxiliary materials. Elimination of system formwork, reinforcement and ready-mixed concrete reduces expenditures by 40-50%. In addition, the shorter execution time translates into faster commissioning of the building. As a result, the total cost of stair construction can be 30% lower.
Service life of prefabricated stairs
Precast concrete stairs are designed for a minimum of 100 years of use. The use of concrete with frost resistance class F150 guarantees resistance to weather conditions. In addition, the appropriate reinforcement cover of 40 mm protects the steel from corrosion. Thanks to these parameters, prefabricated stairs retain their properties throughout the life of the building.
Variety of types and configurations
The prefabrication system makes it possible to make stairs with any geometric parameters. There are single-run, double-run, interval or spiral stairs. Then it is possible to make prefabricated slope stairs for off-road applications. Such flexibility allows optimal adaptation to any architectural design.
