The product is ideal for large industrial investments. For their production, steel with a strength of 1860 MPa or, for example, 2160 MPa, is used. The high concrete class C 40/50 is also required, therefore the finished prefabricated element gains a number of unique properties: strength up to 40 kN, spans up to 28 m, better sound insulation and resistance to weather conditions. The offer includes channel slabs with REI 240 fire resistance. This type of ceiling is used in small and large single-family houses, multi-storey apartment blocks, semi-detached houses and terraced houses.

Features

• quick montage
• low cost of the ceiling
• very large spans up to 26 m
• no stamping
• lack of concrete overlay
• good sound insulation
• r different bottom surface

Application

SBN prestressed concrete lintels are characterized by high functionality and easy assembly. They are used as elements for closing window and door openings in wall structures, also in the case of vaults, openings in door partition walls. SBN lintels eliminate the need to pour the beams, which significantly speeds up the construction process.

Ring beams (shuttering blocks) are an element system in the formwork of a lowered rim. It includes elements that enable one-sided and two-sided support of the ceiling on internal and external walls (L, C or U type). The use of fittings will eliminate additional construction works related to formwork, which facilitates and speeds up the work. Due to their uneven surface, they ensure even load distribution and improve the aesthetics of the wreath.
