Prefabricated staircases are an effective and economical solution for the rapid construction of staircases in residential buildings, civil and industrial buildings. Thanks to the high precision of production and quick assembly, there is a significant saving of time and labor on the construction site. We supply stair elements as stair arms, platforms or complete assemblies, taking the shape, dimensions and details are always adapted to a specific project.

We are able to design and manufacture practically any type of staircase – from straight shoulders, through curved staircases with landings to curvilinear ones (spins) solution.

Materials and construction

• Reinforced concrete slab parts rectangular shape with integrated degrees and, as needed, with landings.

• Concrete: typical C30/37 (according to project requirements / statics).

• Reinforcement: according to the static design for a specific load case.

• Surface finish: smooth mold impression (suitable as a base for paint, PVC, paving or stone); can be added upon request anti-slip element.

• Preparation for railings and installation: the possibility of incorporating anchoring elements for railings, possibly preparations for electrical installation.

Design variants

Straight stairs:

• with upper and lower landing

• with upper or lower landing

• without platform

Crooked / space stairs:

• shape L or U (left-handed / clockwise)

• stairs composed of floor or mezzanine landings and arms

• the possibility of folding several arms next to each other (according to space availability)

Curvilinear / spiral staircase:

• solutions for compact spaces or architecturally demanding projects (as specified)

Dimensions and parameters

The dimensions are always designed according to the project documentation - they are typically adjusted:

• step width and height, plate thickness, shoulder width

• platform length, number of degrees

• fire resistance, attractiveness, readiness for final tiling

Thanks to this variability, the staircase can be very well adapted to the specific spatial conditions of the building.

Use

• apartment buildings, family houses

• civil and public buildings (schools, administration, sports facilities)

• industrial and warehouse halls

• indoor and outdoor stairs (according to surfaces and details)

Implementation and assembly

• Installation is in progress by crane for ready storage according to assembly instructions / project documentation.

• The staircase can be placed on a prefabricated structure or connected to a monolith.

• After settling there is an element fully bearable and the staircase can be immediately used to access higher floors (increasing the safety and smoothness of construction).

• Installation can be coordinated at the same time as fitting ceilings or balconies.

Certification and quality

• Production takes place in a controlled quality process.

• Shape design, reinforcement and storage details are carried out according to the project documentation and the statics of the specific building.

• Fire resistance requirements can be addressed upon request, anti-slip, visual design and integrated elements for railings.

Solid and sandwich walls as well as foundation beams are prefabricated reinforced concrete elements designed for fast and accurate construction of ground structures in civil, residential, industrial and agricultural construction. Wall units can be designed as full reinforced concrete (bearing / not wearable) or as three-layer sandwich walls (carrier layer + heat insulation + outer protective layer). The foundation beams serve as horizontal load-bearing elements, which transfer the load to the substructure and form a stable foundation for the structural system of the building.

Materials and construction

Solid reinforced concrete walls:

• Monolithic nature of the prefab, high load capacity, stiffness and durability
• Suitable for covering halls, stiffening walls, dividers, fireproof / anti-dust walls, etc.

Sandwich walls:

• Three-layer composition: carrier layer + heat insulation + protective (facade) layer
• The layers are interconnected stainless steel special clips/anchors (minimization of thermal bridges, long life)
• Isolation: ordinary EPS or XPS according to project requirements

Foundation beams / thresholds:

• Bearing horizontal elements for skeleton structures, often as plain beams between footings/piles
• Depending on the project, they can also be with a sandwich solution (e.g. thermal partition at peripheral parts)

Dimensions and parameters (approximately according to the project)

• Foundation beams: length up to approx 18 m, width up to 60 cm, height up to 120 cm

• Wall panels: length usually up to approx 10 m (according to transport and assembly), thickness according to design, height by floor (approximately up to 3,3 m)

• Production is mostly atypical – shape, thickness, reinforcement, openings and details are designed individually according to statics and drawing documentation.

Implementation and assembly

• Assembly of parts is in progress by crane on the prepared structure (basics, feet, ceiling construction).

• Wall anchoring is usually solved using anchor plates, which after fitting each other boils, possibly other system elements according to the project.

• For beams/sills, anchoring is possible, e.g. already contact pins, anchor plates, possibly using system anchoring elements.

• Can be integrated into elements penetrations, installation box, embedded elements, locksmith products and special anchors / mounting elements (e.g. HTU, HTA as needed).

Use:

Wall panels:

• Cladding of halls and industrial buildings

• Stiffening skeleton walls, dividing and fire walls

• Basement walls, technological and operational objects

• Rapid construction of residential and civil buildings (bearing and non-bearing walls)

Foundation beams / thresholds:

• Load transfer between footings/piles

• Supporting structure for perimeter skins and internal stiffening walls

• Protective / anti-impact elements in operational and storage halls

• Peripheral elements of the structure with the possibility of thermal separation
