Staircase I. Narrow, with flat bottom through the centre.

This staircase is named after its load bearing structure. It is the staircase most suitable for exploitation as the stairs are independent of the surrounding area. This structure is anchored to the foundation and to the floor ceiling. The distance from the surrounding area (walls) is 3-5 cm, or the wall space can be separated by handrails. The 3-5 cm intervals from the ends of the treads ensure the clean surrounding walls during the exploitation and cleaning of staircase. Prerequisites necessary for this structure include ferroconcrete base and ferroconcrete floor. However, solid wood floorings are suitable as well, especially when the edges of flooring are covered with metal profiles of the specified size, depending on the size of the structure and its own weight, leaving the possibility of adapting this staircase in wooden buildings with wooden flooring. However, concrete basis for this construction is a must.

Staircase II. Narrow, with snipped bottom through the centre.

The staircase is named after its bearing structure. Staircase of this structure has a weaker holding power compared to other types of flights. However, when the centre of the stringer is fastened to the wall (at the landing), the staircase is strong enough. Since the construction is thin and gracious, it is often chosen for modern interiors. This type of structure is similar to the type I of stairs, because the stringer is designed in the centre of treads, and the gap of 3-5 centimetres is left from the steps to the wall. Since this structure is much lighter than the option I, it can be easily adapted in buildings with wooden flooring. As the structure consists of metal, reinforcement and concrete, it is more advantageous than a simple metal structure because there are no vibrations and deflection during the exploitation of staircase. When the stiffeners are selected of an appropriate geometrical composition and class, and the proper thickness, the service life of this staircase can be long enough.

Staircase III. Narrow, with snipped bottom along the wall.

This staircase is named after its load bearing structure. This structure of staircase is worth attention, because they represent console stairs and are cheaper. When the flight is painted in adequate quality wall paint colour, the structure becomes almost invisible. This structure of staircase is anchored to the wall and therefore their holding power is sufficiently big and stable. However, the prerequisite of this construction is a brick wall, or wood carcass wall of a good stable and reliable construction. Since the flight is attached to a wall, the base and floorings can be made of any lightweight construction (wood, cast slag, concrete, light blocks and other lightweight structures). Should you choose this structure, you must understand that treads are simply at the wall. Therefore, the walls should be painted, just like the flight, with water-resistant paint which is easy to wash and clean. A possible way to protect the wall against damage is framing it with details of the same type and colour like the wood, or thin wooden or metal stripes such as stainless steel or colour metal rims.

Staircase IV. Wide, with flat bottom.

This staircase is also named after its load bearing structure. The construction from the first glance resembles classic ferro concrete staircases. However, as in all of our products, the way of making ferroconcrete structures is the use of residual or removable metal formwork. Using 3D calculated and designed metal formwork, regular lines of flights are obtained, they are of correct geometric shape and have no errors. Since this type of flight is of heavy construction and heavy own weight, the necessary condition to it are masonry walls and reinforced concrete flooring. The structure is fastened to the wall, so depending on the width of flight, a strong foundation is not necessary. These stairs are suitable for exploitation, as well as the type III stairs (treads are close to the wall) and therefore during the exploitation of stairs the wall may get dirty. There are various options for protecting wall against damage (by framing, or painting with paint of the corresponding quality)

Staircase V. Wide, with snipped bottom.

Name of the stairs was also chosen by its bearing structure, like for all stairs. This type of stairs is produced and adapted as often as the type I flight. Since the construction is sufficiently stable, thin and gracious, it can be integrated between walls and in the available space, it is often selected for modern interiors. This structure is exploited in the same manner as other structures. If the flight is attached to the wall, the basis and flooring may be of lightweight construction. If the construction is design in space, then the concrete basis and ferroconcrete flooring are necessary. Since the construction is wide, various finishes can be used (wooden steps, stone steps, tile or carpet). Depending on the exploitation conditions and the effects on the construction, this type of structure is applied when there is no direct external effects – atmospheric effects. Since the construction has no longitudinal reinforcement and the holding power depends only on the metal and concrete class, the formwork is left in the structure. If this type of structure is required in outdoor conditions, it must have thin stainless steel moulds, metal stiffeners of the corresponding class, and concrete resistant to atmospheric effects.

Staircase VI. With one or two stringers (open or closed).

This staircase is named after its load bearing structure and technical types – open or closed. These types of staircase are typically used for the construction of stairs in lavish classical style interiors, public or residential premises. Stair finish, depending on the stair purpose, is optional (wooden steps, stone steps, tile, tarket, carpet). The bearing structure of stairs has a very large holding capacity, because it consists of three, and if necessary of four components having the holding power: fittings, concrete, metal formwork, and if necessary – stiffeners. Stairs of this construction (regardless of the walls) can be fitted simply in space, of course if the outer flights are attached to the wall. This type of construction consists of two stringers which simultaneously protect the walls from damage. Flights, depending on external effects, are painted with wall or ceiling paint of suitable quality, and if necessary, can be coated with metal type plaster and painted in metallic paint. The requirements for this type of staircase structure: ferroconcrete basis and ferroconcrete flooring, but if the staircase is installed between the brick walls, the flooring and base can be of lightweight structures.

Staircase VII. With ferroconcrete handrails (open or closed).

The name to this staircase was attributed according to the main load-bearing element of the staircase – the handrail. This type of stairs is similar to the type VII. Stairs finish also can be of any type. The staircase can be used for various purposes (in space, by attaching closely to one wall or installing between the walls). Since the bearing power of this construction depends also from the handrail, the load bearing power of this type of stairs is the largest among the stairs made in our company. Having in mind that load in public buildings can be much larger than the requirements of standards and the stairs are often very bulky, this structure would be most appropriate, and in addition the ferroconcrete banister will never break during operation even in very crowded conditions. This construction of stairs are chosen and adapted in various public or residential premises. Since the flight is whether ferroconcrete railing, we offer to cover the inside part of a rail with the plaster mirror band, and paint the stairs in black matte or semi-mat, as the mirror reflection of the band will make the more lively. However, we only recommend, while you should create and plan, and we are ready to fulfil all your realistic ideas.

Staircase VIII. Cantilever stairs.

The name of stairs was selected according to technical decision of construction – the console type of anchoring. Wooden treads of this structure are reinforced with metal, and according to the appropriate technology are mounted directly to the wall. Adaptation of the stairs for exploitation is not simple, it requires a robust and reliable brick wall. Cantilever staircase is adaptable in minimalistic interiors. If the stairs are on private residential premises, the customer or user often wishes to have stairs without a railing (it is unsafe, but nice). Cantilever staircase is intended for people who like minimalism, freedom, and a large home space. Cantilever staircase designed and produced in our company has more advantages, for instance we design and make a cantilever tread up to 1.1 m length, and 80-85 mm thick. The thickness of tread is quite low, but is bearing capacity is quite large and good enough to guarantee the operation and support capacity – it is the main advantage of the console stairs. (However, we have to admit that the console stairs are expensive compared with other structures of stairs).
