STAIRCASE CONSTRUCTION TYPES
Stairs
Concrete poured steps are the stairs in itself. However their look is far from esthetic and to improve their usability we cover them using the materials of different kind. The natural wood is most common, less often we can use the ceramic tiles, stone or flooring panels.
Wood is the general-purpose material. Its ease of processing is the grat advantage. Wood is warm and "eye frendly". It easiliy matches to the other components of the interior design.
Thanks to the CNC technology wood can be precisely processed and fitted to the other components of the project. Wood properties enable to obtain the desired structure and color.
Contrary to the other methods of covering the conrete poured steps, wood can be preserved and renovated.
STRINGER TYPE (STEPS-ON-STRINGERS) CONSTRUCTION TYPE
In contradistinction to classical stringer-type stairs, in this construction treads are not inserted into the stringers but are mounted on top of them. The stringers have the "comb"-like cutted nests where the treads are attached.
STRINGER TYPE (MIXED)
This concept is the combination of the two above explained methods. The steps are mounted into the internal stringer (wall side) and attached on top of the external stringer (balustrade side).
A very aesthetic and common solution. Stable.
CENTRAL-POLE TYPE
The solution is quite rare, mostly because of the steps shape. Each step is narrower on one side than the other. Treads are circularly inserted into the central supporting pillar. The balustrade is mounted on the external side (around the circumference) in order to increase the stability. Each tread is supported by the central pillar on one side and by the balustrade holder on the other.
Walking the spiral stairs is not comfortable. The staircaise does not occupy the space ergonomically.
SHELF TYPE
Modern approach but not widely used. Shelf type stairs should be planned on the early stage of the building construction. The construction part is hidden into the wall underneath the plaster. Only the flat bars are visible and serve as the support for the steps. The final effect can be improved by adding a glass balustrade or even without a balustrade at all.
PIN TYPE
The construction is optically light and more subtle than using the stringers. Its quite popular but sometimes less stable. The type of the material of which the walls have been built of is significant to apply this solution. Supporting pins must be mounted deeply into the wall, therefore eg. porotherm-type bricks can make this technique impossible. The stairs can be unstable and may become squeaky and loose over the years. This can be avoided by using the external stringer. An extra stringer will also increase the stability in most cases.
PIN-STRINGER TYPE
This approach mixes two above described styles. From the external side (next to the wall) the tread is attached to the nests cutted into the stringer whereas the internal side of the tread is attached by using the pin. The final effect is light, stable and esthetic which results in popularity of this technique.
DIVERSITY OF THE MATERIALS
The stairs does not only have the utility function in the household area. They serve also as a decorative element which has the infulence to the overall appearance of the interior./p>
The selection of the appropriate materials and the correct stair type results in functionality and safety of the given construction as well as in the comfort of walking up and down the stairs.
The large variety of different materials available in our offer, the professional advice and service are able to meet the highest requirements of our clients.
Timber
Wood is one of the oldest material that had been using in construction. It is durable, ecological and what is the most important it is "human-friendly". The possibility of using different types of timber gives a large variety of solutions and makes each project unique and unrepeatable.
We are always willing to ensure our clients that the quality the final product is finest. Therefore we purchase the lumber only from trusted suppliers who care for the correct way of storing it. Thanks to the modern machinery, innovative way of the processing and the high precision of production our final products satisfy the customers over the years.
When selecting the timber type we must follow the few general rules, which are strictly related to the properties of the wood species:
wood hardness decides about its durability and mechanical resistance against such factors as squeeze, impacts or dents. When comparing various species of wood it is significant to distinguish between hard wood (oak, beech, ash) and the soft one (pine, spruce). The stairs made of the hard wood are more durable and usually it is hard to notice any significant signs of use over the years. Whereas the projects made of the soft timber are less costly but more damages-prone. Therefore such options should be applied only in infrequently attended places.
wood wear resistance this is the parameter that defines wood surface vulnerability to the damages caused by friction. Each wood species has different wear resistance. Generally, the harder the timber is the more resistant it is. The parameter can be imporved by applying protective preparations such as varnish, oil or wax.
| Class | Range in kG/cm2 | Hardness | Class |
|---|---|---|---|
| 1 | under 350 | very soft | asp, poplar, willow, spruce, fir, arolla pine |
| 2 | 350-500 | soft | pine, larch, sham, sbirch, alder, douglas-fir |
| 3 | 500-650 | Midium hard | elm, nut |
| 4 | 650-1000 | Hard Wood | red oak, ash, cherry, pear |
| 5 | 1000-1500 | Very Hard Wood | oak, beech, hornbeam, false acacia |
| 6 | powyżej 1500 | ard as a rock | ebony, coconut |
STEEL & GLASS
the devil’s in... the accessories!
Finishing the stairs should match the interior profile. Well thought out and matching accessories can cause the stairs to be the main decoration of the house. The glass and steel are the most common accessories. Such elements as rails or balusters are usually made of steel.
Balustrade apart from its basic function which is to make walking the stairs secure, can also be an elegant crowning for the entire stairs.
The components made of the stainless steel look very elegant and do not require costly renovation processes during the years of using.
Filling a balustrade with glass is always worth reconsidering especially if we intend to keep as much light in the room as possible. A transparent toughened glass does not make any visual barrier and fits to both traditional and modern interiors.
