The raw material used to produce the interior stairs is the highest quality timber from different wood species: beech, oak, maple, cherry, acacia, walnut, ash. The wood should be well dried before processing. The raw timber is processed by high precision machines, obtaining initially lamellas or wood strips, followed by the elimination of significant defects such as knots, bark, cracks, rot. Then the staves are graded according to the color and texture, and, finally, using a water-based adhesive, the raw stairs and raisers are glued up
Further, sanding and forming machines are employed to bring the wooden boards to the desired dimensions. The finishing of the stair elements is done to improve the appearance and quality of the wooden surfaces. Lafor produces staircases, stairs, and raisers with standard or custom sizes, providing professional processing employing sophisticated equipment, such as CNC machines.
For stair finishing, water-based or polyurethane varnishes are used to provide high resistance to wear and also to physical or chemical agents. By finishing, the wood gains a pleasant aesthetic appearance and provides a longer service life. The color of a wooden staircase can be changed by staining so that it complements the interior design.
Wooden stairs are used in both public and residential spaces: villas, attic houses, duplex flats in blocks. There are several types of stairs: single or double, straight, curved, or spiral, with or without counter-steps, with or without the handrail, with or without a railing. The design of a staircase is chosen according to the space configuration (high, low, wide, narrow).
For example, a double stair is employed for vast entrance areas, and a single one, in small, minimalist spaces. The recommended height for one step is 18-20 cm, and this standard allows you to calculate the number of steps required for the interior in which you will install the stair. A right or L-shaped staircase fits well in small spaces. A curved stair may offer a feeling of elegance, but it is not a very practical choice. If children are included among the users of stairs, these stairs must be provided with additional security features to avoid possible accidents.
Concrete stairs are large, heavy, and overload the space also visually. The metal stairs offer the interiors a “cool” appearance and do not integrate into some design styles. Instead, wooden stairs are elegant, supple, flexible, and versatile, allowing access to narrow spaces or where no other variants are possible. Besides, wooden stairs provide the interiors a feeling of warmth and help create a welcoming and friendly atmosphere.
When installing a wooden staircase, most of the work is done in the factory, including some finishing stages, making assembly onsite less time-consuming. We must mention that by choosing wooden stairs, the costs of formwork and concrete casting are eliminated.
If you have chosen a concrete staircase, the concrete steps can be clad in wood, finally resulting in a durable ladder and a particularly pleasant appearance due to the applied wood.
