How do I choose a staircase?

Stairs have different designs: straight, quarter-round or U, spiral and retractable (folding). First of all, consider the place where you are going to place the ladder (indoors or outdoors) and the use you are going to make of it to choose the most suitable option.

In modern staircase design of two methods

Straight staircase

Spiral staircase

It is used that for the design of this staircase model, much attention should be paid to the interior decoration.

In the design of the modern staircase in a straight form, we need more space compared to the spiral model, and in the spiral design type, more time is needed to design this indoor staircase model.

Where do you want to install the stairs?

The first aspect that makes you choose a ladder is where it will be installed

Inside

For the interior, you can choose the following: Wood - a durable option that adds warmth to the space and stands out for its decorative power. for metallic - very decorative and ideal for modern styles -; And for those who combine wood and metal.

Foreign

Structures that are located outside must be resistant to moisture, rain, UV radiation from the sun... For all these reasons, we recommend choosing an aluminum or stainless steel solution that is resistant to wear. influenced by the weather.

stairs depending on the available space

Ideal stairs if you have little space

stairs Snail:

They are characterized by their spiral design, because the steps rotate around an axis. The wider the staircase, the more accessible it will be, but since they are usually placed in places where there is little space, spiral stairs can be installed from a diameter of 1.20 meters.

stair Collapsible:

These are folding ladders for installation in an attic or storage room, when access is too small or insufficient to place a fixed ladder. They are designed to be accessible from the bottom up when the ladder is opened. It saves space because it does not occupy the space of the lower floor. The structure opens only when you need it. The rest of the time, the ladder is hidden and stored in the hatch.

direct space saving:

A ladder whose steps are deeper on one side than the other to ensure comfort when going up and down while maximizing the use of space.

Space is not a problem.

stairs Direct:

They are the most practical and practical. It is a staircase that goes up or down in a straight line, that is, a staircase with a straight section, without a landing as an interruption. Depending on the number of steps, a width of 90 cm and a length of 3 meters may be sufficient. From then on pay as much as you can.

stairs quarter turn or U shape:

A design that has a first section in a straight line and then a second section that turns in an L shape. Also, in the case of U-shaped stairs, it can have a third section. The recommended minimum diameter is 1.40 meters.

Interior staircase accessories

In order to give the final color to your staircase, you must choose a series of accessories, including the type of stairs, railings and materials that suit your style.

Types of stairs: wood (beech, pine or oak), glass, transparent or opaque glass, metal or steel, etc. There are also cantilever stairs (which are supported only by the structure but do not have additional railings or supports on the sides). It is recommended to use anti-slip materials to prevent falling on the stairs.
Railing: It is placed around the staircase to prevent falls and improve the safety of the stairs. With cable, fence or pipe. If you choose one of the cables, you can choose between different ways to cross them in different designs.
Security fences: block access to the stairs. They are indicated to protect children or pets from falling and restrict their access to certain rooms in the house.

You need to know the hole you have to put the ladder. for this:

Measure the height from the ground to the top floor.
Measure the length and width of the top hole.
Measure the space available on the starting floor.

There are some standard data for stairs that you should consider:

The ladder should allow free access to any door or window in the area where it is to be placed.
The standard height of the riser (the vertical part of each step, the height of the treads) is 18 cm.
The depth measurement of a footprint (where you step) is between 25 and 30 cm.
The size to consider is that 2 risers (the vertical part of each step, the height of the steps) + 1 tread (where you step) must add up to 64 cm.
The height of the fence should be 90 cm.
The ladder must be able to support a weight of at least 150 kg.
A straight staircase should not have more than 15 steps in a row, because it moves too far forward and takes up too much space in the room.

Once we know this essential data, it's time to calculate our particular staircase.

How many stairs do you need?

The number of steps is calculated by dividing the total height from the floor to the ceiling by the size of the riser. Keep in mind that a kit stair can have a variable riser for added flexibility.

For example: for a height of 2.80 meters (the height is between the lower floor and the upper floor where the staircase connects), we divide 280 cm (the calculation must be done with the height in centimeters) by 18 cm (which standard size is one riser) and the result is that 15 treads and 16 risers will be required (always rounded up).

How big will the floor of the stairs be?

Applying the rule we mentioned earlier, 2 risers (the vertical part of each step, the height of the steps) + 1 tread (the place where you step) should add up to 64 cm. We apply it to our stairs: 2 (risers) x 17.50 cm (what each riser measures) + 1 tread = 64 cm. He erased the footprint and the result is 29 cm.

How far does the staircase go?

The space where the ladder is going to move forward is decisive in choosing it. In addition to the required opening width, these two data are shown in the technical sheet of each staircase.
