Case 3: Exterior stairs, parallel to the mezzanine. You will need a stair landing.

Case 4: A different placement to our mezzanines.

Yes, provided that the height matches. All our stairs can be located in any of our structures. As the structures, the stairs are height-adjustable. We have several different types of stairs, to ensure the height compatibility with the selected mezzanine.

Can the stairs be placed outdoors?

Yes, our products can be installed outdoors, although you should bear in mind a series of special considerations and carry out maintenance of the material to guarantee that they are in good condition. See this section for more details

Can the stairs be anchored to a mezzanine or construction wall?

Yes. They can be installed on a surface that is not a Tecrostar surface. The customer must bear in mind that they are responsible for the strength of the joint and structure to which they are anchored.

What regulations do our stairs comply with?

What regulations do our stairs comply with?
In TecroStar there are different types of staircases: some for private use, usually located in small spaces, some for general use, wider and more comfortable, suitable for workplaces or commercial premises.
There are in place many regulations for staircases in the different countries in which TecroStar is present. Therefore, it is difficult to determine whether a staircase type complies with a particular normative.

Our stairs are designed by defining the general criteria for each type of staircase, so that these are well defined and checked against those in the regulations:

  • Usable width.
  • Rung tread and riser dimensions.
  • Permissible step and staircase loads.
  • Handrail heights.

However, some regulations also refer to very specific construction parameters and details, which must be interpreted by the customer.

  • Material of the step.
  • Railing and handrail design.
  • Type of riser.
  • Step nosing (or overlap between steps).
  • Ceiling height clearance.

There are very few international standards that cover the design of staircases, one of which is ISO 14122 "Safety of machinery. Permanent means of access to machinery and industrial installations", whose criteria are suitable for our category . For all other regulations, the general criteria should be verified, which can be easily compared with the data in the Technical Data Sheets. Further details can be obtained from TecroStar.

Defining the intended use of the staircase is basic in most standards. Staircases are generally classified as service or private stairs, as well as general or public use stairs, the latter being more demanding.

If you have a specific regulation that your staircase must comply with, you can ask us and we will try to help you in your decision.

How can I turn the stairs up to allow the transit underneath them?

The anchor that joins the stairs to the mezzanine can attach the stairs with 4 or 2 screws. If you choose the configuration of just 2 screws, the stairs can pivot. In any case, the stairs have the same resistance.

Can I vary the direction of rotation of the spiral stairs?

Yes, the direction of rotation can vary.

Can the angle of inclination be changed?

Each model of stairs has an inclination and it cannot be changed unless otherwise stated. You must choose the stairs that best suit your needs.

Can I add extra steps?

The stairs include the maximum number of steps that are required in their maximum heights. The more the height is reduced, the less steps will be installed. However, you can acquire additional steps as spare parts, the number of steps is designed according to the inclination of each staircase though. An excessive number of steps would reduce the going available for treading, specially important when going down.

Can the railing of the stairs be taken off?

Yes, the railing of both sides of the stairs is removable and, therefore, it can be taken off. However, Tecrostar recommends to install it for security and because they provide rigidity to the stairs as well. On the other hand, the stairs include the railing; it is not possible to acquire them without the railing.

What are the dimensions and the weight of the stairs package?

For the orders that include just the stairs, the dimensions of the package are:

Length: 235cm

Width: 32cm

Height: 31cm

The weight depends on the model of the stairs. Check the product sheet.

Can the spiral stairs be installed inside the mezzanine?

Yes. You will have to acquire the beam for interior stairs.

How much weight do the steps support?

Check the the table with the specifications of each staircase to get this information.

Can I buy the stairs with just one side of railing?

No, you can’t.
