The stairs can be placed in different positions, increasing the possible configurations
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.
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
Yes. They can be installed on a surface that is not a Tecrostar surface.
Wall anchors for concrete or brick are used to fix staircases to walls made of these materials.
The customer must bear in mind that they are responsible for the strength of the joint and structure to which they are anchored.
If you need to anchor the stairs to a structure that is not a Tecrostar structure, see the following details about the anchors:
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:
However, some regulations also refer to very specific construction parameters and details, which must be interpreted by the customer.
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 https://www.tecrostar.com/easily-accessible-stairs . 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.
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.
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.
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.
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.
For the orders that include just the stairs, the dimensions of the package are:
The weight depends on the model of the stairs. Check the product sheet.
Yes. You will have to acquire the beam for interior stairs.
Check the the table with the specifications of each staircase to get this information.
No, you can’t.
To install Tecrostar mezzanines you need 2 adults (they do not need to be DIY experts). It is recommendable to use personal safety equipment like gloves, boots, etc. in order to avoid accidents.
When installing range L mezzanines you may need to use some type of scaffolding or ladder for working at heights and manual or electric lifting machinery to raise the primary beams, particularly if the structure is more than 3m high. The other ranges can be lifted easily by hand.
You will need the following tools to install the mezzanines: tape measure, some type of spanner for m10 and m8 bolts and a screwdriver (an electric screwdriver will make the task much easier), spirit level, drill and a tool for cutting the panels (saw, jigsaw, circular saw, etc.)
You can find all the tools required to assemble it and tested by Tecrostar in the tools section.
All the models are installed by following these steps:
Pre-assemble the structure on the floor in the desired area.
Raise the outer structure to the desired height
Finish assembling the structure and floor.
The mezzanine floors are packed and shipped by an external agency in a lorry provided with a lifting platform, so that the boxes can be unloaded on the ground. The order will be delivered at street level to the address specified by the customer.
If there are access restrictions, there could be additional costs due to the necessity of transferring the merchandise to a smaller vehicle.
In order to deliver mezzanines XL, the delivery location should be accessible to a truck/long trailer (maximum mass admitted up to 36t). Should you think there is any kind of restriction, please contact us. The customer should take care of the merchandise unloading process. That unloading should be made from the lateral sides of the truck (this kind of truck does not have a back liftgate). We deliver the product packed with pallets at the bottom, so its unloading should be made preferably with a forklift.
Don't be alarmed by the total weight of the product, the components are light and manageable, so you can move them easily and take them up in the lift.The heaviest components are the primary beams from the L Range (39 kg), the rest of the ranges are considerably lighter (12kg).The floor panels are very light and fit in any lift. No component is more than 2.4m long and therefore, fits in most lifts.
However, it is important to mention that in the case of the XL range, some components may be a little heavier.
Tecrostar products are manufactured with the most suitable materials for the proposed technical solutions, combining wood, steel and top quality aluminium.
TECRO has earned certification from the AEM, the federation of Spanish materials handling. We have also received a Gold Medal Award of Merit from the INPEX (Invention and New Product Exposition), the top award for innovation at the largest Invention Exposition in the USA.
