The Long L-shaped Adjustable Stairs is formed by two straight telescopic flights that are connected by a central landing with a 90 degrees bend. You can adjust both the run and the height to access Tecrostar structures of the L range, thanks to their versatile upper anchoring system and to the possibility of extending their first and second flights. They can also be used in different locations adapting to the desired height.
In addition, these stairs can be set up inside the mezzanine, using the beam for interior stairs, to increase the usable space and to avoid their extension beyond the mezzanine. They can be installed on any of their four sides as well, with left and right turn. The Long L-shaped stairs provide the same comfort as Long Straight Stairs but bring greater safety thanks to their central landing.

You can choose between several types of stairs:
Alternating tread stairs
The stairs can be placed in different positions, increasing the possible configurations
Case 1: Exterior stairs, perpendicular to the mezzanine.
Case 2: Interior stairs. You will need a beam for interior stairs.
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.
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. 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:
References that have this anchor: 30303, 30501, 30401, 31003, 31301, 31102, 35100, 35000, 34001, 30900
References that have this anchor: 35200, 35300
References that have this anchor: 30601, 30801
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.
En la mayoría de los casos sí es posible. Nosotros no realizamos ni instalaciones ni presupuestos, pero facilitamos el contacto de empresas de confianza para que el cliente se ponga en contacto con la misma.
Once the payment is received, the dispatch time will be 5 working days. Once the product has left our facilities, the normal transit time is from 7 to 10 working days. The transport time varies greatly and is difficult to control due to many factors: Place of delivery, local holidays, customs, etc.
If we cannot meet this delivery time, we will contact you.
Mezzanines are shipped in boxes by an external company in a lorry with a tail lift that enables the box to be unloaded to the ground (at street level at the customer’s address).
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.
In most cases, you can.
There is a slight difference with the rest of the ranges. In order to deliver mezzanines XL, the delivery location should be accessible to a truck/long trailer (maximum mass admitted up to 36t). If there are access restrictions for this kind of trucks, there could be additional costs due to the necessity of transferring the merchandise to a smaller vehicle. Should you believe it exists 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 do not have back liftgate).
We deliver the product packed with pallets at the bottom, so its unloading should be made preferably with a forklift.
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.
