It has been designed to optimize reduced spaces and to take advantage of the available surface. The industrial Alternating Tread Stairs help to create an open-plan space in an efficient and safe manner. Based on the American model, Lapeyre, it prioritises the verticality using shallow treads and eases going up and downstairs with packages.
These stairs are height-adjustable and can be installed perpendicular to the structure or parallel to it using a Stair Landing. They can also be located inside the structure by using a Beam for interior stairs.
This staircase allows to freely get around the ground floor without obstacles. It is available in security yellow colour and black.

Personalised phone or email service from our specialists
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: 30501, 30401, 31003, 31301, 31102
References that have this anchor: 30303-0
References that have this anchor: 30601, 30801
The minimum width is 29 3/8" and the maximum is 45 1/8". The length should be more than 51 1/8".
No, it can’t. This kit is specially designed to be used with our staircases.
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.
Yes, the direction of rotation can vary.
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:
Length: 92 1/2"
Width: 12 1/2"
Height: 12 1/4"
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.
You can do it yourself with the help of a friend. It is easily installed in a few hours, depending on the product.
TS8 Mezzanine: 3 hours with 2 people
TM15 Mezzanine: 4 hours with 2 people
TL30 Mezzanine: 5 hours with 3 people
The times are a guideline and for assembly only. You need to add the time it takes to measure up, move the components to the location, clean up, etc.
Once the product has left our facilities, the normal transport time is between 6 and 8 weeks. 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).
Depending on your order you can receive different packages: One box for the mezzanines of the S and M ranges or two boxes for L mezzanines.
Height: 21 1/4"
The stairs can share the box with the mezzanines if they are purchased at the same time or you can have a separate box for the stairs. Check the stairs section.
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 (86 lb), the rest of the ranges are considerably lighter (26.5 lb). The floor panels are very light and fit in any lift. No component is more than 94 1/2" long and therefore, fits in most lifts.
