Mezzanines

What load do the mezzanines support?

The metallic Tecrostar mezzanines of the S, M and L ranges support a uniformly distributed load of 200 kg/m² (that means that you can place a 200 kg distributed load on each square meter). This is the live load for residential uses according to the international regulations. The total maximum load will be 200 kg by the square meters of the mezzanine.

The XL mezzanines support higher loads, 500 kg/m² (considered as medium storage) and their usage is more industrial. However, they can also have a domestic use when more resistance and rigidity is required. The bearing board included in the XL kits is thicker, more resistant and allows point loads (pallet truck, racks) as well. Ask Tecrostar the permissible values of these point loads.


What are the available colours and finishes for the mezzanines?

The steel pieces of the structures, railing posts and stringers of the stairs are available in:

  • Black and white. Available in stock without additional costs.

  • Any RAL monolayer colour. The personalized colour has an additional cost formed by two different parts: a unique and fixed cost of 95 € that is specified after adding the items to the cart, and a percentage cost that is specified in the price of each product when choosing RAL colour option.

The delivery time of the personalized colour option is longer than usual, so it is recommended to ask the Customer Service Department about the delivery times.

In both cases the paint is a lacquer with maximum adhesion applied by electrostatic process with polyester powder paint, suitable for outdoors.


Does the kit include the flooring boards?

Yes, it does. They are structural boards made of 18mm thick european radiata pine plywood. They have tongue-and-groove joints in their four sides.

Length: 2335 mm

Width: 610 mm

Thickness: 18 mm


Is the floor tailored? How does it fit to my dimensions?

The kit includes as many boards as needed to install the mezzanine in its maximum dimensions. To install the mezzanine in smaller dimensions, it is necessary to cut the boards as it is explained in the installation manual included in the mezzanine kit. Cutting the boards is really easy and all the required tools are available at our online store as well.


Is there any other alternative to the wooden floor?

No. Tecrostar does not have a different flooring alternative. However, it is possible to personalize the finish of the floor by adding some accessories on the boards (carpet, platform,...). Check our floor finishes in accessories section. If the customer installs a different floor from the boards provided, it is their responsibility to ensure the resistance of the full mezzanine, since the floor contributes to the stability of the whole.


Can I close the mezzanine with plasterboards?

Plasterboard is a low density material, so you can make a closing wall on top of the mezzanine. You can also close the lower part of the mezzanine when mezzanine is indoors. When this closing wall is made in mezzanines installed in the exterior, you should consult tecrostar, since lateral wind load can cause the structure needs stability kits.


Can I have two heights?

No, you can’t. At the moment, our mezzanines are available just for a single height although some customers install them on another existing mezzanine. In that case, the resistance of the existing one should be checked.


What load can support the beams if I hang something from them? (E.g. a punching bag)

It depends on the beam type, we need to calculate the corresponding surface load. For example, a secondary beam TM15 supports around 560 kg. You should take into account that if we apply additional loads, a part of the bearing capacity of the beam is being consumed.

If you have any doubt about important additional loads, contact our technical department.


Can I install a Tecrostar mezzanine outdoors?

Tecrostar products can be installed outdoors (exposed to the elements), provided that a series of special measures are taken during installation and that you carry out regular maintenance in order to ensure that the materials are in good condition. The recommendations are the following:

  1. The Tecrostar mezzanine flooring comprises moisture-resistant plywood structural panels. However, it is recommendable for the customer to apply waterproofing paint to the floor and exposed edges; this will be particularly effective for preventing water from penetrating and getting into the tongue and groove joints of the panels and affecting the edges.
  2. It is also recommendable to install the mezzanine with a slight slope (approximately 2%) to make it easier for water to run off and prevent it from accumulating. This incline can be achieved by installing levelling plates under the highest columns of the structure.
  3.  Similarly, all wooden components (wooden steps, cleats, etc.) should be treated with some type of water-resistant paint or varnish to prevent dampness from penetrating and cracking the material, thereby resulting in the loss of its mechanical and aesthetic features.
  4.  In addition, wooden components should undergo regular maintenance, the surface protection applied (varnish or paint) being checked to see it has not deteriorated and reapplying when necessary.
  5. The steel components are coated with paints suitable for outdoor use but as after one or two years the paint will probably need to be touched up in small areas like edges and corners that could show signs of rusting and loss of shine. It is recommendable to polish these areas to remove any rust and then apply the paint.
  6. If the mezzanine is going to be installed outdoors near the sea, the maintenance recommendations should be carried out more regularly, due to the greater corrosive power caused by the presence of salt and humidity.
  7. The aluminium handrail of the railings does not require special maintenance, as all of them undergo surface treatments to guarantee their performance outdoors (anodized silver, lacquered in black or with wood effect).
  8. The structure and its corresponding floor anchors and braces are designed to withstand the actions of the wind. DO NOT CLOSE OFF THE SIDES, as this results in greater horizontal forces not considered in the calculation.

Can the mezzanine be installed without columns or removing a column? Attached to walls

No, our mezzanines are sold with columns by default. We cannot guarantee the resistance of walls or corbels and the customer will be responsible if the product is modified in these cases.


What is the diameter of the columns and measurements of the bases?

S and M range

Can I install the mezzanine in a sloped floor?

Yes. Provided that the inclination is small, we can use a wedge under the mezzanine columns to level it. If the inclination is too small it might be not necessary at all and the slope might be imperceptible.


Can I install it in a room with trapezoidal or irregular walls?
Yes, you can, because the structure does not need to be in total contact with the wall.

You can adjust the structural floor, working around architectural barriers or irregular surfaces.

When the walls are irregular or when you want to work around a fixed object, the decking can be finished off against the wall

Can I install the mezzanine at a lower or higher height than indicated?

It is possible at lower height but it requires to cut the columns and drill again though. At higher height is not possible. The cut of the columns can be done by the customer or you can order Tecrostar to do it upon request for a quote.


Can it be installed as an extension to an existing mezzanine?

Yes. This is quite common and the results are very good. The telescopic system of the columns enables the height to be adjusted every 12 cm, so in the worst case scenario you will have a 6cm difference.


Can I install a mezzanine making modifications of it?

You can make aesthetic modifications, but any structural modification non approved by Tecrostar will be under customer’s responsibility.


Can the columns be installed moved to the corners?
Yes. The columns can be moved to the corners up to ¼ of the total length of the structure. This feature allows you to work around the walls, switches or furniture you have on site without compromising safety.

Can I add extra columns to distribute the weight?

Yes, you can. However, the maximum load capacity will be unaffected.
