The "A" extension of the structure includes two simple columns adjustable in height, the same as those of the initial module, which are placed at the end of the extension module. It has the same length-adjustable beams, although with one less secondary beam, as the last one of the previous module is used. It also includes the load-bearing floor of structural boards to cover the new surface.
Our product is totally detachable and reusable. Therefore, it can be considered as movable property. This feature, always depending on each country’s current legislation, allows its use and installation with no need for planning permission.
Tecro Space S.L. is not responsible of the use or inadequate installation of the product.
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 truck, there could be additional costs due to the necessity of transferring the merchandise to a smaller vehicle. 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.
Mezzanines and stairs are supplied with everything you need to install the kit at its maximum surface area or height.

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.
No. Mezzanines Online 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.
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.
It depends on the beam type, we need to calculate the corresponding surface load. For example, a secondary beam TM 15 supports around 1234 lb. 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.
MezzaninesOnline products can be installed outdoors (in the open), provided that the following considerations are taken into account, which define the structural, environmental and material maintenance calculation conditions.
Products with wooden components and load-bearing floors can be installed outdoors or in humid environments when a specific waterproofing treatment for wood is applied and maintenance is carried out on a regular basis.
It is not advisable to install products with electrical components outdoors.
If you want to install MezzaninesOnline products outdoors or in humid environments, we recommend you to request the waterproof treatment that provides additional protection to the steel parts, increasing their durability against those atmospheric conditions that can cause corrosion.
Outdoor installation involves forces due to snow and wind, which depend on the geographical location, altitude of the site, etc. These actions have been taken into account in the calculation, with certain maximum values that must be compared with those of the area where it is installed, to ensure that these limits are not exceeded.
The value of the snow load corresponding to the zone must be subtracted from the use overload supported by the mezzanine to the dimensions that have been installed. As a guide value, MezzaninesOnline structures can be considered to withstand a minimum use overload of 200 kg/m², and therefore the load of snow that a mezzanine can withstand outdoors is very high.
The mezzanine can be installed as a canopy outdoors by installing the stability kit, contemplating the case of a complete obstruction when it is placed against a façade, or free if it allows air to pass through its lower part. A wind speed of 100 km/h is taken as a reference. The regulations of each locality must be consulted to check that these limits are not exceeded.
Under no circumstances should the sides of the building be closed, as this implies greater horizontal forces that are not included in the calculation.
The columns of the mezzanine must be fixed to a solid base that resists the actions transmitted by the mezzanine. MezzaninesOnline offers guidance as to the type of footing or foundation required under the columns, but it is the customer's responsibility to check the final strength of the terrain.
When the mezzanine is required to be placed on a grass or soil type surface, some type of footing will be necessary. The modular foundation system shown below may be a good solution, although it is up to the client to check it through the technician responsible for the project https://piloedre.es/
The metallic steel pieces are lacquered with paints suitable for exteriors. MezzaninesOnline structures have a thermosetting polyester polymerised powder coating, with a coating thickness between 60 and 80 microns.
Corrosivity category C2 has been obtained, of medium durability, when submitting the pieces to the tests, according to the criteria of the European Norm EN ISO 12944 of May 1998: "Protection of steel structures against corrosion by means of protective painting systems". Examples of typical environments for corrosivity category C2:
● Interiors: buildings without heating where can be condensations (warehouses, sports centres,…)
● Outdoor: atmospheres with low pollution levels. Mostly, rural regions.
The medium durability of the lacquer covers a period of 5 to 15 years. The standard states that durability is NOT a "warranty period". Durability is a technical consideration that can help the owner establish a maintenance programme. That is, tests are performed for a specified number of hours under uniform conditions applied to smooth surfaces. The reality is that climatic and environmental conditions are very variable.
It is to be expected that after some time the structure requires retouches of painting on small zones, like edges or corners that can present beginning of oxidation and loss of the brightness. It is recommended to polish these areas to remove the rust and then apply the paint. The edges of steel parts are the parts most prone to corrosion and where rust first appears, in fact, these areas are not evaluated in salt spray tests, as the standard does not contemplate them.
MezzaninesOnline does not advise the use of metallic parts painted in white for exteriors, since the appearance of rust is appreciated much earlier than in black.
When the visual inspection indicates that paint retouching is required, careful attention should be paid to all edges or corners that may show signs of oxidation and loss of gloss. It is recommended to polish these areas to remove the rust and then apply the paint.
If the mezzanine is to be installed outdoors in a marine or coastal environment, maintenance recommendations should be carried out more frequently, due to the corrosive power produced by the existence of salt and moisture. Try to control the oxidation process to avoid further deterioration. In this case, it is recommended to polish the affected areas to remove the rust and then apply the paint.
The aluminium handrails of the rails do not require any special maintenance, as all of them are subjected to surface treatments that guarantee their outdoor performance (anodised silver, black lacquer or with a wood effect).
The load-bearing floor of MezzaninesOnline mezzanines consists of structural plywood panels. It is intended for indoor use in a humid or protected outdoor environment in accordance with EN 636-1-S. The customer must apply a lasur* or specific waterproofing treatment for wood to the floor and to the exposed edges, which protects the surface and prevents water from penetrating into the tongue and groove joints of the panels and affecting the edges.
Likewise, all wood pieces (steps, wooden strips, etc.) must be treated with some type of water-resistant paint or varnish to prevent moisture from penetrating and the material from cracking, and therefore losing its mechanical and aesthetic characteristics.
The wood pieces should also be maintained, checking that the applied surface protections (varnishes or paints) have not deteriorated, and treating them if necessary.
The presence of water in puddles or “ponds” on the mezzanine should be avoided. To that end, the mezzanine should be installed with a slight slope to facilitate the water evacuation and to avoid its accumulation (approximately 2%). This unevenness can be achieved by installing levelling plates under the highest pillars of the structure. Drains can also be created for the same purpose.
* It is a product for outdoor uses that is more appropriate than varnish because it offers a high resistance, does not create a layer on the surface it is applied, controls humidity, gives a waxy finish and provides a wide range of finishes.
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.
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.
Yes, you can because the structure does not to be in full contact with the wall. When the walls are irregular or when you want to work around a fixed object, the boards can be finished off against the wall. These factors must be taken into account:
The total board surface included with the mezzanines only covers the maximum surface area of the mezzanine floor. You can add panels to cover this additional surface.
Yes, it is possible to reduce the height but not to increase the maximum position.
To reduce the height of S and M mezzanines, you can ask the technical department for a type of short column. With their use the telescopic and adjustable system is maintained, but the maximum and minimum positions of the structure are reduced.
Depending on how short the mezzanine needs to be, the customer may have to make a simple cut on these columns.
To reduce the height of L and XL mezzanines, a special cut must be made. You can order this cut from Tecrostar and we will send you a personalized quotation.
Yes. This is quite common and the results are very good. The telescopic system of the columns enables the height to be adjusted every 4 3/4", so in the worst case scenario you will have a 2 3/8" difference.
You can make aesthetic modifications, but any structural modification non approved by Mezzanines Oniline will be under customer’s responsibility.
Yes. The columns can be moved to the corners up to 1/5 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.
Yes, you can. However, the maximum load capacity will be unaffected.
At least two adults are required to install mezzanines, (they do not need to be DIY professionals). It is recommended to use safety equipment such as gloves, boots, etc., to avoid any accidents.
For the mezzanine floors in the L and XL range, a scaffolding or ladder system may be required for work at height and manual or electric lifting equipment for the primary beams, especially if the structure is over 3 m high. All other ranges are easily lifted by hand.
You will need the following tools to install the mezzanines: tape measure, a spanner set for nuts and bolts and a screwdriver (an electric screwdriver makes the job much easier), a spirit level, hammer, drill and a cutting tool for the board (handsaw, jigsaw, circular saw...).
You can do it yourself with the help of a friend. It is easily installed in a few hours, depending on the product. 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.
S Range: 4-6 hours with 2 people
M Range: 8-10 hours with 2 people
L Range: 15-22 hours with 2 people
XL Range: 25-28 hours with 2 people
The time required for fitting accessories (ladders, handrails...) could vary between 2-8 hours depending on the quantity, as well as the type/model of accessory.
At MezzaninesOnline, we offer four types of boxes that are carefully designed to adapt to and protect the products. Depending on the products in your order, you will receive one or the other.
Mezzanine floors in the S, M and L range are shipped in the same type of box. The S and M mezzanines require one crate for each shipment. The L range, however, normally requires two crates.
The XL mezzanines are shipped in two boxes; one for the wooden elements and one for the steel elements.
The rest of the products (stairs, handrails and other items) are shipped in smaller boxes.

Our logistics department packs the products with great care to optimise the space available inside the boxes. Sometimes, smaller products may share a box with mezzanines. In this way we make the most of the space and ensure that everything fits correctly.
No, you don’t. Our products are completely removable and reusable, therefore, they are considered as PERSONAL PROPERTY.
The mezzanines with an industrial usage require neither a building license for their assembly nor meeting the maximum constructed surface limits of the pavillion. As they are removable and hence personal property, they are subject to the same legal regime as the machinery, the racks, the vehicles, etc.
Sometimes, the carrier cannot access to point of delivery due to an extremely narrow street or any other difficulty. In such cases, the carrier cannot do the delivery with the usual truck and he may need to use a different vehicle or extra support.
If the carrier considers that the point of delivery is complicated, request a quotation. If you don’t inform in advance that the access is complicated, the delivery will be paralysed until you pay the extra cost.
MezzaninesOnline 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.

This connector is used to adapt the accessories to the primary beam of the Mezzanine XL. Thanks to this piece, the elements that are added to the mezzanine are fixed with greater solidity. The adapter can be used to include both the railing posts as well as to join the stairs and the stair landing to the primary beam.
The Stability Brace XL is an inclined bar that is placed in a column of the Mezzanines XL. It ensures the lateral stability in a determined side and direction.
It consists of a telescopic extensible bar that is joint to the column in its upper side. The bar is fixed to the floor at a distance of 51" from the column base plate removing, this way, the movement of the mezzanine in the side where it is installed.
The extension module "B" allows the extension of the mezzanine in the direction of the secondary beams, without the need to dismantle the existing mezzanine.
The extension modules have very similar load capacity, dimensions and usable area to those of the initial module.
