MONDO outdoor dismountable bleachers are designed and manufactured in accordance with IS0 9001 (Quality Management System), ISO 14001 (Environmental Management System) and OHSAS 18001 (Occupational Health Management System).
This product is custom made, designed specifically for each project. The MONDO outdoor dismountable bleacher design is adapted to the dimensions available in the sport facility, carrying out a layout on which all the determining parameters are defined (step distribution, stand access areas, side and front handrails, access and seating spaces, etc.).
Each section of the dismountable bleachers, manufactured mainly in steel, consists of several modules, each of them measuring 2,5 m.
Each module consists of the following basic elements:
All these elements can be simply and quickly assembled and do not require any screwed connections.
The structure of each row (1), see drawing above, consists of a steel frame, manufactured in cold-rolled steel required to support the load it will be submitted to. This structure supports the passageway. A non-slip 2 mm thick steel plate is placed on top of it. Each frame and seat rests upon two vertical steel structures (2), which transmit the stress load to the ground where the bleachers are placed. The frames are attached to the pillar with housings (3). The seats also rest on these legs, which are also housed like the frames in the housings added for this purpose. There is a bracing (4) on the inside of the structure, thus making sure the unit does not deform.
As described above, the dismountable bleacher is mainly manufactured in steel elements. All the elements that make up the dismountable bleacher structure are made of S235-JR structure steel. This type of steel is mainly applied in building structures. It presents no difficulty for hot welding. The whole steel structure will be protected against atmospheric agents by hot galvanized treatment. This treatment is carried out according to European Regulation UNE 37-501-88 and UNE 37-508-88. These Regulations specify the materials to be used as well as the characteristics, tests, etc. on the coating. It specify also the minimum values to have in mass and thickness for the galvanized coating. It contains zinc, which cathodically protects the iron and steel, preventing corrosion.
MONDO outdoor dismountable bleachers are a customized product, adjusted not only to space available but also to customer’s needs. Therefore, in order for MONDO technical office to study each project, drawings and plans of the sport facility should be provided to MONDO.
Several options could be done in addition in the design of every single project, in order to meet the customer’s final needs:
The MONDO Group has developed and installed more than 50 bleacher projects in the last 15 years all around the world. They have been used in several high level sport competitions such as the Olympic Games or the Basketball World Championships, Final Four Euroleague, etc.
