Simple self-supporting curved roof

The simple self-supporting curved roof system consists of a self-supporting profile that acts as a resistant element and watertight closure. This solution is used in canopies or in constructions that do not require thermal conditioning of the interior.

Multilayer self-supporting curved roof

The self-supporting curved roof system consists of two curved profiles: a self-supporting inner profile and a non-self-supporting outer profile that acts as a watertight closure. Both are fixed by means of a spacer profile, allowing the thermal insulation and the vapor barrier to be intercalated, which allows its use in sports halls, warehouses and logistics centers.

Simple curved roofing

The simple curved roof is a construction solution in which there is a supporting roof structure and where the curved metal profile performs the main function of enclosing the roof. It is a trapezoidal metal profile to which a series of equidistant inlays are made that give it the necessary curvature.

Multilayer curved roof

The multi-layer curved roof is a construction solution in which there is a supporting roof structure and where the curved metal profile performs the main function of enclosing the roof. This system adapts the roof to the most demanding thermal and acoustic requirements.

The self-supporting curved roof system is formed by a ribbed profile that acquires the necessary curvature through a series of transverse drawings. This curvature gives it a considerable improvement in its resistant capacity, being capable of doubling the separation between supports compared to the solution with the profile without curvature. The curved roof can be proposed using a simple solution, composed of a single corrugated profile, or a multi-layer, composed of an external covering corrugated profile, an internal support corrugated profile and intermediate insulation. The simple curved roof solution is made up of a self-supporting ribbed profile that serves as both a sealing element and support for the actions to which it is subjected. Its use is limited to canopies or closed spaces without the need for thermal or acoustic conditioning. The multi-layer curved roof solution is made up of a corrugated outer covering profile, which serves as a sealing element, and a corrugated internal support profile, which performs the resistant function against external actions and the self-weight of the rest of the components. of the cover: vapor barrier, thermal-acoustic insulation, separator profile and ribbed covering profile. This solution is used in closed spaces with thermal or acoustic conditioning needs.

The main structure, formed by frames spaced between 6-22 m, is responsible for supporting the main actions of the roof, guaranteeing its integrity and stability.
Horizontal suspenders and stabilizers support the horizontal reactions of the arch and limit the displacements of beams and supports.
The interior support profile constitutes the first layer of the roof enclosure and is placed and fixed on the main structure. This element supports both the own weight of the other components and the loads acting on the cover, meeting the corresponding mechanical requirements.
The vapor barrier regulates vapor diffusion to prevent condensation and protect the insulation, thus improving energy efficiency and interior comfort.
The separator profile, composed of Z-type profiles, is arranged on the interior support profile, fulfilling a double function: it provides space for insulation and allows the fixation of the exterior cladding profile.
Thermal insulation, mainly rock wool, contributes significantly to energy savings and improves thermal and acoustic comfort inside the building.
The exterior cladding profile constitutes the last layer of the roof enclosure and is placed and fixed on the separator profile. Its main function is to ensure watertightness and proper drainage of the roof.

Packaging and transportation: The curved roof profiles are grouped in strapped packages of 10-25 sheets, with a maximum length depending on the type of profile and a maximum weight of 1,500 kg. Each package includes an identification label with details of the manufactured product, order and destination. Transportation is preferably carried out in a truck closed with a tarp to prevent the material from being exposed to the elements.
Reception and unloading: Before unloading, it is verified that the material matches the geometry and thickness specified in the project. Unloading is carried out with the appropriate lifting means, and preferably directly in the installation area, to minimize movements on site.
Storage and protection: On site, the packages are stored in a covered and ventilated area on inclined wooden sleepers and are protected from humidity with breathable tarps. Packages are not stacked more than three high and no other materials are placed on them.
Installation on the structure: The packages are placed on the main beams, close to the supports, ensuring that the structure can support their weight. They are oriented in the direction of installation and are placed manually, sheet by sheet, under the supervision of the Construction Management. In the case of large pieces, the sheets are individually lifted from the ground to their position on the roof.

Our curved profiles allow the coverage of spaces in a light, efficient and aesthetic way.

The use of the self-supporting curved roof solution allows the design of simple or multi-layer roof systems without the need for an intermediate structure, for separations between supports from 6 to 22 meters. This solution allows for quick execution of the roof, eliminating the cost and visual impact of straps and generating a cleaner interior image. In the case of roofs open to the outside, simple solutions with a single profile will be chosen; and in the case of closed buildings, by multilayer solutions to incorporate thermal insulation.
