The traditional frames, made of wood, may undergo changes caused by multiple factors: not perfect seasoning of basic materials, changes in microclimatic operating conditions and tensions that the canvas itself transfers to structure can cause considerable deformation of the frame, compromising the proper tension and consequently the conservation of the manufacture. Later, the wood must be protected from Xylophagia insects and fungi, which can destabilize its strength and that from the frame may be transferred to the canvas and paint layer, creating big conservation problems.
The use of the best available technology, such as applying aluminium, confers to the stretcher-frame Leonardo its own intrinsic characteristics, such as lightness, durability and nondeformability over the time. As can be seen in the various applications of the aluminium spread today, it is a material much more resistant to deformation and above all, in terms of acceptable conservation, it is absolutely inert among the traditional wood used for frames.
The internal structure, modular and stackable and therefore easily transportable in the place of exposure, and the simplicity of assembly makes it possible to install the frame on site by passing, especially for large-scale works, the annoying impediments related to narrow passages such as hallways and/or gateways. Thus the use of aluminium profiles results in a substantial saving on the total weight, especially for large frames; it is possible both for the lightweight of aluminium and for the thickness of the frame that does not exceed 2.5 cm, unlike the perimeter of a traditional frame which must have a superior thickness. This also allows an easier accommodation of anchoring systems fixed or mobile of the picture.
The savings on the material, its handing out and finally on the assembly allow us to contain the price of the stretcher-frame Leonardo, making it low cost comparing to traditional ones.
