Covers that guarantee the safety of users and the work in general, alternative materials have been sought for their manufacture. The objective is to achieve lasting solutions based on the criteria of decentralized manufacturing, with a minimum environmental impact and a minimum of labor for its manufacturing. The most common materials for manufacturing roofs for industrialized buildings are concrete and metal, but you can also find green roofs. Other alternative materials used to manufacture this component are zinc sheets, wood, compacted earth, bamboo and prefabricated ductile elements such as metal mesh. concrete covers These covers are made of concrete and can be built on site through the following processes Formwork process.

Roof framing. Foundry. Drying or hardening time. Finally the stripping. In this case, the material used can be mixed at the foundry site, then brought premixed or simply manufactured in a specialized plant. A roof made of concrete can have any shape, in fact it is USA Phone Number List possible to obtain a complete monolithic element. Another advantage of this material is that it requires minimal equipment compared to other methods. Metal covers These are used to cover large-scale works, without intermediate support. Metal covers do not have to support great weight or actions. The central structure is in the shape of a triangle which is also known as a horse or truss. It is a constructive support resource that works efficiently.



In this particular, the inclined bars are supported by compression and the horizontal bars supported by means of tension. For the metal roof construction system to function optimally, the nodes must be isostatic and the weight must be concentrated in those nodes. Vegetable covers The insulation of vegetal or green roofs is provided by a cover of earth and vegetation. They include plants on their surface that function as a decorative but also organic element. These covers regulate the environmental temperature, due to their natural oxygenation process. On the other hand, they stimulate the reduction of toxic gas emissions from the environment.
