The world of building gratings is certainly very vast and with a project for a railway or subway station, an airport or a square, there are many choices to make, yet specialized companies often resort to pressed grating.
What is it about?
The pressed grating (or press-locked grating) is the result of the interlocking overlap between the bearing bars and the connecting bars (or cross bars). The grafting is carried out by applying considerable pressure in order to obtain a homogeneous grid. Specifically: the bearing bars are arranged to be parallel to each other while the cross bars are inserted transversely in the notches of the bearing elements. A press fits the cross bars into the grooves, deforming them permanently.
What are the advantages of pressed gratings?
The permanent deformation undergone by the connecting bars entails the formation of an extremely solid and reliable, resistant and light mesh structure, in addition, the distribution of the weight is uniform.
The pressed grating is a versatile material and it adapts perfectly to any need of capacity: the meshes can be more or less thick depending on the uses.
Are there any variations?
We said above that the number of links can decrease or increase according to use, going from wider to very thick or “heel-proof” links. In case of special needs, the gratings can have a non-slip serration to ensure greater safety in work or public environments.
What material are they made of?
Pressed gratings can be made of steel and consequently treated using galvanizing or painting. Alternatively, they can be manufactured in stainless steel for applications where corrosion resistance, safety and longer life are essential. Depending on the sector, it is possible to choose the most suitable type of steel and the most suitable surface treatment.
In which areas can pressed grating be used?
Regardless of the applications, looks matter. In this case the aesthetical effect of pressed gratings is pleasant and elegant, which is why many companies choose it not only for the industry, but also for civil uses. Among the main uses, in addition to the world of industry and building projects for stations and airports, there are: safety stairs that comply with current regulations; basement windows; storm drains and wells for rain or washing water.
