Inside the columns sometimes it is necessary to install grids which support other internals like, for example, random packings, ensuring the mechanical support but, at the same time, allowing the correct crossing of the grids by the gas flow without a big pressure drop.
These grates can be made in different sizes and materials and, when needed, with different lines of wire mesh applied on the grid structure. These internals are generally made according to the customer's design and drawings.
