Often, inside colums, it's necessary to install some support grids with the scope to support other internals like, for example, random packings or rings absuring 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 made in different size and materials and, when needed, with different lines of wire mesh applied on the grid's structure. These internals are generally made on the base of customer's design and drawings.
