Fencing and similar light construction elements (posts, slabs, panels, footings, etc.) are manufactured using specific machines often referred to as "long or flat product machines" or "fencing machines".

These machines are also used to manufacture a wide range of other products, such as gratings for livestock farms, gutters, steps, stringers, sleepers...

The special feature of these machines is that they produce flat or long components on trays (or molds) of great length (3 to 6 m) and limited width (0.5 to 1.2 m). Most elements are produced by turning them over on trays, which is why these machines are also known as turn-over machines.

For thin components (sheets or panels) requiring a smooth appearance and high dimensional accuracy, the deferred demolding technique is used, and trays are...
