Expanding process

Expanding process

Expanded mesh is the result of cutting and cold-pressing the raw materials (rolls or sheets). All the expanding machines we use have been designed and built in-house. We constantly optimise these to ensure the excellent design and quality of our semi-finished products, plus great flexibility when producing mesh to order.

How expanded mesh is made

The shape of the blades used to cut the sheet metal determines the shape and size of the expanded mesh. The semi-finished product has a continuous, robust structure thanks to the absence of seams. The blades are tools machined from materials of elevated hardness, capable of making a clean cut even in metals up to 5 mm thick.

Zero scrap

Our expansion process produces no waste. This makes for efficient use of the raw materials and excellent output levels, hence our attractive prices.

A wide range of expanded mesh and micromesh

Thanks to its own blade production technology, Italfim offers one of the widest assortments of expanded mesh sheets in the world. The range of the smallest mesh – "micromesh" – starts from 50 micron DL (long way) and with an inscribed hole of xx mm. The largest Italfilm mesh has 100 mm DL.

Expandable materials

Many raw materials are suited to expansion by deep pressing: carbon steel, galvanised carbon steel, stainless steel, aluminium, copper, brass, titanium, other metal alloys and non-metallic materials. The choice of material depends on the intended use of the final product.

Formats available

Some types of expanded mesh are rolled and come in rolls of different height. The stiffest mesh is available in flat sheets. The formats and standard dimensions available for every type of mesh are indicated in the Products section. Rolls and sheets can be cut to measure on request.
