Logotipo Estruturas

In this department we develop and execute structural projects divided into four distinct areas: metal structures to support civil construction, structures complementary to frame systems - architectural structures (railings, stairs, chimneys, gates and automation, etc.), construction of pre-made metal structures -manufactured for the construction and industry market, export area – production of industrial concept (several structures per project).

Through Laser Technology we can cut almost any contour or design of different metallic materials, with different thicknesses, with reduced times and impeccable cut quality, without burrs, with high precision. The cutting edges are smooth and the cut pieces ready for packaging without further treatment. Combined with laser technology, we also carry out cutting, bending, welding, surface treatment and thermo-lacquering services.
