Construction
We support the structural fabrication of industrial facilities, buildings, bridges, towers, tanks and supports, a sector where plate cutting, oxy-fuel cutting, plasma cutting and welding are part of daily work. These projects require structural plates and steels with good mechanical strength, ductility and excellent weldability, to ensure safe joints and durable structures that meet code requirements. At NAT MAC we deliver plate and shapes cut to size through our CNC cutting services (oxy-fuel, plasma and waterjet), along with the structural steels, abrasion-resistant plate and consumables the job needs. We accompany every order with technical advice to select the right grade and thickness, so the fabricator receives material ready to assemble, with less waste and shorter lead times.
