Quality and

Metallurgica Alta Brianza S.p.A. was one of the first companies in the steel industry to be certified according to EN ISO 9001 and now EN ISO 9001:2015. The business organization is totally focused on quality and customer satisfaction, in full compliance with the procedures in the different stages of the business activity.

MAB has also implemented a series of accurate checks and controls on steels, as a guarantee of the total quality of the product. Random checks are constantly carried out on the finished products thanks to the equipped in-house laboratory.

A new-generation 600 KN Galdabini dynamometer is equipped with hydraulic vices and an automatic extensometer, which allows traction testing on samples up to 36 mm; for bigger dimensions, tensile tests are performed on proportional samples.

A high precision optical measuring device carries out measurements down to a micrometer on special sections bars, where rays, concavities, depth, parallelism and perpendicularity cannot be detected with traditional instruments.

Latest generation optical mobile spectrometer carries out chemical analysis on both incoming materials and finished products.

Circograph and Defectomat non-destructive tests analyze the depth of the defects and Magnatest ensures anti-mixing.


New investments for Metallurgica Alta Brianza SpA in terms of energy self-sufficiency. MAB looks with confidence to the construction of its solar power plants with particular attention to sustainability.

MAB focuses on clean energy by investing in a new photovoltaic system: 1250 panels (400 W each) will cover approximately 6,000 m2 of the 32,000 m2 of the production site in Lecco, viale Giacomo Brodolini. The new plant under development, which should be ready and operating within summer 2022, will be able to produce a quarter of the energy power that MAB annually needs and therefore 500 kWh of the 2,000 kWh needed.
