Heavy metal carpentry

Heavy metal carpentry

Heavy metal carpentry includes all the workings in the iron metallurgical sector for making and producing finished metal products. In general, metal carpentry requires specific techniques and machines for cutting, welding, folding, deformation and finishing metals.

The companies that specialize in heavy metal carpentry, such as Mantiero Angelo Srl, are involved in large metal workings that need precise and innovative technologies.

How do you differentiate heavy carpentry from light carpentry?

Differences between heavy and light carpentry

Metal carpentry is divided into two categories: heavy carpentry and light carpentry. Heavy carpentry includes metal structures such as bridges, platforms, bearing structures and warehouses. Light carpentry includes smaller works such as stairs, trolleys, gates, boxes, etc.

Metal heavy carpentry: what are the most used metals

In the metal carpentry sector, the most used metals are the following:

  • iron and all iron alloys
  • steel
  • copper
  • zinc
  • brass


Steel is the most important material as it is a light and resistant iron and carbon alloy of a high quality.

When other noble metals, such as nickel, manganese, chromium, and copper, are added to steel, it gets other chemical and physical characteristics that make it suitable for structural carpentry workings. Moreover, steel is beautifully bright and polished and naturally non-corrodible, that means its chemical characteristics don’t change regardless external factors.


The king of metal carpentry is always iron, a metal that can’t be used in its pure form but must be added to other components and metals that strengthen both its resistance and duration. Iron is used for making bearing structures in the building sector. Iron is used to build sheds, prefabricated buildings, industrial platforms and civil structures of reinforced concrete where iron is used to increase the resistance and stability of the construction.

The importance of UNI EN 1090-1/ EN 1090-2 certifications

For the construction of structural steel works, companies must also obtain the UNI EN 1090-1 / EN 1090-2 certification, EXC1 and ECX2 execution classes. Actually, according to the law, from 1st July 2014, structural metal carpentry must comply with the UNI EN 1090-1 standard “Execution of steel and aluminum structures – Part 1: Requirements for the conformity assessment of structural components”.


This involves the implementation of the “CE” mark of the metal components in steel and aluminum produced in metal carpentry workshops. The UNI EN 1090-1 certification is related to the UNI EN 1090-2 standard “Execution of steel and aluminum structures – Part 2: Technical requirements for steel structures”.
