How to reach us

Prefabrication services

The organizational structure of HSJ S.A. includes the Special Production Department equipped with machinery, which includes a shot-blasting machine, a modern laser, a gas and plasma cutting machine and a press for bending. According to the customer's specifications and drawings, we supply components ready for assembly in any geometrical shapes. Through continuous development and improvement of cutting and welding methods, we are able to offer improved quality of the components made, thus reducing the waste of materials for the customers and improving the efficiency of their production.

We also have the appropriate permissions to carry out welding work which gives us the ability to perform complex jobs requiring combining elements by welding. The steels welded by the team of our specialists continuously maintain superior weld quality and ballistic properties. We can combine different grades and thicknesses of steel. Our specialists are very knowledgeable about the properties of special steels, which is why your production will become cost-effective and will have a low level of risk associated with the processing of the material, because we provide high surface quality, cutting precision and process flexibility when changing the profile of production ordered. Our cleaner machine allows for obtaining surface cleanliness in Class Sa 3.
