Steel

It is the most common. 
 

This iron-carbon alloy is known for its robustness and wear resistance. Generally speaking, it withstands high stress without deforming and can be stretched without breaking. 
 

It is easy to shape into sheets / plates. 
 

It is in this form that steel arrives at our workshop to manufacture our gratings. 
 

The steel commonly used by JK Technic is S235JR steel. 
 

Compliant with European standard EN 10025 for structural steel, this type of steel is widely used in metal construction, steelwork, civil engineering… 
 

Steel can be galvanized to extend the service life of metal structures in aggressive or weather-exposed environments.
