Website newsEducation wrapped in steel
17 May 2022Education escorts us throughout our entire lives – as do the buildings in which we acquire our knowledge and skills. We recollect their architecture, interior design, pieces of furniture, and even their smells. Some have impressed us more than others, but none of them have left us indifferent. In our memories, these buildings are profoundly connected to our experiences and emotions, including the people we connected with there.Over the last few decades, education has evolved and so have the requirements for educational buildings. Architectural design has significantly increased in importance, technology has conquered interior design, and user comfort is a key concern, all of which are important factors accompanying the learning experience. Architecturally attractive buildings not only express the prestige and status of institutions but contribute to a sense of wellbeing for their users.

Technical information
Indaten® is a structural steel with improved resistance to atmospheric corrosion, forming a changing protective patina that evolves with the environment.
Dimensions: from 1.7 up to 80 mm thick; for thinner thicknesses: 0.5 to 2 mm thick
Mill finish for coils and sheets: pickled up to 7 mm thickness
Surface preparation: pickling and degreasing in order to obtain a finely grained patina
Coating: excellent adhesion of organic coating; the protective layer prevents rust propagation under the paint layer
Assembling: by welding or riveting and bolting with Indaten® or stainless steel parts
Welding: excellent weldability with all the usual welding processes.
Grades:
For Hot Rolled steel: Indaten® 355A & Indaten® 355D
For Heavy Plate: Indaten®355H
For Cold Rolled steel: Indaten® HC315WP
Recommendations: not to be exposed to condensation, repeated soiling, chlorine, or a marine atmosphere.
