Look! I-beams! Now this really gets me excited. When
pondering the colour of our structural steel, we decided a natural rust colour
would complement the spectacular red-yellow colour of the stone. We did some
research, asked a few steel experts and experimented. We took a steel flat
plate, cleaned it and treated it with acid. The acid started and accelerated
the rusting process. After a couple of weeks
when the rust colour was consistent we cleaned the sample with soda ash and
sealed it with a clear lacquer to stop any future rusting.
After a lengthy explanation, the steel subcontractor ordered
our steel columns and beams and started the treatment. It became important that
each individual steel piece is rusted and treated before assembly. Our patient
subcontractor waited more than a month before the colour was correct. Today
they started installation and I simply cannot stop smiling.
