Lining of Santiago de Chile’s underground stations with vitreous enamel steel sheets incorporating a titanium dioxide-based catalyst.
Our construction subsidiary Ferrovial Construction is seeking to use vitreous enamel steel sheeting for lining Santiago de Chile’s underground stations. Such steel sheets are coated with a titanium dioxide-based catalyst which, upon reaction with light, triggers a chemical reaction which fixes NOx gases and converts them to (non-toxic) nitrates. In other words, this is a material which purifies the air with no energy consumption.
The following are amongst the environmental benefits of using vitreous enamel steel sheeting:
Removal of polluting substances in the air
No energy costs or added construction costs
Differentiating element versus the competition
The proposal stems from the knowledge that there are manufacturers of photocatalytic concrete in Spain offering their products as a means of reducing pollution.
