I can't take pictures now. I built a brick building first, then cement and tiles. The color steel you are talking about is roofing material, and the early education with foam in the middle is higher, but the price without foam insulation is ok, which is cheaper than ceramic tiles. Bricks and tiles are the best, warm in winter and cool in summer, but the cost is high. Personally, I recommend you to use ceramic tiles, because cement is not corrosion-resistant, and the roof is insulated with colored steel tiles and covered with straw.
