Two male workers wearing work gloves and head coverings manually handle and stack fired red clay bricks atop a large outdoor pile at a brick kiln facility in the Al-Manaishi area, Al-Qanater Al-Khairiyah, Al-Qalyubia, Egypt. A tall smoking kiln chimney rises behind them against a partly cloudy blue sky, confirming active brick production on site. Brick kilns in Al-Qalyubia represent a significant segment of Egypt's traditional construction materials industry, supplying fired clay bricks widely used in residential and agricultural building across the Nile Delta region.
