In 2018, construction of the North-South Expressway in Algeria began. Since 2018, Shantui Jianyou has participated in the construction of more than 10 sets of SjHZS050E concrete mixing plants to provide customers with high-quality mixed concrete with uniform mixing and accurate proportioning.

Algeria's North-South Expressway is a major traffic artery that runs through Algeria's north-south direction. Its construction technology is the most difficult and the natural environment is the worst. The smooth opening of the South-North Expressway will greatly ease the traffic pressure on the north-south artery and will have a profound impact on the economic development along the route.
