Qingdao Rikuker supplies light-steel houses, container units and apple cabins while also operating a substantial architectural doors-and-windows business. Its building-related offer can combine prefabricated structures with customized aluminum windows, doors, skylights and glazed openings for residential and commercial projects.

Buyers should treat the company as a mixed building-product supplier and define whether the required scope is a complete prefab unit, a light-steel shell or only façade openings.
