Precast Ring 2*1

Precast concrete is a construction product produced by casting concrete in a reusable mold or "form" which is then cured in a controlled environment, transported to the construction site and maneuvered into place; examples include precast beams, and wall panels, floors, roofs, and piles.
A precast structure is a building system that uses prefabricated concrete components, such as walls, beams, and slabs, which are cast and cured off-site in a controlled environment. These factory-produced elements are then transported to the construction site and assembled into the final structure, resulting in faster construction, improved quality control, and reduced on-site labor compared to traditional on-site concrete pouring.
