A centering plate is a rigid metal plate used in construction and manufacturing for precise alignment and temporary support. The term primarily refers to a component of formwork for casting concrete, but it also applies to precision plates used for aligning machinery.

Function: They provide a stable, load-bearing surface for pouring concrete slabs and beams. They are a main support component in building canopies, reinforced concrete cement (RCC) casting, and other structural works. By preventing the concrete from leaking during solidification, they increase the overall strength of the cured slab.
