Centering plates, also known as shuttering plates or formwork plates, are essential components in construction used to support and shape freshly poured concrete until it sets. These plates create a stable and uniform base, primarily for slabs, beams, columns, and other horizontal surfaces. Made from durable mild steel, centering plates are designed to bear heavy loads and ensure a smooth, level finish for concrete structures.

Each centering plate is typically fabricated as a flat sheet reinforced with welded stiffeners underneath to prevent bending or deformation under pressure. They are reusable, easy to handle, and available in standard sizes—commonly 600mm x 900mm or 600mm x 1200mm—allowing for quick assembly and dismantling on-site. Their modular design helps in covering large areas efficiently, reducing labor time and ensuring consistency across projects.
