What type of tie is galvanized steel and fits into a slot formed in a concrete beam or column?

The correct answer identifies the corrugated tie, which is designed to fit into a slot formed in a concrete beam or column. Corrugated ties are utilized to provide support and connect structural elements together, especially in reinforcing the interactions between concrete components. Their design, featuring a corrugated shape, allows for better resistance to shear and tension forces, making them particularly effective in securing concrete structures.

Additionally, galvanized steel is commonly used for these ties due to its corrosion-resistant properties, ensuring longevity and durability in structural applications. The slot-forming aspect is what distinguishes them from other types, as it allows for a snug fit that enhances overall structural integrity.

Understanding the specific applications and benefits of different tie types is essential for contractors, as it affects the strength and stability of the structures being built or repaired.
