A Spiral Making Machine is a crucial tool in construction, particularly in reinforcing concrete structures. This specialized machine is designed to bend metal rods, commonly known as rebar, into spiral shapes. Rebar is utilized to fortify concrete, ensuring the strength and durability of structures such as buildings and bridges. The spiral configuration enhances the load-bearing capacity and resilience of the construction, especially in seismic-prone regions.

Engineering marvels and facilities that are constructed or installed in and around the ocean are marine structures. These structures can be fixed or movable or they can also be complementary structures. It can be done for the continuous development of marine resources.
