High tension m36 dome nut / dome nut for rock bolt
A post tension bar is a strong metal rod that is used in the construction of concrete structures such as bridges, buildings, and parking garages. Its advantage over traditional reinforcement is that it creates a compressive force within the concrete, which helps to counteract the tensile forces that the structure will experience over time. This can improve the strength, durability, and integrity of the concrete structure, making it more resistant to cracking, corrosion, and other forms of damage. Additionally, the use of post tension bars can help reduce the amount of material needed for a structure, making it lighter and more cost-effective.
