18J Cages
When it comes to securing massive structures, ordinary reinforcement isn’t enough. That’s where 18J Cages come in. Built with jumbo #18 rebar, these cages are specifically designed to handle the extreme loads and forces of large-scale infrastructure projects.
Unlike standard rebar cages, the #18J rebar has a slightly larger diameter, making it possible to thread and lock into place for anchor systems. This design ensures greater strength, durability, and long-term reliability.

What is an 18J Cage?
An 18J Cage is a heavy-duty anchor cage made from jumbo #18 rebar. The “J” stands for jumbo, meaning the rebar has a slightly larger diameter than standard #18, allowing it to be threaded and used in specialized anchoring systems.
What are 18J Cages used for?
They are primarily used in large-scale infrastructure projects such as transmission towers, utility poles, highway signage, and heavy industrial structures that require strong, stable foundations.
What standards do your cages meet?
All 18J Cages are manufactured to ASTM A615 Grade 75 standards, ensuring compliance with yield strength, tensile strength, and elongation requirements.
Can you customize cages for specific projects?
They are primarily used in large-scale infrastructure projects such as transmission towers, utility poles, highway signage, and heavy industrial structures that require strong, stable foundations.
