Pre-fabricated stirrups, precisely bent by machine, reduce labor costs.
Pre-fabricated steel cages or Stirrups This is a new alternative that helps solve classic problems at construction sites: "wasting time bending rebar" and "uneven bending."“
Our products are manufactured from... RB6 and RB9 round steel bars. that meets the standards TIS It is passed through a high-precision CNC bending machine, ensuring that all bending angles are a perfect 90-degree angle and the hook bending distance meets engineering standards.
Why do modern contractors choose pre-fabricated steel stirrups from AY Contento?
- Save Labor & Time: No need to hire workers to sit and measure, cut, and bend each ring one by one. You can focus your time on tying the rebar and setting up the formwork instead. The work will be completed 2-3 times faster.
- Precision (Precise dimensions): No more problems with "crooked" or "oversized" casings that result in inconsistent concrete covering. Our casings are uniform in size, easy to install, and produce a neat finish.
- No Waste: Order the exact quantity you need; no need to waste scrap metal.
Applications
- Column Stirrups: Wrap the steel reinforcement around the column to resist shear forces and hold the steel reinforcement in place.
- Beam stirrups: Wrapped around steel beam supports, it withstands shear forces and increases the structural strength.
- Reinforcing bars/lintels: For brick wall construction.
- Pile driving work: Used as a sleeve to secure the core of drilled piles.

(Note: The casing size will be approximately 2.5 – 5 cm smaller than the actual column size to allow for concrete covering.)
Frequently Asked Questions (FAQ)
The simple formula is: Actual pole size - 5 cm.
For example, if the house pillar is 20x20 cm, order the size of the sleeve. 15x15 cm. Yes. (Please allow 2.5 cm of concrete cover on each side for the steel reinforcement.)
