Steel Bar Reinforcement Cages

Reinforcing steel bar cages, also called rebar cages, pile reinforcing cages, are circular mesh pads made of carbon steel bar by welding process into cage-shaped steel skeletons used in the pre-casting production of pits, covers and tunnels for reinforcement or to strengthen tendons of location bars. The pile cages are especailly used in oil industry for sub marine construction of oil conveying pipes projects. We supply steel bar pile cages with a variety of cage pitch, hoop diameter, wire numbers and length.

Reinforcing Cage Designs: The pre-welded rebar cages are supplied in piles, pads, columns and other shapes to meet specific uses. We have advanced high efficiency welding machine to produce high quality pile reinforcing mesh cages to meet specific requirements of the project needs.

Black Steel Rebar Cages for Pole Foundation
Welded Steel Bar Reinforcing Mesh Cages
Welded rebar cages and mats reinforcement can be supplied in black steel ranging from 8 inch to 60 inch diameter and the length can be 60 feet. The welded rebar reinforcement is used to replace the wire tied rebar reinforcing structure with its advantage. Welded rebar cage provide a rigid and strong structure with rebars maintaining in the correct locations during transportation and in practical use.

High-strength Pile Reinforcement Cages for Sea Projects
Spiral rebar cage is used to ensure the transverse force of the pile. Its density has a crucial role to prevent the pile case from cracking. Iron steel rebar cages designed using rebar with square rebar links spaced at 200mm centres, for underground sea projects.

Using of Main Rebar and Pile Cages:
A, Combine the main rebar first and then the pile cage, that is to say, butt weld the rebar of 9m length together to 9-27 meters and then use the pilemaster to longer pile cage.
B, Combine the pile cage and then the main rebar, first make the pile cage of 9m or 12m of standard. And then weld the short pile cages to longer pile cages.
C, To get the double rebar pile cages to improve work efficiency, normally we suggest welding the second bar after the pile cage is formed.
D, For the inner reinforcing bar, we supply the rebar bending machine to reinforcing the stirrup. Compare to weld rebar structure, the difference is the rebar ends do not bond together, hence easier to install.
