Reinforcing made with a high degree of accuracy
We had a request from a customer to make a pair of reinforcing cages with a very high level of accuracy. This cage was made to +/-2mm (whereas +/-25mm is more the industry norm).
The bars were bent overlength, assembled into the complete unit and trimmed to the final dimensions. As you can see, the bar ends are beautifully lined up.
These were actually sent to a university laboratory where, instead of wooden shuttering, they were encased in clear perspex so the flow of the grout around such a dense structure could be observed.

Cage 1 – closeup showing accuracy of vertical bars. In fact, they are not all the same height, the ones nearest the camera are slightly taller than the ones farthest away. We made a jig of the correct profile to ensure the bars were trimmed consistently to the correct heights.
Cage 2 – generally much simpler than cage 1, but a number of the bars had to be cut off ‘mid-bend’
