Because bars are welded in a mat, the bars do not move when concrete is placed, insuring bars are in their proper position.
|
Since WWR is prefabricated and welded in plants, the risk of missing a bar is minimized.
|
The chance of improper bending of bars is reduced by using WWR since bending machines bend the mat as a single unit.
|
The use of WWR minimized the chance of misplacement since only one type of mat is used on a given section.
|
Provide the exact size of reinforcement where needed through variable bar size and spacing, thereby reduces steel waste.
|
Any wire size can be used from, starting at W 1.4 up to W 46.5 in increments of 0.1.
|
|
Faster erection time means you can beat changing weather conditions.
|
Removes reinforcement placement
from the critical path.
|
|
The material fabrication is automated.
|
With faster construction, insurance premiums are reduced. For example on bridge deck construction the barrier walls can be constructed faster reducing the time for fall exposure and reducing insurance premium.
|
WWR can reduce construction time, thereby saving: Crane rental time
Equipment leasing Increasing bonus
|
Lower material cost because not fabricating small bar. For example, for a #3 bar the cost is $5/ 100 wt. while a #6 bar is $1.25/ 100 wt.
