SUMMARY OF ALL EXPLANATIONS PROVIDED | ||||
---|---|---|---|---|
3 +4 | wired reinforcing mats |
|
wired reinforcing mats Explanation: I'd venture these are "alarmed reinforcing bar mats", or mats, the bars of which carry a detection current so as to trigger an alarm if someone cuts through a wall made of reinforced concrete. "Rebar mat" is the usual term for the mesh reinforcement in SRC. |
