Concrete Rebar Calculator FAQ
일반적인 견적 및 계획 질문에 대한 명확한 답변.
Common residential slab rebar spacing is 12 inches on center in both directions. Heavy-load slabs may use tighter spacing like 8 or 10 inches.
Number 3 and number 4 rebar are most common for residential slabs. Number 5 and 6 bars are used for heavier structural applications.
Multiply total linear feet by the weight per foot for your bar size. For example, number 4 rebar weighs about 0.668 pounds per foot.
