1. What is R Panel Weight Calculation?

The R Panel weight calculation determines the total weight of metal roofing panels based on their area and weight per square foot, which varies by gauge (typically 0.85-1.08 lbs/sq ft).

2. How Does the Calculator Work?

The calculator uses the simple formula:

\[ Weight = Area \times Weight\_Per\_Sqft \]

Where:

Explanation: The calculation multiplies the total area by the weight per square foot to determine the total panel weight.

3. Importance of Weight Calculation

Details: Accurate weight calculation is crucial for structural support requirements, shipping logistics, and installation planning.

4. Using the Calculator

Tips: Enter area in square feet and select appropriate weight per square foot based on panel gauge. Standard R panels typically range from 0.85 to 1.08 lbs/sq ft.

5. Frequently Asked Questions (FAQ)

Q1: What affects R panel weight per square foot?
A: The primary factor is metal gauge - thicker gauges (lower numbers) weigh more per square foot.

Q2: How do I determine the weight per square foot?
A: Check manufacturer specifications for your specific panel gauge, or use standard values (22 gauge ≈ 1.08, 24 gauge ≈ 0.85 lbs/sq ft).

Q3: Does this include fasteners and trim?
A: No, this calculates only panel weight. Add 5-10% for fasteners and trim in total weight estimates.

Q4: Why is weight calculation important?
A: Proper weight estimation ensures structural integrity and helps determine if existing roof structures can support new panels.

Q5: How accurate is this calculation?
A: Very accurate for panel weight alone, but actual installed weight may vary slightly due to overlaps and installation factors.
