Corrugated Metal Calculator
Calculate materials needed for corrugated metal roofing, siding, and construction projects. Estimate panel quantities, costs, and coverage area.
Step 1: Project Details
Corrugated Metal Tips
Standard corrugated metal panels are typically 26″ or 36″ wide (coverage width is less due to overlap). Always add 5-10% for waste, cuts, and errors.
Step 2: Material & Cost
Cost Estimation
Galvanized Steel: $20-40 per panel
Painted/Color: $25-50 per panel
Aluminum: $30-60 per panel
Fasteners: Add $0.50-1.00 per sq.ft.

Cost Breakdown
Cost Per Square Foot
Material Only: $1.63 per sq.ft.
With Fasteners: $1.85 per sq.ft.
Professional Installation: Add $3-8 per sq.ft.
Prices vary by region, gauge, and finish.
Technical Specifications
Standard Corrugated Panels
Coverage Width: 34″ (from 36″ panel)
Thickness: 29 gauge (0.014″)
Corrugation Depth: 2.67″
Span Capacity: Up to 5 ft. between supports
Fastener Spacing: 12-24″ along ribs
Installation Guidelines
Overlap: Minimum 1.5″ side lap, 6″ end lap
Fasteners: Use corrosion-resistant screws with neoprene washers
Underlayment: Required for roofing; felt or synthetic
Expansion: Allow 1/8″ gap per 10 ft. for thermal expansion
Material Comparison
Galvanized: Economical, zinc coating for rust protection
Galvalume: Better corrosion resistance, 4x life of galvanized
Painted: Aesthetic options, additional UV protection
Aluminum: Lightweight, excellent corrosion resistance
