Euro Rib Panel Dimensions, Rib Spacing, Gauge Range, and Span Tables
Euro Rib Panel Dimensions, Rib Spacing and Span Tables
The Euro Rib panel is a trapezoidal metal roofing and wall cladding profile widely used in residential, agricultural, and light commercial construction. The profile features multiple shallow trapezoidal ribs designed to increase structural stiffness while maintaining wide sheet coverage and efficient water drainage.
Euro Rib panels are commonly used in:
• residential metal roofing
• agricultural buildings
• garages and workshops
• light commercial buildings
• sheds and storage buildings
• wall cladding systems
Euro Rib panels are typically manufactured using roll forming machines that shape steel coil into trapezoidal ribs through a series of forming stations. Because roll forming is a continuous process, sheets can be produced in custom lengths to match roof dimensions.
This guide provides a detailed technical overview of Euro Rib panel dimensions, rib spacing, steel gauges, coil width requirements, and span tables used by engineers, contractors, and manufacturers.
What is a Euro Rib Panel
A Euro Rib panel is a trapezoidal metal roofing sheet with multiple shallow ribs designed to improve structural stiffness compared with flat sheet metal.
Compared with traditional corrugated roofing sheets, Euro Rib panels offer:
• improved structural strength
• wider coverage width
• improved water drainage
• simple installation
• economical material usage
Because of these advantages, Euro Rib panels are commonly used in residential and light commercial metal roofing systems.

Industrial roofing
Thicker steel gauges provide improved strength and durability.
Euro Rib Panel Span Tables
Span tables determine the maximum distance the panel can span between structural supports.
Span capability depends on:
• steel thickness
• rib height
• roof slope
• wind loads
• snow loads
Typical span ranges include:
Gauge
Roof Span
29 gauge
2 – 3 ft
26 gauge
3 – 4 ft
24 gauge
4 – 6 ft
Engineering calculations should always be performed for specific building designs.
Coil Width Requirements for Euro Rib Panels
Steel coil must be slit to the correct width before entering the roll forming machine.
Typical coil widths include:
Panel Coverage
Coil Width
900 mm panel
1100 – 1150 mm coil
1000 mm panel
1200 – 1250 mm coil
Additional material is required to form the trapezoidal ribs during roll forming.
