27/111 Corrugated Panel Dimensions, Rib Spacing, Gauge Range, and Span Tables
27/111 Corrugated Panel Dimensions, Rib Spacing and Span Tables
27/111 Corrugated panels are a heavy-duty metal roofing and wall cladding profile widely used in commercial, industrial, and agricultural construction. The profile features deep sinusoidal corrugations that provide increased structural rigidity and improved load-bearing capability.
The designation 27/111 refers to the geometric characteristics of the profile:
• 27 mm rib height
• 111 mm rib pitch (distance between wave peaks)
This deeper corrugation profile increases panel strength and allows the roofing sheet to span longer distances between structural supports compared with lighter corrugated sheets.
27/111 corrugated panels are commonly used in:
• warehouses
• factories
• agricultural buildings
• industrial roofing systems
• wall cladding systems
• storage facilities
The panels are manufactured using roll forming machines that continuously shape flat steel coil into a sinusoidal corrugated pattern. Roll forming allows panels to be produced in custom lengths to match roof dimensions.
This guide provides a detailed technical overview of 27/111 corrugated panel dimensions, rib spacing, steel gauges, coil width requirements, and engineering span tables used by manufacturers, engineers, contractors, and roll forming machine buyers.
What is a 27/111 Corrugated Panel
A 27/111 corrugated panel is a metal roofing sheet formed with deep sinusoidal waves that increase the stiffness of the panel.
The deeper corrugations improve the structural performance of the sheet by distributing loads across the entire panel surface.
Key characteristics include:
• deep sinusoidal corrugations
• increased structural strength
• efficient water drainage
• longer span capability
• durable roofing performance
Corrugated sheets using the 27/111 profile are commonly used where stronger roofing sheets are required.

27/111 Corrugated Panel Span Tables
Span tables determine the maximum distance the panel can span between structural supports.
Span capability depends on several factors including:
• steel thickness
• corrugation depth
• panel width
• wind loads
• snow loads
Typical span ranges include:
