32/8 Corrugated Panel Dimensions, Rib Spacing, Gauge Range, and Span Tables
32/8 Corrugated Panel Dimensions, Rib Spacing and Span Tables
32/8 Corrugated panels are a classic metal roofing and cladding profile widely used in residential, agricultural, and light industrial construction. The profile features a repeating sinusoidal wave pattern that provides strength and stiffness while maintaining a lightweight sheet structure.
The designation 32/8 refers to the panel’s geometric characteristics:
• 32 mm rib pitch (distance between wave peaks)
• 8 mm rib height
This shallow corrugation profile produces a lightweight roofing sheet that is economical to manufacture and easy to install. Because of its smaller rib height, the 32/8 corrugated sheet is commonly used for lightweight roofing and cladding applications.
Typical applications include:
• residential roofing
• agricultural buildings
• garages and sheds
• wall cladding systems
• storage buildings
• fencing and siding
32/8 corrugated sheets are manufactured using roll forming machines that continuously shape flat steel coil into a sinusoidal wave pattern. The roll forming process allows the sheet to be produced in long custom lengths that match roof dimensions.
This guide provides a detailed technical overview of 32/8 corrugated panel dimensions, rib spacing, steel gauges, coil width requirements, and engineering span tables used by manufacturers, contractors, engineers, and roll forming machine buyers.
What is a 32/8 Corrugated Panel
A 32/8 corrugated panel is a metal sheet profile formed with shallow sinusoidal corrugations.
The corrugated wave pattern increases the stiffness of the sheet and distributes loads across the panel surface, allowing thin steel sheets to achieve structural strength.
Key characteristics include:
• shallow sinusoidal wave pattern
• lightweight panel structure
• efficient water drainage
• simple manufacturing process
• economical roofing solution
Corrugated panels using the 32/8 profile are widely used because they provide a balance between strength and lightweight construction.
Standard 32/8 Corrugated Panel Dimensions
32/8 corrugated panels are manufactured in several widths depending on the number of corrugations across the sheet.
Typical dimensions include:
Specification
Typical Measurement
Coverage Width
760 – 1000 mm
Overall Width
820 – 1080 mm
Rib Height
8 mm
Rib Pitch
32 mm
Number of Corrugations
20 – 30
Panel Length
Custom roll formed
Effective coverage width depends on panel overlap during installation.
Corrugation Rib Layout
The corrugation layout consists of closely spaced sinusoidal waves repeated across the sheet width.
Typical characteristics include:
• smooth curved corrugations
• uniform rib spacing
• shallow wave pattern
Typical corrugation dimensions include:
Feature
Measurement
Corrugation height
8 mm
Corrugation pitch
32 mm
Corrugation spacing
32 mm center to center
The shallow corrugations provide stiffness while maintaining lightweight sheet construction.
32/8 Corrugated Panel Cross Section Dimensions
The cross section of the 32/8 corrugated panel is formed gradually through a series of roll forming stations.
Typical cross section characteristics include:
Corrugation height
8 mm
Corrugation pitch
32 mm
Panel overlap
1 corrugation
Panel coverage width
Typically 760 – 1000 mm
The side overlap prevents water penetration between adjacent panels.
Steel Gauge Range for 32/8 Corrugated Panels
32/8 corrugated sheets are typically manufactured using light steel gauges.
Common gauges include:
Gauge
Thickness
Typical Application
30 gauge
0.0120 in
Decorative cladding
29 gauge
0.0142 in
Residential roofing
28 gauge
0.0157 in
Agricultural buildings
26 gauge
0.0179 in
Light industrial roofing
Thicker gauges are sometimes used where greater structural strength is required.
32/8 Corrugated Panel Span Tables
Span tables determine the maximum distance the panel can span between roof supports.
Span capability depends on:
• steel thickness
• corrugation depth
• panel width
• wind loads
• snow loads
Typical span ranges include:
Gauge
Roof Span
30 gauge
1 – 2 ft
29 gauge
2 – 2.5 ft
26 gauge
3 – 4 ft
Engineering calculations should always be performed for specific building designs.
Coil Width Requirements for 32/8 Corrugated Panels
Steel coil must be slit to the correct width before entering the roll forming machine.
Typical coil widths include:
Panel Coverage
Coil Width
760 mm panel
820 – 840 mm coil
914 mm panel
980 – 1000 mm coil
1000 mm panel
1060 – 1080 mm coil
Additional width is required to account for the corrugation forming process.
Correct coil width ensures accurate panel coverage after roll forming.
Materials Used for 32/8 Corrugated Panels
32/8 corrugated panels can be manufactured using several metal materials depending on the project requirements.
Common materials include:
Galvanized steel

Common Manufacturing Problems
Manufacturing problems may occur if roll forming machines are not properly adjusted.
Common problems include:
Uneven corrugation spacing
Panel waviness
Incorrect corrugation height
Edge distortion
These issues can usually be corrected by adjusting roll tooling alignment and forming pressure.
