Deep Corrugated Panel Dimensions, Rib Spacing, Gauge Range, and Span Tables
Deep Corrugated Panel Dimensions, Rib Spacing and Span Tables
Deep Corrugated panels are a heavy-duty metal roofing and cladding profile designed with larger and deeper corrugations than standard corrugated sheets. The increased rib depth provides greater structural strength, improved load capacity, and enhanced water drainage.
This type of profile is commonly used in industrial buildings, agricultural structures, and large commercial facilities where stronger roofing sheets are required.
Deep corrugated metal panels are widely used because they provide a good balance between strength, manufacturing simplicity, and cost efficiency.
Typical applications include:
• industrial buildings
• warehouses
• agricultural structures
• storage facilities
• factories
• large roof span structures
Deep Corrugated panels are manufactured using roll forming machines that continuously shape steel coil into repeating sinusoidal corrugations. Because roll forming is a continuous process, panels can be produced in custom lengths to suit the building design.
This guide provides a detailed technical overview of Deep Corrugated panel dimensions, rib spacing, steel gauges, coil width requirements, and span tables used by engineers, contractors, architects, and roll forming machine buyers.
What is a Deep Corrugated Panel
A Deep Corrugated panel is a metal roofing and cladding sheet with larger and deeper corrugations than standard corrugated profiles.
The deeper wave pattern increases the stiffness of the sheet, allowing the panel to span longer distances between supports.
Key characteristics include:
• deep sinusoidal corrugations
• improved structural strength
• enhanced water drainage
• increased span capability
• durable roofing performance
Because of the deeper corrugations, these panels are often used on buildings that require stronger roofing materials.
Standard Deep Corrugated Panel Dimensions
Deep Corrugated panels are available in several sizes depending on the manufacturer and market.
Typical dimensions include:
Specification
Typical Measurement
Coverage Width
800 – 1000 mm
Overall Width
860 – 1080 mm
Rib Height
25 – 35 mm
Rib Pitch
100 – 150 mm
Number of Corrugations
6 – 10
Panel Length
Custom roll formed
The deeper ribs allow the panel to maintain strength even when manufactured from thinner steel.
Corrugation Rib Layout
The corrugation layout consists of repeating deep sinusoidal waves that improve the panel’s rigidity.
Typical characteristics include:
• deep wave corrugations
• consistent rib spacing
• continuous rib pattern
Typical dimensions include:
Feature
Measurement
Corrugation height
25 – 35 mm
Corrugation pitch
100 – 150 mm
Corrugation spacing
100 – 150 mm center to center
This deep rib structure significantly increases panel strength.
Deep Corrugated Panel Cross Section Dimensions
The cross section of deep corrugated panels is created using multiple roll forming stations that gradually shape the sheet into the corrugated profile.
Typical cross section features include:
Corrugation height
25 – 35 mm
Corrugation pitch
100 – 150 mm
Panel overlap
1 corrugation
Panel coverage width
Typically 800 – 1000 mm
Panel overlap ensures water cannot penetrate the joints between adjacent sheets.
Steel Gauge Range for Deep Corrugated Panels
Deep Corrugated panels are often manufactured using heavier steel gauges to handle increased structural loads.
Common gauges include:
Gauge
Thickness
Typical Application
26 gauge
0.0179 in
Agricultural buildings
24 gauge
0.0239 in
Commercial roofing
22 gauge
0.0299 in
Industrial buildings
20 gauge
0.0359 in
Heavy structural roofing
Thicker gauges are often selected for buildings exposed to high wind or snow loads.
Deep Corrugated Panel Span Tables
Span tables determine the maximum distance the panel can span between structural supports.
Span capability depends on:
• steel thickness
• corrugation depth
• panel width
• wind loads
• snow loads
Typical span ranges include:
Gauge
Roof Span
26 gauge
3 – 4 ft
24 gauge
4 – 6 ft
22 gauge
6 – 8 ft
20 gauge
8 – 10 ft
Engineering calculations must always be performed for specific building designs.
Coil Width Requirements for Deep 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
800 mm panel
860 – 880 mm coil
914 mm panel
980 – 1000 mm coil
1000 mm panel
1060 – 1080 mm coil
Extra material is required to account for the deep corrugation forming process.
Correct coil width ensures accurate panel coverage.
Materials Used for Deep Corrugated Panels
Deep Corrugated panels can be manufactured using several metal materials depending on project requirements.
Common materials include:
Galvanized steel
Galvalume steel
Aluminum
Painted steel
Galvalume steel is widely used for roofing due to its corrosion resistance and durability.
Industries Using Deep Corrugated Panels
Deep Corrugated panels are widely used in industries where strong and durable roofing materials are required.
Common applications include:
Industrial buildings
Warehouses
Agricultural facilities
Factories
Large storage buildings
Commercial roofing systems
These panels are particularly useful for buildings with larger roof spans.
Roll Forming Machines Used to Produce Deep Corrugated Panels
Deep Corrugated panels are produced using roll forming machines designed for deeper corrugated profiles.

Deep corrugated roll forming machines are widely used in roofing panel manufacturing.
Installation Considerations
Correct installation is essential to ensure the performance of deep corrugated roofing systems.
Important installation factors include:
Correct panel overlap
Proper fastener spacing
Roof slope requirements
Sealing of panel joints
Panels are typically overlapped by one corrugation to prevent water penetration.
Engineering Load Considerations
When designing deep corrugated roofing systems, engineers must consider several structural factors including:
Wind uplift loads

Thermal expansion
Deep corrugated panels are typically installed over purlins or structural supports.
Common Manufacturing Problems
Manufacturing issues may occur if roll forming machines are not properly adjusted.
Common problems include:
Uneven corrugation spacing
Panel waviness
Incorrect corrugation depth
Edge distortion
These problems can usually be corrected by adjusting roll tooling alignment and forming pressure.
