25/210 Industrial Panel Dimensions, Rib Spacing, Gauge Range, and Span Tables
25/210 Industrial Panel Dimensions, Rib Spacing and Span Tables
The 25/210 Industrial Panel is a trapezoidal metal roofing and wall cladding profile designed for light industrial buildings, commercial structures, and agricultural applications. The profile uses evenly spaced trapezoidal ribs to provide structural rigidity while maintaining efficient water drainage and economical steel usage.
The designation 25/210 refers to the geometry of the profile:
• 25 mm rib height
• 210 mm rib pitch (center-to-center spacing)
This configuration provides a cost-effective roofing panel suitable for many metal building systems where moderate strength and large coverage width are required.
25/210 industrial panels are commonly used in:
• warehouses
• agricultural buildings
• light industrial buildings
• storage facilities
• commercial roofing systems
• wall cladding systems
These panels are manufactured using roll forming machines that shape steel coil into trapezoidal ribs through multiple forming stations. Because roll forming is a continuous process, panels can be produced in long custom lengths to match building roof dimensions.
This guide provides a detailed technical overview of 25/210 industrial panel dimensions, rib spacing, steel gauges, coil width requirements, and span tables used by engineers, contractors, manufacturers, and roll forming machine buyers.
What is a 25/210 Industrial Panel
A 25/210 industrial panel is a trapezoidal metal roofing sheet with structural ribs designed to improve the stiffness and load distribution of the panel.
Compared with traditional corrugated roofing sheets, trapezoidal industrial panels offer:
• improved structural stiffness
• higher span capability
• better water drainage
• more efficient installation
Because of these advantages, trapezoidal profiles such as the 25/210 panel are widely used in modern metal building construction.
