35/1035 Box Profile Panel Dimensions, Rib Spacing, Gauge Range, and Span Tables
35/1035 Box Profile Panel Dimensions, Rib Spacing and Span Tables
35/1035 Box Profile panels are a widely used trapezoidal metal roofing and wall cladding profile designed for industrial, agricultural, and commercial construction. The profile features deep trapezoidal ribs that increase the structural strength of the sheet and allow it to span longer distances between roof supports.
The designation 35/1035 refers to the panel geometry:
• 35 mm rib height
• 1035 mm effective coverage width
This configuration provides strong load-bearing capacity while maintaining efficient water drainage and simple installation.
35/1035 box profile sheets are commonly used for:
• industrial buildings
• warehouses
• agricultural structures
• commercial roofing systems
• factories
• wall cladding installations
These panels are manufactured using roll forming machines that continuously shape steel coil into trapezoidal ribs. Because roll forming is a continuous manufacturing process, panels can be produced in custom lengths to match roof dimensions.
This guide provides a detailed technical overview of 35/1035 box profile 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 35/1035 Box Profile Panel
A 35/1035 box profile panel is a trapezoidal metal roofing sheet designed with multiple structural ribs that improve the stiffness of the panel.
Unlike traditional corrugated panels, box profile sheets use angular trapezoidal ribs that provide higher structural rigidity and better load distribution.
Key characteristics include:
• trapezoidal rib design
• strong structural rigidity
• wide coverage width
• efficient water drainage
• durable roofing performance
The 35/1035 profile is widely used in industrial roofing systems because it provides strong structural performance with efficient material usage.
