34/1000 Box Profile Panel Dimensions, Rib Spacing, Gauge Range, and Span Tables
34/1000 Box Profile Panel Dimensions, Rib Spacing and Span Tables
34/1000 Box Profile panels are a heavy-duty trapezoidal metal roofing and wall cladding profile widely used in industrial, commercial, and agricultural construction. The profile features deep trapezoidal ribs that provide excellent structural rigidity and load-bearing capacity while maintaining efficient water drainage.
The designation 34/1000 refers to the panel geometry:
• 34 mm rib height
• 1000 mm effective coverage width
This design provides increased structural strength compared with shallower box profiles, allowing the panel to span greater distances between roof supports.
34/1000 box profile sheets are commonly used in:
• warehouses
• factories
• industrial buildings
• agricultural buildings
• commercial roofing systems
• 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 process, panels can be produced in custom lengths to match building dimensions.
This guide provides a detailed technical overview of 34/1000 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 34/1000 Box Profile Panel
A 34/1000 box profile panel is a trapezoidal metal roofing sheet designed with multiple structural ribs that increase the stiffness of the sheet.
Unlike corrugated panels that use curved waves, box profile panels use angular trapezoidal ribs which provide stronger structural reinforcement.
Key characteristics include:
• trapezoidal rib geometry
• increased structural stiffness
• large coverage width
• strong water drainage performance
• efficient manufacturing process
Box profile panels such as the 34/1000 profile are commonly used in large commercial and industrial buildings.
