32/1000 Box Profile Panel Dimensions, Rib Spacing, Gauge Range, and Span Tables
32/1000 Box Profile Panel Dimensions, Rib Spacing and Span Tables
32/1000 Box Profile panels are one of the most widely used metal roofing and wall cladding profiles in Europe, Africa, the Middle East, and many global construction markets. The profile features trapezoidal ribs that provide excellent structural strength, efficient water drainage, and high load-bearing capacity.
The designation 32/1000 refers to the geometry of the panel:
• 32 mm rib height
• 1000 mm effective coverage width
The trapezoidal rib design increases the rigidity of the metal sheet, allowing the panel to span longer distances between supports compared with traditional corrugated sheets.
32/1000 box profile sheets are commonly used for:
• industrial buildings
• warehouses
• agricultural buildings
• factories
• commercial buildings
• wall cladding systems
These panels are manufactured using roll forming machines that continuously shape flat steel coil into trapezoidal ribs. Roll forming allows panels to be produced in custom lengths to match roof dimensions, improving installation efficiency.
This guide provides a detailed technical overview of 32/1000 box profile panel dimensions, rib spacing, steel gauges, coil width requirements, and engineering span tables used by engineers, contractors, manufacturers, and roll forming machine buyers.
What is a 32/1000 Box Profile Panel
A 32/1000 box profile panel is a trapezoidal metal roofing sheet with evenly spaced ribs designed to increase structural strength.
Unlike sinusoidal corrugated panels, box profile sheets use angular trapezoidal ribs that provide greater rigidity and improved load capacity.
Key characteristics include:
• trapezoidal rib profile
• strong structural stiffness
• large panel coverage width
• improved water drainage
• efficient manufacturing process
Box profile roofing systems are widely used because they offer higher structural performance than traditional corrugated roofing sheets.
