The PUF roof panel profile in our range is "six-ridge with 30 mm crest": the top sheet is formed into six ribs across the panel's 1.00 m chargeable width, each standing 30 mm proud of the flat, on every roof panel from 30 to 100 mm, as printed on 25 September 2026. The home page puts its purpose in one line: a six-ridge profile for added rigidity across the span. On 23 Sep 2026 the 50 mm roof panel carrying it, with 0.5 / 0.3 mm sheets, was ₹ 1,269 per sqm at the 3,000 sqm slab, ex-factory Kathua, GST and freight extra (factory prices on 23 Sep 2026). Profile row and today's rate: 50 mm roof panel specification.
PUF roof panel profile: what a rib does to a sheet
A flat sheet of 0.5 mm steel bends under its own weight between two supports. Fold a rib into it and the sheet becomes a series of small beams: the rib's height is the depth of the beam, and stiffness rises steeply with depth. Six ribs across a metre, each 30 mm high, turn a limp sheet into a deck that spans between purlins and takes a foot without oil-canning.
On a sandwich panel the foam and the flat bottom sheet already make the panel a beam in its own right. The ribs add stiffness to the top sheet itself, between the foam and the weather: the local stiffness that resists a dropped tool, a boot, hail, and the flutter of wind over a large roof.
Drainage and laps
A rib is also a channel. Water landing on the roof runs down the valleys between ridges to the eave; the crests stand clear of the flow. At the side joint, one panel's edge rib laps over the next panel's, so the joint sits on a crest, above the water line. That is why a roof panel is billed on cover width, 1.00 m, rather than the sheet's full width: the lapping rib is not roof.
Trapezoidal PUF roof sheet: the shape
A trapezoidal profile is a rib with sloping sides and a flat crest, as against a rounded corrugation. Ours is stated by count and height, six ridges and a 30 mm crest; the width of the crest and the valley are not printed on the page. What the specification fixes is the height, which is the figure that governs stiffness and the depth of water a valley can carry.

The profile is the same at every thickness. What thickness adds is the depth of the whole panel, foam included; what the profile adds is the stiffness of the top skin. A 100 mm panel is a far deeper beam than a 30 mm one, but both carry the same six ribs on top.
Why the wall panel has none
A wall does not shed water across its face or carry a person, and a flat face is what a cold room or a clean corridor wants. The wall panel is flat, on a 1150 mm module. The profile is a roof panel's feature, for a roof panel's job.
What the profile does not decide
Span between purlins, fixing pattern and minimum slope are the designer's, from the loads and the roof geometry; our page states the profile and leaves those to the design.
Frequently asked questions
What is the profile of a PUF roof panel?
Ours: six ridges across the 1.00 m chargeable width, each with a 30 mm crest, formed in the top sheet, on every roof panel thickness as of 25 Sep 2026.
Why does a PUF roof panel have ridges?
For rigidity across the span, for drainage down the valleys, and to put the side lap on a crest above the water line.
Is the PUF roof panel profile trapezoidal or corrugated?
It is a ridge profile with a stated crest height of 30 mm; the page gives the count and height, not the crest and valley widths.
Do wall panels have the same profile?
No. Wall panels are flat, on a 1150 mm module.
