Fiberr corrugated fiberglass-reinforced plastic sheets combine the
corrosion resistance and low weight of FRP with formed ribs that increase
panel stiffness. Corrugated sheets are used for roofing, siding,
equipment enclosures, cooling-tower casing, industrial cladding,
daylighting, and replacement panels in corrosive or high-moisture
environments.
The available profiles range from closely spaced, shallow corrugations
for conventional roofing and siding to wide, deep structural ribs for
large-area industrial cladding. Profiles may also be selected to match
existing metal, cement, or FRP panels during retrofit and replacement
projects.
Corrugated FRP sheet provides increased profile stiffness while
maintaining low weight and corrosion resistance.
Corrugated profiles are available for roofing, siding, cladding,
cooling towers, enclosures, and replacement-panel applications.
Profile dimensions: Each profile is identified by its
nominal pitch and depth. Pitch is the horizontal distance from one
repeating crest to the next. Depth is the vertical distance from the
crest to the trough. Greater profile depth generally provides increased
stiffness, while pitch affects panel appearance, overlap, coverage, and
compatibility with adjacent panels.
Profile Selection
Select the profile based on the required application, existing panel
compatibility, clear span, support spacing, panel thickness, wind
loading, drainage, overlap, and fastening arrangement.
Custom Construction
Profiles can be produced with configurable thickness, reinforcement,
resin, color, UV protection, fire-retardant formulation, surface finish,
and opacity, subject to manufacturing requirements.
Profiles Made to Specification
In addition to the profiles listed below, Fiberr can produce corrugated
profiles to customer specification. Provide a dimensioned drawing,
physical sample, profile tracing, or detailed pitch, depth, crown,
trough, overlap, and coverage dimensions for review.

Existing-panel matching: When replacing or extending an
existing roof or wall system, provide a dimensioned drawing, profile
tracing, physical sample, or clear measurements of the pitch, depth,
crown width, trough width, rib shape, overlap, and panel coverage.
Nominal pitch and depth alone may not establish full profile
compatibility.
Custom corrugation profiles: Fiberr can produce
corrugated profiles to specification. Custom profile development is
subject to technical review, tooling requirements, minimum production
quantities, material construction, and confirmation of the required
dimensions and tolerances.
General guidance only: The application descriptions are
intended as initial profile-selection guidance. Final suitability depends
on panel thickness, reinforcement configuration, resin system, support
spacing, load direction, wind pressure and suction, roof slope, drainage,
fastener type, overlap, sealing, thermal movement, fire requirements, and
applicable engineering or building-code requirements. Corrugated panels
should not be treated as walkable unless the specific construction has
been designed, tested, and approved for foot traffic.
