Profile cross-section — schematic, not to scale
Overview
T20 is the profile most roofs actually need: a shallow trapezoidal section, fixed through the flat with painted-head screws, laid over battens or a deck. It is quick to set out, quick to lay and quick to replace a damaged sheet in twenty years' time.
We roll it to the length of the run rather than to a stock length, so a typical pitched roof is a single sheet from ridge to eaves with no transverse lap to seal, no water held on a lap and no double thickness at the fixing line.
Exposed fixings are a deliberate choice here, not a compromise. On a straightforward pitched roof they are faster, cheaper and — with the correct fastener, torque and washer — entirely durable.
Applications
- Residential pitched roofs
- Agricultural buildings
- Light commercial and storage
- Garages and outbuildings
- Re-roofing over existing cover
01
Cut to length
Sheets are produced to the run, so most roofs need no transverse lap at all.
02
Fixed through the flat
Fastening through the pan rather than the rib keeps the washer in compression and the fixing tight.
03
Fast to lay
A simple side lap and generous cover width make T20 one of the quickest profiles to close a roof with.

On-screen colours are approximations. Coated steel changes appearance with gloss level, surface texture, viewing angle and daylight. Always confirm a colour against a physical VANKKA sample before ordering.
