Yes, they are. We supply curved sheets in galvanised, polyester, and plastisol finishes. Just tell us the look you’re after, and we’ll make sure you get a finish that’s both durable and right for the job.
We manufacture curved corrugated sheets from 1.500 metres up to 4.500 metres, depending on your needs. Everything’s made to order right here at Tinman, so you get exactly what your project requires.
Minimum pitch can vary, but don’t worry—we’ll help you figure out what works for your design. Just send us your plans or measurements and we’ll advise from there.
We do this often. Whether you’re restoring a Shepherd’s Hut or replacing old curved roofing, we’ll do our best to match your existing profile and curve. Photos or a sample sheet really help—send them our way and we’ll take a look.
Absolutely. We’re not just here to supply—our team is always on hand to offer practical advice on fitting and working with curved corrugated sheets. Just give us a call.
We specialise in 13.5/3, which is made from 1220mm wide coils. Some suppliers use 14/3 from 1250mm coils. Our 13.5/3 profile is more common for galvanised and colour-coated finishes—and we find it works better for most builds.
