Frequently asked questions

How does Twinline differ from Microline and Offline?

The dimensions, coatings and fixing are exactly the same - only the sheet surface differs. Twinline has two pronounced longitudinal ribs, Microline a fine ribbing, Offline is completely plain. The ribs also stiffen the sheet.

Which sheet thickness should I choose?

The standard is 0.50 mm, and it is made in every coating. The thicker 0.70 mm sheet stays flatter and suits long slopes, but it is made only with the PS25 coating and a narrower colour palette - you can see it in the colour table.

Will the fixing screws be visible?

No. The sheets join with a click, and the fixing stays under the neighbouring sheet - neither screws nor joints are visible on the roof. So the roofing reads more calmly and lasts longer: there are no penetrations for water to get through.

Why is a slight waviness visible on the surface?

Classic roofing imitates a traditional metal roof, and such a roof is almost never perfectly flat. A slight waviness is a property of the profile, not a sign of a defect - it depends on temperature, lighting and viewing angle. Fitted correctly to the instructions, it stays barely noticeable.

From what pitch can it be installed?

From 8° (14%). This is one of the lowest pitches among our roofing products - the classic profile suits places already too shallow for a tile profile.

Can I get a colour sample?

Yes. We send a sample by post or show it at the factory in Kaunas - on screen a colour always looks different from coated steel.
