 What width do the sheets actually cover when lapped on the roof?
The 34/1000 profile sheets actually cover 1 metre, our stock corrugated covers 760mm.
How much should each sheet be lapped?
Just 1 corrugation or profile. However you may want to lap more corrugations or profiles on the last sheet of the run so the last sheet dose not protrude over the end of the roof.
When using TEK self drilling screws, do you fit them on the top or the lower part of the sheet profile?
The lower part. They have a neoprene washer below the screw head to prevent leaks and as long as the screws are fitted square, there should be no leaks. If the screws were fitted to the top of the profile the profile and sheet would distort as the screw is tightened.
What are the minimum and maximum lengths sheets can be made to?
Minimum length is around 750mm, maximum is around 12 metres, however this would be on a collection only basis.
Is there any minimum order size?
Not usually, but there will be a delivery charge.
If second quality sheets are ordered, can they be sorted so they are the same colour?
No, they are sold as they rise out of the pack.
What do the sheets weigh?
They tend to vary according to sheet thickness and width but in general a 3m sheet will weigh around 18kg |
