Questions & Answers


If I have rafters at the end of each sheet ( say 1000mm) they are 3000m long will I need any cross supports and if so at what intervals ? And what timber weight ? I’m thinking of using 16mm sheets it’s to provide a lean to roof covering over our patio with an open front


A 16mm sheet that is 3000mm long can span up to 1040mm width under its own weight, if you fixing centres are wider than this would be best to put in some purlin supports to hold up the weight of the sheet.
