Normally when choosing your decking whether wood or WPC you need to buy fixed sized planks, and they usually come in lengths of 2.5, 3.6 and 5.4m (other lengths are available depending on your region). When it’s ready to be laid the installer will measure the length that’s required and cut the plank accordingly. No matter how careful they are there is always wastage (off-cuts). We always accept wastage from these kinds of jobs for recycling.
VANZEEL WPC will calculate the amount of material required from the dimensions you provide from your plan
