Alukap high span wall bars are used to create an aesthetically pleasing finish in situations where the glazing of an Axiome polycarbonate sheet structure butts against a rising wall. The bar features an integrated upstand that ensures a waterproof connection to lead flashings or for flash bands to drop down over, both of which will speed up installation time. High span bars are an ideal choice for those who want to have less posts supporting their polycarbonate structure.
