Marshall Industries’ High Profile Trays are the perfect product when water carrying and thermal expansion are a main consideration. Manufactured on our premises, this profile can be used on roofs with a pitch of three degrees or more and has the best water carrying capacity on the New Zealand market. High Profile Trays also incorporate concealed fixings, accommodating thermal expansion on long lengths meaning very long lengths can be installed without the need for over-sized holes in the roof for fixings.
