Overview

BB900 has been designed with strong ribs that restrict buckling under concentrated loads reducing the chance of damage on roofs where foot traffic is common. Equally useful as wall cladding, BB900 aesthetic appeal can even further enhanced by inverting the profile to create Reverse run BB900 use in Dimond Advanced Roofing Systems.

Fastener Design

BB900 Fasteners

The durability of the fasteners should equal or exceed that of the material being fastened, and the fastener metal or coating must be compatible with the cladding material if in contact. Refer to NZS E2/AS1 table 20 for compatibility requirements. The minimum embedment of 30mm is the requirement for screws fixing into timber and minimum of three threads to pass through steel. When fastening through cavity battens, thermal break materials etc ensure the length of the screw is increased to accommodate the extra material.
