The ZINCALUME® external quad gutter cast angle is designed to form a 90-degree external corner on 115mm quad gutter systems. Manufactured as a single-piece cast fitting, it provides a strong, neat junction that supports consistent water flow around external corners.
This product is compatible with Lysaght 115mm Quad Gutter profiles and is commonly used in residential and light commercial installations where durability and long service life are required. The cast design eliminates the need for complex mitre folding, making it a reliable option for achieving a professional finish.
Installation is completed by sliding the cast angle into position from underneath the gutter. The connection is then sealed and fixed using silicone sealant and rivets to create a secure, watertight joint.
Manufactured from ZINCALUME® steel made by BlueScope, this external quad gutter cast angle offers excellent corrosion resistance and is well suited to Australian conditions. Proudly made in Australia from 100% Australian steel, it meets the expectations of both trade professionals and customers seeking long-term performance.
