ZINCALUME® window flashing is a precision-engineered Z flashing designed to protect window openings from moisture, wind and water ingress. Made from genuine BlueScope ZINCALUME® steel, it combines strength, clean lines and corrosion resistance for long-term performance in Australian conditions.
This flashing is used at the head, sill and jamb of windows to create a watertight barrier between cladding and framing. It helps direct water away from the opening, protecting internal walls and insulation from leaks and rot.
✔ Suitable for residential and commercial builds
✔ Ideal for use with COLORBOND® and ZINCALUME® wall cladding
✔ Available in standard Z profile or custom sizes to your specs
ZINCALUME® steel offers proven corrosion resistance and a long service life. Its metallic coating provides superior protection in coastal and high-moisture areas compared to standard galvanised options. Each flashing is made from 0.55 BMT BlueScope steel and carries the BlueScope warranty for peace of mind.
