Metal Flashings & Weatherproofing

Precision Engineered Metal Flashings for Long-Lasting Protection

Elliott Engineering specialises in custom metal flashings in Wellington, providing precision-engineered solutions that protect residential and commercial buildings from water damage. Using CNC press brake technology, we fabricate flashings in galvanised steel, mild steel, copper, and brass, combining superior weatherproofing with architectural detail.

Materials & Applications

Our custom metal flashings are crafted from high-quality galvanised steel, mild steel, copper, and brass to suit any project. Each material is chosen for durability, aesthetics, and long-lasting weatherproofing, ensuring your building is protected for decades.
Galvanised steel offers excellent corrosion resistance and a 30–40 year lifespan, making it a cost-effective choice for both commercial and residential applications. Mild steel can be painted to match your building’s colour scheme, providing a versatile and practical option. Copper is the premium choice for heritage or high-end buildings, offering a 70–100+ year lifespan and developing a distinctive patina that adds character over time. Brass provides a warm, decorative finish, ideal for high-end or heritage projects where aesthetic appeal is a priority.
