COLORSTEEL MAXAM® 0.4mm and 0.55mm
New Zealand Steel Limited (Bluescope)

Since the early 1980s, COLORSTEEL® has been protecting New Zealanders from the elements. Made local, made for you, and made to protect what matters most.
When it comes to roofing and cladding solutions that stand the test of time, COLORSTEEL® has always been a name you can trust. The long-lasting performance and enduring success of our products is no accident. It comes down to our relentless commitment to research and development, which is why we have introduced COLORSTEEL MAXAM® – combining the exceptional quality and consistency you know and love with groundbreaking patented ACTIVATE® technology. The result? An extension of the corrosion to perforation lifespan of COLORSTEEL®, enabling a sizeable step change in the warranties offered and thus a reduction to the whole of life embodied carbon of buildings using COLORSTEEL MAXAM® (compared to previous COLORSTEEL® products).
