The Tilcor difference

Our dedication to high quality materials, and advanced and innovative processes puts our metal roofing systems above the rest. From what goes into making Tilcor roofing right through to valuable installation support, there’s no other roofing solution quite like it. Let's take a look at some of the ingredients that make our stone-coated steel panels the best.

High quality steel

Tilcor’s steel products are made from 100% NZ black ironsand, so you’re guaranteed the highest quality. This unique and valuable product is known as the purest form of steel in the world.

Black iron sand was formed 2.5 million years ago from rock deposited on the coast by volcanic activity. Over time, the heavy dark ironsands have been carried by ocean currents and deposited on beaches, in the form of dunes. Once refined, this pure resource provides the superior base components for Tilcor’s panels.

Natural stone granules

The stone coating on all of our textured roofing products is made up of natural stone granules. These have been formed over millions of years, then ceramic coated and fired to ensure maximum durability.

Our panel coatings are made to withstand even the harshest climates, and will retain their pigment and color intensity for the lifetime of the roof. Each panel is printed with the Ross Roof Group logo, batch number, date and certification markings for ultimate traceability.


Advanced manufacturing

Tilcor remain pioneers in product innovation, research and development, which has led to our advanced manufacturing processes.

Our panels are first pressed and cut into sizes from premium coils of New Zealand steel in our Auckland factory. From there, we create uniform panels in our signature eight-layer process.

This process includes the application of Zincalume based steel on both sides, priming on both sides, acrylic base coat, natural stone granules, and finally, a pure acrylic over-glaze before being baked and hardened. The result is one of the most durable and reliable roofing systems on the market.
