We specialise in supplying robust Armour Sheet and Plates, materials chosen for the toughest jobs where failure is not an option.

We are your local partner, committed to providing the durable foundations and protective solutions that industry across New Zealand depends on every day.
The composition of these plates is precisely engineered to absorb and disperse immense impact. This results in exceptional mechanical properties, including very high tensile strength and outstanding hardness, which resists abrasion and penetration. While they are incredibly tough, they also maintain crucial structural integrity, meaning they can withstand repeated stress without cracking. Essentially, these plates offer a remarkable balance; they are hard enough to resist wear and tear but tough enough to handle heavy impacts, making them a uniquely resilient material.
