BISALLOY® Structural Steel is a high-performance quenched and tempered steel plate that offers superior mechanical properties compared to traditional carbon steels. This steel is engineered to deliver consistent and reliable performance, meeting stringent Australian and international standards. It is available in a variety of grades and thicknesses, allowing designers and engineers to tailor material selection to specific project requirements while optimising weight and cost.
BISALLOY® Wear Steel is purpose-designed for extreme wear resistance applications, combining high hardness with toughness to withstand abrasion, impact, and harsh operating conditions. It is produced through precise alloying and heat treatment processes that ensure a durable, hard surface without sacrificing structural integrity. This product line offers grades with hardness levels ranging from 450 HB to 600 HB, allowing selection based on specific wear demands. Despite its hardness, BISALLOY® Wear Steel remains remarkably formable, weldable, and machinable, enabling complex fabrication and maintenance tasks.
BISALLOY® Armour Steel is a specialized quenched and tempered steel plate developed to meet the rigorous ballistic and impact resistance demands of military and defense applications. Its ultra-high hardness and toughness provide protection against a range of ballistic threats while maintaining a relatively lightweight profile. Manufactured to meet or exceed military specifications such as MIL-DTL-46100 and MIL-DTL-12560, BISALLOY® Armour Steel is widely trusted in the design and manufacture of armoured personnel carriers, light armoured vehicles, naval vessels, and protective barriers.
BISALLOY® Protection Steel offers a robust solution for applications where ballistic protection is required, but full military-grade armour may not be necessary. It provides reliable protection against low to medium velocity threats and blunt force, making it suitable for a wide variety of civil, commercial, and security applications. Tested by independent laboratories and validated by multiple end users, BISALLOY® Protection Steel is employed in armoured cars, patrol vehicles, valuables transportation, and secure facility construction.
