SECURITY STEEL WINDOWS & DOORS NZ
The history of security windows is intertwined with the evolution of building security and safety measures. The need for windows that provide enhanced protection against forced entry, vandalism, detention cell integrity, and other security threats has driven innovations in materials and design. Here's an overview of the history of security windows.

Security Windows and Doors
21st Century
-
Advanced Materials: The 21st century has seen the use of advanced materials in security windows, including polycarbonate, which is known for its strength and impact resistance.
-
Ballistic Resistance: Security windows designed to resist ballistic threats have become more prevalent, particularly in high-risk environments such as government buildings and financial institutions.
-
Electronic Security Integration: Modern security windows may also incorporate electronic security features, such as sensors and alarms, to enhance overall building security.
-
Energy Efficiency: In addition to security considerations, there is an increasing emphasis on energy efficiency in building design. Some security windows are designed to provide both security and energy-saving benefits.
Today, security windows come in various forms to meet specific needs, including laminated glass, bullet-resistant glass, impact-resistant glass, and more. They are used in a wide range of applications, from residential properties to commercial and government buildings.
The evolution of security windows reflects the ongoing efforts to balance architectural aesthetics with the need for enhanced protection and safety in diverse environments. As security threats continue to evolve, so too will the technology and design of security windows to meet these challenges.
Steel is very strong and a very cost effective material, therefore it is extensively used in the security area. Steelguard's security products are in almost all prisons in New Zealand and numerous police stations, court houses, mental health facilities, and other buildings which require high security eg. retail and datacenters.
Tested and Approved
Our security products are tested internally and in WSP labs. WSP helps test, engineer, and certify buildings and infrastructure projects, so you know that our security products are proven to perform in demanding real-world environments.
We have done security work in many prisons across the country, including:
-
Auckland Prison
-
Auckland Central Remand Prison
-

Strong Welded Connections
Security Doors

Steelguard steel security doors are engineered for strength, reliability, and long-term performance in high-security environments. Built from steel, they control access, improve safety, and resist forced entry and wear. Available in multiple configurations, they suit commercial, public, healthcare, and correctional facilities.
Interview Screens

Steelguard steel interview screens provide a secure barrier for controlled interactions in correctional, healthcare, and secure public settings. They enable clear communication while maintaining separation, improving safety, and reducing risk during interviews or consultations.
Security Windows

Steelguard steel security windows provide high levels of protection. Made from durable steel framing, they help resist forced entry, vandalism, and impact damage. Suitable for commercial, government, healthcare, and correctional environments, they are built for demanding conditions.
Cells

Steelguard manufactures secure steel cell systems for custodial and correctional environments. These provide safe, durable, and controlled spaces for staff and occupants, including cell doors, framing, viewing panels, and secure hardware.
