Webinar: NZS 3404.3:2026 – Durability of Steel Structures Practical Guidance for Designers

NZS 3404.3 – Durability of Steel Structures: Practical Guidance for Designers Steel Construction New Zealand (SCNZ) is delighted to offer this technical session for engineers, architects, and all professionals involved in specifying coatings and durability for steel structures. Durability is fundamental to sustainable construction and to achieving resilient, low-maintenance buildings and bridges. With the upcoming release of NZS 3404.3:2026, there is clearer guidance on material performance, corrosion protection, maintenance expectations, and how to design, specify, and protect steel structures for their intended service life. Applying these requirements correctly will help the construction industry deliver longer-lasting structures while reducing whole-of-life costs and environmental impacts. This webinar will provide a practical overview of NZS 3404.3:2026 and will: Introduce the key principles and updates within NZS 3404.3, that replaces SNZ TS 3404. Clarify roles and responsibilities in specifying durability and coating systems Explain how to correctly specify durability requirements for steel structures Explore corrosion environments and appropriate protection systems Demonstrate how durability decisions influence whole-of-life performance
