Why Is Stainless Steel Roof Safety Mesh Superior to Galvanized?

Aug. 15, 2023

What is Roof Safety Mesh?


Stainless steel roof safety mesh is designed to prevent internal falls through a roof. It provides fall protection for roof installers and offers long-term protection against falling for maintenance and repair workers. Roof safety mesh is installed between the roof skin and the purlins. Access to the inspect the Roof Safety Mesh therefore is quite difficult as it involves working at height and having to move around those objects that are stored in the building. This makes inspecting Roof Safety Mesh almost impossible which is why you need a product that lasts longer than the roof itself.


Why is Stainless Steel Roof Safety Mesh Superior to Galvanized?

Roof Safety Mesh is an important product to prevent workplace injuries in Australia. In the Compliance Code: Prevention of Falls in General Construction, Roof Safety Mesh is a part of 'level 2' controls, as a Passive Fall Prevention Device. Commercial roofs are required to be built to Industry Standards and these standards take into consideration the typical function of the building.


In all cases, Roof Safety Mesh is required to be installed as access will be required for gutters, air conditioning, lighting, aerials etc. The safe work Australia code of practice for Managing the Risks of Falls at Workplace instructs that Roof Safety mesh should comply with AS/NZS 4389:2015 and be installed by competent people in accordance with manufacturer's instructions.


Stainless steel wire mesh can be used in harsh environments, such as beaches. The image to the right shows galvanised roof safety mesh at Brighton Beach, Victoria. The mesh is exposed to harsh coastal, so the galvanised has corroded and rusted overtime, and will need to be replaced. Stainless Steel is the best practice for the Roof Safety Mesh installation, especially in harsh conditions as it lasts longer than the building itself, and requires minimal maintenance in return for long lasting, superior quality performance.


Roof safety mesh should meet the requirements of AS/NZS 4389:2015 – Safety Mesh. This standard provides a specification for the mesh and for the load testing of the mesh, which involves the dropping of a 166kgm, 1500mm long, 350mm diameter bag onto installed mesh from a height of 1.4m, as seen to the right.


ㆍAS/NZS 4389:2015 'Safety Mesh' exceeds technical requirements & complies to load testing

ㆍAS 2331.3.1:2001 (R2017) 'Neutral Salt Spray Test' PVC Coated tested to 96 hours


Roof Safety Mesh also needs to be compliant with safety standards. This is due to 13% of worker fatalities in Australia are caused by falling from heights. Heights above 2 metres are considered "high risk" so the material installed must be durable, reliable, and long lasting.


Why when specifying the type of material for Roof Safety Mesh must we consider the environment and applications?


The main factor when deciding what material to specify for Roof Safety Mesh, is the environment that the mesh will be exposed to. There are several conditions that we need to consider when selecting the type of Roof Safety Mesh. These are:

Stainless Steel Wire Mesh


ㆍHumidity & Moisture

ㆍThermal Expansion

ㆍChemical Exposure

ㆍDissimilar Metals


The type of stainless steel roof safety mesh needs to take into consideration these conditions and still deliver the safety performance required for the life of the building.




Stainless Steel Roof Safety Mesh is commonly used for roofing critical assets and infrastructure. Stainless steel can withstand harsh environment including coastal and highly corrosive environments common applications include:




ㆍShopping Centres


ㆍOffice Buildings
