02 Dec Siemens Warehouse Case Study
One of many new construction projects in Western Australia resulting from the past mining boom!
In 2013, the multi-disciplined provider, Siemens won a contract to supply the Roy Hill Iron Ore mine, and in 2015, made the decision to set up a service centre in Perth, Western Australia.
A typical commercial warehouse includes steelwork for the columns, roof trusses, and bracing. Being a critical component of the buildings structural framework, the steel items needed to be protected from the elements.
For example, the $6m Siemens building contained around 120T of Structural Steel, which was painted in a single coat, Inorganic Zinc system, over a class 2.5 blast.
Coating Tips for Commercial Structural Steelwork
Over the past 50 years, Ferro-Clean has processed many similar projects to Siemens. Here are some useful tips for protective coatings;
· The most commonly used primer suitable for indoor steelwork is Grey/Red Oxide Zinc Phosphate (ROZP or GOZP), typically to around 50-75µm thick, over a Class 1 or Class 2 blast. See Case Study 7 – Aldi Supermarket for an example of this paint system.
· Greater protection comes with Inorganic Zinc Silicate (IZS) – as shown in the photo below, which can provide an equivalent but more cost effective corrosion control than hot dip galvanising. This is usually applied to between 75-100µm, over a Class 2.5 blast.
· Two-coat systems allow choices of gloss and colours, by using an epoxy primer, then a polyurethane topcoat, both applied at around 75-100µm each, over a Class 2.5 blast. See Case Study 4 – Masters Joondalup Store for an example of a two-coat paint system.
· Three-coat systems are designed for highly corrosive environments, such as chemical factories or fertilizer plants. They would usually be several hundred microns thick, and different types of paint are used, depending on the circumstances, usually over a Class 2.5 or Class 3 blast. See Case Study 6 – Kalgoorlie Gold Mine Upgrade for an example of a three-coat paint system.
