Proscaf Steel:
The Proscaf Steel Scaffolding System is a very popular and commonly used scaffolding system in NZ and AU. Proscaf Steel is a ringlock system and is the most efficient system scaffold on the market. Proscaf Steel has industry leading diagonal braces and therefore it can achieve more than most systems on the market. Proscaf steel can be used for a huge variety of projects from day-to-day façade scaffolding projects to heavy duty propping and cantilever scaffolding.
So, what’s the difference between Proscaf Steel and Aluminium?
Proscaf Steel and Proscaf Aluminium almost look identical and work together seamlessly. However, there are a few differences and applications that Proscaf Aluminium excels in. We cover this off below.
Proscaf Aluminium:
Proscaf Aluminium is a highly versatile system and integrates seamlessly with Proscaf Steel. The main difference is the weight of the system. Proscaf Aluminium is 46% lighter than Proscaf Steel which provides many benefits.
Before we dig in, we want to address a common misconception about Proscaf Aluminium. Aluminium scaffolding is not like aluminium scaffold towers. Unlike mobile towers which are modular and are used to access one area, Proscaf Aluminium is extremely versatile and can handle large loads.
When compared to steel, aluminium has a coefficient of elasticity equal to one third. In essence, its elastic deformation under a load is three times greater than steel. This means that Proscaf Aluminium has more flex than steel systems, giving the impression that it is weaker. This is not the case because while steel has a higher rigidity, the strength to weight ratio of steel vs aluminium is 2.8:1. Proscaf Aluminium has a thicker internal wall dimension than Proscaf steel to achieve its high weight rating. The outside dimensions of the system are the same as Proscaf Steel which means it is compatible with Proscaf Steel
Ideal Applications of Proscaf Aluminium:
SCAFFOLDING FOR RESIDENTIAL HOUSING
The typical residential house scaffold only stands onsite for 4-6 weeks. The largest cost of the project to the scaffolder is labour in the erection and dismantle. Proscaf aluminium is 46% lighter than most steel systems: a scaffolder carrying 20kg of equipment means 2 x 3.07m steel ledgers or 5 x 3.07 aluminium ledgers. A recent case study proved that the installation and dismantle time on a single-story new build is reduced by 28% using Proscaf Aluminium. The time saved in transport and movement of Proscaf Aluminium has been proven to be a more economical system for scaffolding short-term projects.
SUSPENDED SCAFFOLDING
Proscaf Aluminium is designed to be able to be used for suspended/ hanging scaffold projects. Proscaf Aluminium is a 6061-T6, marine grade aluminium. The strength to weight ratio of this grade of aluminium is twice that of steel allowing scaffold contractors to build suspended platforms with a lower tare weight. The extra-strong spigots are double bolted, suiting suspended scaffolding projects. The impressive strength to weight ratio of Proscaf Aluminium makes it suited for the maintenance of structures like wharfs and bridges that have weight restrictions.
CANTILEVER SCAFFOLDING
Proscaf Aluminium is unique for its ability to cantilever using the load-bearing diagonal brace. With industry high compression and tension loads, complex projects can be achieved. Applications are for industrial and energy projects where irregular structures present challenges for standard modular equipment. The anti-corrosion and non-sparking elements of Proscaf element are also a benefit in these applications.
