A quick look at the basic steps for installing a freestanding braai that will be protruding through a metal, fibreglass, steel, wood or plastic roof structure. There are other ways to do this but this is fairly straight forward. Always get professional advice and support when doing this- never attempt it alone.
”When in doubt, source it out”
1. Create a stencil for the Flue
2. Create a 2cm 'heat gap' mark
3. Mark the Flashing
4. Cut the flashing
5. Fit the Flue into the Flashing
6. Mark the roof
7. Cut the roof
8. Seal off the flashing on the roof
High humidity, water or condensation combined with extreme heat on metal surfaces are the primary causes of corrosion. Basically, where metal meets water, there is the possibility of corrosion.
Choosing stainless steel BBQ’s is a sure fire way (no pun intended) to ensure protection against corrosion.
If however you prefer a mild steel unit but are concerned about the effects of corrosion- rest assured, there are very simple ways of preventing, negating and treating corrosion. There is an upside to this- The beauty of treating your unit from time to time means that you can have a ‘new’ bbq every time you treat it!
Early treatment of Surface Corrosion:
With the changeable weather and levels of rain experienced in Europe it would be wishful thinking to believe there will not be an element of corrosion/surface rust on certain BBQ units that are exposed to the elements. You have already made a big investment and no different to your cooking units in your kitchen, these braai’s will need care and maintenance to get the best return on your investment.
Luckily there are a few precautionary and maintenance steps that can be taken to prevent or at least limit the level of corrosion that might be experienced.
If you Like it put a Roof on it! We HIGHLY RECOMMEND putting your unit under cover or some sort of roof structure! This will help to keep it dry from direct wetness like rain. It will still be exposed to dampness (in the air) but this will definitely delay the corrosion process.
Regular maintenance and early intervention is key to longevity (more detail on this below in FAQ’s). Heat and water is a lethal combination when it comes to corrosion. Heat can off course not be avoided but keeping your braai dry as much as possible is the first step towards limiting corrosion- this could be done by positioning it under a roofed structure, pergola or indoors where possible.
Our mild steel units are available in two ranges- the Classic range (discontinued) and the Home Fires range (3mm general thickness and 3.5mm in the ‘hot’ areas)
These units are shot blasted and rust treated to help protect against the elements.
Even though all possible care was taken to ensure the steel was prepared to deal with the elements, there will be a level of corrosion that will appear over time. This timeline will be expedited if the unit is not stored in a dry place, or if rust resistant products like WD40 Rust Treatment is not applied from time to time. Mild steel units’ paint work and general appearance can be refreshed by applying black heat resistant bbq/ stove paint to keep it looking fresh.
There is a misconception and generalisation that all stainless steel do not rust. There are very many grades of stainless and depending on the grade, stainless steel can rust when left untreated or ill managed, it will also discolour under high heat- turning into a deep dark blue colour when exposed to the high temperatures, like direct fire or heat from charcoal/gas.
The most common grades of Stainless steel used to produce bbq’s would be 304 and 430 grade. (more about this elsewhere in FAQ’s).
For those who prefer stainless steel we suggest the 304 Stainless Steel range, especially on coastal areas or when the unit will be exposed to very bad weather- these would be our most durable units in terms of holding up against corrosion.
Stainless steel is a tough, long lasting, durable metal. However, under certain conditions it can be subject to surface corrosion, which if left unattended could lead to rust. This is natural reaction, usually between the surface of the steel and its surroundings, but the good news is there are many things you can do to prevent this reaction or clean the rust off the steel using the correct cleaning procedure.
The same goes for Mild Steel, the upside of mild steel is that corrosion/rust marks can be sanded off with sandpaper and painted with heat resistant oven paint- giving it a new fresh look.
When surface rust first appear, WD-40 is one of the best rust treatments as it is so simple and quick. Simply spray the affected area with WD-40 and wipe it with a cloth or clean wire brush (ensure that no residue from the wire brush is left behind as this could ironically lead to further surface rust!)
