Metal. How to make the right choices, not knowing anything about this?

The next stage of the selection, which I had to do, and the next question, which confirmed only in practice ...

Finally, all the preparatory work in setting up the roof, are made.

Read the whole process in these articles:

It's time for the final, but important, breakthrough - fixing metal.

❗ But before something to fix, you need to have it. But to make the right choice - it is also an important task.

As always, as long as I did not specifically engaged in this, everything seemed easier (as I have a choice of AAC

) .What there to choose??? Looked where cheaper and bought... But it turns out the criteria much more.

1️⃣ size sheets.

In theory this should be no problem, can now be cut into the size what you need, even if the entire length of the ramp. But in my case is the same caveat - Mount the metal roofing, I will be me and my girl.

Given that with this case, I have never encountered, I had a job as easy as possible, with the expectation of unforeseen problems.

So that a standard size, which is in any store 2.25 m, I approached the most.

2️⃣ metal thickness.

Here there was a lot of reflection.

For sale I have seen metal roofing from 0.37 to 0.5 mm. Perhaps there are others, but apparently these are the most common thickness.

On the one hand, to see what a difference in fractions of a millimeter??? Although a significant difference in price.

It is clear that making a choice for your home, it is better not to save. And here I have not become much deeper and I chose a thickness of 0.5 mm.

3️⃣ thickness of the zinc coating.

This criterion may more important than the thickness. After zinc - this is what protects the base metal from corrosion. And the thicker it is, the more time will pass before the corrosion reaches the metal.

But there is one thing. In fact all the corrosion processes take place in the field of metal damage incurred during transport or installation. In mechanical damage longer important thickness of metal than zinc.

So, here I did not do many thoughts, and chose, which was 140 g / m2.

4️⃣ price of material and delivery.

Here it turned out an interesting situation.

I, logically, sought purchase options close to home (Leningrad region, 120 km from St. Petersburg).

But the cheapest option, and the price of metal itself, and most interesting, for the price of delivery, I found in St. Petersburg.

For me it was a true discovery ...

5️⃣ color and pattern.

The idea is that this item should be the first, but in fact, it was I was the last criterion. More specifically, taking into account all the above steps, all design options, I went through the fact that it was.

And here a matter of taste. My choice fell on the metal roofing Satin, dark brown color.
