Building own car wash - Steel hollow section

[MackanM]

Hello

I am going to build my own GDS car wash and need help with the construction.

All steel is hollow section.

1. The posts are 100x100 mm - UNKNOWN thickness

2. The roof (7 steel hollow sections running lengthwise) UNKNOWN size and thickness.
All I know is that they should be rectangular. I've looked at existing washes and they seem to be half the width of the posts.

Can anyone help me with points 1 and 2?

I believe it is 120x60 but I am uncertain. Sheet metal roof and the lowest class of snow it is.

Why 100x100? It's insanely oversized. The construction is not stabilized either.

Drove past a car wash, a major player, and they had it that way with a pad of 20x20 cm where the post stood on.

What else should it be? Don't know the thickness either.

By the way, it wasn't the intention to sound so negative, just mean that you have to pay for a lot of unnecessary steel.

No, I understood that, but I thought you had a solution haha! or an answer to how it should be!

You need to calculate it to know, snow and wind loads. It might be difficult to go through the regulatory process if you don't have someone dimension this? In the end, you need to submit a construction certificate.

It takes a few hours to design a structure like this.

Okay

check your PM

I would probably remove the ceiling joists and place load-bearing metal sheets along the length of the house. Some diagonal braces are also needed to support it.

Exactly, too much pressure in the longitudinal direction of the building, so the whole beauty folds down like a Z.

OK. Googling on the plåt seems to suggest it's cheaper and better but I still need something stable to attach the 360 spray arm that the hose is connected to?

Should I have 1 or 2 that go along the entire building in the middle of the roof that I use to screw on the 360 arm?

 

[MackanM]

the slope of the roof is 7 degrees

Yep, I've seen pictures of carports that ended their days that way. They usually get cleaned up quickly because it's a bit embarrassing if it's newly built
