Container Recesses – How much Extra?
Posted by Aaron & Chris on 24 July 2007 at 09:42Hi all,
I’m wondering if anyone can help with this one.
I have been asked to apply a company name in vinyl to the roof of a shipping container. The container is 24ft Long and has 18 raised sections along it. The sections are raised 35mm and are 95mm wide with 245mm spaces between them. i know I need to allow extra for the recesses but I’m not sure how to work out how much I need.
The graphic is single colour so there is no layering up involved.
Any pointers would be much appreciated.
Cheers.
Aaron

I work that out that you need to extend to 123.5%, assuming the returns are at 90 degrees to the face.
-
I beg to differ:-
By my calculations I reckon you only need to extend to 120.6% (assuming there isn’t a full moon and the lettering is applied during a low tide *hair* )
-
120.58% That’s what I said.
(for some reason I added it up to 420 instead of 410)

Just had a look on the top of the container outside the workshop.
The raised sections have sides of closer to 45ยบ which means that each face will be approximately 49.497475mm long! (Using formula a= b/Sin 45ยบ) which means you need to allow a little more than 120.58%. Not sure what the tide state is but its sunny and warm!Steve

Fit the graphics flat bridging the recesses. then slit every bridge allowing the flaps of vinyl to fall into the recesses and apply down. you will be left with a gap. here, "using pre-cut" strips of vinyl. just lay them in and trim.
this is the quickest way. i once did about 140 metres of this on the face of a building about 50ft up using a cherry picker. NOT FUN! ๐ :lol1: -
Aaron, you only need to make the text longer if they want it at a certain length, if they just want to put their name on the top then you wouldn’t have to increase the length at all. How old is the container they want doing because I have done a few and the main problem with applying vinyl is the poor state of the paint. I would have a good check on condition before you apply anything.

Yeah but Martin, if he doesn’t extend then he is going to lose 20 percent of the width, effectively condensing the text. Which might look odd.

Andy, I have done a few and to be honest I just sized it to whatever height I needed and cut it as normal, did open up the kerning a little but that was all, when I applied the vinyl I used a centre hinge and worked out towards the ends, just applied it following the ups and downs didnt apply over high spots like Robert has said and they looked OK.
Thinking about it Andy I may just have been lucky with the fonts I used because I know what you mean now I stop to think about it. Maybe if I get another one to do at some point in the future I will do it differently now I know ๐ -

thanks for the replies guys,
They are more like 45degree recesses so I don’t know if it will look odd if I do what Rob has said, will it not look like there are extended parts of the wording where I have pieced it in?
I’m wondering if I could get away with doing it the way martin has suggested. The cabin is brand new and for a big project in London so it will be photographed from the air, it is being painted as we speak!
I’ll give it some thought.
Cheers.
Aaron.

I think that viewed from any angle, other than 90ยบ, the lettering is going to look a bit odd shaped because of the corrugations.
Viewed at 90ยบ you ‘visually’ loose about 10% of the length ie: the text will need to be expanded by that amount to compensate, however it’ll still look wrong from other angles, and not many styles will stand that amount of alteration to the shape.
I’d be inclined to expand it all by about 5% and start at the centre and work towards the ends as Martin says.Steve
