Fixing to galvanised steel frame

[i=p/u]

Have a guy asking me to wire lights to galvanised frame car wash , I was thinking PVC pipe to adaptable boxes is only way I can see, would self tappers work , cheers

 

[thelondonway]

self tappers would be fine

How thick are the struts / cross supports that you want to fix to , it will almost definitely be OK but will it affect its structural integrity .

Have you got any pictures of it ?

How will self tapping screws affect structural integrity?? This is just another old wives tail i'm afraid!!

Holes drilled into structural steelwork need to be of quite a size, with nothing but cables passing through to have any effect to it's integrity. Holes drilled and tapped for bolt, or holes with correct sized nut & bolt will have virtually Zero effect!! Been all through this with the various project Structural Engineers on every project i've ever worked on, never been refused permission yet!! lol!!

The conduit and boxes will need sealing well as the water mist gets into everything.

Best to drive thro one and see how it's noramlly done.

I totally agree with you to be honest !

But my thoughts were more in years to come , the manufactures have gone to the trouble of galvanising it instead of just painting it so i assume it is intended for a reasonably hostile environment .
Not knowing for sure at the moment what environment it is going in , maybe self tappers fixed into a not so well designed piece of equipment might not be the first choice ?
In the past we have worked on a local landfill site and have carried out repairs on the the sites exiting truck wash , along with the wash chemical and the leachate it was not as structural sound as when it went in , to say the least .

It is all very well for Tom Dick and Harry to just blindly agree with the op's first thoughts , but some times a little more info does help .


No offence meant to thelondoway, with the last comment .

Edit; Or of coarse you Engineer54 , as i do totally agree with your point as well .

Well just to let you know , it was roughly 4x4 steel frame and I fixed cable tray along it fixing with self tapping hex heads And installed 25c x1.5 mm and cat 6 cable tied.. Job done

PVC Pipe, Adaptable boxes and get some Dielectric Gel from ebay......


can you have the option to fit Low Voltage LED'S for the lighting?
