Material to cover frame structure for OHT

[Vimal]

Hi,

I plan to go for a M.S Steel structure to support 2 numbers of 1000L overhead tanks. Due to structural constraint I can't construct brick wall to cover the structure. The shape of the steel structure will be triangular and will be supported by two perpendicular beams so as to avoid the load on the slab. As I can't construct brick wall I am looking for an alternative light weight material to cover the steel structure. One interior guy suggests to use shera board but another interior guy says shera board is not water proof. I am confused.

Any suggestions for a good weather-proof and water-proof material ?

Thanks

Have you looked at Marine paints? If these paints are good for marine applications, It should be more than adequate to handle water leaking from OHT.

Thanks. I will look into it. However, I need to decide on a light weight base material first.
