Material Selection - FRP/Steel

Not enough information.

My initial response is, no. FRP is non-conductive, so a static charge will build up on the tower.

passington is quite correct: "you can, but you shouldn't" is great advice.

GA from me....

Also, why on earth would you want to do this in the first place? Steel telecom towers have been built for decades and are structural capable, light and cost effective. By the time you "beef-up" the FRP comtower to gain enough strength it'll be heavier and costlier than a comparable steel tower.

Don't forget that any telecom tower must be designed structurally for wind loadings, wind gust loadings, and snow and ice buildups in accordance with ASCE-07, if you're in the USA. If you're located elsewhere in the world use a comparable design standard.

What benefits are you hoping to achieve by substituting high tensile steel with FRP?

First I thank all of you for your valuable response!

I would like to build a 40m height telecom tower with in the weight of 2.5 Metric Ton

Is there any optimized way to use standard steel profiles? or pl suggest me any alternative material instead of steel!

Thanks in advance

Self supporting or guyed mast?

Why is the dead weight an issue? Rooftop?

Not a roof top tower, Its a Ground based Tower, the thing i have to design, Low weight structure with low cost

My customer given the weight target is 2.5 Metric Ton

Low weight structure with low cost....

Not gonna happen sport!

What exactly will be accommodated on this tower? Form should follow function.

Why the weight hangup? Are you lifting the materials by helicopter into the high Himalayas or launching it into orbit or what?

These guys claim to make something that answers the general description.

Very little detail and no pictures of real product.

Interestingly, "low cost" is not an attribute worthy of special mention there.

They say it is light weight not exactly how light (or heavy)

I am skeptical of their deflection claim. No units stated...not sure if it's metres or degrees... and anyway it is totally dependent on what is hanging on the tower and how hard the wind is blowing.

Ask them for a quote.

They also have carbon fibre products in their index. I didn't need to know badly enough to bother looking at these. Have a look for yourself.

I have seen carbon fibre monopoles. They aren't that tall and whip around too much for microwave links. They are definitely not low cost.

Would you travel in an aircraft with cheap light weight wings?

Lets see... 40 meters is approximately 120 feet. Judging from other responses, there AINT NO WAY!! I would consider climbing that sucker.

Tower design is a very specialized field, and at 120 feet I will leave that to the tower manufacturers who know what they are doing. That is not a home brew project. I am sure you do not want to be responsible for the death of an employee when the tower collapses with a person up top.
