hi ,
in my country there is no PINE wood .....near to it is kerosene wood but very light and very sensitive to water and insects....my plan is to use gurjan wood for studs and kerosene wood for
slat resonator

is it ok?

You may be better off using steel. As a bonus, it generally has better sound isolating properties as well.

It does have better isolation properties, but everything matters. Fact is sound moves faster thru steel than it does wood, so that is not a reason to suggest to use it. The other fact is that most of the supporting data is based on a 24 inch stud spacing AND as often, using 2X6 type metal studs.

Now this might be or might not be a wall assembly that can support a ceiling, so that has to be taken into consideration.

Maybe that was what you meant....

so guys....what should i do.....by the way gurjan wood(most of the plywood is made by it) is very hard and durable and has no weather issues, a bit expensive than pine international value but steel is way more expensive.
my plan is to set up gurjan(uses in all practice pads) frame/studs with 16" spacing......so is gurjan is bad for that? what about mahogany(softer than gurjan )......and for slat
i have options:
mahogany/kerosine(pine look a like used for decoration, white finish )/gurjan
im attaching 2 pics of gurjan in-case it is a local name..............

I'm not familiar with those types of wood, but if that's all you can get where you live, then that's what it will have to be! Try to find out the structural characteristics of those types of wood, and compare them with types of wood that are more common in the Americas and Europe, to see which one will work best for you. See if you can find information on the following:

Modulus of Elasticity
Bending Strength
Bearing Strength
Shear Strength

Those seem to be the things you need to know, to figure out of that type of wood is structurally similar to other wood.

For the slats, it doesn't really matter what type you use, as long as it is fairly rigid and fairly massive (I wouldn't use balsa, for example! ), but I reckon that mahogany would look very nice for slats!

You have to use, whatever it is they use in your area of the world, for the studs, easy as that.

Some flexibility in a wooden assembly is good, known factors in relation to this flex is even better. Not knowing this, and I have to assume, based on my experience with plywood products, that this is a dense material with a tight grain since, from all the searching I have done over the past few minutes, it is part of plywood...maybe not a worldwide plywood, but germane to where you live.

Alhamdulillah

Thanx guys .i will try those info.one thing is this wood is very
Waity say a 10', 2x4fre is about 17-20kg.
So for seiling frame should I use thinner size like
1x4 ?in current plan all are 2x4 studs.

For long term use pine wood is better though it is not 100% safe against termites and other insects attack. Though Steel wood also a good option and pine wood is expensive I would like to suggest it. After giving [SPAM SUGGESTION REMOVED BY MODERATOR] pine wood lasts very long.
[SPAM SUGGESTION REMOVED BY MODERATOR] treatment ensures no termite or insect infestation for long time. For more information visit the [SPAM LINK REMOVED BY MODERATOR] team
