Wood Decking
1
Durability of timber decking is the main concern of house owner. Especially, we have the extremely hot weather in Malaysia & always raining.
Here are some common timber species for Chengal, Belian (Not available anymore), Balau.
For timber deck, we usually recommend Chengal Timber. Why? Because it is #1 in Malaysia.

Yeah, Wikipedia say that. http://en.wikipedia.org/wiki/Neobalanocarpus
Belian also another alternative choice for decking. Belian is very durable timber which even better than Chengal. The supply is limited, and it also known as Borneo Ironwood.
With proper selection of timber and good installation, your decking can last for many decades.
(Checklist for select timber decking)
Our decking since Year 2016, will be Kiln Dry. Most of the Malaysia timber material for outdoor is not Kiln Dry. Their reason is the humidity of outdoor is high, that is no point to dry up the wood which is not truth.
When we cut down the green tree, moisture content of the wood is about 40%. Our outdoor humidity is about 16-20%. To gain strength and stability, wood must be below 20% MC (Moisture Content). Kiln Dry is always better way rather than Air Dry (leave wood outside let it slowly dry up below 20%MC). Air Dry process take 3-6 months depend on thickness and condition.
If timber is not dry enough, it will have problems of cupping, bend & twist.
