  • Highest in resistance to insect and decay.
  • Lifespan of over 75 years.
  • Low maintenance
  • No need to be dried for exterior uses

Cumaru deck

(Brazilian Teak decking)

24,800 psi

3540 lbs.

  • Over 50 years lifespan
  • Natural resistance to decay
  • Superb durability
  • Low maintenance
  • About 2/3 the price of Ipe

Cambara deck (Cambara Mahogany decking)

  • Light to medium brown hues
  • A coarse to medium open graining pattern

13, 080 psi

941 lbs

  • The ability to hold coatings well allows flexibility in colour design for different projects

Nice list and a sensible presentation, but whilst these species are harder, appear durable but what about consideration for the ability of these species to perform in different areas of the world. 

I have seen many of these tropical species underperform with regard to stability. With the exception of Ipe, the others certainly need a thicker material to maintain performance in stability. if this is not achievable due to limited supply then consideration should be for tighter joist layout (300mm C) and also much bigger fixings (min 5.5mm x 75mm)

There is far too much bad advice proffered to Landscapers and Contractors regarding these specialist materials... there should be much more information out there.
