WHAT IS BALAU

 

Balau is a tropical hardwood of the family Dipterocarpaceae. Balau is a very dense tightly grained wood that is heavily laden with rich tropical oils and resins. Balau’s texture is very fine and even. Our Yellow Balau looks very much like teak in color.  Although, very similar in characteristics to Teak, we enjoy working with Balau for its durability, strength, seasoning and mechanical properties. For centuries Balau has been used for shipbuilding, heavy-duty furniture, heavy construction and coveted for it’s excellent strength and weather resistant qualities. Over the years, teak has been more popular than Balau because of its availability. However, in recent years, teak has been over-harvested and the price has skyrocketed. As a result, teak is now plantation grown.  Balau is also a responsibly managed species and although it’s mechanical properties are superior, Balau has not experienced the overpricing that teak has. Below you will find a property comparison between teak and balau.

1Pacific tropical hardwoods are categorized accordingly:

Heavy Hardwoods

Medium Hardwoods

Light Hardwoods

Durability: 

Group 1 Very Durable

Group 2 Durable……………………….<Balau>

Group 3 Moderately Durable………….<Teak>

Group 4 Not Durable

Strength: 

Group A    Extremely Strong…..............<Balau>

Group B    Very Strong

Group C    Strong………………........…<Teak>

Group D    Weakest

With the above in mind, Teak is rated as a Medium Hardwood and Balau a Heavy Hardwood. With regard to durability, Teak has a durability rating of Group 3 or Moderately durable and Balau is rated a Group 2, Durable. In the strength category, Teak is rated a Group C or Strong whereby Balau is rated the very best as a Group A or Extremely Strong.

 

To bring this all into a relative perspective one needs to analyze the working stress data per category as follows:

2WORKING STRESSES IN FLEXTURE - POUNDS PER SQUARE INCH

                                          Dry Places_______ Under Cover In Wet Places _______Outside not in contact with ground

Teak                       1300 lbs                    950 lbs                                  1100 lbs

Balau                     2600 lbs                  1950 lbs                                  2250 lbs

 

In summary, Balau has far superior strength characteristics and is a more durable wood than teak by at least a factor of two. 

As Balau’s popularity continues to grow, unfortunately so does the price, but for now we enjoy the undervalue pricing of this beautiful and strong tropical hardwood.
