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. 1 Pacific 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: 2 WORKING STRESSES IN FLEXTURE - POUNDS PER SQUARE INCH Dry Places_______ Under Cover In Wet Places _______Outside not in contact with groundTeak 1300 lbs 950 lbs 1100 lbsBalau 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. __________________________________________ 1Timber Species of Tropical Hardwoods, STTP, 1st Edition, 19962 Malaysian Timber Industry Board, Second Reprint, November 1994
