Balsa Triangles

Balsa triangles are used for airplanes, structures, bridges, and craft projects.  This particular triangular shape is called a 45x45x90 degree triangle, a right triangle, balsa tri, triangular balsa, and right angle balsa. Balsa can vary between 3# (foam weight) - 40# (oak weight) for pounds per cubic foot (lbs/cuft) but the most common densities are 8-16 pounds per cubic foot.

Include information about custom requests and density in the Order Notes message box at the end of this page:

  • Extra Light Balsa at (6 or less pounds per cubic foot) is 100% extra.
  • Light Balsa at (6-10 pounds per cubic foot) is 100% extra.
  • Medium Balsa at (10-14 pounds per cubic foot) is 100% extra.
  • Heavy Balsa at (14-19 pounds per cubic foot) is 100% extra.
  • Extra Heavy Balsa at (19+ pounds per cubic foot) is 100% extra.

Extra Light balsa is sometimes referred to as "Contest Grade" balsa because is used for ultra light airplane contests. It is usually discolored, very hard to find, very brittle, weak, and squishy.

Please note any custom weight classification that is narrower than the above listed weight categories will increase the cost of the required weight classification.

No preference as to a weight of balsa = no additional charge.
