Trees routinely grow to 150 feet, and can reach 200 feet, with trunk diameters of 6 feet and

Usually air dries rapidly with very slight checking or warping. Material can be difficult to work
and difficult to saw. Hardness of material can cause a blunting effect to cutting edges. High
quality carbide and diamond tipped blades are recommended as well as pre-drilling when
surface fastening. Machining material generates a fine, yellow dust that may cause breathing
problems and dermatitis. Ipe is highly resistant to all insect and fungal attacks.
