The sapwood and heartwood are yellowish to white-red color. Under circumstances it withstands weather conditions and it is sickly to insects and fungi infestation.
Physical Properties: It is of soft to medium hardness, moderately lightweight, elastic and solid. It has good stability, it shrinks a little, is good at drying and easy to process. The cross section gives generally oval knots.
True density at 15% humidity: 0.47 g/cm3
The contraction rate % in 1% change in moisture content in the direction of the heartwood is from 0.12 to 0.19% and in the direction of the annual growth rings is from 0.24 to 0.33%.
The pines are harder and heavier than the firs.
Without diametric (radial) shakes. Few, small and healthy knots are allowed, limited cyanosis, few and small resin pockets, few and small shakes/ wanes.
Allowed: Small, healthy and a few dead knots, extensive cyanosis, unlimited resin pockets, few lines, extreme stretch shakes (perhaps through-going) with length not greater than the width of sawn timber and small wanes.
Allowed: Few shed knots of average size, healthy and unlimited discoloration up to 40% of the surface, resin of average size in a small number, shakes and wanes of an average size and limited insect infestation.
