Ochroma Pyramidale, womwe umadziwika kuti balsa tree, ndi mtengo waukulu, womwe ukukula mwachangu ku America. Ndi membala yekhayo wamtundu wa Ochroma. Dzina lakuti balsa limachokera ku liwu la Chisipanishi loti "raft".
Angiosperm ya deciduous, Ochroma pyramidale imatha kukula mpaka 30m kutalika, ndipo imayikidwa ngati nkhuni yolimba ngakhale kuti matabwawo ndi ofewa kwambiri; ndi mtengo wofewa kwambiri wamalonda ndipo umagwiritsidwa ntchito kwambiri chifukwa ndi wopepuka.
Ma Balsa Strips amatha kumamatidwa muzitsulo za balsa zomwe zimagwiritsidwa ntchito muzitsulo zamphepo monga zida zomangira.
Mitengo ya balsa nthawi zambiri imagwiritsidwa ntchito ngati maziko azinthu zophatikizika; mwachitsanzo, masamba a makina ambiri opangira mphepo ndi mbali ya balsa. Balsa wa chimanga ndi chinthu chokongola kwambiri pamasamba amphepo chifukwa ndi otsika mtengo komanso owundana mokwanira kuti apereke mphamvu zochulukirapo kuposa thovu, zomwe zimafunikira makamaka pamizu yopindika kwambiri ya tsambalo. Mitengo yamatabwa ya Balsa imadulidwa mumiyeso yodziwika, kugoledwa kapena kupangidwa ndi kerfed (monse muutali ndi m'lifupi, monga momwe zasonyezedwera, pa ma curve apawiri) ndiyeno amalembedwa ndikusonkhanitsidwa ndi ogulitsa oyambira kukhala zida.
40% yokha ya voliyumu ya balsa ndi chinthu cholimba. Chifukwa chimene chimatha kuima motalika ndiponso champhamvu m’nkhalango n’chakuti chimadzazadi ndi madzi ambiri, monga tayala lodzaza mpweya. Mafuta a balsa akakonzedwa, matabwawo amawaika mu uvuni ndipo amawasungamo kwa milungu iwiri kuti achotse madzi onse owonjezera. Ma turbine amphepo amapangidwa kuchokera ku matabwa a balsa omwe amakhala pakati pa tinthu tating'ono ta fiberglass. Kuti apange malonda, nkhunizo zimawumitsidwa pamoto kwa pafupifupi milungu iwiri, ndikusiya maselo opanda kanthu komanso opanda kanthu. Chiŵerengero chachikulu cha voliyumu ndi pamwamba pa maselo opyapyala opangidwa ndi mipanda, opanda kanthu amapatsa nkhuni zouma mphamvu zazikulu zolemera chifukwa maselo ambiri amakhala mpweya.
