Ua hana kūikawā ʻia ka lāʻau Pinus sylvestris i ʻano lāʻau anti-corrosion hou, nona nā hiʻohiʻona o ka pale ʻana i ka wā lōʻihi, ʻaʻole maʻalahi i ka haki, deform, pala, a ʻai ʻia i ka mu. Inā hoʻopili ʻia ka ʻili me ka pena wai wai waho maikaʻi e hana i kahi papa pale hilinaʻi a hoʻonui i ka hopena anti-corrosion o ka hoʻohana ʻana i waho, e lōʻihi ke ola o ka lawelawe, a maʻalahi ka mālama a paʻa.
Hiki ke hana mua i ka hana a me ka hana ʻana i ka hale hana, e mālama ai i ka manawa a hiki ke hoʻohana hou ʻia i ka wā e hiki mai ana. ʻO ke kalapona haʻahaʻa a me ka palekana kaiapuni, ka palekana o ka'ōmaʻomaʻo'ōmaʻomaʻo, ka mālamaʻana i ka ikehu, ke kū'ē a me ka lōʻihi, a me ke olakino a me kaʻoluʻolu. He ʻokoʻa ka hale glulam mai kahi hale paʻa i hoʻoikaika ʻia i ka mea e wela ai kahi ʻāpana lāʻau paʻa, akā ʻaʻole e wela.
ʻO nā papa a i ʻole nā ʻāpana liʻiliʻi me nā hua lāʻau like ʻole e hoʻopau mua ʻia a i ʻole ʻia i ka lōʻihi a i ʻole ka laulā e hana i nā laminates, a laila laminated a hoʻopili ʻia nā mea lāʻau i ka ʻaoʻao mānoanoa.
