Loaʻa iā ia nā hiʻohiʻona o ke kaumaha māmā, ikaika kiʻekiʻe, linearity maikaʻi, ʻaʻole maʻalahi i ka deform, ka pale ʻana o ka ʻili i ka wai a me ka waikawa a me ka alkali, etc. hiki ke hoʻohana ʻia me nā huahana ʻōnaehana formwork ʻoihana ma ka home a ma waho.

2. Hiki ke hoʻohana nui ʻia i nā ʻōnaehana formwork like ʻole e like me ka ʻōnaehana formwork horizontal, ʻōnaehana formwork vertical (wall formwork, column formwork, hydraulic climbing formwork, etc.), variable arc formwork system and special formwork.

3. ʻO ka lāʻau I-beam straight wall formwork he mea hoʻouka a hoʻokuʻu i ka formwork, kahi maʻalahi e hui. Hiki ke hōʻuluʻulu ʻia i loko o nā formworks o nā ʻano nui i loko o kahi ākea a me ke degere, a hiki ke maʻalahi i ka noi. He kiʻekiʻe ka rigidity o ka formwork, a he mea maʻalahi ke hoʻohui i ka lōʻihi a me ke kiʻekiʻe. Hiki ke ninini ʻia ka formwork ma kahi kiʻekiʻe ma mua o ʻumi mau mika i ka manawa. Ma muli o ka māmā o ka paona i hoʻohana ʻia, ʻoi aku ka māmā o ka formwork holoʻokoʻa ma mua o ke kila kila ke hui ʻia.

4. ʻO nā ʻāpana huahana ʻōnaehana i hoʻohālikelike ʻia, hiki ke hoʻohana hou ʻia, a hoʻokō i nā koi palekana kaiapuni.
