Mwala wotentha wa HOLLEDndi gawo labwino kwambiri ndi gawo lotsimikizika kwambiri ndi gawo lofunikira kwambiri komanso kuchuluka kwamphamvu kwambiri. Imakhala ndi dzina lake chifukwa gawo lake la mtanda ndilofanana ndi kalata ya Chingerezi "H". Chifukwa gawo lililonse la zitsulo zooneka bwino limakonzedwa kumanja kumanja, zitsulo zowoneka bwino zimakhala ndi zabwino zambiri mbali zonse, monga kukana mphamvu, zomanga zosavuta, zolemera zowoneka bwino, ndipo zakhala zikugwiritsidwa ntchito kwambiri.

GRIG gawo lachitsulo ndi gawo lazachuma chachitsulo chokhala ndi zinthu zabwino, zomwe zimakonzedwa ndikupangidwa kuchokera ku gawo la I-gawo. Makamaka, gawo ili lofanana ndi kalata "H"

Nazi zambiri zokhudzana ndi mitengo ya H-

1. Miyeso: H-H-Manda amabwera kumayendedwe ambiri, ndi miyeso yosiyanasiyana kutalika, m'lifupi ndi masamba. Malishi okhazikika amachokera ku 100x100mm ku 1000x300mm.

2. Malaya: H-H-H-ikhoza kupangidwa ndi zida zosiyanasiyana monga chitsulo kapena zinthu zophatikizika.
