Ma mesh a zitsulo zowonjezera amadulidwa ndikutengedwa kuchokera ku mbale zazitsulo zapamwamba kwambiri, alibe ma solder, mphamvu zambiri, ntchito yabwino yotsutsana ndi kukwera, mtengo wapakati komanso kugwiritsa ntchito kwakukulu.
Ukonde wachitsulo wokulitsidwa uli ndi mawonekedwe okongola komanso kukana kwa mphepo.Pambuyo pa zokutira zokhala ndi malata ndi pulasitiki, zimatha kutalikitsa moyo wautumiki, kuchepetsa mtengo wokonza, ndikukhala ndi mitundu yowala.Ndipo ndizosavuta kuziyika, zosavuta kuwononga, malo okhudzana ndi ang'onoang'ono, sikophweka kukhala fumbi, ndipo akhoza kukhala oyera kwa nthawi yaitali.Ndilo kusankha koyamba kwa engineering yokongoletsa msewu.
