Magetsi apansi panthaka amabwera mosiyanasiyana kuti agwirizane ndi zochitika zosiyanasiyana zamagwiritsidwe ntchito komanso kapangidwe kake. Nazi zitsanzo zodziwika bwino:
Magetsi ozungulira apansi panthaka:
Ma diameter wamba amaphatikizapo Φ50mm, Φ65mm, Φ80mm, Φ100mm, Φ150mm, Φ180mm, ndi Φ200mm.
Kutalika nthawi zambiri kumachokera ku 45mm mpaka 250mm.
Magetsi apansi panthaka:
Kukula kumayambira 100x100mm mpaka 300x300mm yayikulu.
Makulidwe nthawi zambiri amachokera ku 50mm mpaka 90mm.
Magetsi apansi panthaka amakona anayi:
Utali-ku{1}}kuchuluka kwake kumasiyanasiyana, monga 200x80mm, 300x90mm, 600x100mm, ndi 1000x100mm.
Kutalika nthawi zambiri kumachokera ku 60mm mpaka 70mm.
Magetsi Opangidwa Mwapadera Apansi Pansi:
Kuphatikiza pa mawonekedwe ozungulira komanso masikweya, palinso-zowunikira zapansi panthaka zokhala ngati zopindika, monga zopindika ndi ma polygonal, ogwirizana ndi zosowa zenizeni.
Kukula kulikonse kumayenderana ndi ma wattages osiyanasiyana komanso mawonekedwe ogwiritsira ntchito. Mwachitsanzo, kuwala kochepa pansi pa nthaka kungakhale koyenera kuunikira kadera kakang'ono monga kanjira kapena m'mphepete mwa bedi la maluwa; pamene yaikulu ikhoza kugwiritsidwa ntchito kumadera akuluakulu omwe amafunikira kuwala kwamphamvu, monga ma plaza ndi malo oimika magalimoto.
Kuonjezera apo, kukula kwapadera kwa kuwala kwapansi pa nthaka kumakhudzanso kukula kwa kutsegula (ie, kukula kwa dzenje losungidwa pansi), lomwe ndi lofunika kwambiri pakuyika. Kuonetsetsa kuti kukula koyenera kwa kuwala kwapansi panthaka kumasankhidwa komanso kuti miyeso yotsegulira imayesedwa bwino ndikukonzedwa ndizofunikira kuti pakhale kuyika kosalala.
