Chubu chopanda msoko chimapangidwa ndi zitsulo zolimba zolimba popanda zowotcherera. Ma welds amatha kuyimira madera ofooka (omwe amatha kuwononga, kuwononga komanso kuwonongeka kwathunthu).

Poyerekeza ndi ma welded chubu, machubu opanda msoko amakhala ndi mawonekedwe odziwikiratu komanso olondola kwambiri potengera kuzungulira ndi kuwuluka.

Choyipa chachikulu cha mapaipi opanda msoko ndikuti mtengo pa tani ndi wokwera kuposa mapaipi a ERW ofanana kukula ndi giredi.

Nthawi yotsogolera ingakhale yotalikirapo chifukwa pali opanga ochepa a mapaipi opanda msoko kusiyana ndi mapaipi otsekemera (poyerekeza ndi mapaipi opanda phokoso, chotchinga cholowera cha mapaipi otsekemera ndi otsika).

Kuchuluka kwa khoma la chubu lopanda phokoso kungakhale kosagwirizana ndi kutalika kwake konse, kwenikweni kulekerera kwathunthu ndi +/- 12.5%.
