Iringi ye-Metallic VSP, ekwabizwa ngokuba yiringi ye-arc yangaphakathi, umsesane okhethekileyo kakhulu, yenziwe ngentsimbi yekhabhoni, insimbi engenasici, i-titanium alloy, ialluminiyam ialloy, ialloy yobhedu kunye nezixhobo zentsimbi.Izangqa ze-Metallic VSP zine-symmetry yejometri enengqiqo, ethi i-arc yangaphakathi isongwe ngokulinganayo ecaleni kwe-axial direction kwaye ithathelwe indawo elungelelanisiweyo.Olu yilo lunegalelo kwindawo eqhubekayo yokungabikho okuphezulu kakhulu kunye nokusabalalisa ngokulinganayo.
I-Metal VSP ring ineempawu zodonga oluncinci, umlinganiselo omkhulu we-void, ukuhamba okuphezulu, umthamo, ukuhla koxinzelelo oluphantsi kunye nokusebenza kakuhle kokwahlula.Ke uluhlu lwesicelo lwayo lubanzi kakhulu, ukomisa, ukufunxa, ukupholisa kunye nokuhlaziya inqaba kwimichiza ye-metallurgic, igesi yamalahle kunye neshishini lokwahlula umoya.
