SCH40 GI yeeb nkab hlau nrog cov qhov kawg grooved yog hais txog cov yeeb nkab hlau uas tsim los ua kom tau raws li tus qauv SCH40 rau phab ntsa tuab thiab ua los ntawm cov hlau galvanized. "GI" sawv cev rau "galvanized hlau" qhia tias cov yeeb nkab tau coated nrog ib txheej ntawm zinc los tiv thaiv nws los ntawm corrosion.
Lo lus "cov qhov kawg uas muaj qhov grooved" qhia tias cov qhov kawg ntawm cov yeeb nkab tau tsim los nrog cov qhov grooves los pab txhawb kev teeb tsa cov khoom siv sib txuas lossis cov khoom siv. Cov qhov kawg uas muaj qhov grooved feem ntau siv rau hauv cov tshuab tiv thaiv hluav taws, cov tshuab HVAC, thiab lwm yam kev siv uas xav tau kev sib txuas sai thiab ruaj ntseg.
