SCH40 GI steel yeeb nkab nrog grooved xaus yog hais txog cov yeeb nkab steel uas yog tsim los ua kom tau raws li SCH40 tus qauv rau phab ntsa tuab thiab yog ua los ntawm cov hlau galvanized. Lub "GI" sawv cev rau "galvanized hlau" qhia tias cov yeeb nkab tau coated nrog ib txheej ntawm zinc los tiv thaiv nws ntawm corrosion.
Lo lus "grooved ends" qhia tias cov yeeb nkab kawg yog tsim los nrog cov grooves los pab txhawb kev txhim kho cov khoom sib txuas lossis cov khoom sib txuas. Grooved xaus yog feem ntau siv hauv kev tiv thaiv hluav taws, HVAC systems, thiab lwm yam kev siv uas yuav tsum tau muaj kev sib txuas ceev thiab ruaj ntseg.
