S350 GD
Sstands rau Structural Steel. 350 qhia qhov tsawg kawg nkaus tawm los ntawm cov hlau.
350txhais tau hais tias cov hlau muaj qhov tsawg kawg nkaus tawm lub zog ntawm 350 MPa (megapascals, megabulls ib square millimeter), uas yog qhov siab tshaj plaws uas cov hlau tuaj yeem tiv taus ua ntej deformation.
GDtxhais tau hais tias cov hlau yog Galvanized Steel, piv txwv li cov saum npoo ntawm cov hlau tau kub -dip galvanized los txhim kho nws corrosion kuj.
