Raws li lub Hoobkas ncaj qha nrog 20 xyoo ntawm kev tsim steel hlau, GNEE Steel khoom siv EN 10346 rawsS550GD galvanized steel ntawv thiab phajntawm Hoobkas nqi. Hauv phau ntawv qhia no, peb yuav piav qhia tag nrho cov kev qhia tshwj xeeb thiab pab koj suav cov nqi tsaws tag nrho suav nrog kev thauj khoom thiab kev lis kev cai.
Galvanized steel yog hlau nrog zinc txheej los tiv thaiv corrosion, siv hauv kev tsim kho, tsheb, thiab hluav taws xob kev lag luam. Cov qib feem ntau suav nrog DX51D (kev siv dav), S350GD (lub zog nruab nrab), thiab S550GD (siab zog). S550GD sawv tawm rau nws 550MPa yam tsawg kawg nkaus lub zog tawm los, zoo tagnrho rau kev thauj khoom- cov ntawv thov kabmob.
