1. Specific Gravity: Rau steel hlau ropes nrog tib txoj kab uas hla, qhov siab dua qhov tshwj xeeb gravity, qhov zoo dua.
2. Core Strength: Cov tub ntxhais muaj zog dua thiab siab dua qhov tshwj xeeb lub ntiajteb txawj nqus, qhov zoo dua qhov kev txhawb nqa rau cov hlua sab nrauv, thiab qhov zoo ntawm cov hlua hlau.
3. Khoom siv: Cov khoom siv yog hais txog qib steel thiab lub zog. Qhov siab dua cov qib steel thiab lub zog siab dua, qhov zoo ntawm cov hlua hlau zoo dua.
4. Ib txoj hlua xoob me ntsis tom qab txiav yog qhov zoo. Ib txoj hlua hlau nrog lub suab ntev ntev yog qhov zoo dua li ib qho nrog luv nteg suab.
5. 316 stainless hlau xaim hlua muaj zog corrosion kuj tshaj 306 stainless hlau xaim hlua . 306 muaj zog corrosion kuj dua kub -dip galvanized hlau hlua. Kub-dip galvanized hlau hlua yog qhov zoo dua li electro-galvanized hlau hlua. Nylon-coated steel hlau hlua yog qhov zoo dua li PE-coated steel hlau hlua. PE-coated steel hlau hlua yog qhov zoo dua li PVC-coated steel hlau hlua. Coated steel hlau hlua muaj zog corrosion kuj tshaj galvanized steel hlau hlua.
