Q235 asye se yon asye estriktirèl kabòn plenn ak yon fòs sede nan apeprè 235 MPa, ki ka varye depann sou epesè materyèl. Deziyasyon "Q" reprezante pwen sede materyèl la, pandan ke "235" endike fòs sede apwoksimatif li an megapascal.
Tiyo asye galvanize Q235 pa mande pou tretman pwosesis espesyal, tankou prechofaj oswa tretman chalè apre -soude, sa ki fè yo koute-efikas ak efikas pou itilizasyon endistriyèl.
Tiyo sa yo montre ekselan solidite, soudabilite, ak plastisit, kenbe fòs menm anba koube nan tanperati ki ba. Q235 tiyo asye galvanised yo lajman aplike nan konstriksyon, jeni, ak endistri mekanik.
Itilizasyon komen yo enkli bilding faktori, ba asye, gwo fò tou won, chodyèr, pon, resipyan, otomobil, ak divès kalite estrikti soude. Yo sèvi tou kòm konpozan mekanik serye.
Tout tiyo GI Q235 yo sijè a kontwòl kalite strik, ak sètifika tès ki disponib ak enspeksyon twazyèm pati -pou asire pèfòmans nan divès kondisyon anviwònman an.
