Sonke siyakwazi i-Q235 ne-Q345 izinto ezimbili ezibalulekile ze-scaffolding.
Uyazi ukuthi yini umehluko wabo.
Q235kuyinto yensimbi ebonakalayo yekhabhoni esetshenziswayo kulo lonke elaseChina. Yaziwa nangokuthi i-Q235A, Q235B, Q235C, ne-Q235D. Njengoba inensimbi emnene, isetshenziswa ekukhiqizweni ngaphandle kokwelashwa okushisa. I-q ikhokha iphuzu lesivuno, futhi abangu-235 bakhombisa amandla okuthenga.
Q345Ingabe impahla yensimbi. Kuyinsimbi ephansi ye-alloy (C <0.2%), esetshenziswa kabanzi emabhuloho, izimoto, imikhumbi, ezakhiweni, imikhumbi yokucindezela. I-Q imele isivuno salokhu okuqukethwe, ngemuva kwe-345, isivuno sisho inani lalokhu, cishe ama-345. Futhi sizokwandisa ubukhulu bezinto ezibonakalayo nenani lesivuno lalo liyancipha.
Q345A, Q345B, Q345C, Q345D, Q345E. Lokhu ukwahlukaniswa kwesigaba okumele ikakhulukazi umthelela wokushisa ahlukile kuphela!
Ileveli ye-Q345A, akusho ukushaqeka;
Ibanga le-Q345B lingumthelela wokushisa kwegumbi lama-20 degrees;
Ileveli ye-Q345C, ingu-0 degree umthelela;
Ileveli ye-Q345D ngu-20 degree umthelela;
Ileveli ye-Q345E-40 degrees Impact.
Umthelela wokushisa okuhlukile, inani le-shock ahlukile. Epuletini, icala lochungechunge oluphansi lwe-alloy. Ezintweni eziphansi ze-alloy lapho izinto ezinjalo zivame kakhulu.
Q235 no-Q345 umehluko
1. Umehluko womkhawulo wamandla wesivuno:
A: Isivuno se-Feand Limit Q235 ngu-235MPA,
B: ukukhiqiza umkhawulo we-Q345 u-3455 uneminyaka engama-345mpa (Q yezinhlamvu zesiShayina okusho ukuthi "Bend", yiliphi inani elifanekisela amandla okuvutha angemuva (
2. Okuqukethwe okubili okuhlukile kwe-alloy:
A: Q235 I-Carbon Steel ejwayelekile, i-Q235 iyinsimbi ye-carbon, i-Q235- yesakhiwo, isikhungo samandla afunwa kancane noma izingwegwe, izinduku, izinduku
B: q345 Low-Alloy Steel, Q345 Insimbi Ehlelekile-i-Alloy Steel, i-Q345- Izakhiwo ezinhle zemishini, izimoto eziphansi, ezisetshenziswayo, izitsha zensimbi, amabhuloho, njll. Ukumelana nomthwalo oshukumisayo Ukusetshenziswa, kungasetshenziselwa zonke izinhlobo zensimbi engenhla kwezindawo ezibandayo.
