S280GD Galvanized hlau
Galvanized steel yog ib qho tseem ceeb ntawm cov khoom siv niaj hnub hauv tsev thiab kev tsim khoom, lees paub rau nws zoo heev tiv thaiv corrosion. S280GD galvanized steel, tshwj xeeb, sawv tawm raws li cov khoom siv ntau yam, muab qhov sib npaug ntawm lub zog thiab kav ntev.
S280GD yog ib qho muaj zog, qis- alloy structural steel uas tau siv dav hauv kev tsim kho thiab tsim khoom. Nrog rau qhov tsawg kawg nkaus tawm lub zog ntawm 280 MPa, nws yog qhov nyuaj txaus rau kev xav tau cov haujlwm ua haujlwm. Qhov kub-dip zinc txheej muab kev tiv thaiv zoo tshaj plaws tiv thaiv corrosion, lav kev ua haujlwm ntev. Ua tsaug rau qhov kev sib xyaw ua ke ntawm lub zog thiab kev tiv thaiv, S280GD yog qhov zoo tshaj plaws rau cov txheej txheem thav duab, vov tsev, thiab lwm yam hnyav - daim ntawv thov.

Nta
S280GD galvanized steel ntawv / daim hlau tuaj yeem nqa cov txiaj ntsig hauv qab no rau koj qhov project:
Ua kom kawg- Cov txheej txheej galvanized tiv thaiv xeb, muab koj cov khoom siv ntev dua -.
Yooj Yim Ua Haujlwm Nrog- Txawm hais tias koj xav tau txiav, khoov, lossis vuam, nws yooj yim rau kev ua haujlwm.
Muaj zog thiab ruaj khov- Muab lub zog zoo los daws cov ntawv thov thiab ua kom muaj kev ntseeg tau ntawm cov qauv.
Huab cua-Resistant- Ua tau zoo nyob rau hauv cov xwm txheej tawv, tiv taus ya raws thiab sab nraum zoov.
Lub teeb thiab siv tau- Nws yog qhov sib zog dua li ntau txoj hauv kev, uas pab nrog kev thauj mus los thiab kev teeb tsa.
Smooth thiab npaj siv-Qhov saum npoo yog huv si thiab du, zoo tagnrho rau kev pleev xim lossis siv tam sim.
Zoo heev- Muab kev ua tau zoo ntawm tus nqi- tus nqi zoo, ua rau nws xaiv qhov ntse rau ntau qhov haujlwm.
S280GD Galvanized Steel nqi
Tus nqi ntawm S280GD + Z galvanized steel kauj yog nyob ntawm cov khoom siv, kev qhia tshwj xeeb, kev kho deg thiab tus neeg muag khoom, tus nqi txiav txim yam tsawg kawg nkaus yog 650-850USD ib tuj, lub thicker zinc txheej, tus nqi siab dua. Lub caij no, tus nqi rau qhov sib txawv ntawm qhov chaw xws li xoom zinc, me me zinc, ntiv tes tiv thaiv, chromate passivation, thiab lwm yam kuj txawv, yog tias koj xav tau, koj tuaj yeem tso cov lus qhia rau peb paub, thiab peb yuav muab cov lus qhia pub dawb rau koj.
