Khoom npe:Choj Hlau Hlau Phaj
Lub hauv paus rau phau ntawv
Lub cim hlau steel yog cov txheej txheem hluav taws xob hnyav nrog cov khoom siv hluav taws xob thiab cov ntaub qhwv ntsej muag, thiab cov huab cua tsis zoo, thiab cov tsiaj tsis muaj zog, Tus choj kav hlau ua kom muaj kev nyab xeeb ntev thiab ua haujlwm hauv txoj kev loj, thiab neeg taug kev choj.

Cov qib kev cai, cov tuab, thiab qhov loj me muaj kom haum rau cov qauv tshwj xeeb .
Nta & Qhov Zoo
High Fatue Resistance:Superior sugnessness minimizes ua kom tawg ua rau hauv qab cov tsheb thauj khoom hauv qab .
Txhim Kho Huab Cua:Weathernesant Alloy xaiv (e {. g}}}, corten) txo kev txhim kho corrosion hauv chaw ua si sab nraum zoov.
Precision Qis:Nruj flatness tivtisive paub tseeb tias muaj cov kabmob sib chwv thiab yooj yim ntawm vuam lossis bolting .
Zoo heev Weldability:Tswj kev txhawb nqa kev ntxhov siab thiab qis dua cov kev nyuaj siab txhawb kev ruaj khov, cov welds dawb .
Zoo ib yam zoo:100% kev xeem ultrasonic thiab tshuab kho tshuab tuaj yeem lav tau kev ua haujlwm rau Chris code .
Cov Ntawv Thov
Choj Decking:Hnav-resistant sab saum toj daim hlau rau asphalt lossis qhob overlays .
Main Girders & Cov Hlaws:Longitudinal load-cov kabmob ceg .
Hla Nraum & Diaphragms:Transverse stiffeners uas xa cov khoom thauj khoom thiab tswj cov geometry .
Cov Kabmob Lub Rooj Hlau:Interfaces ntawm supersture thiab bearings .
Kho & Rehabilitation:Thaj phaj rau lawj lossis girder kho rau cov choj uas twb muaj lawm.
Ntim & Xa Tawm
Ntim:
Daim hlau nraus nrog ntoo lossis polymer spacers; npoo tiv thaiv nrog cov hlau sib ceg hlau .
Tua-blast ntxuav los yog roj raws li teev; banded thiab ntsws-qhwv rau corrosion tiv thaiv .
Bundles thauj khoom ntawm cov dej num hnyav lossis khoom pallets rau kev thauj khoom nyab xeeb .
Lub sij hawm ua:Cov kev tsim khoom raug thiab cov zaub mov xa tuaj tsis pub dhau 25-35 hnub tom qab kev txiav txim; Cov sijhawm teem sijhawm kom ceev nraus muaj rau cov phiaj xwm kev tseem ceeb tshaj plaws .
