Gnee Exports 1198 Tuj Ntawm A709 GR.345W Hlau Phaj Thiab Cov Yeeb Nkab Rau Nyab Laj

Gnee (Tianjin) Multinational Trade Co., Ltd tau ua tiav exported 1198 tons ntawm ASTM A709 Qib 345W steel daim hlau thiab welded kav rau Nyab Laj, txhawb nqa loj choj thiab txoj kev loj.

Cov khoom xa tuaj no nthuav qhia Gnee lub peev xwm los muab siab -lub zog, huab cua- tiv taus steel rau cov txheej txheem tseem ceeb nrog kev nyab xeeb thiab kev ruaj ntseg.

Cov khoom xa tawm ua raws li ASTM A709 GR.345W, sib npaug rau EN 10025-5, thiab suav nrog steel phaj nrog thickness 5-50 mm, dav 1000–2500 mm, ntev 3000–18000 mm, thiab welded kav nrog OD 150 mm, thickness – 60 mm. 3000-12000 hli.

Cov phaj muaj qhov kub- dov tiav nrog cov tshuaj tiv thaiv- cov roj xeb, thaum cov kav dej muaj kev xaiv SA 2.5 sandblasting rau kev siv dej hiav txwv lossis sab nraum zoov.

Cov khoom sib xyaw ua ke muaj zog yield zog (Ntau dua lossis sib npaug rau 345 MPa), lub zog tensile (480-620 MPa), elongation (Ntau dua lossis sib npaug li 18%), thiab Charpy cuam tshuam toughness (Ntau dua lossis sib npaug rau 27 J ntawm -20 degree), muab kev ua tau zoo rau kev thauj khoom -cov kabmob 7} cov qauv, qhov kub thiab txias

Daim ntawv thov

A709 GR.345W steel daim hlau thiab cov kav dej welded yog siv rau hauv cov txheej txheem tseem ceeb thiab kev nyab xeeb rau cov choj thiab txoj kev loj:

Choj Girders thiab Deck Phaj

Cov phaj hlau tsim cov khoom tseem ceeb- cov kabmob girders, hla kab, thiab cov phaj phaj.

Cov kav dej welded yog siv los ua cov kab hollow thiab cov tswv cuab khov kho, txo qhov hnyav thaum tuav lub zog.

Huab cua steel ua kom ntev - lub sij hawm corrosion kuj nyob rau hauv ntug dej hiav txwv thiab dej ib puag ncig.

Highway Guardrails thiab Safety Barriers

Cov kav dej welded muab cov kev cuam tshuam -cov ntaub ntawv txhawb nqa rau txoj kev guardrails.

Ua kom muaj kev ruaj ntseg thaum lub tsheb sib tsoo thiab raug huab cua hnyav.

Cable Conduits thiab Service Platforms

Cov kav dej ua raws li kev txhawb nqa rau cov hluav taws xob cables, cov ncej teeb pom kev zoo, thiab kev nyab xeeb taug kev.

Txhim kho qhov ruaj khov nyob rau hauv kev vibration thiab kub variations.

Stormwater thiab Drainage Systems

Daim phiaj thiab cov kav dej tsim cov kav dej, cov kav dej, thiab cov qauv kev txhawb nqa dej nag.

High corrosion kuj thiab txhua yam kev ua tau zoo ua kom lub neej ua haujlwm ntev nrog kev saib xyuas tsawg.
