ASTM A36 carbon steel phaj muaj carbon ntau li ≤0.26% (ua raws li ASTM A36 qauv), manganese ntau li ≥0.75%, thiab lees tias lub zog yield ≥250MPa (qhov ntsuas nruab nrab 280MPa, tshaj lub teb chaws qauv Q235 ntawm 205MPa), thiab tensile strength 400-550MPa. Lub zog ntaus thaum kub -30℃ yog ≥27J (GB/T 229 qauv), thiab kev tiv thaiv hluav taws muaj lub zog khaws tseg >65% thaum 600℃ (EN 1363-1 certification).
Nws qhov zoo ntawm tus nqi yog qhov tseem ceeb: tus nqi ib ton tsuas yog 1/5 ntawm stainless steel, thiab tag nrho cov nqi tsim kho kom tsawg 35%; 8mm tuab tuaj yeem hloov tau cov phaj 10mm, txuag tau $8,200 hauv kev thauj khoom rau ib qhov project (load capacity nce 15%).
Peb muab ASTM A36 carbon steel phaj flame cutting kev pab (tolerance ±0.8mm, ua raws li ISO 9013 Class 2 qauv) thiab laser leveling (flatness ≤1mm/m²). Qhov nto yog shot blasted rau Sa 2.5 (GB 8923 qauv) thiab pre-coated nrog anti-rust oil (film thickness 8μm, khaws cia kom tsis txhob xeb txog 6 lub hlis). Peb muab CAD nesting optimization pub dawb (material utilization rate nce 18%) thiab weld groove prefabrication (ua raws li AWS D1.1 bridge welding specification).
Peb siv integrated continuous casting thiab rolling txheej txheem (rolling speed 12m/min), thiab tswj cov austenite grain size (ASTM 7-8 grade) nrog cov fully automatic controlled cooling line, ua kom tau qhov zoo tshaj plaws hauv kev lag luam nrog thickness tolerance ±0.15mm.
Peb muaj peev xwm tsim 500,000 tons txhua xyoo, thiab 50,000 tons nyob tas li (nrog rau 6mm/10mm/20mm cov loj uas muaj npe), txhawb kev xa khoom txhua hnub txog 1,200 tons rau cov xaj ceev kom tau raws li qhov xav tau ntawm cov project loj. Txhua pawg raug kuaj nrog spectrometer kom (C/Mn/S/P yuam kev <0.01%) and universal testing machine mechanical test (with yield/tensile/elongation report).
Kev xaj 100 tons ASTM A36 carbon steel phaj tau txais 5% discount, 500 tons xaj tau tus nqi ruaj khov rau cov neeg tseem ceeb (8% qis dua tus nqi nruab nrab) + khaws cia pub dawb 30 hnub. Yog tias khoom muaj teeb meem zoo, peb yuav them nyiaj tag nrho. Muab cov ntawv qhia ntau yam kev kuaj khoom.

Cov Lus Nug Feem Ntau
Q: Koj puas tuaj yeem muab daim ntawv pov thawj keeb kwm (CO) rau kev tshaj tawm?
A: Yog, peb tuaj yeem muab CO, nrog rau lwm cov ntaub ntawv xws li commercial invoices thiab packing lists uas xav tau rau kev tshaj tawm.
Q: Koj txoj cai li cas rau kev thov rov qab los yog hloov khoom?
A: Yog tias khoom muaj teeb meem zoo los ntawm peb, peb yuav npaj hloov lossis them nyiaj rov qab hauv 30 hnub tom qab tau txais.
Q: Ntev npaum li cas los tsim ib qho kev xaj tshwj xeeb nrog cov specifications tshwj xeeb?
A: Feem ntau yuav siv 25-30 hnub, nyob ntawm qhov nyuaj ntawm kev tsim. Peb yuav lees paub lub sijhawm tiag tom qab soj ntsuam koj cov kev xav tau.
Q: Koj puas muab kev pab technical rau kev teeb tsa lossis siv khoom?
A: Yog, peb pab neeg technical tuaj yeem muab cov lus qhia installation, video tutorials, lossis txawm yog kev pab ntawm qhov chaw yog tias xav tau.
