How is Chinese hot-rolled steel plate suitable for infrastructure projects in Central America?A complete analysis of key grades such as Q345B

Kub-dov hlau phaj: Cov yam ntxwv tseem ceeb ntawm lub hauv paus kev lag luam
Kub dov steel phajyog tsim los ntawm billets los ntawm high-temperature dov. Nws khav theeb qhov zoo ntawm qhov dav ntawm lub zog adaptability thiab muaj zog formability, ua rau nws dav siv nyob rau hauv lub tsev, infrastructure, machinery manufacturing, thiab lwm yam teb.

Raws li cov ntaub ntawv los ntawm Latin American Steel Association, Central America cov hlau ntshuam suav nrog 11% ntawm Latin American tag nrho, ib nrab ntawm cov tuaj ntawm Tuam Tshoj.

Cov ntaub ntawv tseem ceeb yuav los ntawm Tuam Tshoj hauv Central America thiab lawv daim ntawv thov

(I) Tsawg-alloy, siab zog steel: Q345B
Q345B yog cov khoom siv "yuav tsum muaj" rau Central American infrastructure tej yaam num. Nrog lub zog tawm los ntawm 345 MPa, nws ua ke zoo heev weldability thiab cuam tshuam tsis kam. Nws ua raws li GB / T cov qauv thiab tau lees paub ISO9001.

Hauv ob qhov dej phwj loj loj nthuav dav hauv Nicaragua, tag nrho ntawm 1,471.26 tons ntawm Q345B kub dov Larsen steel ntawv pawg tau yuav hauv ib qho mus. Cov no tau siv rau lub hauv paus kev tsim kho ntawm 87.2 mais ntawm cov kav dej phwj tuaj, tsib lub chaw tso dej, thiab ib qho chaw kho dej phwj. Muaj nyob rau hauv 9m, 12m, thiab 15m ntev, lawv zoo kawg nkaus haum qhov xav tau qhov tob ntawm qhov project hauv av. Lub ntsiab kom zoo dua ntawm cov khoom no yog nws cov qauv kev ruaj ntseg nyob rau hauv tropical, rainy huab cua, thaum muab ib tug nqi-kev ua tau zoo piv deb tshaj ntawm cov khoom zoo sib xws hauv zos.

(II) High-Quality Carbon Structural Steel: SPHT1 thiab SAE Series

SPHT1: Raws li cov hlau stamping raws li Japanese JIS tus qauv, SPHT1 tau dhau los ua qhov kev xaiv zoo tshaj plaws rau kev tsim kho vaj tse hauv Dominican koom pheej vim nws cov yas siab thiab tawv. Royal Steel yav dhau los kho 900 tons ntawm SPHT1 kub dov kauj rau Dominican cov neeg siv khoom. Tom qab optimizing stamping tsis thiab ua ntxiv rau hauv cov kav dej, SPHT1 tau siv rau hauv kev tsim kho hauv nroog. Nws lub zog sib npaug thiab tsim tau ua rau nws tsim nyog rau cov raj xa dej ntau zaus hauv Central America.

SAE 1006/1008: Cov ob cov pa roj carbon qis qis yog cov khoom siv tseem ceeb rau kev tsim cov khoom sib xyaw ua ke. Royal Steel Group ib zaug xa tawm 14,000 tons ntawm SAE 1008 kub dov coils rau Brazil.

(III) Weathering Structural Steel: A588 Gr B
A588 Gr B weathering steel, nrog rau nws tus kheej-kho xeb txheej, tau txais kev ua lag luam nyob rau hauv cov av noo siab thiab corrosive ib puag ncig pom nyob rau hauv Central America.
Mexico ib zaug imported 3,000 tons ntawm A588 Gr B kub-kuav los tiag steel daim hlau los ntawm peb lub tuam txhab rau siv nyob rau hauv ntug dej hiav txwv choj thiab chaw nres nkoj infrastructure tsim.

(IV) General-Purpose Carbon Steel: SS400 thiab ASTM A36 Cov Khoom Siv Yooj Yim
SS400 (Japanese qauv) thiabASTM A36(American standard) yog "cov khoom siv tseem ceeb" rau Central American kev lag luam. Nrog cov txiaj ntsig zoo ntawm 245 MPa thiab 250 MPa, feem, lawv tsim nyog rau cov khoom siv hluav taws xob qis thiab kev tsim khoom siv dav dav. Royal Steel Group's Colombian cov neeg siv khoom feem ntau yuav 3.0mm qauv steel daim hlau ua los ntawm SS400 rau kev tiv thaiv daim ntawv thov hauv kev thauj mus los thiab kev tsim kho platform.

Royal Steel Groupmuaj "kev cai + kev xa khoom sai", pab daws cov sijhawm nruj ntawm cov haujlwm hauv Central America.

Tuam Tshoj tus kub-kuav los tiag steel phaj export nqi yog 15% -20% qis dua cov nyob sab Europe thiab lub tebchaws United States. Royal Steel Group, lub tsev hauv paus hauv Tianjin, khav theeb kev xa khoom los ntawm Tianjin Chaw nres nkoj thiab Shanghai Chaw nres nkoj, mus txog qhov chaw tseem ceeb xws li Nicaragua thiab Mexico, ntxiv txo cov nqi muag khoom tag nrho.

Peb zoo siab txais tos cov lus nug thiab kev koom tes los ntawm cov tuam txhab tsim vaj tsev, cov tuam txhab tsim khoom, thiab cov koom tes ua lag luam hauv Central America thiab thoob ntiaj teb! Txawm hais tias nws yog cov paub tab, cov qib tseem ceeb xws li Q345B thiab SPHT1, lossis cov khoom lag luam customized xws li A588 Gr B weathering steel thiab Q420B high-strength steel, Royal Steel Group muaj cov kev pabcuam ib-nres, suav nrog ib-rau-ib qho kev daws teeb meem, tus qauv pub dawb, thiab kev taug qab dej hiav txwv tag nrho, los pab koj cov dej num ua tiav kev txo nqi, kev txhim kho lub sijhawm, thiab kev txhim kho. Peb tos ntsoov yuav ua haujlwm nrog koj los tsim daim phiaj xwm tshiab rau kev lag luam thiab kev tsim kho vaj tse hauv Central America!
