ASTM A500 / A500M Gr.C square tube piav qhia
ASTM A500 / A500M Txuj: Cov qauv no, luam tawm los ntawm ASTM International, qhia txog qhov yuav tsum tau ua rau txias - ua welded thiab seamless carbon steel structural tubing nyob rau hauv round, square, thiab rectangular duab. Nws qhia txog cov khoom siv kho tshuab, tshuaj lom neeg muaj pes tsawg leeg, kev tsim khoom, thiab lwm yam kev cuam tshuam rau cov raj no.
Qib C (Gr.C): Qhov no yog hais txog qib tshwj xeeb hauv ASTM A500 tus qauv, uas muaj cov kev xav tau siab dua rau lub zog tensile thiab lub zog tawm los piv rau Qib A thiab B, ua rau nws tsim nyog rau kev thov cov qauv siv ntau dua.
Square lossis Rectangular Cross -Sections: Cov hlab yog tsim rau hauv cov duab plaub los yog duab plaub los ntawm kev ua kom txias - txoj kev ua haujlwm, uas cuam tshuam nrog kev khoov tiaj tiaj steel strips lossis coils ntawm chav tsev kub kom ua tau raws li tus ntoo khaub lig xav tau -sectional shape.

Daim ntawv thov
ASTM A500 / A500M Gr.C square raj yog dav siv nyob rau hauv ntau yam kev siv vim nws cov khoom zoo heev. Qee qhov kev siv feem ntau suav nrog:
Kev tsim vaj tsev: Siv los ua cov txheej txheem tseem ceeb hauv cov tsev, xws li kab, kab teeb, thiab trusses, los txhawb nqa hnyav thiab muab kev ruaj ntseg.
Txuas hniav thiab Infrastructure: Ua hauj lwm hauv cov choj, hla hla, thiab lwm yam kev tsim kho vaj tse raws li cov tswv cuab tsim kom muaj kev thauj mus los thiab tiv thaiv ib puag ncig kev ntxhov siab.
Cov qauv tsim muaj: Siv rau hauv kev tsim kho vaj tse, xws li factories, warehouses, thiab fais fab nroj tsuag, uas muaj zog thiab durability yog qhov tseem ceeb.
Offshore thiab Marine Applications: Haum rau siv nyob rau hauv offshore platforms, piers, thiab docks vim lawv zoo corrosion kuj thiab lub zog nyob rau hauv marine ib puag ncig.
