A500 ERW Cov Qauv Hlau Yeeb Nkab piav qhia
A500 structural tubing yog ib hom txias- ua hlau nrog square cross-section, feem ntau yog ua los ntawm carbon structural steel los yog qis- alloy structural steel. A500 qhia tau hais tias cov hlau tus qauv yield zog yog 500 MPa, qhia tau hais tias muaj zog thiab toughness. Hom square tubing no tuaj yeem tiv taus cov khoom loj hauv kev ntxhov siab thiab muaj qhov zoo weldability thiab txias -bending kev ua tau zoo. Vim nws txias- txheej txheem tsim, nws muaj qhov sib npaug ntawm qhov chaw thiab qhov siab qhov tseeb, ua rau nws tsim nyog rau cov ntawv thov uas xav tau siab precision hauv cov khoom.
Daim ntawv thov teb:
Kev tsim kho: High-nce tsev kab, stairwell frameworks, stadium space frame structures.
Mechanical Engineering:Crane booms, conveyor khiav tshuab, ua liaj ua teb machinery chassis.
Infrastructure:Choj guardrail kev txhawb nqa, txoj kev teeb ncej ncej, subway platform bracings.
Kev tsim tsheb:Trailer skeletons, cargo thawv thav duab rau logistics.
