Nco tseg:
Qhov tsawg kawg nkaus elongation yuav tsum tau sib txawv nrog thickness:
- 0.5 hli
: Qhov tsawg kawg nkaus elongation yog txo los ntawm2%piv rau tus nqi teev tseg. - 0.35 hli
: Qhov tsawg kawg nkaus elongation yog txo los ntawm4%piv rau tus nqi teev tseg. - t Tsawg dua lossis sib npaug li 0.35 mm: Qhov tsawg kawg nkaus elongation yog txo los ntawm7%piv rau tus nqi teev tseg.
Lub zog tensile ntau rau qib no tuaj yeem sib txawv mus txog140 MPa, nyob ntawm kev ua haujlwm thiab txheej txheej specifications.
Daim ntawv thov
Vim nws lub zog siab thiab txhim khu kev tiv thaiv corrosion, S320GD muaj ntau yam kev siv hauv kev tsim kho kev lag luam:
Ru tsev thiab façade systems:trapezoidal thiab sawv seam profiles rau kev lag luam hauv tsev, cov tsev lag luam thiab cov rooj sib txoos.
Load-cov kabmob steel qauv:Ncej, kab thiab kab teeb nyob rau hauv kev tsim kho, carports thiab lub teeb yuag halls.
Cov kua dej system:gutters thiab downpipes uas ua tiav lawv txoj haujlwm nyob rau lub sijhawm ntev, txawm tias raug huab cua hnyav heev.
Hnub ci mounting systems:Substructures rau photovoltaic thiab hnub ci thermal tshuab uas yuav tsum tau muaj zog thiab tsis tshua muaj txij nkawm.
Sandwich thiab composite panels:phab ntsa thiab qab nthab cov ntsiab lus nrog cov tub ntxhais hlau rau siab rigidity thiab durability.
Lub peev xwm los hloov cov zinc txheej meej meej rau cov ntawv thov kev nyab xeeb txo cov voj voog txij nkawm thiab txo qis lub neej voj voog cov nqi ntawm cov tsev.
