FAQ:
Dab tsi ua haujlwm hnyav welded steel grating txhawb nqa?
Load muaj peev xwm nyob ntawm bearing bar loj, ncua, thiab sib nrug. Raws li kev siv, 2-1/2 "× 3/8" bearing bar ntawm 3' ncua kev txhawb nqa kwv yees li 28,800 psf (138 kN / m²) tsis tu ncua load. Cov tsheb thauj khoom yog tsim los ntawm AASHTO H-15 txog H-25. Muab koj qhov ncua sij hawm, qhov xav tau ntawm kev thauj khoom, thiab qhov yuav tsum tau muaj kev nyab xeeb - peb pab neeg ua haujlwm engineering yuav suav cov lus qhia meej rau koj qhov project.
Welded vs xovxwm- xauv - uas muaj zog dua rau kuv daim ntawv thov?
Welded grating muaj zog heev nyob rau hauv dov loads, cuam tshuam, thiab kev co vim nws metallurgical fusion sib koom. Xovxwm- xauv yog tsim nyog rau lub teeb rau cov neeg taug kev thiab raug nqi 10–20% tsawg dua. Txoj cai ntawm tus ntiv tes xoo: yog forklifts, tsheb thauj khoom, lossis cov tshuab hnyav yuav dov nws - xaiv welded. Yog hais tias nws yog cov zoo nkauj ntshiab los yog lub teeb ko taw tsheb - nias- xauv tuaj yeem txaus.
Koj puas tuaj yeem kho qhov loj me, qhov sib nrug, thiab tsim rau peb cov duab kos?
Yog lawm. Peb lees txais PDF / DWG / DXF cov duab kos thiab tsim cov vaj huam sib luag zoo tag nrho nrog rau tsis yog - qhov loj me, qhov sib txawv tshwj xeeb, txiav tawm rau cov kav dej / khoom siv, qhov kawg banding, ntiv taw daim hlau, stair tread nosing, thiab cov duab tsis zoo. Peb pab pawg engineering tshuaj xyuas txhua daim duab rau kev tsim khoom ua ntej tsim khoom.
Ntev npaum li cas galvanized steel grating nyob sab nraum zoov?
Kub-dip galvanized rau ASTM A123 nrog 70-100 µm zinc txheej xa 40–50+ xyoo ntawm kev pab cuam lub neej nyob rau hauv ib txwm atmospheric tej yam kev mob. Nyob rau hauv ntug dej hiav txwv los yog muaj huab cua (C4-C5 ib ISO 9223), cia siab tias 25-35 xyoo. Rau ib puag ncig hnyav, hloov mus rau stainless hlau 316 lossis siv epoxy topcoat ntxiv.
