Kev Tswj Xyuas Zoo ntawm Wrought Iron Fences:
1. Ua ntej txhua qhov kev teeb tsa, lub formwork yuav tsum tau ntxuav thiab coated nrog ib tug tso tawm tus neeg sawv cev, uas yuav tsum tau thov tusyees.
2. Kev sib txuas thiab kev sib txuas ntawm lub laj kab kev txhawb nqa yuav tsum ua kom tau raws li cov qauv tsim thiab cov kev xav tau tshwj xeeb, tshwj xeeb tshaj yog qhov tseeb qhov chaw ntawm lub qhov rooj rau sab hauv.
3. Tom qab kev teeb tsa formwork, xyuas cov sab thiab sab saum toj ntawm lub formwork; ob sab thiab saum npoo yuav tsum ncaj.
4. Honeycomb thiab pitted nto thaj tsam ntawm lub laj kab ua vaj tse yuav tsum tsis txhob ntau tshaj 0.5% ntawm qhov chaw, thiab qhov tob yuav tsum tsis txhob ntau tshaj 10mm.
5. Lub laj kab ntawm ib sab nyob rau hauv tib lub sijhawm yuav tsum tau nchuav rau hauv ib qho mus. Steel formwork yuav tsum tau siv nyob rau hauv qhov kawg kom paub tseeb tias ib tug flush tsos.
6. Yuav tsum tsis muaj qhov tawg ntawm lub laj kab thiab ntawm cov pob qij txha. Cov teeb meem tsis zoo, flatness, thiab cov teeb meem zoo li yuav tsum tau hais kom sai, thiab cov xim sib xws yuav tsum tau ua kom ntseeg tau. Sab saum toj nto yog du thiab aesthetically pleasing, nrog rau qhov siab sib xws.
7. Cov guardrails ncaj nraim rau tag nrho tus choj txoj kab kab, thiab cov ntu nkhaus yog sib npaug thiab du, tsis muaj kab tawg lossis cov kaum sab xis tuag.
