Steel Structure Light Industrial Unit

Shenyang Zishenlong Lub teeb Steel Xim Phaj Co., Ltd. Txais tos kom yuav CE thiab ISO pom zoo steel qauv teeb muaj chav tsev ntawm tus nqi qis los ntawm peb lub hoobkas.

Lub teeb industrial units yog cov neeg ua haujlwm ntawm kev lag luam thoob ntiaj teb. Cov khw kho tsheb. Me me fabrication Rhiav. Local faib depots. Contractor yards. Agricultural processing sheds. Furniture manufacturing. Txias cia. Txhua lub lag luam no khiav tawm ntawm lub tsev uas tej zaum tau pib ua "ib ntus" kev daws teeb meem thiab xaus li 20 xyoo hauv tsev.

Qhov teeb meem yog tias feem ntau cov tsev lag luam teeb pom kev zoo yog tsim tsis raug. Tsis txaus ntshai tsis ncaj ncees lawm - tsuas yog kim tsis raug. Tus neeg tsim khoom hais txog cib thiab mortar, lub sijhawm ncua mus txog rau lub hlis, cov peev nyiaj tau tawg los ntawm 30%, thiab lub ru tsev pib tawm hauv xyoo peb. Lub caij no, cov hlau lwm yam - sai dua, muaj zog dua, pheej yig dua lub neej voj voog - tau raug tso tseg raws li "kev lag luam dhau lawm" lossis "tshaj dhau."

Qhov ntawd yog qhov sib txawv ZSL sau. Cov qauv steel lub teeb muaj chav tsev los ntawm peb yog engineered, fabricated, shipped, thiab tsim nyob rau tib lub sij hawm uas ib txwm builder siv rau footings. Thiab vim tias txhua yam khoom yog ua ntej- txiav, ua ntej-drilled, thiab ua ntej- tiav hauv peb lub Hoobkas ISO 9001, cov hlau mus ua ke nrog qhov tseeb ntawm lub tiaj tus- pob rooj tog - ntawm qhov ntsuas ntawm lub tsev lag luam.

Koj xav tau dab tsi loj?

Lub teeb muaj steel vaj tse npog ntau yam, tab sis qhov chaw qab zib rau cov tswv feem ntau - cov neeg ua haujlwm nyob nruab nrab ntawm 200 thiab 1,500 square meter. Hauv qab 200 sqm, koj nyob hauv thaj tsam ntawm kev cob qhia me me thiab chaw cia khoom - tseem siv tau zoo hauv cov hlau, tab sis tus nqi ib -square- meter tus nqi pheej yig dua me ntsis vim tias cov ncej tonnage tsis scale down linearly. Tshaj li 1,500 sqm, koj tab tom nkag mus rau thaj chaw faib khoom, qhov chaw nres nkoj thiab siab -bay racking pib ua tus tsim luv luv.

Ib qho kev txiav txim siab tseem ceeb tshaj plaws yog eave qhov siab. Rau cov qauv teeb pom kev lag luam - pib rhiav, lub Hoobkas me, cia - 4.5 txog 6 meters npog feem ntau siv. Yog tias koj tab tom txhim kho lub tsheb hoist, mus rau qhov tsawg kawg nkaus 5.5 meters. Yog tias koj tab tom khiav lub tsheb thauj mus los hauv pallet racking, 6 meters cia koj pawg plaub qib pallet nrog kev yooj yim tshem tawm. Txhua qhov 'meter' ntxiv ntawm eaves qhov siab ntxiv kwv yees li 3-5% rau tus nqi steel thav duab - muaj txiaj ntsig, tab sis pheej yig dua li pom koj lub forklift tsis haum hauv qab lub rafter tom qab lub tsev nce.

Span yog qhov hloov pauv tseem ceeb thib ob. ZSL lub teeb muaj kev lag luam siv cov ntshiab -span portal thav duab - tsis muaj kab sab hauv, tsis muaj kev cuam tshuam.
