Kev piav qhia
Lub tswv yim ntawm welded steel fabric / mesh yog thawj zaug npaj rau xyoo 1901, thaum thawj daim ntawv thov loj yog xyoo 1908. Hauv xyoo 1922, nws tau raug sim los ua cov khoom tsim nyog rau txoj kev tsheb loj. Thaum kawg ntawm Ntiaj Teb Tsov Rog II, nws tau pom nws lub zog vim tias nws yuav tsum tau ua haujlwm tsawg thiab sijhawm. Nws tau pom tias yog cov khoom siv txhawb zog zoo tshaj plaws los pab Tebchaws Europe rov tsim dua tom qab tsov rog. Ua ntej lub lem ntawm lub xyoo pua, nws tau txais raws li ib tug siv tau daim ntawv ntawm pob zeb reinforcement nyob rau hauv lub tsev. Nws kuj tau txais txiaj ntsig zoo hauv lwm cov haujlwm xws li tshav dav hlau khiav thiab ntau lub tsev tsim vaj tsev.

Qhov zoo
Txhim kho kev tawg tsis kam
Kev tsim cov welded steel mesh yog npaj txhij thiab kuaj xyuas. Cov ncauj lus kom ntxaws tsim tshwj xeeb nteg tawm qhov raug xaim sib nrug, uas ua rau cov khoom thauj sib npaug sib npaug thoob plaws tag nrho cov qauv pob zeb. Yog li ntawd, txo cov kab nrib pleb tshwm sim. Qhov tseeb, cov txiaj ntsig tau ua tiav hauv Tebchaws Meskas qhia tau hais tias txoj kev pavement nrog steel mesh tuaj yeem txo ntau dua 75% qhov tshwm sim ntawm qhov sib piv rau cov tsis muaj.
Ua kom cov khoom tsim tau
Nrog welded steel mesh, lub sij hawm siv rau ntawm qhov chaw ncaj nraim, txiav, khoov thiab kho tuaj yeem txo mus txog 70% tus txiv neej-teev, uas ua rau lub sijhawm tsim kho.
Kev lag luam tiam sis thiab kev cia siab
Cold-rolled ribbed steel hlau thiab welded steel mesh, uas kuj yog cov khoom siv hauv tsev tshiab thiab muaj txiaj ntsig tau teev tseg raws li Ministry of Construction "Ninth Five" program, tsom rau kev txhawb nqa kev siv cov ntaub ntawv tsim kho tshiab thiab thev naus laus zis. Nws yog khi rau siv dav hauv kev tsim kho, txhawm rau txhim kho qib kev lag luam ntawm cov rebar ua haujlwm, ua rau muaj kev lag luam ntau dua thiab cov txiaj ntsig kev sib raug zoo.
