Rail padyog ib qho tseem ceeb elastic tivthaiv nruab ntawm cov tsheb ciav hlau thiab pw hauv txoj kev tsheb nqaj hlau taug kev. Nws lub luag haujlwm tseem ceeb yog kom nqus cov kev cuam tshuam, txo cov kev cai vibration, tiv thaiv cov zes pw tsaug zog, thiab tswj kev coj ua kom muaj kev ruaj khov.
Nyob ntawm cov xwm txheej khiav, qib ceev, thiab ib puag ncig cov ntaub ntawv, cov ciav hlau ib puag ncig, hluav taws xob tsheb ciav hlau pad, thiab HDPE tsheb ciav hlau ncoo.

Lub HDPE railroad ncoo (siab - ntom polyethylene ntaub), tus cwj pwm los ntawm cov siab ntawm lub zog tsis kam, thiab tshuaj lom neeg tsis kam. Nws yog mas thov tau hnyav - haul railways loj, zoo tiv thaiv cov xuab zeb abarste thiab deformation nyob rau hauv kev kub siab. Nws cov dej nqus dej qis thiab UV tsis kam ua rau nws haum rau kev tsheb ciav hlau hauv siab {4 {{{} um plast ib puag ncig.

Eva Railway Pad (Ethylene Vinyl acetate Copolymer ncoo) yog lub teeb yuag, tawv, thiab muaj kev nyuaj siab, thiab tiv taus kev laus. Nws yog feem ntau siv nyob rau hauv nruab nrab- thiab qis {- Kev kub ceev thoob plaws thaum muaj cov dej ntws tawm ntawm qhov ntau thiab {{}} tiv taus cov khoom. Nrog tus nqi qis dua, nws yog qhov zoo tagnrho rau kev tsheb ciav hlau nrog kev co kev co kom txo tau.
Gnee RailMuab customized kev tsheb ciav hlau rau cov kev mob tsheb ciav hlau sib txawv, muab peb cov khoom lag luam sib txawv Peb kuj tseem muab cov clips me ntsis, ntsuas cua blocks, ntses daim hlau, thiab bolted rolled rastening tshuab raws li cov khoom siv txhawb nqa. Tsis tas li ntawd, GNEE Rail muaj kev xaiv cov teeb tsa, cov ntaub ntawv kev xaiv, thiab kho cov kev pabcuam kev tsheb nqaj hlau ua haujlwm, ruaj khov, thiab cov xwm txheej ib puag ncig.
