In usually, it includes Metal and Plastic (HDPE) duct two types, which distinguish by their raw materials. The metal duct includes two types of galvanized steel and non-galvanized black steel. Each type duct includes two types of Round and Flat by the section shape. Application:  corrugated pipe is mainly used in highway, railway, municipal bridge engineering, elevated bridge, water conservancy project, large iron and steel plant construction (pre buried bolt Engineering) and large-scale high-rise building engineering pre-stressed corrugated pipe system products, grouting construction.PARAMETER OF ROUND DUCTSMODELSTRAND NO.INNER SIZEYM15-2, 32, 3 50 MMYM15-4, 54, 555 MMYM15-6, 76, 770 MMYM15-8, 98, 980 MMYM15-10, 11, 12, 13, 14, 15, 16, 1710, 11, 12, 13, 14, 15, 16, 1790 MMYM15-18, 1918, 19100 MMYM15-21, 2221, 22120 MMYM15-25, 26, 27, 30, 3125, 26, 27, 30, 31130 MMYM15-34, 3734, 37140 MMYM15-43, 44, 54, 5543, 44, 54, 55160 MM  Metal / Plastic Round Corrugated Duct ParameterUse for Multi-hole AnchorageInner DiameterOuter DiameterModels Φ55Φ60 / Φ66YJM15-3~5Φ70Φ75 / Φ81YJM15-6~7Φ80Φ85 / Φ91YJM15-8~9Φ90Φ95 / Φ101YJM15-10~17Φ100Φ105 / Φ114YJM15-18~19Φ120Φ125 / Φ134YJM15-21~23  PARAMETER OF FLAT DUCTSMODELBM13/15-2BM13/15-3BM13/15-4BM13/15-5INNER SIZE50 X (22-25) MM60 X (22-25) MM74 X (22-25) MM90 X (22-25) MM/* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
