Strictly compliant with GB\/T 23858 national standards and EN124 European standards, it is precision-cast from QT500-7 high-strength ductile iron. Its large 36-inch diameter perfectly adapts to large inspection manholes, capable of withstanding extreme loads and frequent traffic flow. The cover features an internal radial reinforcement rib structure combined with a thickened design (typically \u226560 mm), evenly distributing loads to the frame and road base, effectively preventing deformation or fracture caused by stress concentration.","og_url":"https:\/\/lzbmetal.com\/vi\/nap-ho-ga-tron-gang-deo-luzhongbao-36-inch\/","og_site_name":"LZBMetal Products Co., Ltd","article_published_time":"2025-09-09T06:38:02+00:00","article_modified_time":"2025-09-09T06:38:03+00:00","author":"luzhongbao","twitter_card":"summary_large_image","twitter_creator":"@Levi_Luzhongbao","twitter_misc":{"\u0110\u01b0\u1ee3c vi\u1ebft b\u1edfi":"luzhongbao","\u01af\u1edbc t\u00ednh th\u1eddi gian \u0111\u1ecdc":"2 ph\u00fat"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"Article","@id":"https:\/\/lzbmetal.com\/luzhongbao-36-inch-ductile-iron-round-manhole-cover\/#article","isPartOf":{"@id":"https:\/\/lzbmetal.com\/luzhongbao-36-inch-ductile-iron-round-manhole-cover\/"},"author":{"name":"luzhongbao","@id":"https:\/\/lzbmetal.com\/#\/schema\/person\/03225aba1019488054ecea53728c5cf0"},"headline":"LuZhongBao 36-Inch Ductile Iron Round Manhole Cover","datePublished":"2025-09-09T06:38:02+00:00","dateModified":"2025-09-09T06:38:03+00:00","mainEntityOfPage":{"@id":"https:\/\/lzbmetal.com\/luzhongbao-36-inch-ductile-iron-round-manhole-cover\/"},"wordCount":280,"commentCount":0,"keywords":["Ductile Cast Iron","Luzhongbao","Manhole Cover"],"articleSection":["Ductile Cast Iron Products","Products","Round Manhole Cover"],"inLanguage":"vi","potentialAction":[{"@type":"CommentAction","name":"Comment","target":["https:\/\/lzbmetal.com\/luzhongbao-36-inch-ductile-iron-round-manhole-cover\/#respond"]}]},{"@type":"WebPage","@id":"https:\/\/lzbmetal.com\/luzhongbao-36-inch-ductile-iron-round-manhole-cover\/","url":"https:\/\/lzbmetal.com\/luzhongbao-36-inch-ductile-iron-round-manhole-cover\/","name":"N\u1eafp h\u1ed1 ga tr\u00f2n b\u1eb1ng gang d\u1ebbo LuZhongBao 36 inch - N\u1eafp h\u1ed1 ga tr\u00f2n b\u1eb1ng gang d\u1ebbo - C\u00f4ng ty TNHH S\u1ea3n ph\u1ea9m kim lo\u1ea1i Hubei Luzhongbao","isPartOf":{"@id":"https:\/\/lzbmetal.com\/#website"},"datePublished":"2025-09-09T06:38:02+00:00","dateModified":"2025-09-09T06:38:03+00:00","author":{"@id":"https:\/\/lzbmetal.com\/#\/schema\/person\/03225aba1019488054ecea53728c5cf0"},"description":"N\u1eafp h\u1ed1 ga tr\u00f2n b\u1eb1ng gang d\u1ebbo LuZhongBao 36 inch (\u2248914 mm) l\u00e0 s\u1ea3n ph\u1ea9m b\u1ea3o v\u1ec7 hi\u1ec7u su\u1ea5t cao, \u0111\u01b0\u1ee3c thi\u1ebft k\u1ebf cho c\u00e1c \u1ee9ng d\u1ee5ng si\u00eau ch\u1ecbu t\u1ea3i nh\u01b0 \u0111\u01b0\u1eddng giao th\u00f4ng \u0111\u00f4 th\u1ecb, b\u1ebfn c\u1ea3ng v\u00e0 \u0111\u01b0\u1eddng b\u0103ng s\u00e2n bay.
