Unlike common products where a 40mm thickness typically corresponds only to B125 (12.5t) or C250 (25t) ratings, LZBMetal achieves higher load capacity at the same thickness through material enhancement and structural optimization, covering application scenarios from B125 to C250 and beyond, offering users greater selection flexibility. Whether for routine inspection of municipal drainage, power cables, or communication fiber optics, this product reliably fulfills its safety mission with its lightweight yet robust design.","og_url":"https:\/\/lzbmetal.com\/vi\/nap-cong-vuong-bang-gang-deo-lzbmetal-kich-thuoc-400x600x40mm-trong-luong-165kg\/","og_site_name":"LZBMetal Products Co., Ltd","article_published_time":"2026-04-22T10:35:00+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":"4 ph\u00fat"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"Article","@id":"https:\/\/lzbmetal.com\/lzbmetal-ductile-iron-square-manhole-cover-400x600x40-16-5kg\/#article","isPartOf":{"@id":"https:\/\/lzbmetal.com\/lzbmetal-ductile-iron-square-manhole-cover-400x600x40-16-5kg\/"},"author":{"name":"luzhongbao","@id":"https:\/\/lzbmetal.com\/#\/schema\/person\/03225aba1019488054ecea53728c5cf0"},"headline":"LZBMetal Ductile Iron Square Manhole Cover 400\u00d7600\u00d740, 16.5kg","datePublished":"2026-04-22T10:35:00+00:00","mainEntityOfPage":{"@id":"https:\/\/lzbmetal.com\/lzbmetal-ductile-iron-square-manhole-cover-400x600x40-16-5kg\/"},"wordCount":736,"commentCount":0,"keywords":["Ductile Cast Iron","LZBMetal","Manhole Cover"],"articleSection":["Ductile Cast Iron Products","Products","Square Manhole Cover"],"inLanguage":"vi","potentialAction":[{"@type":"CommentAction","name":"Comment","target":["https:\/\/lzbmetal.com\/lzbmetal-ductile-iron-square-manhole-cover-400x600x40-16-5kg\/#respond"]}]},{"@type":"WebPage","@id":"https:\/\/lzbmetal.com\/lzbmetal-ductile-iron-square-manhole-cover-400x600x40-16-5kg\/","url":"https:\/\/lzbmetal.com\/lzbmetal-ductile-iron-square-manhole-cover-400x600x40-16-5kg\/","name":"N\u1eafp c\u1ed1ng vu\u00f4ng b\u1eb1ng gang d\u1ebbo LZBMetal, k\u00edch th\u01b0\u1edbc 400\u00d7600\u00d740mm, tr\u1ecdng l\u01b0\u1ee3ng 16,5kg - S\u1ea3n ph\u1ea9m c\u1ee7a C\u00f4ng ty TNHH S\u1ea3n ph\u1ea9m LZBMetal","isPartOf":{"@id":"https:\/\/lzbmetal.com\/#website"},"datePublished":"2026-04-22T10:35:00+00:00","author":{"@id":"https:\/\/lzbmetal.com\/#\/schema\/person\/03225aba1019488054ecea53728c5cf0"},"description":"T\u1ea5m ph\u1ee7 vu\u00f4ng LZBMetal 400\u00d7600\u00d740 v\u1edbi tr\u1ecdng l\u01b0\u1ee3ng 16,5kg \u0111\u01b0\u1ee3c thi\u1ebft k\u1ebf nh\u1eb1m \u0111\u00e1p \u1ee9ng ch\u00ednh x\u00e1c nhu c\u1ea7u ti\u1ec7n l\u1ee3i trong b\u1ea3o tr\u00ec t\u1ea1i c\u00e1c khu v\u1ef1c t\u1ea3i tr\u1ecdng nh\u1eb9 nh\u01b0 v\u1ec9a h\u00e8 v\u00e0 \u0111\u01b0\u1eddng v\u00e0o khu d\u00e2n c\u01b0.
