Glass Lined Manhole Covers 500

Product Description

Glass lined manhole covers are manhole covers that are made with a layer of glass lining on the underside of the cover. The glass lining is typically applied through a process called fusion bonding, which involves heating the glass to a high temperature and then fusing it to the metal surface of the cover.The primary purpose of glass lining on manhole covers is to increase their durability and resistance to corrosion. The glass lining creates a barrier that protects the metal surface of the cover from exposure to moisture and other corrosive elements, which can cause the cover to rust and deteriorate over time.
