1. High Strength: Magnesium oxide manhole covers possess high resistance to compression, bending, and impact, and are also tough. Even after long-term use, the covers will not be crushed or damaged, effectively preventing "urban black hole" accidents.
2. Beautiful Appearance: Magnesium oxide manhole covers feature exquisite surface patterns and bright, adjustable colors, beautifying the urban environment.
3. Convenient Use and Lightweight: Weighing only about one-third that of cast iron, these covers facilitate transportation, installation, and emergency repairs, significantly reducing labor intensity.
4. Anti-theft: Magnesium oxide manhole covers have no recycling value, naturally preventing theft; locking mechanisms can be added according to customer needs to prevent theft of valuables inside the manhole.
5. Strong Weather Resistance: Through scientific formulation, advanced technology, and sophisticated equipment, magnesium oxide manhole covers can be used normally in environments ranging from -50℃ to +300℃.
6. Resistant to acids and alkalis, corrosion, wear, and vehicle pressure, with a long service life.
