There are several ways to create copper effect artistic manhole covers.
1. Copper casting: Directly use copper for casting processing to make the manhole cover. This method can obtain the purest copper texture, but the cost is high.
2. Copper layer covering: Cover a copper layer on the surface of the manhole cover through electroplating, hot dip galvanizing or other surface treatment technologies to achieve a copper effect.
3. Copper paint spraying: Spray oil paint with copper color and texture effect on the surface of the manhole cover.
4. Copper skin wrapping: Wrap copper skin on the outer surface of the manhole cover.
5. Imitation copper materials: Use new composite materials with similar appearance and properties of copper to manufacture the manhole cover. Different manufacturing methods will have differences in cost, appearance effects, and durability, and suitable methods can be chosen according to specific needs and budget.
6. If considering cost-effectiveness and service life, we recommend SHENGYILONG's patented product, which is the laser cladding copper technology on cast iron surface. This method has a moderate price and a relatively long service life.
