CLASSIFICATION OF ARTISTIC MANHOLE COVERS

Artistic manhole covers usually come in two forms.

The first type is the colored manhole cover.

The second type is the copper-faced manhole cover.

1、COLORFUL ARTISTIC MANHOLE COVERS

Colored manhole covers are usually made by applying outdoor wear-resistant resin, fluorocarbon and other materials on the surface of cast iron manhole covers or the combination type (iron and aluminum relief, aluminum base with aluminum relief), forming richly colored patterns on the surface. Generally, Japanese manhole covers are mostly made by filling resin on cast iron. If the custom quantity is small or the pattern is required to be fine, the aluminum combination type artistic manhole cover of Master Jingshang can be adopted.

2、COPPER-EFFECT FINISH MANHOLE COVER

可以做成青铜、黄铜、红铜的效果,有4种方法,可以做成的铜表面井盖

1.Casting bronze or red copper requires a large amount of copper, which makes it relatively expensive, but it is suitable for long-term use.

2. Cast iron is used as the load-bearing base, and an 8-millimeter-thick embossed copper plate is placed in the surface grooves. The two materials are physically combined to form a complete finished manhole cover. This method is suitable for small batches and can be used for a long time.

3. Patterns and characters are cast in cast iron and then covered with a 0.5 – 1mm thick layer of bronze, brass or red copper by laser to reduce production costs. It can be used for 6 – 8 years without wearing out. Even if it does wear out, it still looks good and is suitable for long-term use.

4. Patterns and characters are cast in cast iron and then electroplated with 0.1-millimeter-thick bronze, brass or red copper to reduce production costs. It can be used for one year before wearing out, but it is very cheap and not suitable for long-term use.

What are the classifications of artistic manhole covers?2026-02-16T13:04:28+08:00

There are generally two forms of artistic manhole covers.
The first type is the colored manhole cover.
The second type is the copper-faced manhole cover.

Let’s start with the first type, the colored manhole cover. Colored manhole covers are usually made by applying outdoor wear-resistant resin, fluorocarbon and other materials on the surface of cast iron manhole covers. Generally, the way manhole covers are made in Japan falls into this category.

Let’s talk about the second type, the copper-faced manhole cover.
There are four methods to make copper surface manhole covers with the effects of bronze, brass or red copper.
1. Casting bronze or red copper requires a large amount of copper and is relatively expensive, but it is suitable for long-term use.
2. Using cast iron as the load-bearing base and placing an 8-millimeter thick embossed copper plate in the surface grooves, the two materials are physically combined to form a complete finished manhole cover. This method is suitable for small batches and can be used for a long time.
3. Casting patterns and characters with cast iron and covering the surface with a 0.5 – 1-millimeter thick layer of bronze, brass or red copper by laser. This can reduce production costs. It can be used for 6-8 years without wearing out, and even if it wears out, it still looks good, making it suitable for long-term use.
4. Casting patterns and characters with cast iron and electroplating a 0.1-millimeter thick layer of bronze, brass or red copper on the surface to reduce production costs. It can be used for one year before wearing out, but it is very cheap and not suitable for long-term use.

What are the industry principles and charging standards for custom-made sign products?2026-02-16T13:22:57+08:00

The industry principles and charging standards for custom sign products vary depending on factors such as application scenarios, materials, processes, and design complexity. The following is an overview of the general principles and charging standards in the custom sign industry:

### Industry Principles
1. **Customer Needs First**
– Customized sign production prioritizes meeting customer needs, including functionality, aesthetics, and brand consistency.
– Designers must communicate thoroughly with customers to ensure that the design solutions meet their expectations.
2. **Quality Assurance**

### **Charging Model**
1. **Project-based Pricing**
– This is suitable for large or complex custom sign projects. Designers and manufacturers will provide an overall quote based on project requirements.
2. **Charging by Area**
– Applicable to flat signs, such as billboards and wall signs, etc., the cost is usually calculated per square meter.
3. **Per-piece Pricing**
– Applicable to small signs or batch production, such as doorplates, direction signs, etc.
4. **Design Fee + Production Fee**
– The design fee and production fee are calculated separately. The design fee is usually charged by the hour or per project, while the production fee is calculated based on materials and craftsmanship.
5. **Additional Service Fees**
– These include installation fees, transportation fees, maintenance fees, etc., and are usually quoted separately based on actual needs.

### **Examples of Price Ranges**
The following are the approximate price ranges for some common custom signboards (for reference only; actual prices may vary by region and supplier):
1. **Simple Door Signs**: 50 – 200 yuan per piece (Materials: Acrylic, Metal).
2. **Outdoor Advertising Boards**: 500 – 2000 yuan per square meter (Materials: Printed fabric, LED).
3. **Electronic Signboards**: 1000 – 5000 yuan per square meter (Material: LED display).
4. **High-End Custom Signboards**: Over 5000 yuan (Materials: Stainless steel, Copper; Processes: Engraving, Electroplating).

### **Summary**
The charging standards and principles in the custom sign industry vary depending on project requirements. When choosing a supplier, customers should comprehensively consider factors such as design, materials, craftsmanship, and installation. At the same time, selecting an experienced supplier can ensure the quality and compliance of the signs and prevent potential issues in the future.
