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.

Signs for railway stations, airports and subways2026-02-16T12:50:00+08:00

The Functions and Classification of Public Transport Station Signage and Guidance Systems

The so-called public transportation signs, including the airport, railway station and subway sign guidance systems, have the function of identification and indication. This function has two layers of meaning: one is the actual indication meaning, which points out the location, direction, road and behavioral momentum, such as the entrance of the place, the restroom, the parking lot, etc.; the other is the psychological identification of the wayfinder, that is, the form, shape, texture and placement of the guidance system design should reflect the cultural or regional context.
According to the first meaning of the communication function, the design of the subway sign guidance system can be divided into five major types: identification, direction, space, explanation and restriction.
Identification of wayfinding system design.
The identification wayfinding system design refers to the design that indicates where one is or what something is, mainly including designs aimed at distinction. For instance, landmark buildings, murals, sculptures, restrooms, and parking lots, etc.
2. Directional signage system design.
Directional signage system design mainly refers to the design of route signs that guide to specific places and facilities through indicators such as arrows. This type of design aims to guide the direction of passage and is suitable for situations where direct guidance to the destination is needed. For example: road signs, billboards and arrows, etc.
3. Spatial wayfinding system design.
The design of spatial wayfinding systems refers to the design that visually or tactilely represents positional relationships through maps or graphics. It is based on the principle of comprehensive guidance, allowing users to grasp the overall structure and selectively utilize spatial position information to guide them to their destinations.
4. Explain the design of the wayfinding system.
Wayfinding systems are typically found in environments prone to ambiguity or designed to explain situations, serving the functions of conveying the intentions of managers and the content of facilities. To more accurately explain ambiguity or situations, such wayfinding systems are often designed in the form of articles.
5. Management of wayfinding system design.
Management wayfinding system design refers to the design aimed at indicating legal and administrative regulations. Generally, it mainly represents items that require attention, and performs the function of urging people to pay attention to safety and abide by the order.

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 is the method for making illuminated letters for building signs?2026-02-16T13:17:44+08:00

The production of illuminated building sign letters usually involves several steps, including design, material selection, manufacturing and installation. Here is a detailed process:
### 1. Design
– **Font Selection**: Choose an appropriate font based on the brand or architectural style.
– **Size Determination**: Determine the font size based on the building’s size and viewing distance.
– **Color and Effects**: Select the luminous color and decide whether dynamic effects (such as gradient or flashing) are needed.
### 2. Material Selection
– **LED Lights**: LED lights are commonly used as the light source due to their energy efficiency, long lifespan, and high brightness.
– **Shell Materials**: Stainless steel, aluminum plates, and acrylic are frequently used. Stainless steel and aluminum plates are durable, while acrylic has good light transmittance.
– **Panel Materials**: Acrylic sheets are typically used for their uniform light transmission and variety of colors.
### 3. Production


– **Production of letter casing**: Cut, weld and grind the letter casing according to the design drawings.
– **Installation of LED lights**: Evenly install LED lights inside the letter casing to ensure uniform light distribution.
– **Production of panels**: Cut acrylic sheets and fix them onto the letter casing.
### 4. Installation
– **Fixing the brackets**: Install the brackets on the building to ensure they are stable.
– **Connecting the circuit**: Connect the illuminated letters to the power supply to ensure the circuit is safe.
– **Testing**: After installation, test the illuminated effect to ensure uniform brightness.
### 5. Maintenance
– **Regular Inspection**: Regularly inspect the circuit and LED lights, and replace damaged parts in a timely manner.
– **Cleaning and Maintenance**: Regularly clean the surface to keep it looking good.
### Precautions
– **Safety**: Ensure the installation is secure and the circuit complies with safety standards.
– **Waterproof and Dustproof**: When used outdoors, make sure to take waterproof and dustproof measures.
– **Energy Conservation and Environmental Protection**: Choose energy-saving LED lights to reduce energy consumption.
By following these steps, building sign illuminated letters that meet the requirements can be produced.
