Signpost Base is one of the important and essential components in installation and establishment of various types of urban, advertising, administrative and industrial signs.
This structure acts as a supporting column and its duty is to hold the sign at an appropriate height and in a safe position.
Signpost Bases are usually made of strong steel or hot-dip galvanized steel so that they do not suffer wear or rust against environmental conditions such as wind, rain, sunlight and humidity.
Main components of a Signpost Base
Each Signpost Base consists of several important parts, each of which has a specific role in the stability of the structure:
Pipe or main column: The vertical part on which the sign is installed.
Base plate: For connecting the Signpost Base to the foundation.
Anchor bolts: For fixing the Signpost Base to the ground.
Arm or holding clamp: For holding the sign at a specific angle and position.
Anti-rust coating: To prevent metal corrosion.
Types of Signpost Bases according to shape and application
Signpost Bases are made in various models, which are selected according to installation location, type of sign, and wind conditions of the area.
Tubular Signpost Base
Tubular Signpost Bases are among the most widely used types.
This model is made of steel pipe and is very suitable for traffic and guidance signs.
Reasonable price, easy installation, and high resistance are the characteristics of this type.Polygonal Signpost Base
These Signpost Bases are made from bent steel sheets and have a polygonal cross-section.
Due to their special design, they have high resistance against wind and are usually used for advertising or highway signs.Lattice Signpost Base
These types of Signpost Bases are made from lattice steel sections, have low weight, and are easy to install.
Because of their adjustable structure, they are widely used in temporary or workshop projects.Arm-type Signpost Base
In this model, an arm extends from the main body and the sign is installed on it.
For routes with two-way visibility, this Signpost Base is the best option.
Material and coating of Signpost Bases
Signpost Bases are usually made from ST37 or ST52 steel, which have high mechanical strength.
After manufacturing, their surface is coated by one of the following methods to increase durability:
Hot-dip galvanizing: The best method to prevent rust in open spaces.
Electrostatic powder coating: Suitable for urban and advertising environments.
Industrial epoxy paint: Resistant against impact and chemicals.
Height and dimensions of Signpost Bases
The height of Signpost Bases is determined based on the type of sign and installation position.
On average:
Urban signs: 3 to 5 meters
Highway signs: 6 to 9 meters
Advertising signs: more than 9 meters
The design and calculation of these Signpost Bases must be done according to wind speed, sign weight, and urban standards.
Steps of installing a Signpost Base
Determining the installation location considering the view angle of drivers or pedestrians.
Preparing a concrete foundation with appropriate depth.
Installing the base plate and anchor bolts.
Placing the Signpost Base on the foundation and leveling it.
Connecting the sign to the Signpost Base with standard clamps.
Finally, to increase lifespan, the connection points should be covered with anti-rust paint.
Advantages of using standard Signpost Bases
Increases sign lifespan
High resistance against wind and humidity
Fast and easy installation
Neat and beautiful appearance in urban spaces
Easy maintenance and repair
Important tips when buying a Signpost Base
When buying a suitable Signpost Base, pay attention to the following:
Material type and thickness
Anti-corrosion coating (galvanized or epoxy paint)
Compatibility with sign type and installation environment
Standard dimensions and welding quality
Manufacturer or seller credibility
Conclusion
The Signpost Base is the main pillar for stability and durability of every sign.
Choosing the right type of Signpost Base, using high-quality materials, and proper installation have a direct effect on the safety and longevity of urban and advertising signs.
If you intend to buy a Signpost Base, make sure to choose from reliable and standard manufacturers, so you can be confident in the quality and stability of your structure for years without replacement.
Frequently Asked Questions about Signpost Bases (FAQ)
1. What is the best material for a Signpost Base?
The best option is hot-dip galvanized steel, because it has high durability against moisture and environmental conditions.
2. Can Signpost Bases be customized?
Yes, depending on the project need, height, diameter, color, and type of connection can be customized.
3. What is the difference between tubular and polygonal Signpost Bases?
The tubular Signpost Base is simpler and cheaper, but the polygonal type has higher wind resistance and is more suitable for larger signs.
4. Does the color of the Signpost Base affect its lifespan?
Yes, using high-quality industrial paints such as electrostatic powder or epoxy can prevent rust and corrosion.
5. What factors affect the cost of a Signpost Base?
The price depends on factors such as height, material type, pipe thickness, coating method, and installation location.
