Cast Iron Fixed Security Bollards Key Specifications

1. Material Properties

Driveway bollards are typically made of ductile iron.Compared with ordinary cast iron, it has much better toughness-when subjected to impact, it is less likely to break or shatter suddenly, thus providing reliable safety protection for the site.

2. Surface Treatment

To enhance corrosion resistance and aesthetics, cast iron fixed security bollards usually undergo specialized surface treatment. Common methods include applying multiple layers of paint (such as zinc-rich primer, undercoat, and topcoat); some products also use electrostatic powder coating. These processes form a continuous, pinhole-free coating on the bollard surface, which can withstand wind, rain, and other harsh weather conditions, prevent rusting, and ensure a long service life.

3. Design & Aesthetics

Cast iron has excellent fluidity in its molten state and superior castability, allowing it to be molded into various shapes via dies. Some bollards feature embossed decorative patterns on their bodies-these designs not only serve practical functions but also integrate seamlessly with the surrounding architectural style and landscape. For example, in European-style blocks, carved cast iron fixed bollards can add an elegant touch to the environment.

4. Installation & Fixing Methods

They are generally fixed to the ground in two ways: either by connecting the bollard to the ground using expansion bolts or by directly embedding the bollard base into a concrete foundation. Both methods ensure the bollard is firmly anchored to the ground, preventing easy displacement or tilting, and enabling long-term static safety protection for the area.
