Origin: China

Introduction to bridge cast iron guardrail brackets：
Bridge cast iron guardrail brackets are an important part of the bridge safety protection system. They are usually installed on both sides of the bridge deck to fix metal or concrete guardrails to ensure the safety of pedestrians and vehicles. Its common model body is made of cast iron, with high strength and durability, suitable for all types of highways and municipal bridges.

Conventional size:
The size of the bracket is flexibly adjusted according to the design requirements of the bridge. The common parameter range is as follows:
Height: 300mm (suitable for some bridges that can meet basic protection needs)
350mm (commonly used in bridges with large traffic volume)
450mm (for bridges with special requirements for special design protection height)
Inner diameter of the hole: 80mm (matching the outer diameter of the steel pipe)
83mm (adapting to steel pipes of different outer diameters)

pplication suggestions:

cast iron guardrail brackets are suitable for key bridge projects with long-term safety and landscape unity. In saline-alkali areas or coastal environments, it is recommended to use ductile iron and strengthen anti-corrosion treatment to balance the cost and durability requirements. For lightweight or frequently dismantled temporary bridges, alternative materials (such as galvanized steel) can be considered.

Embedded parts:
Embedded steel plate: The common size is 130*170mm, and the thickness is generally 2mm or determined according to the design requirements.
Embedded bolts: total length 250mm, diameter 16mm, spacing between holes 70*70mm

Advantages:
1. Stable structure: cast iron has strong compressive resistance and can effectively bear the guardrail load, which is lower than the impact of vehicle collision.
2. High durability: corrosion-resistant and anti-oxidation, adapting to outdoor temperature differences, rain and other weather conditions, the service life can reach more than 30 years.
3. Simple maintenance: basically maintenance-free after surface anti-rust treatment (galvanizing, spraying), low long-term use cost.
