[Column] What is a bridge girder? Explanation of types, structures, and which part of the bridge it is.
Introducing what bridge girders refer to with illustrations! Explanation of the types and structures of bridge girders.
A bridge girder refers to the part where people and vehicles pass. It is a major component of the bridge and is constructed using materials such as concrete and steel. Additionally, the impact on the bridge girder varies significantly depending on the scale of the bridge and the environment in which it is installed. Therefore, there are various types of bridge girders designed to accommodate these factors, each with its own characteristics. This article introduces what a bridge girder refers to, accompanied by illustrations. It also summarizes the types and structures of bridge girders, so please use it as foundational knowledge about bridges. *For detailed content of the column, you can view it through the related links.

Company information
CRETEC, a company under Crittec Industries, was born from the combination of Create (creation) and Technology. As a comprehensive manufacturer of bridge expansion devices, we continue to develop expansion devices that contribute to the longevity of bridges and environmental protection. Moreover, we do not stop at product manufacturing; by consistently handling everything from research, design, manufacturing, sales, to construction in-house, we can manufacture and install expansion devices that meet the requests of our clients and general contractors, as well as the conditions and environments of the bridges and roads on-site. We also take into account the issues that arise during the installation of expansion devices and the damage conditions of existing devices that are removed, using this information to improve and develop our products. Please feel free to contact us for inquiries about bridge expansion devices, requests for materials, or estimates. ◆ What is a bridge expansion device? It is a component installed in the gap between the bridge abutment and the bridge girder, or between bridge girders. When designing a bridge, it is necessary to create a gap to prevent the bridge girders from colliding due to expansion and contraction caused by temperature changes. The bridge expansion device is required to cover this gap and ensure safe passage for vehicles and pedestrians.
