High-speed rail is an important means of transportation that runs through the north and south of my country. It has become an important channel for my country's economic development and an effective means of transportation that saves time and improves efficiency. In the process of laying high-speed rail, it is inevitable to cross rivers, mountain streams, and depressions. This is why the laying of high-speed bridges came into being. The manual maintenance platform of bridge supports is often laid with hot-dip galvanized steel gratings.

The common specifications of the steel grating plate for the bridge pier support platform of the high-speed railway are G255/40/100, G325/30/100, etc. Since the high-speed railway bridge pier support platform is in the wild environment, the steel grid plate is required to be corrosion-resistant and durable. This requires that the span and load of the steel grating must be within the standard range, otherwise it is easy to cause safety accidents. To achieve this, it is not important to ensure that the raw materials of the steel grating work platform are real materials. The specific steel grating height, plate thickness, and center distance are all required in detail. Steel gratings of different sizes There are strict standards for load and span.

The steel grating walkway platform has the characteristics of light weight, large bearing capacity, safety and non-slip, convenient installation and disassembly, material saving, beautiful appearance, etc., and has been widely used in some bridge maintenance platforms.
