30kg Heat Treated Light Steel Rail

The "30kg" here means that the weight of each meter of track is 30 kilograms. This is a standard specification used to measure the strength and load-bearing capacity of the track. The weight of the track is usually expressed in kilograms per meter, which makes it easy to classify and compare the tracks.

Hot rolling is a metal processing technique. It heats metal at high temperatures and shapes it through rolling. In rail production, the hot rolling process helps to improve the strength, toughness, and wear resistance of the rail, enabling it to withstand high-intensity pressure and friction.

Light rail generally refers to the tracks used in urban rail transit systems such as subways, light rails, etc. Compared to heavy rail, the design and weight of light rail are usually lighter, suitable for lighter vehicles and lower load requirements. 30kg light rail is generally used in urban light rail, low-speed railway, industrial railway and other fields.

Comparison with other types of steel rails

The theoretical weight per meter of a 30kg light rail is about 30 kilograms, which is one of its prominent markings. Light rails of different weights also vary in size. Generally speaking, the rail height, bottom width, head width, and other dimensions of a 30kg light rail are relatively moderate. For example, the rail height is usually around 120mm, the bottom width is about 100mm, and the head width is about 60mm.

Other types of light rail, such as 22kg light rail, have a lighter weight per meter, and the corresponding track size may be slightly smaller. The track height, bottom width, head width, and other dimensions will be designed according to their load-bearing capacity and usage scenarios. The track height may be around 100mm, bottom width may be around 85mm, and head width may be around 50mm. The 43kg light rail has a heavier weight per meter and a larger size, with a rail height of about 140mm, a bottom width of about 110mm, and a head width of about 70mm.
