38kg Heavy Steel Rail U71Mn

"38kg" means that the weight of each meter of rail is 38 kilograms. 38kg heavy rail is a relatively heavy type of rail. Compared with light rail (such as 22kg, 18kg rail), 38kg rail has higher load-bearing capacity, durability and stability, and is suitable for railway environments with heavy loads.

The weight of 38kg rail is 38 kilograms per meter, which means that it is relatively heavy and can better share the pressure generated by train operation and reduce the deformation of the track.

38kg steel rail usually adopts the "head width and bottom width" design similar to heavy rail, so that the rail can disperse the pressure applied during passing and ensure the stability of the track.

38kg steel rail usually uses high-strength steel, such as alloy steel or high-quality carbon steel, and undergoes heat treatment process to enhance its bending resistance, compression resistance and wear resistance to meet the needs of high-intensity and high-frequency traffic.

Parameters of 38kg Heavy Rail

Application scenarios

1.Heavy-load railway:

38kg rails are often used in railway systems that transport heavy goods and can withstand the transportation of heavy objects such as large machinery, ore, coal, steel, etc.

2.High-speed railway:

In some high-speed railway systems, 38kg rails can also provide sufficient support for high-speed trains, especially in some economical or relatively early lines.

3.Long-distance passenger railway: Long-distance railway transportation, especially long-term and high-load railway lines, will also use 38kg rails to ensure the stability and safety of train operation.

4.Industrial railway: Dedicated railway systems of some large industrial enterprises, mines or steel mills will also use 38kg rails, especially when the transportation load in these places is large.

Heavy Steel Rail

1. Can you provide free samples?
A: Small samples (such as 10cm cut sections) can be provided, but the customer needs to bear the shipping costs. The sample fee will be refunded in subsequent orders.

2. How long is the production cycle?
A: Regular specifications are in sufficient stock and shipped within 7 days; customized specifications require 15-30 days (depending on the order volume).

3. How to treat the rails with corrosion?
A: Natural corrosion protection (bare rails), oiling for rust prevention, or galvanizing (extra cost) are optional. Galvanizing is recommended for heavy corrosion environments.

4. How to ensure the straightness and tolerance of the rails?

A: We use a fully automatic straightening machine with a straightness error of ≤0.5mm/m and a height/width tolerance that meets ISO standards of ±0.5mm.
