Steel Rail

The type of Steel Rails is expressed in kilograms per meter of rail mass.

Kingrail can supply the steel rails used for general speed railway track with 160km/h,high speed railway track with 250km/h and 350km/h and profile from 37kg/m-75kg/m according to customers’ requirements. At the same time,we can supply Light rail, Heavy rail, switch rail, crane rail, I-Beam Rail, U-Beam Rail, etc...

1. Heavy rail: A heavy rail is a steel rail with a nominal weight of more than 20kg per meter. Train rails and crane rails are all heavy rails.

The main purpose of heavy rail: heavy rail is suitable for laying the tracks of the main line, non-main line, curve and tunnel of the railway. It can also be used for the track of construction tower cranes and other cranes.

2. Light rail (GB1264-89) is a steel rail with a nominal weight of less than or equal to 30kg per meter. The quality requirement of light rail is lower than that of heavy rail, and it only requires inspection of its chemical composition, tensile strength, hardness and drop weight test.

The main purpose of light rail: light rail is mainly used for laying temporary transportation lines and lines for light locomotives in forest areas, mining areas, factories and construction sites.

3. Crane rails (GB3426-82) Crane rails are crane rails. Compared with train rails, their height is lower, but the head width and waist thickness are larger. In my country, crane rails are included in the heavy rail category, and the quality requirements Only require inspection of chemical composition and tensile strength.

Main purpose of crane rail: used to lay crane rails and trolley rails.

(1) The rolled steel rail should be straight without any significant bending or twisting. The local bending and torsion of light and heavy rails, as well as the amount of correction deformation, and the inclination of rail end faces, shall not exceed the standard.

(2) The surface of the rail should be clean and smooth, free of defects such as cracks, scars, scratches, etc.; there should be no shrinkage marks and interlayers on the end surface. The allowable defects on the overall surface of the light and heavy rail and the extent of their geometric quantities shall not exceed the standard.

(1) Each heavy rail is rolled with a clear raised mark at its specified position: manufacturer's logo, steel number, furnace number, model number, manufacturing year (month) number. There are the words "A", "Z" and white paint that express specific meanings.

(2) Light rails delivered in bundles should be marked with a lot number.

(3) The content of the quality certificate of the steel rail shall be in accordance with the provisions of (12) in "8".

(1) The arrival of the goods shall be strictly in accordance with the contract and the annex, and the general inspection of quality control shall be completed within the claim period.

(2) During the quality assurance period of the rail, attention should be paid to the quality change of the rail. In recent years, there have been several claims for quality problems in the actual operation and use of imported steel rails. The inspection and quarantine agency used ultrasonic flaw detection and other testing methods to identify defects such as internal rail cracks and rail surface stripping. After issuing inspection and quarantine certificates, significant claims were obtained.

As an ISO 9001 certified company,Kingrail Parts has built the intensive quality control networks, established strict rules and inspection standards.We only assigned professional and experienced staffs during the whole procedure as the key resource of the quality control.
