Invoicing on theoretical weight or actual weight as customer request

Payment terms: 30% advance payment by T/T, 70% payment against the copy of the B/L; 100% L/C at sight, etc.

Usages of Steel Heavy Rail with Multiple Specifications:

Light rail is mainly used in forest region, mines, factories and construction sites laid of the place such as temporary transport line and light motorcycles with line. Be widely used for railway, subway, transportation track, express, curve way, tunnel way and so on.

Packaging & Delivery of Steel Heavy Rail with Multiple Specifications:

1. Packing: it is nude packed in bundles by steel wire rod

2. Bundle weight: not more than 3.5MT for bulk vessel; less than 3 MT for container load

3. Marks:

Color marking: There will be color marking on both end of the bundle for the cargo delivered by bulk vessel. That makes it easily to distinguish at the destination port.

Tag mark: there will be tag mark tied up on the bundles. The information usually including supplier logo and name, product name, made in China, shipping marks and other information request by the customer.

If loading by container the marking is not needed, but we will prepare it as customer request.     

4. Transportation: the goods are delivered by truck from mill to loading port, the maximum quantity can be loaded is around 40MTs by each truck. If the order quantity cannot reach the full truck loaded, the transportation cost per ton will be little higher than full load.

5. Delivered by container or bulk vessel

6. Delivery Time: All the Hot Rolled Steel Rail will be transpoted at the port of Tianjin, China within 30 days after receiving the advance payment by T/T or the orginal L/C at sight.

Inspection of Steel Heavy Rail with Multiple Specifications:

We will send the MTC of the factory to the clients dirrectly which contain the anlisis of the heat, chemiqul composition, phisical characteristicas, etc.

And our inspectors will arrive at the factory to meke the inspection of the size, length, weight and quantity before the transportation from the factory.

Q:What is called orbital angle?
The rail must provide a continuous, smooth, and least resistant rolling surface for the wheel. In electrified railway or automatic block section, rail can also be used as track circuit. The rail can be divided into three kinds: crane rail (crane track), heavy rail and light rail.
Q:What is the upsetting amount of rail?
Upsetting is the amount of deformation produced during the top upsetting of the two rail to be welded.
Q:What is the working principle of a rail profilometer?
Two dimensional scanning sensor ZLDS200 series is a small range, high speed and high precision two-dimensional sensor, with digital, integrated structure. The two-dimensional laser sensor ZLDS200 series with high precision can reach Z per second, 0.1% 1200 axis scanning contour data of high response and high degree of protection IP67, and synchronization characteristics of high performance, and in addition to the standard series of products, can also be customized according to the user's special needs.
Q:Why should there be a gap between the two railway tracks?
There are many ways of connecting rails to rails. The most traditional method will be about twenty meters of rail fixed on the sleeper, the rail between the joint (also known as joint). The British habit, the two tracks will have connections in the same place, but the United States will be placed in different places. The joint is joined with a fish plate. It is a steel plate about sixty cm long, with four or six steel bolts at each end and a small hole used to tie the rail. There is a gap between the rails, approximately 6mm wide, called the expansion joint. Make a small hole of rail fishplate steel bolt through the oval, so you can have a space to expand the rail in hot weather. This is very important for rails: if there is no room for expansion, the rails will have to withstand 1.6 tons of stress or tension whenever the temperature changes for a while. If a place has an annual maximum and minimum temperature difference of thirty degrees, this force can reach fifty tons. A rail may therefore become askew and affect vehicle safety.
Q:The previous track is seamed, there is no gap, is how to achieve
The seamless rail technology in China has been developed independently. The first step is to weld each 25 meter long rail in the welded rail mill into 250 meters long rails, and then use the long rail train to the construction site and weld them into 1 to 2 km long rails. After that, the long rail is connected with a section of a rail, and the rail is firmly buckled on the sleeper by a fastener.
Q:The tracks on the stones have what effect?
The stones support the rails and concrete sleepers, while the force from the train passes evenly to the subgrade
Q:Why rail interface with?
A zigzag railway is joined by a rail of the same length. Where the rails are joined, there is always a gap for the expansion and elongation of the rail.
Q:What are the requirements of the two rails on the track?
At that level, the same section of line about two shares of the top surface of the rail height difference; line to line tolerance of 4mm, the other line is 6mm.
Q:Generally, how often do rail rails change?
But the passenger dedicated line, such as the Beijing-Shanghai high-speed railway, the Wuhan Guangzhou high-speed railway, the Beijing Tianjin Intercity Rail replacement, the cycle is very long, generally can reach ten years or even in the past 20 years, because of the high iron light axle load, line status, and problems of the rail wear less, low probability.
Q:Structural classification of rails
The type of rail is expressed by the mass kilogram of rail length per meter. The rails used in China's railways are 75kg/m, 60kg/m, 50kg/m, 43kg/m and 38kg/m.
