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 kind of welding rod should be used for rail and Q235A welding?
MG600 welding rod can be used for rail and Q235A welding.
Q:55Q rail performance
Rail is the main component of railway track. Its function is to guide the wheel of the rolling stock, to bear the great pressure of the wheel and to deliver it to the sleeper. 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.
Q:What type of rail is the main type used on the railway?
The standard track length is 12.50 meters and 25 meters in two, the laying of the curve rail, slightly shorter length, 12.46 meters, 12.42 meters and 24.96 meters, 24.92 meters and other rail, general specification for 38, 43, 45, 50, 60 (kg / m).
Q:Why is the thermit reaction welded to rails instead of welded rails?
Steel contains other added elements, while the thermit reaction produces only iron.
Q:Seamless rail is not afraid of expansion and contraction?
Seamless rail not thousands of kilometers without gaps, but the 25 meter long rail welding up into hundreds of metres long or even thousands of meters long, and then in the shop on the embankment, or the gap between 11 mm and a section of a seamless rail, now Shanghai Nanjing line is 303 km long ultra long seamless rail, seamless rail in order to solve the thermal expansion and contraction by slot number is not enough, now solve the thermal expansion and contraction in two ways, one is the long rail itself under all temperature stress, will be locked in the long rail sleepers, which is due to temperature change and contraction, this method is suitable for a year four small temperature difference areas, for example in the south of China. In some temperature difference regions should take another approach, namely the long rail itself does not bear the temperature stress, and stress or regular bleeding stress to automatic bleeding Method, make the long rail with temperature rise and free shrinkage, at the time of laying also try to choose the optimum temperature of the rail laying, the expansion value in the minimum range, so that regardless of the temperature rising or falling, the rail expansion always control at a minimum.
Q:Why is rail insulated?
Rail is the main component of railway track. Its function is to guide the wheel of the rolling stock, to bear the great pressure of the wheel and to deliver it to the sleeper.
Q:The previous track is seamed, there is no gap, is how to achieve
Seamless rail not thousands of kilometers without gaps, but the 25 meter long rail welding up into hundreds of metres long or even thousands of meters long, and then in the shop on the embankment, or the gap between 11 mm and a section of a seamless rail, now Shanghai Nanjing line is 303 km long ultra long seamless rail. Seamless rail to solve the thermal expansion and contraction by slot number is not enough, now solve the thermal expansion and contraction in two ways: one is the long rail itself under all temperature stress, will be locked in the long rail sleepers, which is due to temperature change and contraction, this method is suitable for throughout the year the temperature is almost the same as in the southern region, Chinese. In some temperature difference regions should take another approach, namely the long rail itself does not bear the temperature stress, and stress or regular bleeding stress to automatic bleeding, make the long rail with temperature rise and free shrinkage, at the time of laying also try to choose the best temperature of laying the rail expansion value in the minimum range, so that regardless of temperature rising or falling, the rail expansion always control in the smallest range.
Q:Why should there be a gap between the rails?
After laying the rails, the wood seems to swell and the rails will jump up.To prevent the heat from rising and cold contraction, the two rails have strong pressure on each other, thus damaging the rail. So there must be a gap between the rails.
Q:Why are the rails made of I-beam?
The rails are made of type H steel, one of i-beam.
Q:What's the difference between a hot rail and a heat treated rail?
Surface heat treatment, such as surface hardening. There is still a difference, but for the same material, heat treatment is the same.
