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.

Steel Heavy Rail

Tag mark: there will be tag mark tied up on the bundles. The information usually including supplier logo and name, product name, size, length, grade, 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.

Q:Why not Rail Rail corrosion?
The friction force of railway locomotives, EMUs can advance the power comes from between the wheel and rail forces, so as long as there is a certain volume of the railway line, the rail surfaces are smooth and no traces of rust.
Q:Why can't stainless steel be used as rail?
Stainless steel prices are high. Of course, the cheaper the rail, the better. The price of stainless steel is about 3 times of that of iron
Q:The difference between small resistance and constant resistance fastener of high speed rail
The second point adopts the tight pull, that is, the fastening of the rail is more firmly fixed on the ballast bed with the new fastener, and the high-speed railway basically adopts the ballastless track technology, and the fastening performance is better than that of the common railway.
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:What's the gauge for the high speed rail?
At present, although most countries use 1435 mm wide gauge, there are still more than 30 different gauges. From narrow to wide, 610 mm, 762 mm, 891 mm, 1000 mm, 1067 mm, 1372 mm, 2141 mm, 1435 mm, 1524 mm, 1880 mm, mm mm, etc..
Q:High speed rail runs so many trains a day, what about rail wear?
Also, in the upper rail, the layer and is contacted with a wheel, is adding another metal, indium, it added to the rail on the part of the hardness of the case, even has some toughness, the train wheel is very important, it and the "tire" contact, the collision, there will be some flexibility, to ensure the safe operation of the train.
Q:What are the characteristics of a curved track compared with a straight one?
The design should be gradually increased from light to heavy principle, according to the road train design speed of main operation conditions and recent forecast volume in accordance with the provisions of table 2-1 selection.
Q:Discontinuous rail seamless rail effect
Seamless rail is also afraid of thermal expansion, cold contraction, but better than ordinary steel pipe. Thermal expansion and contraction are the laws of physics. When heated, the distance between molecules increases, and the rails extend. Similarly, cold contracts.
Q:What is called orbital angle?
Has the best bending performance of I-shaped section by section shape of rail, a rail, rail waist and rail base is composed of three parts (Figure). In order to make the rail better withstand the force from various aspects, and ensure the necessary strength conditions, the rail should have enough height, the head and the bottom should have enough area and height, the waist and the bottom should not be too thin.
