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 Rail, Hot Rolled, GB, DIN, AREMA, JIS, BS, UIC for Sale:

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.

FAQ:

Q1: Why buy Materials & Equipment from OKorder.com?

A1: All products offered by OKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

Q2: What makes stainless steel stainless?

A2: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q3: Can stainless steel rust?

A3: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

Q:What is a rail flaw detector used to detect?
The rail can be detected by frequency modulation or pulse type flaw detector. The frequency modulation type can only detect the defects parallel to the rail surface, and the pulse type can detect the type defects. Longitudinal and transverse waves can be used to detect defects in different directions of rails. With flat probe and oblique probe in different parts of the rail detection waveform, as shown below. The position and direction of the probe are measured as the weld line is detected. Head on both sides with 35 degree oblique probe, and rail waist rail with 50 degree oblique probe.
Q:What are the contents of the rail approach?
Is the base of the welded rail or the field of the laying line?.
Q:The difference between small resistance and constant resistance fastener of high speed rail
The railway line to solve the rail expansion and contraction method is generally used for fastening the way, is the shrapnel into spring fastener fastener (also called spring bar fastener), rail tightly in the sleepers, forcibly will produce thermal expansion and contraction of the energy to digest, but the existence of such a problem is generated when the thermal expansion and contraction energy is greater than the distance unit of sleeper rail adhesion, makes up the phenomenon of rail, rail sleeper unit length twist. In order to solve this problem, the railway department within a certain distance, playing a few holes in the rail waist to release the energy generated by thermal expansion and contraction, and within a certain distance (about 1500m) retaining rail joint, to assist in releasing the energy generated by the thermal expansion and contraction, in order to solve the problem of rail expansion and contraction. First of all, the first point is that the steel of the rail is not made in China, all of them are imported, and the quality of the rail is guaranteed to the maximum extent.
Q:High iron seamless rail is how to solve the problem of the thermal contraction account?
The rail temperature force is used on the railway line to lock the track with strong line resistance, which limits the free expansion of the rail. In our country, we use high strength bolts, gusset fasteners or elastic fasteners to restrict the rail. In order to reduce the temperature force of the rail, the line should be locked when the rail is at the right temperature. The local maximum rail temperature is used to lock the rail temperature with the lowest rail temperature above the average height.
Q:What is rail thermit welding?
The so-called thermit welding, the two rails are connected by method of aluminium heat welding, thus forming a seamless rail, improve the safety of the train, the passengers didn't hear the click, click the train rail joint sound.
Q:Why should there be a gap between the two railway tracks?
Another relatively new way of connecting rails is the continuous welded rail (Continuous, Welded, Rail, CWR), also known as seamless rails or long welded rails. This method couples several kilometers of rails together to form a continuous line. Because there is no seam, the strength of the track increases, less maintenance is needed, and the vehicle runs more smoothly.The cost of welded rails is more expensive than that of a fish board. But because of the high strength, the vehicle can travel at a higher speed on the continuous welded track, and the friction force is reduced.
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:What are the three types of rail damage?
Rail damage refers to the occurrence of fracture, crack and other damage that affect the rail performance during the test. Rail damage is a prominent problem on the railway, and seriously affects the safety of traffic. Our country according to the damage types of rail, damage location and damage reasons of classification, is divided into 9 categories and 32 kinds of injuries, and two digit number, ten digit damage location and condition, a digit that causes damage.
Q:What railway tracks are also live?
The power supply technology is adopted in many cities abroad and in China, with the advantages of beautiful appearance, no visual obstacles of the electric pole and power supply line, and low maintenance cost. The supply rails are usually equipped with protective covers.
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.
