Usages of Light Steel Rail GB 9kg GB12kg GB15kg with High Quality:

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 Light Steel Rail GB 9kg GB12kg GB15kg with High Quality:

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 Light Steel Rail GB 9kg GB12kg GB15kg with High Quality:

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: How soon can we receive the product after purchase?

A1: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.

Q2: Can stainless steel rust?

A2: 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.

Q3: Why buy Materials & Equipment from OKorder.com?

A3: 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.

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:What are the contents of the rail approach?
Is the base of the welded rail or the field of the laying line?.
Q:Name the basic structure and function of the rail
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 is the difference between the rail lead line and the rail connection line?
The rail line orbit must use different types of profiled rail connection:1, different types of rail size is not the same, to ensure that the two types of rail between the reliable connection, and rail top surface and so on, we must use special-shaped joints.2, special-shaped joints are divided into two kinds: one is between different types of rail using special-shaped plywood, this way is extremely easy to damage; the other is the use of special-shaped rail, that is, a rail is divided into two parts.
Q:Why is rail insulated?
Rails are used as signal return lines, so insulation must be made to prevent stray current interference.
Q:What's the difference between a high-speed rail and an ordinary one?
Not only does the train speed run faster than the train, but the infrastructure (track, signal, communication and catenary) of the train also meets the technical requirements of the speed grade.
Q:Is the rail of the railway made of steel? Or iron or iron?
Rail is a forging, steel and iron are essentially different from the amount of carbon content. The carbon content of steel is 0. 0218%-2. Between 11%, the carbon content of the cast iron is 2. 11%-6. 69%.Such as a rail model is: 60U71MN, the rail belongs to manganese steel 60, indicating that the weight is 60KG/mU71 means 0.71% carbon content
Q:How to solve the problem of thermal expansion and cold contraction of railway 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.
Q:What is called orbital angle?
It is a major component of a 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 difference between a hot rail and a heat treated rail?
The hot rolling is equivalent to the annealed state, while the heat treatment is divided into many kinds, the whole heat treatment, annealing, tempering, normalizing, quenching, chemical heat treatment, carburizing and nitriding;
