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:Discontinuous rail seamless rail effect
The rail welding seamless rail is 25 meters long up into several hundred meters or even thousands of meters long, and then put on the roadbed, seamless rail gap of 11 mm between each segment. Seamless rail is seamed, will also be affected.
Q:What is the connection of the rail joint?
The intermediate connecting parts, also called fasteners, have different combinations according to the different types of sleepers used. The wooden, including ordinary spike and iron plate. The advantage of this kind of fastener is less parts, easy installation, but little effort. In order to improve the performance of wooden, many countries use screw spike or spring instead of ordinary spike spike, or use a variety of different types of fastener on the concrete sleeper has been effective. The concrete sleeper fastening, including anchor bolts, iron plate, fastening piece and an elastic cushion (a) anchor bolt. For fastening fastening parts by anchoring various methods. The use of China on the railway is a sulfur anchor mix of sulphur, sand, cement and wax mixture is melted into colloid, injected into the reserved hole in the sleeper, as the fixed anchor bolt medium, pulling resistance, durability and insulation performance are very good. (b) iron backing plate. The utility model can disperse the vertical pressure of the rail, and after adding the shoulder, the transverse force transmitted by the rail can be partly taken, but because the compressive strength of the concrete sleeper is very large, the utility model can not be arranged in general. (c) fastening parts. There are two types of rigidity and elasticity. Rigid fastening parts mainly for buckle type; elastic fastening parts are spring and bar use plate elastic strip type two. (d) elastic cushion. When the train passes, the utility model can buffer and reduce vibration, and can improve the insulation performance of the concrete sleeper. Rubber backing plate, plastic backing plate, cork rubber backing plate and wood backing plate etc., and rubber backing plate is the best.
Q:How do seamless rails solve thermal stress problems?
Seamless line is not entirely seamless, but this gap is pulled very longOrdinary line every 25 meters, one rail seam, seamless rail with long rail and long rail, almost every 1 kilometers to set a rail seam. This rail joint is used to solve the temperature stress as common rail joints
Q:What is the upsetting amount of rail?
Top forging is a very important link in the welding process of rails. The link is to increase the feeding force, so that rail rapid delivery, so as to achieve the elimination of debris, eliminate defects, forming a good welding process.
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 difference between small resistance and constant resistance fastener of high speed rail
The three is in the construction of track laying, try to choose the season or time period and the minimum impact on the rail expansion, thus laying up, the problem will be a small part of.The Beijing Tianjin high-speed railway is now built long seamless rail, only the seams in the station area will be two to switch between stations, rail unit as a observation unit, each unit in the rail on both sides of the shoulder is buried with observation pile, regularly to crawl to measure the rail unit, when the amount of abnormal (also crawling is the internal stress anomaly), the need for stress relief construction, stress relief through elimination of rail because stress caused by the abnormal thermal expansion and contraction.
Q:What are the contents of the rail approach?
If you are into the rail welding base, to the selection of rail (rail according to the different choices of different welding tasks), welding inspection (inspection of rail in rail transport process has no damage), before steel rail welding straightening (rail end bend straightening), rust before welding (rail end, rail top surface, bottom of rail welding, prepare welding is left).
Q:What kind of rail needs polishing?
After the opening and operation of rail traffic, rail is long-term in the bad environment, because the train dynamic effect, the natural environment and the quality of rail rail itself and other reasons, often happen damage, such as cracks, wear and other phenomena, resulting in reduced maintenance work, rail service life, increased maintenance costs increase, or even seriously affected traffic safety.
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:Why is there a gap between each rail on the railway?
In summer, the rails are heated and inflated, leaving gaps to prevent accidents. In winter, the tracks freeze and leave gaps to prevent broken rails, and the gap can act as a general solution.
