Applications of MS Channel:

The MS Channel can be applied to construction of warehouses, workshops, sport stadiums and car parks etc.The hot rolled channel steel belongs to carbon structural steel which is applied to in the field of construction and machinery.In details, the hot rolled channel steel is usually used for arch-itechtural structure, and they could be welded in order to support or hang a vari-ety of facilities. They are also usually used in combination with I beam. Generally,the hot rolled channel steel we supply must possess perfect welding property, riveting property and mechanical property and so on.

Package & Delivery of MS Channel:

1.The hot rolled channel steel will be packed in bundle with steel wire at each end of every bundle and color marking in order to help the customer to recognize his goods more easily at sight.

2. And the hot rolled channel steel could be loaded into 20ft or 40ft container, or by bulk cargo.If the weight of each bundle reaches more than 3.5 mt, the loading by break bulk cargo should be choosed.When the weight of each bundle reaches less than 3mt, the loading by container should be choosed.

3.As for the transportaion from mill to loading port, the truck will be usually used. And the maximum quantity for each truck is 40mt.

4.All in all, we could do in accordance with customer's request

Q:The total floor distribution along the wall surface 40x4 galvanized flat steel, flat paint is painted yellow mark or brush a straight chute
Hello, the exterior paint of the distribution room can brush green, or other light colored series, shades of light and shade
Q:How to determine the application direction of steel grid plate
This order must be strict and clear. The steel grid plate in the length direction (flat length direction) on at both ends of a supporting beam, i.e. use or the use of slot, and ends in the width direction can not need support. Because the bearing capacity of steel plate mainly from the flat direction. For example drain cover
Q:The difference between galvanized flat steel 40*4 and galvanized flat steel 80*8 is the difference on the material list!
There are many kinds of flat steel, Q235A/B/C, mainly depends on the location of your specific requirements, what is needed?;
Q:How can copper clad steel ground electrode and galvanized flat steel be welded?
If you want it to work well, use heat release welding, and if you take into account the cost budget, there are connectors, connectors that are just mechanical connections
Q:Where is the use of flat steel in electrical use?
The main use of galvanized grounding in building electric device, equipotential connection, such as transformer neutral point grounding, power distribution cabinet repeatedly grounding of electrical equipment and protective metal pipeline grounding and equipotential connection of buildings, building the underground lightning belt (that is the root of a plurality of buried steel the grounding electrode connected), building lightning deflectors and high-rise building equalizing ring (without using the building structure reinforcement), cable bracket (laminated cable trench or substation room or subway) or slot (or tray tray) metal grounding connection, welding and in the use of bolt connection, look to determine the design requirements and conditions, generally buried (wall) welding used in concrete or concealed, must be at least three surface welding, welding (two flat lap length Larger than the width of flat steel 2.2-2.5 times, round steel and flat steel lap length is greater than round steel 6-8 times, welding mouth does not allow slag, meat and remove welding slag, welding finished, in addition to concrete, do anti-corrosion, rust prevention;
Q:What is the difference between flat steel and steel strip?
It belongs to the conventional flat stainless steel series, steel to stainless steel sheet series, steel is cold rolled sheet, and a flat surface of hot rolled and cold rolled surface, flat iron is a common type of steel does not contain nickel, but sometimes some customers habitually called stainless steel flat steel flat iron.
Q:What's the difference between hot rolled flat steel and flat rolling tool flat steel?
Hot rolled flat steel rolling tools - tool steel, commonly used for measuring and cutting tools with what. Material is tool steel, such as carbon tool steel (T8, T10), alloy tool steel (Cr12MoV), high-speed steel, etc..
Q:What is the rolling range of the micro cold rolled flat steel production line?
Cold rolled steel flat steel, width 12-300mm, thickness 4-60mm, cross section is rectangular and with pure edge of steel. Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling. Section steel is one of the four major steel products (plate, tube, mould, wire). According to the section shape, the section steel is divided into simple section steel and complex section steel (deformed steel). The former refers to the steel, round steel, flat steel, angle steel, six angle steel; the latter refers to the I-beam, channel steel, steel, steel, steel frame bending etc..
Q:Is there a requirement for the ground resistance of the field motor? Is it good to use ground flat steel or ground wire?
The enclosure is grounded and the ground wire is the same, and the ground wire requirement is no more than 4 ohms. Generally, the motor shell can be connected to zero. There is no need to ground. In the power system, earthing and zeroing can not be mixed.
Q:Does the cable trench need grounding?
Cable trench grounding practices: ground pile using hot galvanized steel angle (50X5X2500), every 20 meters to hit a root. The pile top is 0.6 meters away from the ground, and the ground wire is made of galvanized steel flat bar (40X4). Cable grounding wire and cable groove on both sides of the main frame by welding, every 20 meters will ground wire leads and grounding pile welding, while the grounding cable trench on both sides of the ditch bottom connection, grounding wire used for 10 hot dip galvanized steel. All grounding devices need to be welded firmly at the joint, and the welding place is treated with asphalt.
