Specifications of Standard Size Steel Channel Bar, Metal Channel Bar

1.Our company enjoys high reputation on manufacturing and supplying U channel steel. Among those steel products, the U channel steel as per japanese, chinese and european can be regarded as our  primary products.

Under those standard, the material grade includes: GB Q235B,GB Q345B/JIS G3192, SS400/EN 10025,S235JR and so on.

Here,the U channel steel as per japanese standard is posted just as reference.

2. Dimension Figure:

 

Note:1.The height ranges from 50mm to 300mm

    2.The breadth ranges from 25mm to 89mm

    3.Theoretically speaking, the flange of U channel steel should bear stress, it’s to say that the U channel should be upright rather than lying under construction. Therefore, we strictly control the tolerance of the flange thickness.

3.The sections of U Channel Steel as per JIS Standard are shown in the below table:

Note: we are also competent to supply structure steel u channel as per other sections, which depends on the customer's requirements for the quantity.

Applications of Standard Size Steel Channel Bar, Metal Channel Bar

U channel steel could be regarded as carbon steel or plain steel. Typically, it is stiff and strong. Carbon steels do rust easily, but they can be easily painted or primed. They are cheap so they are the normal choice for most fabrications. U channel steel is often used as supporting members, most commonly in the house raising industry to strengthen timber bears under houses. Transmission line towers.

And our products are widely used in Architectural ConstructionsTelecom towerSub Station StructureMicrowave tower Factory and warehousing shedElectrification projects, poles and earthing E.O.T. cranesMaterial handling equipmentsShip buildingAutomobile

Package & Delivery of Standard Size Steel Channel Bar, Metal Channel Bar

The u 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.

And u channel steel could be loaded into 20ft or 40ft container, or by bulk cargo. If the weight of each bundle reaches less 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.

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

In a word, we do try our best to satisfy all the customer's requirements.

U Channel Steel

Production Flow of Standard Size Steel Channel Bar, Metal Channel Bar

1.The steel billet shall be heated in the high temperature furnace.

2. The heated steel billet shall be rolled five to nine times with the aim of shaping the general figure of steel u channel.

3. The rolled steel u channel should be put onto the cooling bed to make the temperature low.

4. The steel u channel should be straighted on the straightener.

5. The straighted steel u channel will be cut into meters by saw, as per customer's requirements.

Q:What is the difference between galvanized steel bar and ordinary angle iron?
Plain angle ironThe surface quality of ordinary angle iron is stipulated in the standard, and no harmful defects such as layering, scab and cracks are required.The allowable range of the geometric deviation of the angle iron is also stipulated in the standard. The bending angle, the width of the edge, the edge thickness, the vertex angle and the theoretical weight are generally included, and the angle steel must not be significantly reversed.Angle steel is a kind of carbon structural steel for construction. It is a simple section steel, mainly used in the frame of metal component and workshop. In use, better weldability, plastic deformation and mechanical strength are required. The raw steel billet for producing angle steel is low carbon square billet, and the finished product angle iron is made by hot rolling, normalizing or hot rolling.
Q:Unequal angle steel
Unequal angle steel: in the field of engineering materials, relative to two equal side length equal angles, refers to the section of the right angle, L shaped, and unequal length of both sides of the angle. It is widely used in engineering structure, structure and variety of municipal public utilities, civil and military industries, such as industrial beams, bridges, towers, hoisting and conveying machinery, ships, industrial furnace, reaction tower, container frame, and warehouses, because the amount is less than the unilateral angle, so the relative price slightly higher.
Q:304 what does angle iron stand for?
304 stainless steel, consisting of 18Cr-9Ni, is the most widely used stainless steel and heat resistant steel. Used in food production equipment, chemical equipment, nuclear energy, etc..
Q:What's the size of the 50 angle iron?
Specification for 50 equal anglesTwo sides at right angles, 90 degrees. The length of the side is 50mm, and the thickness of the edge is 3mm, 4mm, 5mm and 6mm. The corresponding weight of each meter is 2.332 kg, 3.059 kg, 3.770 kg, 4.465 kg, respectively, four kg.
Q:What is angle iron?
Standard Specification for hot-rolled equal angle iron is 2#-20#. It can be divided into two kinds of equilateral angle steel and unequal angle steel, among which unequal angle steel can be divided into two kinds: unequal thickness, unequal thickness and unequal thickness. The dimension of angle iron is expressed by the dimension of the length of side and the thickness of edge. At present, the domestic steel specifications for 2 - 20 cm, to length number number, the same horn steel often have 2 - 7 different edge thickness. Imported steel angles indicate the actual sizes and edges of both sides and indicate the relevant standards. Generally, the length of 12.5cm is larger than that of angle steel, and between 12.5cm and 5cm is medium angle steel. The angle of 5cm is smaller than that of angle steel.
Q:Decoration materials and what is the difference between the angle steel bracket.
The difference between decoration materials and the angle steel angle: angle is the angle of cut into the length of the 30~50mm angle, mainly used for dry hanging stone etc.. Angle steel is used for steel structure parts, angle iron keel welding.
Q:Bearing capacity of angle steel and channel steel
According to the channel shape and can be divided into 4 kinds: cold bending equilateral channels, cold-formed non equilateral channel steel, cold rolled edge channels, the cold bending edge channels.According to the theory of steel structure, it should be stressed by the channel plate, that is to say, the channel should stand rather than lie prone.
Q:What is the keel of the aluminum single board suspended or the welded frame of angle steel?
Light steel keel, is a kind of new building materials, with the rapid development of China's modernization construction, light steel keel is widely used in hotels, airport lounges, car transport station, station, amusement parks, shopping malls, factories, office buildings, building renovation, interior decoration, ceiling set of old buildings and other places. Light steel (paint) keel ceiling has light weight, high strength, adapt to waterproof, shock, dust, sound insulation, sound absorption, constant temperature and other effects, but also has the advantages of short construction period, simple construction and so on.
Q:What is the corresponding length of the root weight in the angle standard?
First, the classification of profiles1. simple section steelThe square - hot rolled steel, cold drawn steel; the round - rolled bar, forging round steel, cold drawn steelThe flat steel wire; 4; 5 - 6 - spring flat steel; equal angle steel, equilateral angle steel and steel triangle;The six angle to the bow; steel; elliptical steel2. complex section steelI-beam -- ordinary I-beam, light I-beamChannel steel -- hot rolled channel (ordinary channel steel, light channel steel), bent channel steelThird, H steel (also known as wide leg I-beam)Rail - heavy rail, light rail, crane rail, other special railSash steelThe steel sheet pile
Q:100 x 100 x 10 equal angle steel, per meter weight?
Angle steel is a kind of carbon structural steel for construction. It is a simple section steel, mainly used in the frame of metal component and workshop. In use, better weldability, plastic deformation and mechanical strength are required. The raw steel billet for producing angle steel is low carbon square billet, and the finished product angle iron is made by hot rolling, normalizing or hot rolling.
