Product Applications:

1.The JIS U Channel Steel can be devided into two kinds, namely common channel steel and light channel steel. The sizes of hot rolled common channel steel range from 5# to 40#. Meanwhile, the channel steel can be divided into cold forming sectional equal channel steel, cold forming sectional unequal channel steel, cold forming inner edge channel steel and outer edge channel steel.

2.The JIS u 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. The channel steel with sizes under 14# is usually applied to construction engineering, as purline, while the channel steel with sizes above 16# is more likely to be used in building vehicle chassis structure and mechanical structure. Furthermore, the channel steel in sizes above 30# are target at building bridge structure, as tension bar.

3.In a word, the channel steel must possess perfect welding property, riveting property and mechanical property and so on.

FAQ:

Q1 How do we guarantee the quality of our products?

A1 We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.

Q2 How soon can we receive the product after purchase?

A2 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.

Q3 What makes stainless steel stainless?

A3 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.

Q:Does anyone know how to calculate the volume of channel steel?!
1, check out the books on Design of cross-sectional area multiplied by the length of2, if there is in kind, called weight divided by 7.85
Q:Duplex building intermediate layer with channel steel or cast well?
Double story building, intermediate layer with channel steel and cast in place each has advantages and disadvantages, the following detailed description:1 、 cast-in-placeAdvantages: strong, relatively sound insulationDisadvantages: self importantMethods: in the load-bearing wall planting steel, tied with steel, formwork, pouring 10~12cm, waiting for about 28 days molding (summer time is slightly shorter)
Q:Difference between light channel steel and ordinary channel steel
Channel steel is a kind of carbon structural steel used for construction and machinery. It is a complex section steel. Its cross section has a groove shape. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing, etc.. In use, it requires better welding, riveting performance and comprehensive mechanical properties.
Q:Channel structure, angle steel, I-beam and so on, if not painted, the impact on life?
Angle called angle, the steel strip is perpendicular to each other on both sides into the corner. There are equal angles and unequal angles. The two sides of an equal angle steel are equal in width. The specifications are expressed in millimeters of edge width * edge width * edge thickness. Such as "/ 30 x 30 x 3", that is 30 mm width equal angle, edge thickness of 3 mm. Also available models that model is the number of centimeters wide, such as angle 3#. The model does not mean the size of the different edges and sizes of the same model. Therefore, the width, the edge and the thickness of the angle iron should be filled out in the contract and other documents, so as not to be indicated by the model alone. Standard Specification for hot-rolled equal angle iron is 2#-20#. The angle iron can be made up of different force components according to the different structure, and can also be used as the connecting piece between the components. Widely used in a variety of architectural and engineering structures, such as beams, bridges, towers, hoisting and conveying machinery, ships, industrial furnace, reaction tower, container frame and warehouse.
Q:What material is 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 channelsAccording 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:Which is cheaper, the same size, ordinary channel steel and light channel steel? Price difference is not big?
Channel steel is now a lot of production, small businesses cheaper prices, but the election materials, such as: channel 14a is genuine, it is more expensive. 14C is cheaper, but there is a difference in wall thickness. It is recommended to use genuine goods. The material is guaranteed, Q235 and Q345B are different. Bending strength.
Q:Which bearing capacity is stronger
Both I-beam and channel steel should be used as beam members, and the bending moment can be greater than that of other kinds of materials under two weight conditions. Because when it is used as a beam, the stress produced by the bending moment is X type, the stress at the top and the lower part of the beam is maximum, and the middle part is smaller, while the I-beam and the channel steel are both the top and the bottom. On both sides of I-beam symmetrical shape, the stress is not eccentric, and channel forming easy, cheap, and their "strong bearing capacity, which is closely related with their size and shape, a special mechanical bending section coefficient We - shape coefficient in mechanics of materials, according to the size of the check material the manual, the who, who is that the" strong bearing capacity ", because the maximum stress of B beam and the bending moment is proportional to M, and the cross-section coefficient is inversely proportional to We.
Q:Specific difference between channel steel, cold-formed steel channel, hot plate and cold plate
Cold bend channel steel and cold-rolled steel plate production process is basically the same, refers to the steel at normal temperature, through the external role of the steel rolled or bent into the required shape.
Q:Is the crane telescopic arm welded by channel steel or by square tube?
Steel welding steel mostly used as a beam or a column, the steel plate is relatively thick, and the channel has been forming calculation immunity anti disturbance capability is greatly improved, two only in the center position of weld line position, the formation of the moment theory on the bending of the analysis should be small and therefore, whether it is welding crack or welding deformation can better handle. In no case have to supply square, to be.
Q:Cautions for surface zinc spraying on channel steel
Thermal spraying principle summary is the first use of high pressure air pipe and the sand blown to the surface of the metal workpiece surface to remove rust and oxide skin on the surface, at the same time by increasing the absorption for Ma thermal spray coating, and then use oxygen, acetylene or electric heat source (large workpieces with electric heating, and the type of oxygen and acetylene by heating) compressed air and special tools (gun) to ultra high speed jet atomization of zinc to the metal surface.
