Applications of Cold-Rolled C Channel Bar:

The Cold-Rolled C Channel Bar 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 Cold-Rolled C Channel Bar:

Q:In the construction engineering construction site, such as channel material piled reinforced why mat wood, directly on the concrete floor (ground) on the surface is not?
1. Prevent rust.2. Keep the component clean and non clay. Otherwise, the rain will take enough time to clean the components.3. Convenient transportation. When the component is high, it is convenient to wear a steel rope to bind, a bundle of steel bars, the transportation efficiency is high; you put the steel bar directly on the ground, and later inconvenient to transport by crane, can only move out one by one.
Q:I want to know what kind of steel is this type of steel, such as channel steel and die steel?
Channel steel is Q235 and die steel is alloy steel
Q:What's the name of channel steel?
Channel steel is divided into ordinary channel steel and light channel steel.Again: according to different shapes, they 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.
Q:Is channel steel cold rolled or hot rolled?
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
Q:Channel 20A? What's the matter?
Channel steel, 20#A specification, 200*73*7.0 theory, weight 22.637
Q:How do you calculate the weight of 100 channel steel?
If it is GB, the channel can be checked by the hardware manual sheet, and the weight is multiplied by the length of each meter, that is, its weight.
Q:What's the difference between channel type 25a#, 25b# and 25c#?
Channel steel is a strip of steel with a cross section. The specifications of the method, such as 120*53*5, mean waist height of 120 mm, leg width of 53 mm channel, waist thickness of 5 mm channel, or called 12# channel. The same height of the channel, if there are several different leg width and waist thickness, also need to add a, B, C on the right side of the model, such as 25a#, 25b#, 25c# and so on. Channel steel is divided into ordinary channel steel and light channel steel. Standard Specification for hot-rolled plain channel steel is 5-40#. Specifications for hot rolled flexible channel steel supplied by supply and demand agreement are 6.5-30#. Channel steel is mainly used in building structures, vehicle manufacturing and other industrial structures, and channel steel is often used in conjunction with i-beam.
Q:Specification for channel steels used in fork trucks
General 8 ton forklift optional Q235B 28 a channel, because now the steel rolling generally negative difference, suggested a 30 channel, if the Q345B material, a 25 channel.
Q:What standard is channel steel 250*90*9?
Channel steel: the channel steel is a long strip steel with a cross section. Its specification means: such as 120*53*5, which means that the waist height is 120 millimeters, the width of the leg is 53 millimeters of channel, the waist is 5 mm thick channel, or called 12# channel steel. The same height of the channel, if there are several different leg width and waist thickness, also need to add a, B, C on the right side of the model to distinguish, such as 25a#, 25b#, 25c# and so on.
Q:What material does hot-dip galvanized channel belong to?
Channel steel is only galvanized galvanized steel when it is galvanized. Hot dip galvanizing, cold galvanizing.Domestic commonly used channel material for Q235 and Q345.
JANG is a professional company specilized in cold bend angle, cold bend U channel and other cold formed sectional steel. Since the established of our company, we aimed to provide the customers qualified product with good price and convenient service.
