Applications of UPN Channel Steel:

The UPN Channel Steel 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.

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:Does anyone know how to calculate the volume of channel steel?
Theoretical calculations can be used: sectional area * length. There are sectional sizes in the specifications of channel steel labels. The sectional area and volume shall be calculated first. When measuring the sectional area, the grid paper can be used. Of course, the accuracy is limited.
Q:In the steel structure of steel purlin 160*60*20*2.5 what mean?
160mm tall, 60mm wide, 2.5mm thick20mm is the size of two small ears. It's called C shape steel.2.5 of the proportion is 5.87kg/m
Q:6.3# how long is the channel length?
Standard Specification for dimensions, weights and specifications for hot rolled ordinary channel steels:6.3# channel steel *6/7/8/9 meters hot rolled channel 63*40*4.8 length length, the specific data can refer to the following table painted red line.
Q:Geometrical dimension of channel steel channel 8
GB material. Now a lot of non-standard (lower tolerance. National standard difference 5~7%)
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:What material is channel steel?
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 for building structures, vehicle manufacturing, other industrial structures and fixed plates, cabinets, etc., and channel steel is often used in conjunction with i-beam.
Q:How are the types of I-beam and channel ABC distinguished? Tell me about it, please.
According to the steel height, waist width, waist thickness to distinguish, C type thickness, thickness is thickest, weight is heaviest
Q:Could you tell me the theoretical weight and size of 16 and 18 channel steel?

Q:Do you have any width 20 cm wide? What's the model number and how much is it?
20Cm high hot-rolled ordinary channel, there is no width of 20cm, but can do cold bending.
