- Q:Difference between steel channel and channel steel!
- Steel trough is made of cold rolled steel plate, channel steel is used by rolling mills and billets rolled out of products.
- Q:You can use steel purlin
- Not the best, I remember the US steel purlin is C, also called C purlin, around 2MM made of iron, and steel, the weight is too large, the roof girder pressure is too large, and too wasteful.
- Q:Channel 10, 1 meters. What is the theoretical weight?
- Channel 10, 1 meters, theoretical weight is 10.007kg.
- Q:How many pieces of channel steel?
- The raw material steel billet for channel steel is carbon or low alloy steel billets with a carbon content of not more than 0.25%. The finished channel steel is delivered by hot forming, normalizing or hot rolling. The specifications are shown in terms of waist height (H) * leg width (b) * and waist thickness (d) mm.
- Q:8# what's the size of the channel steel?
- 8# channel steel size 80*43*5mm
- Q:The parameters of the channel steel of Q235B
- Q235B is carbon structural steelIt consists of Q+ numeral + quality grade symbol + deoxidization method symbol. The steel dubbed "Q", representing the yield point of steel, behind the digital representation of the yield point value, in units of MPa such as Q235 (s) said the yield point for carbon steel 235 MPa. The necessary grades can be marked behind said deoxidation methods of quality grades and symbols. The quality class symbols are A, B, C, and D respectively. Deoxidation method notation: F means boiling steel; B represents semi killed steel: Z indicates calm steel; TZ stands for special sedation steel; calm steel is not marked; Z and TZ are not standard. For example, Q235-AF indicates a class of rimmed steel.
- Q:What is 16a# channel steel?
- A specification for channel steel. Height, width, waist thickness are 160mm, 63mm, 6.5mm,Weight per metre 17.24KG.
- Q:How much is the weight per square metre of channel 10?!
- 10 channel steel, the national standard of rice weight is 10.007, but the production must be worse, the general national standard of about 5%, but also under the difference of more than 15%!
- Q:Steel GB channel and non GB there is no difference?
- Weight difference is obvious, material non-standard is even more difficult to say
- Q:What are the types of channel steels?
- Channel specification, model and theoretical weight table, channel steel is a strip of steel with a cross section. The representation of specifications, such as a*b*c (where a, B, C on behalf of the letters, no other meaning, and the relationship between letters), said waist height is a mm, B mm wide leg channel, channel waist thickness of C mm, or (a/10) # 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 to distinguish, such as 25a#, 25b#, 25c# and so on.
