Q:You design expert asked: do barrier 5 meters, how long the channel to bear?
Through my own experience, you need 10 cm or 12 cm Fang Gang (Pihou requirements GB) as the main girder, the main girder can not be separated, to ensure his strength, if conditions permit can be supported by channel 10 cm at the bottom, so it is very strong, and the spacing between the main girder beams can not exceed 400MM.
Q:Do galvanized steel channels need anti rust treatment?
Just like roadside poles, most of them are hot-dip galvanized, and they also have to be passivated. Of course, if you apply the paint again, the rust proof effect will be better.

If the cost per meter, of course, is light and cheap.The specific gap, you can also refer to the hardware manual, the two are compared. Because of the tonnage, the prices are almost the same.

Not 20A. It should be 20A. The letters in the back of the numbers are different in meaning. The letters behind the channel must be lowercase (waist thickness is different).20 represents section height 200mm of channel steel, 200*73*7.0 theoretical weight 22.637
