Building with steel or steel plate?
A channel is more reasonable, the steel is solid, itself is very heavy, do not use solid steel structure, are used in pipe, angle steel, I-beam, etc. are all hollow
It is recommended to use channel No. 12, and the span of three meters is not big, so the problem of vibration will not occur! Square steel tubes are not recommended for load-bearing structures. I'm from the steel installation department.It is suggested that the upper channel, the red plate, and the wood. It's more comfortable to use.
Recommended use of channel ten, three meters span is not large, there will be no vibration problems! Do not use the bearing structure of square steel tube, the solid steel with the specifications of the cost is too high and the bending strength is hollow, not recommended.
