Two floors of shops, exterior wall hanging marble, I would like to ask the general keel, channel, angle steel with what kind of specifications? Is the angle iron L30*3 channel 6.3 OK? Do keel labour contractor, how much is the market price? The older generation with the experience helped! Thank you
This is calculated from the load analysis.
To see more large stonesCommonly used are 8# channel steel and 4# angle steel,You might be a little small,The key is to look at the specifications and weight of the stone.
Conventional channel steel has 10#. 8#. 6.3 of the connection length, spacing, and various loads are very large. The angle iron is usually 5#4mm or 5mm and has to be calculated. Generally, it is accessible.
