What's the quota for finished H - shaped steel sleeve?
This question is really not easy to answer, the previous set of quotas also encountered this problem
In the installation of H steel, in addition to painting, that is, rust, units are 10m2, there is no security item. Landlord can not really apply: Civil Engineering - metal structural engineering - steel structure - steel wall (or other), and this is my personal opinion, for reference only.
Installation quota, which has a special steel structure production and installation
