In china , the cast in channel are implemented the standard :
The surface of the T-bolt shall be flat, without this side, without cracks, and the oblique side of the T-bolt pair of the beveled edge shall be closely fitted with the
oblique side of the steel groove, and the end of the bolt rod of the T-shaped bolt pair shall be processed to position the groove.
In addition to the stainless steel cast-in channel, the surface anti-corrosion treatment of the cast-in channel should be carried out by hot-dip galvanizing process or
other anti-corrosion process with corrosion resistance not lower than hot-dip galvanizing. When using the thermal intrusion galvanizing process, the coating shall comply with:
A) The appearance and thickness of the plating of the cast-in channel shall comply with the relevant provisions of GB/T13912, and the appearance and
thickness of the coating of the T-bolt pair shall comply with the relevant provisions of GB/T5267.3;
B) The corrosion resistance of cast-in channel coating should be tested by neutral salt spray. Red rust should not appear in the cast-in channel
coating for 480h, and red rust should not appear in the T-bolt sub-coating for 240h.
