Bolt connection: Choose the right bolt specifications and materials to ensure the connection strength. Use washers and anti-loosening devices (such as spring washers, locking nuts) to prevent the bolts from loosening. Check the tightness of the bolts regularly and re-tighten them when necessary.

Embedded fixing: The channel steel is pre-fixed in the formwork before pouring the concrete. After the concrete solidifies, the channel steel is firmly embedded in it.
