Features:
Suitable for the connection between beams and columns, including steel plate connections and embedded connections in some special structures
There are many types of weldable steel bar connections, including rotating structures of columns welded to steel plates, embedded in floors, and some special parts of the design. The weldable types are very flexible and can be customized according to the different application locations and requirements of customers. The following are common types：
Anchor type：The entire bolt is fixed to the plate, and the sleeve can be connected in both directions
The one-way connection type is commonly used in embedded and steel plate welding. The sleeve is designed for one-way connection, and the other end is welded fixed mode.
Weldable bidirectional mode, this sleeve is a multifunctional and multi-purpose model in weldable connections. It is very flexible. It can be connected to the base plate as a pre-embedded system, can be connected to the steel column as an extension system, and can also be used as a bidirectional anchor connection. It is a weldable model that is more popular among customers.
The fixed set of weldable sleeve connections are directly welded to the steel plate. There are two modes at both ends of the sleeve, one is forward and the other is backward. The forward mode is mostly used in the docking of two concrete slabs, and the forward mode is mostly used in concrete pre-embedded.
