Product Description

>>>

The production of solid jacking material is generally made of threaded steel and brand-new round steel Q235, and the production of hollow jacking material is generally made of extruded steel pipe.

In fact, the processing technology we usually say is actually the solid jacking processing technology, which is generally divided into hot rolling and cold rolling. Hot rolling is to pass the steel bar through the plain grain first, then through the high-frequency furnace, and then heat it too much, and then roll it. Cold rolling is to directly roll the steel bar after plain grain.

The jacking models are complete and can support special-shaped customization. The jacking produced by us is sent to all parts of the world, which has made great contributions to local construction projects and has been unanimously recognized by the majority of users.
