Architectural screw is a component commonly used in construction to support and adjust height. As a hollow screw, it is also a kind of architectural screw. It also plays a role in height adjustment and support. Beautiful, durable, and as an environmentally friendly building, the screw is essential.
Usually the screw rod is cut and welded by the ordinary thread rolling machine, and the hollow screw rod is an exception. When the hollow screw rod is processed by steel pipe, if the ordinary thread rolling machine is used for processing, it will It is easy to deform the steel pipe, so the hollow screw can only be produced with a three-axis thread rolling machine. Although both are scaffolding accessories, in the production process, it is necessary to distinguish between solid screw and hollow screw.
In terms of processing, since the hollow screw rod is galvanized or painted, the plating material cannot flow out compared to the solid screw rod. Therefore, if surface processing is required, it is recommended to leave holes on the support to facilitate the flow of the plating material.
