Classified by structural form
Herringbone/cross shaped support: a triangular stable structure formed by inclined arrangement, commonly found in subway stations and bridge foundation pits.
Portal support: composed of a portal frame, modular design, high installation efficiency, suitable for indoor or decorative projects.
Suspended support: Suspended from the outside of the building structure to save ground space, commonly used in the construction of high-rise building facades.
Attachment type lifting support: It can be lifted and lowered as a whole through an electric device, synchronously lifting with the height of the building, and is suitable for super high-rise buildings.
according to the materials
Steel pipe support: With circular or rectangular steel pipes as the main body, it has strong bearing capacity and flexible installation, and is the mainstream choice for foundation pit support.
Steel support: using standard steel such as H-beams and I-beams, suitable for scenarios with high strength and stiffness requirements (such as bridge piers and large-span buildings).
Steel grid support: welded into a grid shape by longitudinal and transverse steel components, commonly used for initial tunnel support, providing flexible support.
