Steel support

Can withstand greater pressure, tension and bending moments, such as in large building foundation pits, can resist soil pressure and water pressure.

Common type

According to the structure form: steel pipe support, mostly round steel pipe, such as φ400, φ580 and other specifications commonly used in subway foundation pit; H-type steel support, cross-section is "H" shape, often used in large building foundation pit; Steel grid support, composed of steel bars welded into a grid shape, used in tunnels and other underground engineering; Steel arch support, arch, is common in mine roadway and tunnel construction.

According to functional use: including building construction support, such as socket type disc buckle steel pipe support, used in construction, bridge and other fields; Mine roadway support, such as U-shaped steel arch yielding support, trapezoidal yielding metal support, used for mine roadway support; Bridge support, used to support bridge structures, such as piers, abutments, etc.

Application field 

Construction engineering: Used for foundation pit enclosure of high-rise buildings and large commercial buildings, as well as formwork support system to ensure the stability of formwork when concrete is poured.

Underground engineering: In the construction of subway tunnel, mine roadway and urban underground pipe corridor, it is used to prevent surrounding rock collapse and ensure construction safety.

Bridge engineering: as bridge piers, abutments, supports, etc., bear the weight of bridge structure and vehicle load.

Peculiarity

High strength: can withstand greater pressure, tension and bending moments, such as in large building foundation pits, can resist soil pressure and water pressure.

Large stiffness: small deformation can ensure the stability and safety of the supported structure, such as bridge support can maintain the linear shape of the bridge.

Recyclability: most steel supports can be recycled, such as steel pipe supports in subway construction, which reduces project costs and is environmentally friendly.

Easy installation: can be prefabricated in the factory, on-site installation, fast construction speed, such as socket type disc buckle steel pipe support, can improve construction efficiency.
