Steel Prop

Steel Prop,a vital vertical load-bearing component in construction,is designed to support structures temporarily or semi-permanently during concrete pouring,formwork installation,or maintenance.It transfers vertical loads(concrete self-weight,construction materials,live loads)from upper structures to the ground,ensuring stability and preventing deformation.Widely used in residential,commercial,and infrastructure projects,it outperforms wooden props with higher strength,durability,and reusability.

Structurally,it features a robust design:the main body is made of Q235 or Q355 carbon steel(yield strength≥235MPa),often in seamless tube form(Φ48-Φ89mm diameter,3-5mm wall thickness)for rigidity.Adjustable models include an inner telescopic tube with adjustment holes and a locking pin/bolt for height setting(range 1.2-4.8m).A top bearing plate(100×100-150×150mm,≥5mm thick)distributes loads evenly,while a bottom base plate(≥150mm,≥5mm thick)prevents ground sinking.

Classified by adjustability:Fixed steel props(fixed length,for standard-height scenarios)and adjustable steel props(telescopic,for variable heights).By load capacity:Light-duty(≤15kN,for thin slabs),medium-duty(15-30kN,for standard floors/beams),and heavy-duty(≥30kN,for large-span structures).

Key applications:Supporting concrete formwork for floors,beams,and columns;bracing prefabricated components during installation;reinforcing scaffolds in high-rise projects.

Safety guidelines:Select props matching calculated loads(never overload);install vertically(deviation≤1°);secure locks tightly;inspect for cracks,bends,or rust before use(discard damaged units);avoid lateral loads to prevent buckling.Its reliability makes it indispensable for safe,efficient construction.
