30/40kN steel props are high-load telescopic shoring props,engineered for temporary vertical support in construction formwork systems.They provide stable,adjustable support for concrete pouring and structural propping,with a rated working load of 30kN and ultimate safe load of 40kN,balancing strength,adjustability and durability for heavy-duty construction scenarios.
Core Technical Specifications
Load Capacity:Nominal working load 30kN;maximum safe load 40kN(EN1065 Class B/C standard)
Material:High-strength Q235/Q355 carbon steel tubes,ensuring structural rigidity and load-bearing stability
Tube Dimensions(Standard):
Outer tube:Ø48.3mm/Ø60.3mm,wall thickness 2.0–3.0mm
Inner tube:Ø40mm/Ø48mm,wall thickness 2.0–2.5mm
Adjustable Height Range(Common Models):
1.5–2.5m,1.75–3.0m,2.0–3.5m,2.5–4.0m,3.0–5.0m(customizable on request)
Adjustment System:Dual adjustment–coarse adjustment via pin-locked index holes,fine adjustment via threaded nut&handle(≥3 full thread engagement for safety)
End Plates:Square steel top/base plates(150×150mm,thickness≥6mm),with mounting holes for secure connection to formwork and ground
Locking System:Heavy-duty steel locking pin(Ø≥13mm)with anti-lost chain,ensuring secure positioning under full load
Surface Treatment:Hot-dip galvanizing(zinc layer≥80μm),electro-galvanizing,or powder coating(custom colors available)for long-term corrosion resistance
Compliance Standards:EN1065,BS1139,ISO9001,with full load test reports and third-party inspection certificates(SGS/BV)available
Key Features&Advantages
High Load Performance:Optimized tube wall thickness and structural design deliver stable 30kN working load and 40kN maximum load,suitable for heavy concrete slabs,beams and bridge formwork.
Precise&Safe Adjustment:Coarse pin adjustment for quick height setting,fine thread adjustment for accurate leveling;anti-disengagement design prevents inner/outer tube separation during use.
Durable Construction:High-grade carbon steel,full-welded joints,and heavy-duty locking components ensure repeated use and resistance to deformation under heavy load.
Corrosion Resistance:Hot-dip galvanized finish provides long-term rust protection for outdoor and humid construction environments,extending service life.
Easy Operation:Ergonomic adjustment handle for quick height fine-tuning;lightweight design relative to load capacity for easy handling and installation.
Universal Compatibility:Compatible with standard formwork systems,suitable for residential,commercial,industrial,bridge and infrastructure construction projects.
Application Scenarios
Building Construction:Vertical support for concrete slabs,beams,columns,core walls in high-rise,mid-rise and low-rise buildings.
Bridge Engineering:Formwork shoring for bridge decks,piers,box girders and viaducts,meeting heavy-load and large-span support requirements.
Infrastructure&Industrial Projects:Support for subway stations,power plants,factories,water conservancy and municipal construction.
Renovation&Reinforcement:Temporary propping for building renovation,floor addition and structural reinforcement works.
OEM&Customization Options
Custom adjustable height ranges,tube diameters and wall thicknesses to meet project-specific load and space requirements.
Custom surface treatments(galvanizing,powder coating)and brand LOGO printing on tubes and end plates.
Custom top/base plate sizes,locking pin styles and accessory configurations for compatibility with local formwork systems.
Custom packaging,technical documents(drawings,test reports,manuals)and compliance certifications for global market access.
Quality Control
Raw material inspection:Chemical composition and mechanical property testing for Q235/Q355 steel tubes.
In-process monitoring:Welding quality,dimensional accuracy and thread processing control.
Finished product testing:Compressive load test,telescopic function test,locking reliability test to verify 30/40kN load performance.
Full quality traceability with batch records and test certificates for each production run.
