Telescopic Steel Prop is a core temporary load-bearing component for modern construction engineering,specially designed for vertical shoring of concrete formwork,slabs,beams,walls and other structural parts in construction with variable height requirements.Adopting Q235/Q355 high-quality carbon steel as the raw material,the product is manufactured through precision rolling,integral forming and reinforced welding processes,with excellent compressive strength,structural rigidity and impact resistance.Its scientific telescopic double-tube structure realizes flexible height change,which can perfectly adapt to the diverse space height requirements of different construction scenarios,and stably bear the huge vertical load generated during concrete pouring,structural construction and precast component installation,effectively preventing formwork deformation,structural displacement and construction safety hazards,and is an indispensable key accessory for building safe and efficient temporary support systems in various engineering projects.
The product’s core telescopic structure consists of a closely fitted outer tube and inner tube,which slide smoothly without jamming,and is equipped with a multi-gear coarse adjustment+precision fine adjustment dual height adjustment system to meet both rapid height setting and precise positioning needs.Coarse adjustment is achieved through high-strength steel locking pins and evenly distributed multi-position pin holes on the tube body,with a wide adjustable height range covering the common construction needs of low-rise,medium-rise and high-rise engineering,and the gear adjustment is firm and fast,greatly improving the on-site erection efficiency.Fine adjustment is completed by the precision threaded screw jack and humanized rotating handle at the top of the prop,which can realize micro-calibration of the support height,ensure the top plate is perfectly attached to the supported structural surface,realize uniform load distribution,and avoid local stress concentration that may cause structural damage or support instability.
To further enhance the overall support stability and load-bearing safety,the top and bottom of the Telescopic Steel Prop are equipped with thickened and enlarged reinforced steel top plates and base plates.The enlarged contact area effectively disperses the vertical load to the ground and the supported structure,preventing the prop from sinking into soft ground or causing local pressure damage to the structural surface due to excessive stress;the reinforced plate structure improves the bearing capacity of the end parts,avoiding deformation or damage under long-term heavy load use.The product is also configured with a complete multi-layer locking system,including anti-slip steel pins,cotter pins and threaded locking collars,which can firmly lock the adjusted telescopic position of the inner tube,completely preventing accidental sliding of the inner tube during construction under dynamic loads such as concrete pouring and construction vibration,and ensuring the long-term stability of the support system.
For different construction environments and service life requirements,Telescopic Steel Prop provides a variety of professional anti-corrosion surface treatment options,including electro-galvanizing,hot-dip galvanizing and powder coating.Hot-dip galvanizing forms a dense,uniform and wear-resistant zinc layer with a thickness of not less than 80μm on the product surface,with excellent rust and corrosion resistance,suitable for long-term use in harsh outdoor environments such as open air,humid areas,coastal salt spray zones and industrial construction sites;electro-galvanizing and powder coating have good anti-corrosion performance and a neat,smooth appearance,suitable for indoor dry construction scenarios such as interior decoration,indoor formwork support and small-scale structural reinforcement.All surface treatment processes are standardized and mature,with strong coating adhesion,not easy to fall off during transportation,stacking and on-site use,effectively extending the service life of the product and ensuring stable performance during repeated use.
All models of Telescopic Steel Prop are designed and manufactured in strict accordance with international construction industry standards such as EN1065,BS1139 and ISO,and each batch of products has undergone comprehensive performance tests including compressive strength,static load-bearing capacity,impact resistance and thread wear resistance.The product has the characteristics of humanized operation,convenient transportation and strong practicality:the lightweight structural design and rotating handle make height adjustment,installation and dismantling simple and fast,which can be completed with basic on-site tools without professional operation skills;the telescopic structure allows the product to be retracted to the minimum length for stacking and storage,greatly saving transportation and on-site storage space;the whole prop has a compact structure and strong interchangeability of accessories,facilitating on-site material matching,replacement and maintenance.It is widely used in various construction projects around the world,and is the preferred height-adjustable vertical support component for engineering construction with diverse height requirements and high load-bearing safety standards.
