Shoring post
Application Scenarios: Widely used in highway/railway tunnels, mine roadways, and underground cavern excavation projects, especially suitable for support operations under soft surrounding rock, high in-situ stress, and complex geological conditions.
Material and Craftsmanship: Made of Q235 steel with high strength and good toughness; multiple surface treatments like galvanizing and painting for corrosion resistance and long service life.
Shoring Post: Adjustable Q235 Steel Prop for Slab and Beam Formwork, 1.7 m to 5 m
The shoring post, a telescopic prop that bears the vertical load of floor slabs and beams during concrete pouring, is one of the Q235 steel adjustable props manufactured by Hebei Xinjiuyi Construction Technology Co., Ltd. Available in Heavy Duty and Light Duty versions. Inner tube diameters are 48 mm and 40 mm; outer tube sizes are 60 mm, 48 mm and 56 mm; wall thickness from 1.6 mm to 4.0 mm. Length series are available in four length series ranging from 1.7m to 5m. Custom size, style and colour are available from Xinjiuyi.
Product Overview
Adjustable steel props are often called Acrow props or telescopic steel shoring. Each product is made up of four components: inner tube, outside tube, nut and handle and G-pin. The sliding mechanism and threaded collar allow for precision incremental height adjustment.
Steel props are an alternative to wood supports and may be utilised from project to project.

Finish Options
Select the finish depending on where the props are:
- Pre-galvanised: a basic choice for most use.
- Painting: a low-cost coating for inside, climate-controlled locations.
- Hot dip galvanising: thicker zinc for outdoor exposure.
- Powder Coating: A Baked On Finish.
Design Details
The snap-type modular connection eliminates the need for field welding, allowing personnel to swiftly install and disassemble the props. Its uniform shape also means little site occupancy.
The shoring post has a U-head or fork head which cradles principal beams or joists and prevents lateral sliding. The welded base plate distributes the axial stress and acts as the anchor for the levelling jacks.
Heavy Duty and Light Duty Types
They are different in tube size and wall thickness. Light Duty props are used for thinner slabs and Heavy Duty props for massive reinforced concrete beams with varying heights.
Load capacity decreases as the inner tube is extended. Refer to the load table for your particular model and work to the safe working load, not the ultimate load.
Applications
In building construction, shoring post is used to support slab and beam formwork. Steel props may assist speed up floor cycles in high rise residential buildings.
Props may also be used for other temporary support functions, such as horizontal bracing, with the right end fittings. In this scenario, the first thing a structural engineer needs do is compute the buckling force.
What to Check Before You Order?
Use this checklist when sourcing adjustable steel props:
- Material: ask for paperwork proving the grade of the steel.
- Load Data: Ask for the load chart for your model showing ultimate load and safe operating load at various extensions.
- Dimensions: check tube diameters, wall thickness, length series and thread fit.
- Finish: Confirm the coating type that is appropriate for your site circumstances.
- Standards: Find out what standard your market demands and ask for the relevant paperwork.
Care and Maintenance
For painted props, retouch scratches promptly to prevent rust. For galvanized props, keep the threads free of concrete debris and apply a light film of oil.
Customization and Project Support
Xinjiuyi can make props according to your designs, measurements and application, you can pick the style and colour. The facility is located in Xian County Development Zone in Cangzhou, and implements standardised manufacturing with quality control.
The team provides design help, solution planning, on-site installation instruction and after-sales support. You may add hoist safety gates, floor edge protection and ladder cages to the same order.
Packaging
Props ship in bundles for stable transport and simple stacking at the site.
FAQ
Q: What does a U-head or fork head do?
A: It carries joists or beams and keeps them from rolling sideways which is good for formwork support.
Q: How can you change the height of a loaded product?
A: When under stress, do not turn the threaded collar. First reduce pressure with a secondary support or pry bar to safeguard the threads and the operator.
Q: Which finish to use for diverse environments?
A: If the location is outside or sea, props should be galvanised or powder coated to withstand corrosion. Props are painted for indoor, temperature controlled venues.
Q: What happens if you go beyond the safe working load?
A: Overloading may lead to the steel tubes deforming and hence diminish the safety margin for future usage. Work within the load chart for your model, at all times noting the safe working load.
