Commercial Applications:
1) Internal support system: In deep foundation pits for subways, super high-rises, and large-scale complexes, steel props are used in conjunction with retaining piles to control excavation deformation
2) Template and Temporary Support: In the construction of beams, slabs, high formwork, and large-span structures, provide vertical and horizontal support to ensure the stability of the template system and the quality of concrete forming
3) Application scope: the steel props are widely used for support for subways and tunnels, bridge engineering, highway and railway engineering, and mining tunnels
Steps for adjusting the use of steel supports:
1. Preparation work: Check whether the steel support is bent, cracked, the thread is intact, and the adjustment is smooth.
2. Install the base: Place the base on the ground or floor, level and stabilize it. If the ground is soft, a cushion plate should be added to prevent sinking.
3. Preliminary height adjustment: Pull out the inner tube and adjust it to a height close to the intended use. Insert the safety pin to prevent sudden slipping.
4. Place the top support: Place the top support on top and press it against the bottom of the beam, slab, or formwork to ensure that the top support is centered, firm, and not skewed.
5. Fine leveling: Rotate the adjusting nut, slowly raise the support, and push the template to the design elevation. Tighten but not deform due to excessive force.
6. Reinforcement and inspection: if necessary, add slant support and pull rod to prevent side fall, and check whether all pins and nuts are locked.
7. Removal steps: first remove the surrounding formwork, slant support, etc. Loosen the adjusting nut and slowly descend. Remove the top support, pull out the safety pin, and retract the inner tube. Handle with care and store by category.

FAQ:
1) What are adjustable steel props mainly used for?
They are mainly used for vertical supporting of formwork in building construction, floor slab and beam pouring, tunnel support, and temporary supporting of engineering structures.
2) How to adjust the length of steel shoring?
Rotate the adjusting nut to extend or shorten the inner and outer tubes. Insert the safety pin and lock the nut after reaching the required height.
3) What is the load capacity of steel prop?
The normal load capacity is 20kN–50kN, depending on the pipe diameter, wall thickness and product model.
4) What are the surface treatment for the steel shoring props?
There are pre-galvanized, electro-gavanied, hot dip galvanized, spray coating
