Your Well-made Shoring Props
Shoring Props are used in the construction industry for temporary support of ceilings, walls and trenches (shoring). To install, first stand the shoring prop into the work area, adjust the height so that it almost fills the gap, and insert the pins to lock the inner and outer shoring prop tubes. Any remaining gap is then closed with screws until it is securely fastened to the support area.
Shoring props are mostly used for shoring: temporary support during building repair or alteration work, rather than scaffolding: an access platform for workers. Typical use is to support existing horizontal beams for table moldings.
You can have an inner tube in diameter of 40mm and 48mm for APAC’s shoring prop as well. When the inner tube diameter is 40mm/48mm, the outer tube will be 48mm/56mm.
APAC’s shoring prop jacks are widely used in scaffolding and concrete formwork support in Europe. The height of the props is adjustable, you can ask APAC to design and customize the height according to your slab /floor height.
The components of the shoring prop include prop outer tube, inner tube, G pins/ straight pins, top and bottom steel plates, prop nuts and handles etc.
APAC shoring prop can be used for multiple applications, such as the construction of slabs, pier caps, tunnel vaults, bridge decks, or any other concrete structure that requires the use of falsework.
Choose your material and surface treatment
We usually typically use S235 steel or S345 steel, both of which are commonly used in the industry. S345 steel will make the shoring prop has a better loading rating, we recommend you use S345 steel.
APAC provides OEM service for the shoring prop, the surface treatment you can find here are hot-dipped galvanized, galvanized steel, painting, and powder coated.
APAC is able to offer you shoring prop based on the weight load requirements. You can not only find the normal light-duty props. Other medium-duty and heavy-duty steel acrow props are available too.
Shoring Prop | The Ultimate FAQ Guide
Shoring Props are an integral part of construction. The modern shoring props offer high flexibility and versatile features. These units have completely simplified many formwork and framework complexities in today’s construction sites.
Are you interested in shoring Props?
Read through this FAQ guide to get the answer to all your basic queries on shoring props.
Shoring props are temporary structural elements. These are basically cylindrical-shaped components with a metallic hollow body. The typical shoring props have two additional horizontal plates at two ends.
At various construction stages, you need to temporarily support different structural members. You can provide rigid support to these members with the shoring props. Once the members are stable, you can move them back for other functions.
Figure 1 – Typical Shoring Props
The shoring props are used in various stages of construction. You can use them for:
You can quickly mount shoring props to offer temporary support to different components. Once you are done, you can easily remove the shoring props.
Heavy load-bearing components
The shoring props are made of highly durable metals, which make them ideal load-bearing components. So, you can use shoring props to support very heavy structural members or other elements.
Beam, slab, and column formwork components
In concrete constructions, the newly casted concrete takes some time to gain their target strength. During this time, you need to provide rigid support to the formwork containing these members.
Using the shoring props, you can easily provide vertical support to beam and slab members. For the column sections, you need to provide horizontal support. Install the shoring props at an inclined angle to support them horizontally.
Different manufacturers offer shoring props with many adaptable features. Using a few additional pieces, you can use them for scaffolding solutions to assemble shoring towers, guard rails, etc.

The shoring props are also suitable to carry a limited amount of load on the lateral side. To set up temporary working platforms, use suitable pieces to adjust them horizontally as platform beam. Place the top platform member on the platform beam to distribute the load.
- Use shoring props with a load-bearing capacity equal to or exceeding load specified by standards or the structural engineer.
- Take the help of a professional or calculate following the standards, the specifications, and the number of required shoring props.
- Mark the positions where you want to set up the shoring props.Adjust and place the base plate in the marked position. The area must be a rigid, load-bearing surface.

- Release the support pins.
- Pull the extension tube towards.
- Attach the top plate to the target position.
- Insert the support pins.
- Tighten the screw to create balanced pressure until the shoring prop starts to take the load.
Shoring props are accepted as standard structural elements worldwide. With proven safety features and versatile application scopes, the shoring props are now an integral part of the construction sector.
But to ensure safety while using the shoring props, you have to follow the proper guidelines. You have to follow the national and local standards while using them. The standards are set with sufficient safety factors to ensure they never fail to provide the ultimate safety.
You can adjust the shoring jack posts to adjust with shorter or longer lumber shores. Most manufacturers recommend a maximum adjustment range in shoring jack posts within 3-4 inches.

To adjust, you can turn the adjustment screw clockwise for longer posts and anti-clockwise for shorter posts.
Aluminum is a lightweight material. So, aluminum shoring props are extremely popular due to their flexible and easy handling opportunities. They are also highly durable. Their durability advantages are:
- Aluminum is a naturally corrosion-resistant material. So, aluminum shoring props are durable due to their long lifespan.
- Shoring props with aluminum alloys can be engineered to be as strong as steel shoring props.
- Aluminum absorbs impacts elastically, for example, when your shoring prop falls over.
Aluminum shoring props require less maintenance.
Similar to the size specification of shoring props, you can also see a range with two values for the load-bearing capacity of shoring props. The smaller value in the range specifies the load capacity at extended conditions. The larger value specifies the load capacity at closed conditions.
The load-bearing capacity of normal shoring props can be from 8 KN to 45 KN. For heavier series, the range can be from 36 KN to 80 KN. Some manufacturers also manufacture shoring props capable of 200 KN load capacity.
You can find the load capacity mentioned in other units like Kip or lb.
The advantages of galvanized shoring props are:
- Requires less maintenance
- High tensile strength
- Strong toughness rating
- Corrosion and weathering resistant
- More durable
- Suitable for industrial applications
When you see the size specification of shoring props, you can always see a range with two values. The smaller value in the range specifies the minimum length. The larger value specifies the highest extendable length.
Most manufacturers offer shoring props in five standard sizes with minor differences. These are:
- 3’-6” to 6’-0”
- 5’-9” to 10’-3”
- 6′-6” to 11′-0″
- 8′-6″ to 13′-0″
- 10′-6″ to 16’-0”
Based on application scope, manufacturers also offer other sizes of shoring props.
You can remove the shoring props once the structural members are able to support their self-weight or reach their full strength.
You can follow this table to the standard timing of shoring props removal:
Description of a structural member
Removal of shoring props to slabs
(a) For slabs spanning up to 4.5 m
(b) For slabs spanning over 4.5 m
Removal of shoring props to beams and arches
(a) Spanning up to 6.0 m
(b) Spanning over 6.0 m
Walls, columns, and vertical sides of beams
