Commonly used construction props include:

1. Adjustable Steel Props:
   • Advantages:
     • Adjustable height for versatility.
     • Strong and durable, suitable for supporting heavy loads.
     • Easy to install and dismantle.
   • Disadvantages:
     • Can be heavy to transport.
     • Limited to vertical support only.
2. Acrow Props:
   • Advantages:
     • Adjustable height with a screw mechanism.
     • Lightweight and portable.
     • Can be used horizontally or vertically.
   • Disadvantages:
     • May not support as heavy loads as steel props.
     • Requires periodic maintenance of the screw mechanism.
3. Aluminum Props:
   • Advantages:
     • Lightweight and easy to handle.
     • Corrosion-resistant.
     • Adjustable height for versatility.
   • Disadvantages:
     • Not as strong as steel props, limiting load-bearing capacity.
     • More expensive than steel props.
4. Telescopic Props:
   • Advantages:
     • Adjustable height with a telescopic design.
     • Compact and space-saving for storage and transport.
     • Suitable for supporting various ceiling heights.
   • Disadvantages:
     • May have a lower load-bearing capacity compared to traditional steel props.
     • Can be more complex to adjust and set up.
5. Heavy-Duty Props:
   • Advantages:
     • Designed for supporting exceptionally heavy loads.
     • Sturdy and durable construction.
     • Suitable for use in demanding construction environments.
   • Disadvantages:
     • Typically heavier and bulkier than standard props.
     • May require specialized equipment for handling and installation.
6. Light-Duty Props:
   • Advantages:
     • Lightweight and easy to handle.
     • Suitable for lighter construction tasks.
     • Lower cost compared to heavy-duty props.
   • Disadvantages:
     • Limited load-bearing capacity.
     • May not be suitable for supporting heavy loads or larger structures.

Each type of construction prop has its own set of advantages and disadvantages, which should be carefully considered based on the specific requirements and constraints of the construction project. Factors such as load-bearing capacity, adjustability, weight, durability, and cost should be taken into account when selecting the most appropriate props for the job.
