Surface Technology

1. Hot Dip Galvanized: The metal parts are cleaned and treated, then dipped in molten zinc at about 850°F (about 455°C). After cooling, a strong zinc coating is formed. The zinc coating formed provides excellent corrosion protection and effectively prevents metal surfaces from atmospheric, water and chemical attack, extending the life of metal products.

2. Pre-Galvanised: Pre-galvanising is a process by which a layer of zinc is applied to a coil or sheet of metal prior to the manufacture of the metal product. Pre-galvanising is done before the metal is processed into the final product. The main advantage of pre-galvanising is that the coated zinc layer provides good corrosion protection even if the metal is machined, bent or cut during the manufacturing process.

3. Powder Coated: Powder coating process is a coating technology, through the powder coating evenly sprayed on the surface of the items, and cured at high temperature to form a solid coating, with the advantages of uniformity, corrosion resistance, environmental protection and diversity. And it is possible to change the colour of the coating, such as black, blue, red, and so on.


Load Bearing


1. Heavy Duty: Heavy-duty steel prop are typically made from high-strength steel materials and are designed to withstand large amounts of pressure, weight, or other external forces. Different types of props have different load-bearing capacities, please contact us for details.

2. Light Duty: light duty steel prop are lightweight and relatively small in size, shape and thickness. They are used in situations where structural requirements are not high and a lighter support structure is required, such as non-load-bearing walls in residential buildings and commercial buildings.



      The length of the steel prop can be adjusted. According to different building heights, the heights that steel prop of different sizes can reach are also different. For example, they can be adjusted to 4 meters, 5 meters, 6 meters, etc. But we also need to consider their load-bearing capacity. If you don't know which size steel acrow prop to choose, please contact us and we will choose the most suitable product for you based on your project.



AJ Building’s Customer Project Experience

      Adjustable floor props, with their versatility, are essential in various construction scenarios. They are commonly used to support formwork during concrete casting, provide temporary support during underpinning or shoring, and offer stability for horizontal elements like slabs and beams.

A Complete Guide to Steel Acrow Prop

Steel Acrow Prop Is What:

      Steel props are a kind of prop systems that are used in construction projects and that consists primarily of steel, providing support and stability. It belongs to a series of scaffolding. They are typically employed for the temporary support of structures in buildings, bridges, tower cranes as well as other constructions to ensure safety and steadiness during construction. They can then be knocked down once construction work is completed on the building.


Other scaffolding systems used worldwide:


What Makes Up The Acrow Prop:

      The Acrow prop is comprised of two steel tubes, one tube inside the other, and joined together by a sliding arrangement. Below are the sections:Steel outer tube: It has a welded base plate at its bottom for stability assurance.

  • Steel inner tube: Has top plate wrapping around and going down over threads.
  • Strut Collar: Located on the outer tube and helps adjust the height of the strut.
  • Support Pin: This is a steel pin that is inserted into the hole in the inner tube to lock it at the desired height.


Different Types Of Steel Supports:

  • Vertical Support
  • Diagonal Support

Surface Technology

      Galvanized steel props are available in two solutions, pre-galvanized and hot-dip galvanized (HDG). Pre-galvanizing is the process of dipping unfinished steel into molten zinc to form a zinc-iron alloy coating.

      The thickness of the zinc layer in pre-galvanizing is usually between 20-60 microns. Electro-galvanizing is the process of dipping clean steel into an electrolytic solution containing zinc ions and depositing a layer of pure zinc metal on the surface of the steel using an electric current. The thickness of the zinc layer is usually thinner than pre-galvanized, typically between 5-25 microns. Hot-dip galvanized (HDG) steel supports have a longer service life than electro-galvanized. Steel support props can be made from HDG steel pipe or black steel pipe.

      AJ Building has high precision spraying equipment, which can precisely control the thickness and range of spraying, so that powder coated steel support props have a smooth and bright surface, rich in color, and look very beautiful. Unlike the traditional painting process, powder coating is more environmentally friendly and the steel props have a longer service life.


How To Use An Adjustable Steel Props

  1. According to the design requirements, install the main structure to support the product, such as steel pipes, support frames, etc.
  2. Use appropriate connectors to secure the support product to the ground or building, and adjust the height and angle of the support product to ensure stability and level , and lock it.
  3. As needed, install auxiliary support structures such as diagonal braces and horizontal braces to increase overall stability and load-bearing capacity.


Pay Attention:



Calculating the Dosage

      How many Acrow props are there in one meter? Most often professional engineers will go with one Acrow Prop per meter (this is a common rule), however, this may not be appropriate for every job. Ensure that props are evenly spaced to give an even load.

      Do you need to know the amount of steel support required for your entire project? Please contact us and we will calculate the quantity of products for you based on your project area, etc.

Acrow Props Serve Various Purposes, Including:

  • Providing direct support during building repair, alteration, or renovation projects.
  • Facilitating the replacement of openings such as doors, windows, or archways.
  • Creating new entrances, windows, or archways within existing walls.
  • Acting as framework support for walls, stairs, and columns.
  • Supporting lintels, beams, canopies, and concrete structures.
  • Offering essential support for trench walls during ground excavations.




Acrow Prop Storage Conditions

  1.  First, in a dry environment, building materials should be stored to prevent moisture absorption, which can cause rust, corrosion, and degradation of materials. Avoid storing them in places prone to leaks or high humidity.
  2. Second, covered storage, provides a covered storage area, such as a warehouse or shed, to protect materials from direct sunlight, rain, and other weather elements. This helps prevent damage and prolongs the life of the material.
  3. Third, ventilation, make sure the storage area is well-ventilated to allow for air circulation. Adequate ventilation helps prevent moisture buildup and condensation, reducing the risk of corrosion and mold growth.
  4. Fourth, separate and organize, and store different types of building materials separately and keep them tidy. This facilitates easy access, minimizes the risk of damage, and simplifies inventory management. Use racks, racks, or trays to keep materials high and off the ground.
  5.  Fifth, to protect against pollutants, avoid storing construction materials near substances that could damage them, such as chemicals, solvents, or other corrosive materials. Also, keep them away from areas prone to excessive dust, dirt, or debris accumulation.
  6. Sixth, weight considerations, when stacking or storing heavy construction materials, please consider the load-bearing capacity of the storage area. Make sure the storage structure can support the weight without risk of collapse or damage.
  7. Seventh, security measures, implement appropriate security measures to protect stored materials from theft or unauthorized access. This could include fencing, locked gates, security cameras or sirens.


      We have a case, in a coastal city, our customer stores scaffolding outdoors, because the salt particles in the coastal air contain chloride ions, which are very corrosive to steel. When these salt particles come into contact with the steel surface, they react with the moisture and oxygen in the air, causing the scaffolding to corrode and become unusable.


The storage of scaffolding in coastal cities to prevent corrosion can mainly be done in the following three points:

  • First, apply a protective coating, using a corrosion-resistant coating such as paint, epoxy or galvanizing on the steel to create a barrier against salt particles and moisture.
  • Second, regular cleaning, regularly clean the steel surface to remove accumulated salt and other contaminants that can cause corrosion.
  • Third, monitoring and maintenance, regularly check whether the stored steel has any signs of corrosion or damage, and solve the problems found in time.


By implementing these measures, you can help minimize the adhesion of salt particles and reduce the risk of accelerated corrosion of steel stored close to the sea in coastal environments.
