Scaffolding and aluminum formwork are widely used reusable materials in construction. After use, scaffolding becomes coated with concrete residue, rust, and welding slag, while aluminum formwork surfaces retain concrete, release agent, and cement paste. If these residues are not thoroughly removed, they affect the casting quality and formwork service life for the next use. Shot blasting is an efficient solution for scaffolding and aluminum formwork cleaning.


Application Background

Scaffolding and aluminum formwork are repeatedly used on construction sites, with each use causing concrete residue, mortar, rust, and release agent to adhere to the surface. Traditional manual cleaning methods are inefficient, produce poor results, and tend to damage materials. Shot blasting quickly and uniformly removes various residues, restoring the material surface and extending service life.


Core Functions of Shot Blasting

Removal of Concrete Residue

Concrete and mortar adhere to scaffolding and aluminum formwork surfaces after use. Shot blasting uses high-speed abrasive impact to strip concrete residue from the surface, exposing the clean base material.


Removal of Rust

Scaffolding rusts during storage, affecting safety and service life. Shot blasting effectively removes rust, restoring the steel surface condition.


Removal of Release Agent Residue

Aluminum formwork requires release agent application before each use, leaving residue and cement paste after use. Shot blasting thoroughly removes these residues, preparing the formwork for the next use.


Improvement of Surface Quality

After shot blasting, the surface develops a uniform roughness, facilitating even release agent application and improving concrete casting quality.

Process Results

After shot blasting, scaffolding and aluminum formwork surfaces are free of concrete residue, rust, and release agent residue, displaying a uniform metallic appearance. The surface roughness is moderate, facilitating even release agent application and improving concrete casting quality and formwork service life.


Zhiling Machinery Advantages

Zhiling Machinery provides customized shot blasting solutions for the construction reusable materials industry. Based on material type and production requirements, we recommend appropriate equipment types and configurations. Mesh belt shot blasting machines offer advantages in aluminum formwork cleaning, including gentle processing, no deformation, and high efficiency. We have supplied equipment to numerous construction reusable material rental and production enterprises.


Equipment Selection for Different Scaffolding and Formwork Applications

Scaffolding systems and aluminum formwork products vary significantly in size, shape, and production volume. Selecting the appropriate shot blasting equipment helps improve cleaning efficiency, reduce labor costs, and extend the service life of reusable construction materials.

  • For aluminum formwork panels, an aluminum formwork shot blasting machine provides efficient removal of concrete residue, cement paste, and release agent buildup while protecting the dimensional accuracy of the panels. This solution is widely used by aluminum formwork manufacturers and rental companies that require consistent cleaning quality and high throughput.

  • For scaffolding pipes, steel planks, cross braces, and other long structural components, a pass-through shot blasting machine enables continuous processing with minimal manual handling. Workpieces move through the blasting chamber automatically, making this solution ideal for large-scale refurbishment and rental operations.

  • For scaffolding frames, couplers, brackets, and irregularly shaped construction components, a single hook shot blasting machine offers greater flexibility. The suspended workpieces can be exposed to abrasive flow from multiple directions, ensuring uniform cleaning of complex surfaces and hard-to-reach areas.

The most suitable solution depends on workpiece dimensions, production volume, cleaning requirements, and the desired level of automation. Zhiling Machinery can customize equipment configurations for formwork manufacturers, scaffolding rental companies, and construction material processing facilities.
