Metal Ballast
What are Punching’s?
Punching’s: Punching typically refers to the small metal pieces that are produced during the punching process during manufacturing. These pieces are often regularly shaped and can vary in size. Our Punching’s are recycled to minimize waste or sold as Ballast this allows the waste product to reused in various applications, such as filling gaps, adding weight, or serving as raw material for further manufacturing processes.
What is Steel Ballast?
Ballast: In construction, steel ballast refers to a dense material, in this case metal punching’s, Ballast can be made up of other material and it used for applications such as preventing shifting or movement. It is placed beneath railroad tracks or within the hull of a ship to provide stability and weight. Ballast is placed in the deepest part of the hull and is distributed evenly. Adding the correct amount settles the boat in lower water which in turn makes it stable and safer. Our metal ballast can be used in ships to provide moment to resist the lateral forces in the sail. Ballast is essential for maintaining the structural integrity and balance of these structures.
Graepels supply custom Ballast for the marine industry. We supply various weights for an extensive range of vessels, including specialized, commercial, pleasure, naval and cruise ships.
Ballast can also be used in various sectors including renewable energy, engineering, heavy lifting, testing, agricultural and aviation.
Type of Ballast: Several types of ballast materials are available, including gravel, crushed stone, sand, and slag. The choice of ballast type depends on factors such as the intended use (e.g., railroad track, ship ballast), local availability, and project specifications.
Size and Gradation: The size and gradation of the ballast particles are critical factors that influence its effectiveness. The appropriate size and gradation ensure proper compaction, drainage, and stability. Project specifications or industry standards typically dictate the required size and gradation of the ballast.
Quality and Durability: High-quality ballast materials are essential for long-term performance and durability. Factors such as hardness, resistance to abrasion, and ability to withstand environmental conditions (e.g., freezing, and thawing cycles, moisture) should be considered to ensure the ballast maintains its structural integrity over time.

- Good Strength – the three-dimensional shape of the mesh provide strength
- Light (depending on material and thickness this can change) lighter panels and components are easier to work with/handle and reduce transportation fuel and costs.
- Good for anti-slip or anti-skid and wind repellent.
- Low cost due to little or no material waste
- Hight open area
