View Product DetailsThe construction landscape in Los Angeles and the broader Southern California region is undergoing a massive transformation. Rapid transit expansion projects, high-density residential zones, and large-scale industrial warehouses require fast, accurate, and structurally secure concrete building methods. To comply with rigorous seismic regulations—specifically those detailed in the California Building Code (CBC) and Seismic Zone 4 requirements—precast concrete components must be manufactured with precise tolerances.
Under Seismic Design Categories D, E, and F, any structural variation in precast columns, load-bearing walls, or double-T slabs can cause stress concentration points during a seismic event. Traditional formwork systems that rely on drilling, bolting, or tack welding to secure formwork onto casting beds are no longer sufficient. These outdated methods damage the steel surface, leading to irregularities on the finished concrete face.
Magnetic shuttering systems address this challenge. They offer a clean, non-invasive method of securing formwork. High-energy Neodymium magnets deliver targeted downward clamping force to lock side molds in place, maintaining tolerances below 0.5 mm. This helps precast manufacturers consistently meet structural guidelines without warping or displacement during concrete pouring and high-frequency vibration.
California's Green Building Standards Code (CALGreen) and Title 24 Energy Standards place a strong emphasis on reducing carbon emissions and waste in construction. Traditional timber formwork contributes to construction waste, while repetitive welding and grinding on steel beds consumes significant energy and generates localized emissions.
Reusable magnetic shuttering boxes are highly durable, with service lifespans often exceeding 10 years when properly maintained. Adopting magnetic fixing systems allows Southern California precast companies to significantly reduce timber usage and minimize energy waste, aligning their operations with local and state sustainability targets.

Request Price QuoteImplementing magnetic shuttering systems requires an understanding of magnetic force mechanics. The rated holding force (e.g., 2100 kg or 4600 lbs) is measured on clean, flat steel plates. In real-world factory conditions, several factors can affect performance:
The holding force of NdFeB magnets decreases as the air gap between the magnet face and the steel bed increases. Concrete slurry, rust, or surface residues act as physical barriers, creating a gap that can reduce performance. Maintaining a clean casting surface is key to ensuring the system operates at its full rated capacity.
To achieve full magnetic saturation, the steel bed thickness should ideally match the design specifications of the magnet box (typically 8mm to 10mm or thicker). Thinner steel plates may not fully absorb the magnetic flux, which can lower the overall clamping force.
Our shuttering systems feature a robust push-button design that simplifies operation. When pressed down, the magnetic block engages securely with the casting bed. To release, a leverage tool is used to lift the internal button, allowing the formwork to be adjusted or moved without damaging the table surface.

Find answers to common questions about magnetic formwork design, maintenance, and operation.
The choice depends on the height and weight of the concrete elements being cast, as well as the pouring method. 600kg to 900kg magnets are typically used for smaller structural slabs and thin panels. Standard wall panel casting (up to 150mm thickness) generally requires 1300kg to 1800kg units. For heavy panels, high-frequency vibratory tables, or thick columns, 2100kg to 2500kg magnets are recommended to prevent movement under hydraulic pressure.
Yes, our engineering team can customize the height, length, chamfer profile, and attachment adapters to align with your existing casting tables and side rails. We provide technical drawings prior to production to ensure compatibility with your plant setup.
Our shuttering magnets are housed in fully sealed steel casings (available in carbon steel or stainless steel). To ensure reliable performance, it is important to clean the contact surfaces regularly, remove concrete residue promptly, and apply a thin layer of release agent or anti-rust oil.
Standard NdFeB magnetic shuttering systems are rated for operating temperatures up to 80°C (176°F). For steam curing or high-temperature concrete casting environments, we can supply custom high-temperature magnets rated for up to 120°C or 150°C.
