Magnetic Urethane Chamfer
Composition & Key Properties
Magnetic Urethane Chamfers are engineered using high-performance urethane elastomers combined with NdFeB (neodymium) magnets. This design merges advanced material properties with magnetic adhesion capabilities:
· Durability: Urethane ensures high wear resistance (>200% longer lifespan than rubber) and impact absorption, ideal for construction machinery or high-traffic flooring.
· Magnetic Performance: Embedded NdFeB magnets provide strong adhesion (15–25 N/cm²) to steel, galvanized metal, or iron-based formwork.
· Shore Hardness Options: Two primary grades are standardized:
o 60 Shore A: Offers flexibility for curved surfaces or delicate chamfering (e.g., decorative concrete).
o 90 Shore A: High rigidity for heavy industrial use (e.g., ports, airport runways).
· Temperature Stability: Operates from -40°C to 120°C without losing elasticity or magnetic strength (if coated magnets are used).
· Chemical Resistance: Resists oils, solvents, and UV degradation, suitable for outdoor or chemical-exposed environments.
Construction Features
1. Integrated Design: Magnets are fully encapsulated within urethane to prevent corrosion and mechanical damage.
2. Chamfer Dimensions:
o Width: Customizable 50–200 mm (5–20 cm), accommodating edge profiles from fine bevels to broad slopes.
o Length: Standard 1–6 m with modular connectors for seamless curves (e.g., circular columns).
3. Surface Treatments: Textured or smooth urethane surfaces minimize concrete sticking during demolding.
Applications
· Modern Architecture:
o Edge protection for polished concrete floors, terrazzo, or exposed aggregate.
o Rounded edge formation in precast panels (e.g., staircases, facade elements).
· Industrial Infrastructure:
o Heavy-duty chamfering for steel-reinforced concrete in bridges, tunnels, or ports.
o Used with tilt-up wall systems to prevent corner spalling.
· Specialized Use Cases:
o Magnetic adhesion simplifies alignment in 3D-printed concrete mold setups.
o Reusable in modular construction projects (e.g., prefabricated buildings).
Functional Advantages
1. Rapid Installation: Eliminates clamps/screws—3x faster than traditional methods.
2. Repeatable Precision: ≤1 mm edge deviation over 200+ cycles.
3. Cost Efficiency: Reduces labor and material waste by 40% compared to single-use PVC.
4. Sustainability: Recyclable urethane and reusable design align with LEED/GREEN certification standards.

Optimized Usage Guidelines
1. Substrate Prep: Ensure metal surfaces are clean, dry, and free of rust or debris.
2. Chamfer Size Selection:
o 50–100 mm: Thin edges (e.g., wall joints, decorative tiles).
o 100–200 mm: Structural edges (e.g., warehouse floors, vehicle ramps).
3. Hardness Pairing:
o 60 Shore A: Flexible for lifted edges or temporary formwork.
o 90 Shore A: Rigid for vibrating screeds or high-pressure pours.
4. Post-Use Maintenance: Clean with pH-neutral detergents; avoid abrasive tools. Store flat to prevent warping.
Industry Adoption Insights
· Europe/Australia: Combined with self-consolidating concrete (SCC) for architectural finishes.
· North America: Preferred in tilt-up concrete warehouses for rapid cycle times.
· Asia: Deployed in prefab housing projects to minimize on-site waste.
