These salvage magnets are all steel-shell encased neodymium pot magnets, specially designed for underwater metal recovery, magnetic lifting, and heavy-duty salvage applications. The steel housing provides robust protection for the internal magnet against impact, corrosion, and shear force damage, ensuring stable performance even in harsh underwater environments. Custom logo engraving and tailored designs/specifications are available to meet diverse customer requirements.

The single-sided non-hole salvage magnet features a solid, unperforated steel shell with only one strong magnetic surface, offering a wider range of standard size options compared to the straight-hole salvage magnet.

The straight-hole salvage magnet has a central through-hole in the steel housing, allowing for quick mounting with bolts, shackles, or ropes for flexible connection in salvage operations.

Double-sided single-ring and double-sided double-ring salvage magnets are designed with magnetic attraction on both sides of the magnet body.

The single-ring version has one central lifting eye bolt for concentrated connection, while the double-ring version features two lifting eye bolts (typically on opposite sides) for balanced pulling force, ideal for high-load salvage tasks.

3.The main types of Fishing Magnets

Single-sided Non-hole Salvage Magnet:The single-sided non-hole salvage magnet is a solid steel-shell pot magnet with only one magnetic attraction surface, featuring no through-hole in the housing. It is available in a wider range of standard size options, making it suitable for basic salvage tasks where a simple, high-strength magnetic surface is required without additional connection points. The enclosed steel shell fully protects the magnet from damage during underwater impacts, ensuring long-term reliability in general metal recovery scenarios.

Straight-hole Salvage Magnet:The straight-hole salvage magnet is designed with a central through-hole in the steel housing, allowing direct insertion of bolts, shackles, or ropes for quick and secure connection in salvage operations. It maintains the same robust steel shell protection for the magnet while offering flexible mounting options, making it ideal for scenarios requiring adjustable connection methods, such as deep-water salvage or multi-angle pulling tasks.

Double-sided Single-ring Salvage Magnet:The double-sided single-ring salvage magnet features magnetic attraction on both sides of the steel-shell magnet body, with one central lifting eye bolt for concentrated connection. It allows simultaneous adsorption of metal objects from two directions, while the single lifting ring provides a single point of force for pulling, making it suitable for balanced, moderate-load salvage tasks where bidirectional magnetic holding is needed.

Double-sided Double-ring Salvage Magnet:The double-sided double-ring salvage magnet has magnetic attraction on both sides of the steel-shell magnet body, with two lifting eye bolts typically mounted on opposite sides of the housing. This design provides balanced pulling force distribution, preventing uneven stress on the magnet during high-load salvage operations. It is ideal for heavy-duty recovery tasks where stable, dual-point connection and bidirectional magnetic adsorption are required.

The whole product line accepts non-standard customization, and one-to-one customized development is available according to customers’ on-site installation conditions, size limits and load requirements.
