Choose a lifting magnets supplier by checking whether its equipment matches your actual steel loads, handling conditions, and operating process—not by comparing rated capacity alone. Ask suppliers to review the material type, dimensions, surface condition, load shape, lifting method, and required documentation before recommending a magnet. Then compare product information, safety guidance, customization options, lead time, and after-sales support. At Lihua, we recommend sharing a clear application brief so our team can assess the requirements and discuss a suitable lifting-magnet solution.

A lifting magnet can help move compatible ferrous materials without placing slings or clamps around every load. However, the suitability and effective holding capacity depend on factors such as the steel’s thickness, shape, surface condition, and contact with the magnet. A supplier who does not ask about these details may not have enough information to make a sound recommendation. The first step is to describe the job, not simply request a product by its maximum capacity.
Write down what you lift, where you lift it, and how often the operation takes place. Include whether the material is a single plate, a bundle, a bar, a billet, or another form, and explain whether the load is flat, curved, rough, or coated. Also describe the lifting equipment and the route from pickup to set-down. These details help the supplier identify questions that could affect equipment selection and operating instructions.
Give each candidate supplier the same information so that you can compare recommendations fairly. Include the material grade if known, individual-piece and total load weights, dimensions, minimum thickness, surface condition, and the way loads are presented for pickup. State whether the magnet will be used indoors or outdoors, and mention exposure to moisture, dust, heat, or other site conditions. If some details are not yet confirmed, label them as estimates rather than presenting them as final specifications.
For example, an illustrative inquiry might specify a steel plate weighing 1,000 kg, measuring 2,000 mm by 1,000 mm, and having a thickness of 20 mm. Those figures describe a sample request only; they do not establish that a particular magnet is suitable. The supplier still needs to consider the plate’s condition, lifting orientation, magnet contact area, and equipment arrangement. Ask what additional information is needed before a capacity recommendation is made.
Ask the supplier to explain which magnet type is appropriate for your handling pattern and why. Permanent lifting magnets do not rely on a continuous electrical supply to maintain their magnetic field, while electromagnetic systems require an electrical source and a suitable control arrangement. Electro-permanent designs combine electrical switching with a permanent magnetic holding principle, but their operating details and suitability must be confirmed for the specific product. Do not assume that one type is best for every load, duty pattern, or facility.
Also establish whether you need to lift individual pieces or multiple items at once. A magnet intended for a single plate may not be suitable for a bundle, and a system’s ability to handle a load can depend on spacing, alignment, and load geometry. Ask the supplier to identify the intended material and pickup arrangement in its proposal. Where your operation includes different load types, request separate recommendations rather than relying on one broad capacity figure.
Rated capacity is useful only when you understand the conditions behind it. Ask the supplier to explain the rating basis, including the material and dimensions considered, contact conditions, lifting position, and any limitations described in the product documentation. Check whether the proposed magnet suits the thinnest material and the least favorable surface condition in your normal work. If your loads vary significantly, ask for guidance on each relevant case.
Confirm the magnet’s weight, dimensions, attachment method, and compatibility with your crane or other lifting equipment. For electrically powered equipment, request details about the required supply, controls, and the consequences of power interruption, as applicable to the design. For any magnet, clarify inspection, maintenance, storage, and operating requirements. Treat any capacity figure as application-specific unless the supplier’s documentation states the exact conditions under which it applies.

Request the product data sheet, operating instructions, inspection guidance, and any available test or conformity documents relevant to the equipment and destination market. Verify that the documents correspond to the quoted model and configuration. Ask how the operator is expected to engage and release the load, and what checks should be completed before use. A responsible supplier should explain limitations clearly rather than presenting a single capacity number as a guarantee for every situation.
Discuss how the magnet will be used within your site’s lifting procedures and risk controls. Supplier information supports equipment selection, but it does not replace your organization’s assessment of the complete lifting operation. Confirm applicable local requirements with your safety or compliance team, especially for installations, powered systems, and lifting equipment used in regulated environments. Keep the final selection, operating instructions, and inspection records available to relevant personnel.
Evaluate whether the supplier can respond to technical questions, confirm configuration details, and provide clear commercial information. Compare quotation scope, included accessories, packaging, delivery terms, warranty conditions, spare parts availability, and communication process. Ask for a realistic lead-time estimate based on the proposed configuration and order quantity rather than assuming that a catalog model is immediately available. If customization is needed, request a written summary of what changes and what information the supplier needs from you.
For an illustrative production-planning brief, state whether equipment may be needed for an 8-hour shift and whether the lifting pattern is occasional or repetitive. The shift duration is not a universal duty-cycle rating; it is context the supplier can use to ask about frequency, operating intervals, and the appropriate design. Similarly, share expected annual or project quantity if known, but distinguish a forecast from a confirmed order. Clear purchasing information helps both sides identify practical constraints early.
When two quotations differ, ask each supplier to explain the difference in assumptions rather than comparing prices in isolation. One proposal may address a particular load condition or include items that another quotation excludes. A lower initial price does not show whether the product is suitable, documented, or supported for your operation. Record unresolved questions and obtain written clarification before approving the purchase.
Use one specification sheet for all supplier inquiries and keep revisions dated. Separate confirmed facts from estimates, and identify the most demanding load your team expects to handle within the intended application. If load variability is substantial, request a written assessment of representative cases rather than one general recommendation. This makes technical comparisons more transparent and reduces the risk of selecting equipment based on incomplete information.
Before ordering, agree on what will be supplied and what will be verified at delivery. Confirm the model, configuration, accessories, documentation, packaging, and agreed commercial terms against the purchase order. Plan operator familiarization and inspection responsibilities in accordance with the product instructions and your site procedures. These steps help turn a supplier quotation into a usable procurement specification.
The right lifting magnets supplier is one that can connect its recommendation to your real steel-handling conditions and explain the limits of that recommendation. Start with material, load, dimensions, surface, lifting method, and operating pattern; then review magnet type, capacity basis, safety documentation, compatibility, support, and commercial terms. Do not select equipment from a maximum-capacity figure alone, and do not treat illustrative load details as proof of suitability. A clear, written application brief is the most useful starting point for a responsible comparison.
To discuss a B2B steel-handling requirement with Lihua, prepare your load details, lifting setup, operating conditions, expected quantity, and delivery needs. Our team can use that information to review the inquiry and discuss a suitable product configuration and quotation. If you are still collecting specifications, send the confirmed details first and mark estimates clearly. That gives us a practical basis for identifying the next technical and purchasing questions.
