Strong magnet. Sealed build. Easy to prove clean.

Our plate magnets are built for food plants that cannot afford metal in the product. You get a surface field of up to ~10,000 Gauss*, a 100% full-weld stainless steel (SS304, SS316 or SS316L) housing with continuous seal welds, no crevices, no gaps and no exposed fasteners on the product side, and seams finished to a smooth, cleanable surface.

The result is a ferrous foreign-body control that is simple to sanitise, simple to inspect and simple to record, so it fits naturally into your HACCP plan and your ISO 22000 food safety management system.

Need the same hygienic build in bar form? Full-weld magnetic bars and grate magnets are available to order too. Without full weld, bar and grate magnets can use screws or nuts that leave crevices and threads where deposit builds up, so full weld removes them. Stainless grades 304, 316 and 316L are available; confirm the grade at quotation.

*Typical rating. Actual field at the product depends on air gap, plate size and application, so we confirm it with you before you order.

01 / Why it gives you confidence Built for hygiene

Three things your auditor looks for

Strength, cleanability and traceable control. Every plate magnet is designed around all three.

Up to ~10,000 Gauss

High-energy rare-earth magnet assemblies give a strong surface field to catch ferrous fragments, such as iron particles and worn machine parts, as product flows past. Field strength is confirmed for your air gap and product flow.

Rare-earthChuteSuspended

100% full weld

The housing is sealed with continuous seal welds, so there are no open seams for product, moisture or bacteria to hide in. No screws or bolts on the product-contact face. Weld seams are finished to a smooth, cleanable surface.

Seal weldsNo crevicesNo exposed fasteners

Food-grade stainless

Fabricated in SS304, SS316 or SS316L; 316 and 316L generally suit more corrosive or washdown-heavy environments (confirm grade at quotation). Smooth faces and radiused, finished edges make wiping and washing down quick.

Why FULL WELD matters for food safety

Bolted or riveted housings create seams and fastener heads where product and moisture collect. A full-weld plate removes those hiding places.

  • Continuous seal welds — the housing is closed all round, so magnet and internals stay sealed from product, moisture and washdown.
  • No crevices or gaps — nowhere for residue or bacteria to lodge between panels.
  • No exposed fasteners on the product side, so there are no screw heads to trap material or work loose.
  • Smooth, cleanable weld seams — finished so a wipe or wash-down leaves a clean face.
  • Food-grade materials — SS304 / SS316 / SS316L stainless steel (confirm grade at quotation) for the product-contact surfaces.
  • Easy-clean, quick-release options — hinged swing-open or lift-out designs for fast, safe cleaning.
03 / HACCP & ISO 22000 Food safety support

Designed to support your food-safety programme

Ferrous foreign bodies are a recognised physical hazard in food processing. A well-placed, hygienically built plate magnet is a practical control for that hazard. Here is how our design helps you meet hygiene requirements.

Your food-safety needHow the plate magnet design supports it
Physical hazard control (ferrous foreign bodies)Up to ~10,000 Gauss* surface field captures ferrous fragments at the point in the line your HACCP team selects: chute, spout, duct or above a conveyor.
Hygienic equipment design100% full-weld SS304/SS316/SS316L body, no crevices, no exposed fasteners, smooth cleanable finish.
Cleaning and sanitation (prerequisite programme)Hinged or quick-release designs and smooth faces let sanitation crews clean quickly and consistently.
Monitoring and verificationSimple inspection and cleaning checklist below, plus a routine cling/pull test or Gauss-meter reading if your site wants a record.
Food-contact materialsFood-grade stainless steel for product-contact surfaces; tell us your product and cleaning chemicals to choose SS304, SS316 or SS316L.
Traceable documentationWe work with your QA team on drawings and specifications for your records. Ask us what documents you need.
Please note: Arrowmatics does not hold, and does not claim, ISO 22000 or HACCP certification for itself. ISO 22000 and HACCP apply to your food-safety management system and your site. We supply fit-for-purpose, hygienic-design plate magnets that support your programme; customers remain responsible for their own certification, hazard analysis and critical control point decisions.
04 / Inspection & cleaning Ready for your SOP

Plate magnet hygiene checklist

Adapt this to your own SOP. Frequency should follow your hazard analysis and how much ferrous material you find.

  1. Isolate and make safe. Stop the line or divert product. Keep tools, watches and steel items clear of the strong magnet face.
  2. Open or release. Swing the hinged plate open or use the quick-release to lift it out.
  3. Remove and record captured metal. Take off ferrous fragments, note the amount and type, and investigate any change or sudden increase.
  4. Clean the face and seams. Wipe or wash with your approved cleaning method and sanitiser, and confirm nothing remains on the surface.
  5. Inspect the weld seams and face. Look for dents, cracks, pitting, discolouration or damage to the stainless surface. Report any breach of the seal.
  6. Verify performance. Do a cling or pull test with a test piece, or take a Gauss-meter reading on the surface if your programme requires it.
  7. Close, refit and sign off. Return the plate to position, check the latch and mounting, and sign the log.
05 / Designs & custom sizes Made to your line

Plate magnet designs

Hinged for swing-open cleaning, plain for fixed or suspended use, and sized to your chute, duct or conveyor.

Hinged plate magnets Swing-open cleaning

Mounted in chutes, spouts and ducts. The plate swings open on stainless hinges so operators can clear captured ferrous quickly and inspect the face.

Suspended plate magnets Over conveyors

Hung above a belt to lift tramp iron from the product stream. Simple, rugged and easy to reach for cleaning.

Quick-release / lift-out Fast sanitation

Removable designs for lines with frequent sanitation windows. Ask us about latch and handle options that suit your washdown routine.

06 / FAQ Plate magnets, HACCP & ISO 22000

Common questions

Are your plate magnets rated at 10,000 Gauss?

We can build plate magnets with a surface field of up to about 10,000 Gauss. This is a typical rating, not a guarantee for every build. The field at the product depends on the air gap, plate size and how far the product stream sits from the magnet face, so we confirm the right specification with you for your chute, spout or conveyor.

What does FULL WELD mean on a plate magnet?

Full weld means the stainless steel housing is closed with continuous seal welds, so there are no open seams, crevices or gaps where product, moisture or bacteria can lodge, and no exposed screws or bolts on the product-contact face. The weld seams are finished to a smooth, cleanable surface.

Does a full-weld plate magnet help with HACCP?

Yes, it is designed to support your HACCP programme. A sealed, smooth, easy-clean stainless magnet is easier to sanitise and inspect, and it can serve as a ferrous foreign-body control at a point your HACCP team has identified. Your HACCP plan, critical control points and validation remain your own.

Are Arrowmatics or your magnets ISO 22000 certified?

No. We do not claim that Arrowmatics holds ISO 22000 or HACCP certification. ISO 22000 certifies a food safety management system at your site. Our role is to supply fit-for-purpose, hygienic-design plate magnets that support your ISO 22000 and HACCP programme. Customers remain responsible for their own certification.

Which stainless steel do you use: 304, 316 or 316L?

Plate magnet housings can be fabricated in food-grade stainless steel grades 304, 316 and 316L. 316 and 316L generally suit more corrosive or washdown-heavy environments. Tell us your product and sanitiser and we will recommend a grade; please confirm the grade at quotation.

How do I clean and inspect a plate magnet?

Fit a hinged or quick-release design so the plate can be swung open or lifted out, wipe or wash off the captured ferrous material, then inspect the face and weld seams for damage, dents or corrosion, and record the check. Set the cleaning frequency from how much ferrous material you find. See the checklist on this page.

How do we verify the magnet is still performing?

Set a routine in your HACCP or prerequisite programme: visual inspection of the face and welds, a pull or cling test with a test piece, and a Gauss-meter reading on the surface if your site wants a numeric record. Ask us what verification suits your application.

Can you make custom sizes?

Yes. Plate width, length, height, flange or hinge layout and mounting are made to your chute, duct or conveyor drawing. Send a photo, sketch or dimensions on WhatsApp +60 12-211 2522 and we will quote in writing.
