Steel wire rusts. That fact drives more hanger replacement decisions in commercial laundry than any other. Galvanizing applies a zinc coating to the wire surface, standing between the steel core and the moisture, detergent residue, and humidity that define a working laundry. Galvanized wire hangers are the value baseline, chosen when the goal is rust resistance at the lowest cost per piece.
The galvanized range spans 1.75 mm to 2.6 mm, in 16 inch and 18 inch lengths, packing at 500 pieces per carton. Understanding what the zinc coating does, where it performs, where it does not, and how to inspect it determines whether a galvanized order delivers its full service life or fails early.
Galvanizing applies a zinc layer to steel wire through a hot-dip or electroplating process. The zinc serves two functions. It acts as a physical barrier between steel and the environment, blocking moisture and oxygen. It also acts as a sacrificial coating: where the surface is scratched, the zinc corrodes preferentially, protecting the steel beneath.
The site describes the finish as providing rust resistance and durability, with a smooth and bright surface. That brightness is the zinc layer itself. The smoothness matters because rough coating creates friction points that snag fabric and indicates inconsistent coverage that corrodes faster in thin spots.
The key distinction for buyers is between galvanizing as a process and as a quality outcome. A hanger can be galvanized and still have patchy coverage. Wire diameter is customisable from 1.75 mm to 2.6 mm, and inspection must confirm coverage quality rather than simply that a zinc step was performed.
Galvanized wire hangers earn their place in dry cleaning shops, laundry businesses, and garment factories where hangers are handled in volume, stored indoors, and exposed to ambient humidity. The site lists the application as dry cleaner and laundry shop for both 16 inch and 18 inch galvanized models.
The 16 inch galvanized notched hanger handles standard adult garments: shirts, blouses, and lighter jackets. The 18 inch galvanized shirt hanger extends to larger shirts and jackets, with the site noting 18-inch length is ideal for those garments. Both pack at 500 pieces per carton.
Galvanized hangers are the value baseline because the zinc step adds less cost than powder coating or PVC sleeving. For high-volume orders that difference compounds. The trade-off is no colour customisation and no anti-slip texture, so galvanized is the wrong choice where branding or wet-garment handling is the priority.
The galvanized range spans 1.75 mm to 2.6 mm, covering the widest band of any finish. Powder coated wire starts at 1.9 mm and PVC coated at 2.3 mm, so galvanized is the only finish on the thinnest wire, meaning lower steel cost per hanger.
Named models exist within the band: a 16 inch 1.9 mm galvanized metal wire hanger, a 16 inch 2.2 mm galvanized wire hanger for suits, and a 16 inch 13G galvanized wire hanger. These designations confirm the factory produces defined diameter variants.
The choice follows garment weight. A 1.75 mm hanger suits shirts where the hanger is a transit tool. A 2.2 mm or 2.6 mm hanger handles heavier garments and resists bending on conveyors. Specifying 1.9 mm covers most general dry cleaning work without paying for unnecessary steel.
The site describes the galvanized surface as smooth and bright. That is a quality indicator, not a cosmetic note. A bright, uniform surface indicates consistent zinc coverage. A dull or patchy surface indicates thin spots where rust first appears.
Bright finish results from even zinc flow freezing with a smooth sheen. Dull patches can indicate uneven wire preparation, contamination preventing zinc adhesion, or a process temperature outside the optimal range. Any produce a hanger that is technically galvanized but will not deliver the rust resistance being paid for.
During inspection, hold a sample under direct light and look for reflectivity variations across the shoulder bar, hook, and twist. Dull bands near the twist or hook are common because forming deforms the wire there. If more than two of ten sampled hangers show dull patches, the batch has a coating consistency problem.
A laundry is a corrosive environment. Humidity from washing and pressing, detergent residues, solvent vapours, and temperature swings all attack exposed steel. The site notes PVC coated hangers block moisture and detergent from reaching the steel, acknowledging those as the primary corrosion drivers.
Galvanized wire hangers resist this through the zinc barrier, but resistance has limits. Hangers on open racks in a humid pressing area corrode faster than those in a dry goods room. Hangers used for damp garments transfer moisture directly to the wire, and repeated wet cycles deplete zinc faster.
The mitigation is storage discipline. Keep galvanized hangers dry, away from direct steam, and rotate stock. If your operation routinely hangs wet garments, the PVC coated range at 2.3 mm to 4 mm is the correct choice, because the full wrapping isolates steel from moisture entirely.
Both finishes are available across overlapping wire diameters, and choosing between them is a common decision. The framework: match the finish to what damages the garment and what the operation requires.
Galvanized wire runs 1.75 mm to 2.6 mm and offers rust resistance with a smooth, bright surface at the lowest cost. It is the default for high-volume indoor handling. Powder coated iron wire runs 1.9 mm to 2.6 mm and adds colour customisation and a surface the site describes as protecting clothing.
Choose galvanized when cost per piece matters and no colour is needed. Choose powder coated when chain branding requires colour or lighter fabrics benefit from a coated surface. Powder coating adds cost and on heavy wire thickness can vary. Both finishes require incoming inspection.
Inspection of galvanized hangers on arrival checks four points. First, measure wire diameter with a caliper at the shoulder bar away from the bend, on at least ten hangers from random cartons. The diameter should match the specified figure within the 1.75 mm to 2.6 mm band.
Second, examine the zinc coating for brightness and uniformity. The site specifies a smooth, bright surface, so dull patches, rough spots, or discolouration indicate inconsistent coverage. Pay attention to the twist and hook where forming may have stretched the coating.
Third, check the hook formation. The hook should be closed, square to the bar, and formed cleanly without a parting line. A hook that opens under light finger pressure indicates thin wire at the tolerance limit or a worn forming press.
Fourth, count the pieces. Open three cartons at random and verify 500 pieces per carton. A short count indicates a counting problem that will recur.
The zinc coating depletes over time through oxidation, and the rate depends on storage. A carton in a dry, ventilated warehouse retains its coating for years. The same carton against an exterior wall with condensation, or in a humid plant, will show white rust within weeks.
White rust is a zinc oxidation product appearing as a chalky deposit. It is not structural failure, but indicates the zinc is actively corroding. Hangers with white rust should be moved to a dry environment and used first.
The site does not publish a service life figure, and no honest supplier can give one without knowing storage conditions. The buyer must control those conditions: store cartons off the floor, away from walls, dry, and rotate stock first-in-first-out.
The economic case rests on comparing coating cost against replacement cost. A bare iron wire hanger is cheaper but rusts in a laundry within months, staining garments. The zinc coating adds a production step and cost, but extends service life enough to make the hanger viable.
The site positions galvanized wire as providing rust resistance and durability. The galvanized range at 1.75 mm to 2.6 mm covers the thinnest and cheapest wire, meaning the coating is applied to the most cost-sensitive products.
Where rust cost is highest, on wet garments and in humid storage, a heavier coating is justified. PVC coated hangers at 2.3 mm to 4 mm block moisture entirely and prevent fabric staining. For standard dry indoor use, galvanized is the right economic choice.
A realistic purchase order states acceptance criteria. State wire diameter and tolerance against the 1.75 mm to 2.6 mm range. State the finish requirement: smooth and bright surface with no dull or rough patches.
State pack quantity: 500 pieces per carton for both 16 inch and 18 inch laundry wire hangers. State total quantity in pieces and cartons. Confirm length: 16 inch or 18 inch, with 18 inch noted as ideal for larger shirts and jackets.
Request a pre-production sample before mass production. The sample confirms diameter, finish, and forming geometry. The final inspection before shipment is the last chance to catch a coating or counting problem. Trade terms: FOB, CFR, CIF, EXW, FCA or express delivery, with T/T at 30 percent deposit and 70 percent against bill of lading scan.
The galvanized range spans 1.75 mm to 2.6 mm, the widest band of any finish. Named models include a 16 inch 1.9 mm galvanized hanger, a 16 inch 2.2 mm galvanized hanger for suits, and a 16 inch 13G galvanized wire hanger. Both 16 inch and 18 inch lengths are available, all packing at 500 pieces per carton.
Galvanizing applies a zinc coating that acts as a physical barrier blocking moisture and oxygen from the steel surface, and as a sacrificial layer that corrodes preferentially where the coating is scratched. The site describes the finish as providing rust resistance and durability with a smooth, bright surface. The coating depletes over time based on storage conditions.
Galvanized wire runs 1.75 mm to 2.6 mm and offers rust resistance at the lowest cost with no colour option. Powder coated iron wire runs 1.9 mm to 2.6 mm and adds colour customisation and a softer surface against fabric. Galvanized suits high-volume general handling; powder coating is chosen where branding colour or fabric protection is the priority.
Store cartons off the floor, away from exterior walls, in a dry and ventilated area. Rotate stock on a first-in-first-out basis so hangers do not sit unused in humid conditions. White rust, a chalky zinc deposit, indicates excessive moisture exposure. Hangers showing white rust should be moved to a dry environment and used before the steel is exposed.
Measure wire diameter with a caliper on at least ten hangers from random cartons, confirming it falls within the specified 1.75 mm to 2.6 mm range. Examine the zinc coating for brightness and uniformity, checking the twist and hook for dull patches. Verify hook closure and formation. Open three cartons and count pieces to confirm 500 per carton.
