For float glass, IGUs and glazing work, the right glove is a balance of ISO 13997 cut performance, real grip on smooth panes and low transfer risk. Buyers should specify liner yarn, knit gauge, coating, cuff, AQL, MOQ, lead time and realistic EXW or FOB pricing instead of buying on vague cut-resistant claims.
Start With the Glass Surface and the Handling Step
For glass handling gloves, separate the job before you ask for a quotation. Unloading float glass from A-frames, moving sealed IGUs, feeding shower panels to a washer line and clearing scrap from a break-out table are different risks. A glove that feels secure on dry warehouse stock can lose grip on dusty, lightly condensed or release-powdered panes. For routine finished-pane transfer with only occasional edge contact, EN 388:2016+A1:2018 code 4X43D is a sensible baseline. If operators are touching broken edges, rack burrs or offcuts, quote a second option at 4X44F and price that upgrade before sampling. US buyers should also ask for the ANSI/ISEA 105 cut target, normally A4 to A6 tested by ASTM F2992. Do not buy against vague wording such as cut resistant or CE approved. The quotation should show the full EN 388 code, the ISO 13997 letter, and whether the sample is intended for clean pane transfer or for scrap and breakage.
Build the Liner Around Dexterity, Not Marketing Fibre Names
In a seamless knit-and-dip factory, the normal platform is a 13 gauge or 18 gauge liner built from HPPE or UHMWPE, then blended with steel fibre, glass fibre or para-aramid plus about 3 to 5 percent spandex for recovery. Thirteen gauge is the workhorse for stillages, packs and rack edges because it is more forgiving in production and usually gives better abrasion life. Eighteen gauge gives finer finger feel for spacer bars, clips, suction-cup handles and small fittings, but the yarn cost is higher and machine settings are less tolerant. Glass fibre is often the lower-cost route to level D or F, but after hard abrasion the ends can fuzz and that matters on finished glass. Steel blends usually hold ISO 13997 results more steadily and wear longer, but some operators find them stiffer. A common mid-market build is 13 gauge HPPE plus steel at 4X43D. If the job involves direct knife contact, chainmail or butcher mesh is a different product family; a knit-and-dip glove is not the right answer.
Choose Coating for Smooth Glass, Dust and Light Moisture
For smooth architectural glass, palm coating matters more than a pretty sample. PU palm coatings are thin and tidy, and they suit very clean dry assembly, but on glass they are often too dry and start skating once the pane carries dust or light moisture. For most glazing and window programmes, start with nitrile foam or sandy nitrile. Sandy nitrile gives better mechanical bite on large panes taken from vertical racks, especially where operators cannot pinch hard because they are using suction lifters or carrying by the edge. Where wear is high, a smooth nitrile base with a sandy top finish, or a heavier double-dip nitrile construction, usually lasts longer than a single thin dip. Smooth nitrile is still useful if the same team handles metal frames, rack grease or wet sealant because it wipes cleaner than open-cell foam. Latex crinkle can grip aggressively, but it is not my first choice for low-iron, coated or decorative glass because the surface feels harsher. Approve samples on dry, dusty and lightly misted panes, not on a sales-office desk test.
Cleanliness Is a Separate Specification
A glove can pass EN 388 and still fail the job if it leaves lint, black transfer or an oily feel on the pane. The usual causes are under-cured dark coatings, unstable shell dye, broken glass-fibre ends or a hand-made sample that does not match the normal dip line. Ask for pilot pairs pulled from regular production, then run two simple checks in-house: wipe a cleaned pane under strong side light after ten minutes of handling, and do a white tape-lift test on the palm and fingertips to look for loose fibre or coating dust. If the downstream process includes adhesive bonding, edge-seal application, lamination or low-E coated glass, say so before sampling. A general glove factory can reduce obvious silicone sources in print ink, release agents and packing materials, but it is not an ISO 14644 cleanroom and should not promise particle counts or zero contamination. Standard knit wrists are usually 6 to 7 cm. Where wrists brush sharp edges, move to about 10 cm extended cuffs or specify a separate cut sleeve rather than assuming the glove alone covers the arm.
Write a Purchase Spec That a Factory Can Actually Run
Weak purchase descriptions create most sourcing disputes. Cut resistant glass glove is not a production spec. A usable line item states liner yarn, machine gauge, coating chemistry, coating coverage, target EN 388 code, ANSI target if needed, shell and palm colours, size range, cuff length, logo method and packing. A workable example is: 13 gauge HPPE plus steel liner, sandy nitrile 3/4 dip, EN 388 4X43D, ANSI A4, sizes 8 to 11, grey shell, black palm, knit wrist 7 cm, one-colour back print, bulk packed 120 pairs per carton. Write inspection terms down as well. AQL 2.5 major and 4.0 minor is still the most common export basis, with checkpoints on size marking, pair weight, cuff length, coating voids, shell contamination, left-right pairing and carton marks. Pair weight tolerance is often kept within plus or minus 5 percent, and cuff length within about 5 mm. Size ratio matters too; many industrial programmes move closer to 8, 9, 10, 11 in a 1:2:2:1 split. For EU sale, ask for EN ISO 21420, EN 388 and the EU Declaration of Conformity under Regulation 2016/425 for Category II PPE tied to the exact glove construction.
MOQ, Lead Time and Price From a China Factory View
From a China factory view, efficient MOQ on a standard 13 gauge glass glove with grey shell and black nitrile palm is usually 3,000 to 5,000 pairs per colour with a normal size mix. Move to 18 gauge, custom shell colours, special coating shades or heavier steel content and the practical MOQ often rises to 5,000 to 10,000 pairs because yarn planning and dip-line scheduling tighten up. Pre-production samples take about 7 to 10 days if yarn is in stock; custom lab dips, retail bags or printed header cards usually add several days. Bulk production is commonly 30 to 40 days after sample approval and deposit, with another 5 to 7 days if retail packing is complicated. Broad export pricing is usually around US$1.10 to US$1.90 per pair EXW for a level D build, and about US$2.00 to US$3.40 EXW for a level F glove with more steel or a heavier nitrile build. FOB Ningbo or Shanghai is standard; CIF should be treated as a freight estimate, not a fixed glove cost. Typical packing is 12 pairs per inner bag and 120 or 144 pairs per master carton. A 40 ft HQ container usually plans at roughly 162,000 to 174,000 pairs on simple bulk packing without pallets.
