3mm 4mm Nashiji obscure pattern glass - Privacy, cut-to-size

3mm 4mm Nashiji obscure pattern glass — field notes from real projects

If you’ve ever stood in a boutique shower room and wondered how the space feels bright yet private—yep, that’s the Nashiji effect. Made in Shahe, Hebei (origin: 800 meters south of Provincial Road 329, Economic Development Zone, Shahe City), this patterned glass has been quietly taking market share from plain frosted sheets. To be honest, the mix of light transmission and image diffusion is hard to beat for bathrooms, partitions, and appliance panels.

What exactly is “Nashiji”?

It’s a rolled patterned glass: molten soda‑lime float is passed through engraved rollers that imprint a pebbled “pear-skin” texture. The result: it transmits light but not detailed images. Standard thickness runs 3–6 mm (sometimes 8–10 mm for doors). Many customers say it “feels softer” than sandblasted glass, with fewer fingerprints in daily use.

Quick specifications

Property	Spec/Range	Notes
Thickness	3 mm, 4 mm (also 5–6 mm; 8–10 mm on request)	Measured per ASTM C1036 / GB/T 9963
Light transmittance	≈72–85% (varies by thickness/pattern depth)	Real-world use may vary with lighting
Obscuration (privacy)	Medium–High	No clear imaging at 0.5–1 m
Standard sizes	1830×2440 mm; 2140×3300 mm	Cut-to-size available
Processing	Annealed; tempering/laminating optional	Safety glazing per EN 12150 / ANSI Z97.1
Edges	Seamed, flat-polish, arrised	CNC cuts for tight tolerances

How it’s made (short and honest)

Materials: premium soda‑lime float.
Process: melting → rolling through Nashiji pattern rollers → controlled cooling (anneal) → cutting/edging → optional tempering or PVB/EVA lamination → cleaning/packing.
QA & testing: dimensional tolerance (ASTM C1036), surface quality (GB/T 9963), safety impact where tempered (EN 12600/ANSI Z97.1), fragmentation for tempered (EN 12150). Service life: ≈20–30 years indoors; ≈10–20 years outdoors with proper sealing and hardware.

Applications and feedback

Shower enclosures and bathroom windows: bright privacy without a “boxed-in” feel.
Office/retail partitions: hides clutter; keeps daylight. Architects like the tactile look.
Home appliances and cabinetry: doors, pantry panels, wardrobe sliders.

Installers tell me 4 mm is a sweet spot for partitions, while 3 mm wins in appliance panels for weight savings. Surprisingly durable in daily cleaning; the pattern helps disguise smudges.

Vendor snapshot (buyers keep asking this)

Vendor	Thickness	MOQ	Lead time	Certifications	Notes
ZR Glass (Hebei)	3–10 mm	≈100 m²	10–18 days	ISO 9001, CCC; CE on tempered	Strong cut-to-size; stable color
Local fabricator A	4–6 mm	Small lot	5–12 days	Varies	Fast for small jobs
Import brand B	3–8 mm	Full crate	4–6 weeks	CE, EN	Consistent but pricier

Customization

Finish options include tempering for safety, PVB/EVA lamination for acoustic/impact, polished or arrised edges, drilled holes, and hardware cutouts. Color tints and acid-etched post-treatment possible (ask for sample swatches). If you need 3mm 4mm Nashiji obscure pattern glass in curved panels—possible, but lead time extends.

Real project notes (quick)

Hotel showers, 4 mm tempered: impact class 2(C)2 per EN 12600; punch-list defects under 1% after transport.
Office retrofit, 3 mm laminated: acoustic gain ≈2–3 dB over single sheet; privacy complaints dropped to near zero.
Retail cabinets, 3 mm annealed: breakage rate

Standards you’ll likely specify: ASTM C1036/C1048, EN 12150 & EN 12600 for safety glazing, ANSI Z97.1 for North America, and GB/T 9963 for patterned glass. For public spaces, I’d always pick tempered or laminated 3mm 4mm Nashiji obscure pattern glass, even if the base sheet passes visual QA—safety first.

Certs and test data at a glance

Factory lots typically ship with ISO 9001 QA traceability, CCC (China Compulsory Certification) where applicable, and CE DoP for tempered variants. Typical light transmittance (4 mm) comes in around 72–78% per lab cards, with haze high enough to obscure faces at ≈0.7 m. Always request current test reports with your PO—conditions change.
