DYGLASS Curved Glass: OEM Capabilities, CE Certification, and Precision Customization for Global Projects

When sourcing curved glass for curtain walls, sightseeing elevators, shower rooms, coffee tables, or skylight roofs, procurement teams and project managers need a partner who can deliver complex shapes, strict tolerances, and certified quality. Shenzhen Dayang Special Glass Co., Ltd. (DYGLASS), established in 2017, operates a 30,000 m² factory with 130 employees and an annual output of 600,000 square meters. Their specialization in hot curved glass—including S‑shaped, U‑shaped, double curved, single hot curved, laminated curved, extra large, high precision, and no‑wave distortion curved glass—positions them as a strong candidate for OEM/ODM orders and demanding architectural applications.

Problem Definition: The Challenge of Sourcing High‑Quality Curved Glass

Curved glass is not a commodity. Each project requires specific radii, thicknesses, edge finishes, coatings (low‑iron, UV‑block, sound‑insulated, explosion‑proof), and compliance with regional safety standards. Many buyers struggle to find a supplier that can produce no wave distortion curved glass in large sizes, handle CNC forming for complex geometries, and provide verified CE certification for the European market. Without a reliable partner, projects face delays, rejections, and safety risks.

Industry Background: The Growing Demand for Custom Curved Glass

Architectural trends increasingly favor flowing, curved facades, panoramic elevator glass, and seamless shower enclosures. Double curved and S‑shaped glass are now common in luxury retail, high‑rise buildings, and transportation hubs. At the same time, regulatory bodies in Europe and the Middle East require documented performance data—such as EN 12150‑1 for tempered glass and EN 1449 for laminated glass. DYGLASS meets these challenges through dedicated production lines for concave, convex, and irregular curved glass, combined with in‑house CE compliance.

Detailed Solution: DYGLASS Curved Glass Capabilities

DYGLASS processes any surface shape of multi‑curved tempered glass: double curved, triple curved, trapezoid curved, spherical curved, pyramidal curved, S‑shape curved, cylindrical curved, and positive‑negative curved tempered glass. Their facility includes two tempering lines dedicated to curved glass (flat & curved line; concave & convex curved line & irregular curved line), a double curved tempering line, an autoclave for lamination, and CNC‑controlled cutting, drilling, edge‑grinding, and heat‑soak furnaces. This vertical integration ensures tight tolerances and repeatable quality.

Step‑by‑Step: From Inquiry to Delivery

  1. Design & Specification Review — Share radius, thickness, coating, and edge requirements. DYGLASS confirms feasibility and suggests optimal processing (e.g., single hot curved vs. laminated curved).
  2. CNC Cutting & Shaping — Glass is cut to net shape using CNC machines, including drilling if required.
  3. Edge Grinding — Edges are polished or beveled to spec using an edge grinding line.
  4. Tempering / Heat Soak — Glass is heated and rapidly cooled in curved tempering furnaces; optional heat‑soak testing reduces nickel‑sulfide risk.
  5. Lamination (if required) — PVB, SGP, or EVA interlayers are autoclave‑bonded for laminated curved glass (CE certified under EN 1449:2005).
  6. Quality Inspection — Visual, dimensional, and performance checks ensure no wave distortion and compliance with EN 12150‑1 (tempered) or EN 1279 (insulated).
  7. Packaging & Shipping — Proper wood crates and foam protection for sea/air freight.

Frequently Asked Questions (FAQ)

1. Is DYGLASS curved glass CE certified?

Yes. DYGLASS holds CE certification for tempered glass (EN 12150‑1:2015+A1:2019; certificate BGTC20260403‑02), laminated glass (EN 1449:2005; certificate BGTC20260403‑03), and insulated glass (EN 1279‑1/‑2/‑3/‑4:2018; certificate BGTC20260403‑05), issued by ECTI CERT Ltd. and valid until 2031‑03‑03. These cover curved tempered, curved laminated, and curved insulated glass products.

2. What types of curved glass can DYGLASS produce?

DYGLASS can produce any surface shape of multi‑curved tempered glass, including double curved, triple curved, trapezoid curved, spherical curved, pyramidal curved, S‑shape curved, cylindrical curved, and positive‑negative curved tempered glass. They also offer single hot curved glass, U‑shaped curved glass, laminated curved glass (with PVB/SGP/EVA), extra large curved glass, high precision curved glass, and no wave distortion curved glass.

3. Can DYGLASS customize curved glass for specific dimensions and coatings?

Absolutely. DYGLASS accepts OEM and ODM orders.
