Curved Glass Manufacturer: Custom Bent Glass to Your Drawing

Curved glass is flat glass bent to a defined radius so a façade, balustrade, lift shaft or feature can follow a curve rather than a flat plane. As a curved glass manufacturer we produce custom bent panels to your drawing — single-curved, compound-curved, and curved laminated or insulated build-ups. This guide explains what a curved glass factory makes, how custom sizing works, why “bent glass” and “curved glass” are the same thing, and what we need to quote.

What a curved glass manufacturer makes

Single-curved (cylindrical) glass — bent to one radius, for curved façades, balustrades, lift shafts and shopfronts.
Compound / double-curved glass — curved on two or more axes for spherical, conical, barrel and free-form shapes.
Curved laminated glass — bent panels laminated with PVB or SGP for safety, overhead and balustrade use.
Curved Low-E and curved insulating units — where thermal performance is needed on a curved opening.

Custom curved glass — made to your size

Every curved panel is defined by its bending radius, dimensions and glass make-up. Single-curved panels are produced 5–25 mm thick, with a bending radius from about 420 mm (process-dependent on thickness and build-up) and sizes up to a soft-axis arc length of 2440 × height 5000 mm. Compound-curved panels are hot-bent on two or more axes and their maximum size is project-specific, confirmed from the drawing rather than a published figure. Because the achievable radius and maximum size depend on thickness and build-up, we confirm feasibility from your drawing instead of quoting one number that will not fit every case.

Bent glass is curved glass

“Bent glass” and “curved glass” describe the same product — glass shaped to a radius by heat bending. So a request for a bent glass manufacturer, bent tempered glass or curved glass supplier is the same scope: we toughen after bending for safety performance, and can laminate or insulate the result. If you have seen the term “bent glass” on a drawing or spec, read it as curved glass here.

How to choose a curved glass manufacturer

Does the factory bend in-house? Bending, tempering, laminating and insulating under one roof keeps the radius, size and build-up consistent.
Will they confirm feasibility from a drawing rather than promise a fixed radius sight-unseen?
Can they laminate and insulate curved panels, not just bend single sheets?
Do they have curved project references at architectural scale?

What to send for a quote

A drawing per curved panel — bending radius, dimensions and orientation.
Glass make-up — tempered, laminated or insulated, and thickness (or the application, so we can advise).
Quantity and any matching flat panels.
Destination and shipping terms (EXW / FOB) and target date.

Minimum order quantity and lead time are confirmed per project — they depend on the shapes, build-ups and volume, so we advise them against your drawing rather than publish a single figure.

Project references

Nanchang East Railway Station — double-curved Low-E tempered insulating glass plus cesium-potassium fire-rated double-curved tempered panels on one envelope (~2,800 m²). See the railway-station façade case.
China Nanotechnology Research Institute — ultra-clear double-curved tempered glass laminated with a 2.28 mm SGP interlayer and sealed into an insulating unit (~4,500 m²). See the research-institute façade case.

FAQ

Is bent glass the same as curved glass? Yes — both describe glass heat-bent to a radius; the terms are interchangeable.

What is the minimum bending radius? From about 420 mm for single-curved glass, depending on thickness and build-up.

What is the maximum curved panel size? Up to a soft-axis arc length of 2440 × height 5000 mm for single-curved panels; compound-curved sizes are project-specific.

Can curved glass be laminated or insulated? Yes — curved laminated glass (PVB or SGP) and curved insulating units are produced, as on the research-institute and railway-station façades.

What do you need to quote curved glass? A drawing per panel with radius, size and build-up, the quantity, and destination/terms.
