Curved glass with the geometry recorded

Curved glass, bent glass panels and bespoke cylindrical glazing

Curved glass starts with geometry. Radius, chord, arc length, rise and bend axis describe different aspects of the panel. A clear drawing should identify which glass face or centre line defines the radius and how the panel connects to its supports.

Curved annealed glass, toughened curves, curved laminates and curved insulating units use different production routes. Minimum radius and available dimensions depend on the processor, glass thickness, coating and construction. No single universal bending limit covers them all.

Display cabinets, partitions and curved shopfronts can have very different optical and safety requirements. Include templates or survey information where a new pane must match an existing curve. Agree tolerances and the expected visual appearance before manufacture.

Curved glass with the geometry recorded for your project

Common enquiry briefs include display or furniture, curved partition, shopfront, curved balustrade. Describe the intended use and the supporting construction so the supplier can assess the complete specification. Different applications can need different glass processing, fixings and installation details.

A radius needs a reference

Inner-face and outer-face radii differ. A drawing should state the bend axis and reference surface.

Agree the process

Annealed, heat-treated and laminated curves have different production routes and available geometries.

What to include in a made-to-measure quote

Compare quotes using the same dimensions, quantities, finish, glass construction and installation scope. If you have a drawing or an existing specification, include its reference and identify which details still need advice.

• Glass construction: Manufacturing capability depends on geometry and processing.
• Bend geometry: Use the notes for radius, chord, arc length, rise and the bend axis.
• Radius reference: Confirm which glass surface the radius is measured to.
• Appearance: Colour and finish are requests; confirm a sample before ordering.

Cut-to-size dimensions, edges and fabrication

Measure the finished glass only when the fitting allowances and support details are known. Otherwise identify the opening or existing panel you measured and request a survey. Give each different size its own basket line, with its quantity and drawing reference.

Holes, cut-outs, shaped edges and interfaces with hardware should be settled before manufacture. The finished glass construction and any coatings must suit the intended environment. A screen preview or concept photograph cannot replace a sample, survey or product-specific installation drawing.

Supplier checks before manufacture

• Minimum radius is specific to the processor, thickness, coating and shape; no universal limit is assumed.
• Confirm tolerances, templates and optical appearance before manufacture.

Requesting comparable glass quotes

Save the choices you know and ask for help with the rest. The quote basket records a specification request rather than placing a manufacturing order. A firm quote needs an agreed final build, dimensions, delivery arrangements and any installation or design work.

When comparing proposals, check that glass-only supply and supply with fitting cover the same scope. Ask who provides measurement, drawings, supports, compatible hardware, lifting access and finishing work. Keep the final approved specification with the order.
