Frameless Glass Stair Balustrade | Fabrication Drawings
A frameless toughened-glass balustrade up a straight stair: plumb-ended panes set out along the flight, their bottom edge parallel to the nosing line at the pitch of the stair, entered as rise and going, an angle or the overall run and rise. Optional level landing panes at the foot and the head of the stair. Held by stainless spigots standing on the treads or on a stringer that follows the pitch, a base channel along the stringer, or face fixed through holes in the glass into the side of the stringer, with an optional interlinking handrail or slotted cap rail that bends from the pitch to level at the landings. Includes a glass template sheet for the cut shapes, a stair set-out sheet and a side fixing detail.

Frequently Asked Questions
What do I get in the drawing pack?
Each drawing pack is an A4 PDF with orthographic views (front elevation, side elevation, top view, and isometric), full dimension lines, extension lines, and a professional title block. You also get a live 3D preview in the browser and optional STEP file export for CAD software.
Can I use this drawing for fabrication?
Yes. Dimensions are computed to sub-millimetre precision from a true 3D solid model, not approximated from a template. Print the PDF at actual size, hand it to your fabricator, and build from it. Change any input and the entire drawing regenerates in about 60 seconds.
How long does it take to generate a Frameless Glass Stair Balustrade drawing?
Around 60 seconds end-to-end. Geometry computation runs server-side in a CadQuery process with a 30-second per-request timeout; PDF rendering and download account for the rest. If you change a dimension, regeneration takes the same ~60 seconds — there is no manual redrafting step.
Can I save and reload my dimensions for the Frameless Glass Stair Balustrade?
Yes. The free Explorer tier keeps 1 saved drawing, so you always have somewhere to land between visits. Fabricator saves every drawing you make and reloads the configurator in one click, so you can revise a quote, regenerate a clean PDF, or branch a design for a similar customer without re-typing dimensions.
References & technology
Category: Balustrades. Tags: balustrade, railing, glass, frameless, stair. Geometry built with CadQuery on the OCCT (OpenCascade Technology) kernel — the same geometry foundation used in FreeCAD and a number of commercial CAD packages. Drawings are orthographic projections of the computed 3D solid; no view is sketched or scaled from a template.
