Application specification guide

Glass for Stair Treads and Walk-On Panels

Send the project-engineered glass specification and drawings to EVERMADE GLASS for a manufacturing and supply review. This route concerns glass that carries foot traffic, including stair treads and landings; the guards alongside the stair are a separate panel group.

Identify the Walking Surface and Supply Scope

State whether the enquiry is for a tread, landing or another walk-on glass panel, and identify interior or exterior use. Provide the intended access conditions, including regular pedestrian use or controlled maintenance access. Separate tread and landing panels from risers and glass guards in the schedule.

Our review concerns the specified glass supply. Structural stair design, stringers, brackets, installation and project approval need to be coordinated by the responsible project team. A glass-only quotation does not establish the performance of the complete staircase.

Provide the Engineered Construction and Support Details

Send the specified glass-layer and interlayer sequence with the panel dimensions, clear span, bearing details and fixing arrangement. Include the project loads, deflection requirements and any post-breakage criteria with the responsible designer’s documents.

A layer count or total thickness alone does not define a suitable walk-on panel. Feasibility and document availability are reviewed for the proposed construction and support conditions. We do not select a universal tread thickness from a photograph.

Documents for a glass tread or walk-on panel review
InputWhat to identify
ConstructionEach glass ply, its treatment, interlayer product and thickness, layer sequence and finished thickness.
Panel geometryFinished outline, tread or landing dimensions, clear span, holes, notches and exposed edges.
Supports and fixingsBearing locations, frame or bracket details and the interface with the glass.
Design requirementsProject loads, deflection limits, service conditions and required post-breakage behaviour.
Approval evidenceRequired calculations, tests or inspection documents and who approves the complete application.

Three-Ply Build-Up Examples for an RFQ

Multi-ply laminated glass is used for glass treads and walking surfaces. A three-ply construction is one configuration to discuss when preparing the project specification. The examples below explain build-up notation and nominal thickness; they do not select a safe construction for a span or load.

Interlayer grade, ply treatment, support conditions, walking surface and required evidence must be specified together. These examples are separate from the older photographed stair reference and do not describe its actual thickness.

  • Nominal totals are the sum of the listed layers before production tolerances.
  • Neither example states a load rating, maximum span, support detail or slip classification.
  • The responsible project designer selects and approves the construction; manufacturing and evidence availability are reviewed against that specification.

Specify the Walking Surface and Slip Assessment

Identify wet or dry conditions, the intended footwear and the specified slip assessment method and acceptance criteria. If a traction treatment or printed pattern is required, include the finish reference, treated face, pattern direction and its relationship to the panel edge and fixings.

Surface appearance and a photographed pattern are not measured slip-resistance results. The proposed finish, fabrication route and required evidence must be reviewed before it is offered for the order. Any specified wear or replacement layer should be identified as part of the approved construction.

Coordinate Visible Edges and Fabrication

Show the required edge finish, corners, holes and cut-outs on the fabrication drawing. Identify viewing conditions and any limits for layer alignment or exposed-edge appearance. Low-iron material and finish choices should be approved for the complete laminated construction.

Keep dimensions and machining consistent with the final support and fixing drawings. Agree the identification of top surfaces and panel orientation so the supplied pieces can be matched to the installation schedule.

A Recorded Laminated Stair Reference

Our supplied photographs record a stair application identified as three-layer low-iron tempered laminated glass. They provide a visual supply reference, not a load rating, slip classification or standard construction for another stair. A new order requires its own approved layer specification, support details and acceptance requirements.

Agree the Evidence and Production Hold Points

Identify the documents needed at enquiry, drawing approval, first-panel review and dispatch. Keep each requested record linked to the construction, panel mark or batch it covers. Inspection records can be provided and third-party inspection can be coordinated for the agreed scope.

Dimensional inspection, material documents, slip testing and structural assessment answer different questions. Required evidence and its availability must be confirmed for the selected order before a performance claim is made. Complex constructions may need additional review before quotation and production timing can be confirmed.

Send a Tread or Walk-On Glass RFQ

Start with the engineer-specified construction and the available drawings. Include the application, quantities by panel mark, support details, surface requirements, approval documents and delivery destination. Identify any open design items. Production, packing and transport timing are agreed for the complete order.

Discuss a specified glass tread package

Before you enquire

Project questions.

Is stair railing glass the same as tread glass?

No. A tread carries foot traffic; a railing or guard has a different function and design requirements. Separate their panel marks, constructions and supporting documents.

Does three-layer glass automatically have a walk-on load rating?

No. The individual layers, interlayers, span, supports, loads and required post-breakage behaviour must be assessed for the proposed application.

Does frosted or printed glass automatically have a slip classification?

No. Identify the required surface assessment and supporting evidence for the actual finish and use conditions. Visual appearance alone does not establish a slip rating.

Can I start an enquiry before the structural specification is approved?

You can send the available drawings and identify open items for a preliminary discussion. Manufacturing and any performance-related offer need the appropriate project specification and evidence to be confirmed.
