Sixteen staircase lines and forty-two railing lines make up this family. The spiral record above — from the catalogue's verified details — shows the family's specification culture: a stair is a steel schedule with timber on top, and the gauges are the product. The wider staircase range covers carbon-steel-and-wood spiral compositions and SS304 railing sets; railing lines serve balconies, stairs and terraces across the residential and hospitality programmes the group supplies.
02Safety-Critical Means Document-Critical
Railings and stairs are life-safety elements. Their project specification — heights, loadings, spacings — is set by the building code of the project's market, and compliance documentation for the lines in a schedule should be requested and reviewed before payment. This page records constructions; it does not certify them for any jurisdiction.
Measurement governs this family as it governs joinery: stairs are made to floor-to-floor heights and openings that drawings state optimistically and sites state truthfully. The group's measurement service is the difference between a staircase that installs and a staircase that is negotiated with, on site, at programme prices.
QBuyer Questions
What staircase types are catalogued?
The enumerated range holds 16 staircase lines, with the spiral carbon-steel-and-wood family the most fully recorded; railing lines number 42. Types beyond the listings are confirmed at quotation.
Can railings match a project's metal finishes?
The recorded railing builds use SS304 with the surface treatments of the façade range available in the same catalogue family (powder coating, anodised, PVDF on aluminium systems). Finish matching is a sample-stage conversation.
Who sets the railing heights and loads?
The project's building code and its engineers. The supplier's role is construction to the recorded build and documentation on request — the schedule should name the code requirements the lines are supplied against.
Do stairs ship assembled?
Stair systems ship as components for site assembly; the logistics and installation conversation belongs in the quotation, with floor-to-floor dimensions confirmed by measurement.
