Twin steel plate stringers create a strong and refined staircase structure with clean architectural lines, with tread, railing, finish and lighting options coordinated according to project requirements.


The Double Steel Plate Stairs features twin steel plate stringers positioned along both sides of the stair flight, creating a strong and refined structural expression. Tread construction, railing system, dimensions and finishes can be developed according to project drawings and installation requirements.
Actual project shop drawings are developed according to site dimensions, structural requirements and installation conditions.

Select the structural type, tread construction and railing system according to the architectural design, fixing requirements and project specifications.
Choose between the standard double steel plate structure and the slotted double steel plate structure according to the tread connection detail and architectural requirements.

A conventional double steel plate structure with tread supports coordinated between the two side stringers. Connection details can be engineered according to the selected tread construction and project requirements.

A slotted double steel plate structure with integrated slots developed for tread positioning and connection, creating a clean structural detail while maintaining the architectural expression of the double plate system.
Three tread constructions are available to suit different structural and installation requirements.



Standoff and Spigot are the primary glass railing options, while Multiline and Cable provide additional architectural choices for customized projects.




After the structural configuration is selected, materials and finishes can be coordinated with the overall architectural design.

Timber species, colour, grain and surface treatment can be selected to coordinate with the interior design and overall staircase appearance.
The double steel plate stringers, tread supports and other metal components can be finished in different coating systems and colours to coordinate with the architectural design.

After the railing fixing system is selected, glass type and appearance can be coordinated according to the railing design, structural requirements and project specifications.

Standard transparent appearance for a clean and versatile architectural finish.

Higher visual clarity with reduced green tint for premium frameless applications.

Selected glass tones can be coordinated with the architectural concept.
LED lighting can be integrated according to the selected tread construction, with the fixing position and concealed wiring coordinated during structural detailing.

LED position coordinated beneath the Type A tread construction.

LED position coordinated with the recessed Type B tread detail.

LED position developed according to the Type C tread construction.

Real trial-assembly photography demonstrates the finished lighting effect and concealed LED integration beneath the timber treads.
Structure, tread, railing, finish and optional lighting are coordinated as one complete staircase system for the project.

Real product and trial-assembly details show how the tread, railing, double steel plate stringers, base and landing connections are engineered and assembled.

The tread support is coordinated with the double steel plate stringers to provide accurate positioning, stable support and a clean finished appearance.

Railing fixing is coordinated with the selected tread system and staircase structure.

The engineered base connection transfers the double steel plate structure to the lower-floor structure.

The upper connection coordinates the double steel plate stringers with the landing or upper-floor structure.

From drawing review and double-steel-plate detailing to fabrication and trial assembly, stringer alignment, tread spacing and key connections are checked for dimensional accuracy and installation efficiency.
