Bolted metal staircases, custom-made and in kit form

StarModul galvanized steel stairs, prefabricated and assembled with bolted connectors, without welding. We manufacture them to measure based on the required height and available space, for indoor or outdoor use: lofts, mezzanines, warehouses, industrial buildings, terraces, home access, and technical platforms.

Features of a StarModul steel staircase

Two galvanized steel tube stringers, steps fixed with bolted corner brackets, and tube handrails. Parts arrive cut and identified, with all hardware included, for on-site assembly without welding. Pictured: a straight staircase with galvanized steel grating (tramex) steps installed in an industrial building.

• Straight staircase custom-made to your height and space requirements.
• Galvanized steel grating (tramex) steps; please consult us for other finishes.
• Tube handrail on one or both sides.
• Can be integrated into a StarModul steel structure: porch, loft, home, or industrial building.

Prefabricated indoor, outdoor, and industrial steel stairs

Galvanized steel protects the staircase from corrosion, making it suitable for both indoor and outdoor use: for accessing a terrace or a home, for exterior access, or for a mezzanine. In industrial buildings, warehouses, and machinery platforms, the staircase is dimensioned according to the intended use and load capacity.

Advantages of a bolted staircase

• No on-site welding: no welder or hot work required.
• Fast assembly: arrives prefabricated, with pre-cut parts and hardware included.
• Dismountable: can be disassembled, relocated, or expanded.
• Galvanized steel: corrosion-resistant, also suitable for outdoor use.

Measurements required for your custom staircase

1. The total height to be covered, from finished floor to finished floor.
2. The available floor space (length of the opening) and your desired width.
3. The use case: residential, outdoor, industrial, or public.
4. Whether it requires a handrail on one or both sides, and its start and end points.

As a reference, the Technical Building Code (CTE DB SUA) requires a minimum tread of 28 cm and a riser between 13 and 18.5 cm for general-use stairs; higher steps are permitted in residential (restricted use) settings. Using your measurements, we calculate the number of steps and prepare your quote.
