Source outdoor stairs for terraces, gardens and commercial projects through Sibolla, a one-stop project supplier with its own factory and specialist production partners. We coordinate exposure, drainage, support conditions and tread performance with your project team.
Start with the tread and structure your project needs, then confirm the outdoor exposure and finish specification.
Consider cast-in-place or precast construction for terraces, entrances and landscape connections. Broom finish, exposed aggregate and stone cladding provide different surface options.
Confirm the supporting structure, finish, drainage and freeze-thaw requirements for the project climate.
Choose solid stone treads or stone cladding over a supporting structure. Options include granite, bluestone, basalt, limestone and travertine.
Match stone type, surface texture, edge profile and fixing method to wet use, exposure and the agreed maintenance plan.
Composite/WPC and treated timber provide a wood appearance for deck and garden stairs. Select the board and supporting stringer as a coordinated assembly.
Confirm wet-slip data, board spacing, movement allowances, fasteners and care requirements for the selected product.
Steel allows straight, switchback, mono-stringer and spiral layouts with coordinated landings. Galvanized, coated or stainless-steel specifications depend on the exposure.
Choose the tread, corrosion-protection system and connections together. Service-access or escape-stair applications need project-specific design and approval.
An outdoor staircase needs an agreed structure, finish and water-management plan. We coordinate the supply package with your design team before the production drawings are approved.

| Project item | Configuration to discuss | Confirm before production |
|---|---|---|
| Climate and exposure | Rain, humidity, coastal salts, freeze-thaw conditions or covered exterior use. | Identify the project location, cleaning conditions and exposure of each flight. |
| Material and protection | Concrete or stone system; composite/treated timber; galvanized, coated or stainless-steel specification. | Agree substrate, metal grade where applicable, coating system, cut-edge treatment and compatible fixings. |
| Tread surface and drainage | Surface texture, nosing, open grating or board joints, and a clear route for water. | Request wet-use slip information for the selected surface; review drainage and any snow or ice exposure. |
| Structure and connections | Flights, stringers, landings, base plates and attachment to the building. | Coordinate total rise, available run, supports, foundations, anchor details and loads with the project engineer. |
| Guards and access | Handrails, guard infill, landings, lighting and the intended route. | Confirm local geometry, guard and access requirements for the actual building use. |
| Inspection and maintenance | Cleaning access, coating inspection, fixing checks and replaceable parts. | Agree the care instructions and inspection intervals for the selected materials and environment. |
Configure each step for safety, drainage, and visual consistency. Available materials include broom-finish concrete, exposed aggregate, natural stone slabs, composite/WPC decking, metal grating, and formed steel treads.
Riser height, tread depth, and nosing profiles are adjustable, with optional anti-slip inserts, drainage channels, and integrated LED step lighting to meet local codes and project aesthetics.
Complete the system with code-compliant railings engineered for durability and outdoor exposure. Choose from steel, aluminum, stainless steel, glass, cable, or rod infill with round or flat handrails.
We coordinate guard height and spacing, provide child-safe infills, and apply long-life finishes (galvanized, powder-coated, or marine-grade stainless). Optional wood-touch rails and integrated handrail lighting deliver a refined, finished installation.
Using a real project installation as a reference, we demonstrate how an outdoor staircase is assembled with structural accuracy and clean detailing. The build features a stainless-steel mono-stringer paired with durable treads and a weather-resistant glass balustrade. Close-up installation stages highlight accurate alignment, secure anchoring, and smooth on-site assembly — delivering exterior stair systems built for long-term stability and refined appearance.
For background on stair components and layout terms, see the overview of stairs. Outdoor exposure, drainage and finish specifications require a separate project review.
An outdoor staircase is an exterior-grade stair system engineered to connect different elevations across patios, decks, gardens, and public walkways. It is designed to withstand rain, UV exposure, temperature variation, and heavy foot traffic while remaining safe and low-maintenance.
Weather-Engineered Performance: Anti-slip treads, drainage detailing, UV and freeze-thaw resistance, and corrosion-protected hardware.
Flexible Layouts: Straight, switchback, curved, or spiral configurations suited to tight outdoor spaces.
Customizable Construction: Select materials such as concrete, stone, composite, or steel, along with railing style, finish, and color.
Structural Reliability: Reinforced frameworks with certified anchors and engineered load calculations.
Code-Compliant Safety: Proper rise/run ratios, guard heights, lighting integration, and slip protection.
Efficient Installation: Prefabricated modules or on-site assembly for minimal disruption and durable results.
Suitable for decks, terraces, roof gardens, pool zones, and public access areas where durability, safety, and design must work together.
Planning outdoor stairs for a building project? These questions cover product selection, site coordination and the information our team needs before production.
Describe the climate and exposure before choosing the structure, coating and fixings. Tread drainage, slip performance and a maintenance plan also need review. An indoor finish should not be assumed suitable outdoors.
Yes. We can coordinate the stair and railing package against the approved drawings. Your project team should confirm the structural connections and local requirements for the intended access route.
Send exposure, drainage, support conditions and tread performance, together with quantities, the destination and your required delivery date. We identify the details needing approval and confirm the scope, production requirements and quotation for your project.
Discuss the required material or finish samples and any prototype at quotation stage. We confirm availability, cost and timing for the selected products. Record the approved sample and drawing references before production so inspection has a clear basis.
Yes. Sibolla combines its own factory with specialist production partners and one project supply team. We can coordinate this package with custom staircases and building materials. Confirm quantities, specifications and shipment phases together so the order follows your installation plan.
