STAIRCASE RAILINGS

Indoor

Robust and architecturally flexible steel stair solutions for residential, commercial, and public interiors, combining structural strength with modern design. Manufactured from high-quality mild steel or stainless steel, with a variety of finishes including painted, powder-coated, or brushed surfaces to suit diverse interior styles.

Stair designs are fully adjustable to accommodate fire sprinkler systems and compatible with various cladding types such as gypsum board, perforated metal sheets, or aluminum panels. Fire-resistant coatings are available to meet fire safety requirements.

Cosmos Construction offers both fully welded stairs and modular, assembled stairs, depending on the project stage. Assembled stairs, made from small parts, are ideal for late-stage installations where building access is limited and facade openings are already closed.

All stairs are engineered for rigid construction, efficient production, easy installation, and long-term durability, ensuring full compliance with Scandinavian standards including SINTEF, TEK17, and BBR regulations.

Outdoor

Durable and weather-resistant steel stair solutions for outdoor applications in residential, commercial, industrial, and public spaces. Manufactured from robust mild steel or stainless steel, with surface treatments tailored to the project's environmental requirements, including corrosion protection for classes C3, C4, and C5.

Outdoor stairs are equipped with anti-slip steps to ensure safety in all weather conditions and can be customized for integration with fire escape systems, external platforms, or facade structures.

Cosmos Construction ensures rigid structural performance, superior weather resistance, and long service life, meeting all necessary fire resistance requirements and Scandinavian safety standards such as SINTEF, TEK17, and BBR.

All outdoor stair systems are designed for minimal maintenance and feature flexible anchoring solutions to adapt easily to different foundation types and installation conditions.

Spiral

Space-efficient and durable spiral stair solutions for residential, commercial, industrial, and public environments. Manufactured from robust mild steel or stainless steel, combining structural strength with architectural appeal.

Available with various step types to suit project needs: ready-for-concrete steps, industrial gratings, riffled (anti-slip) metal sheets, or premium oak wood treads for a refined interior look.

Cosmos Construction offers standard and customized spiral stair designs, engineered for rigid performance, efficient production, and easy installation on-site, ensuring minimal disruption during construction.

All spiral stairs comply with Scandinavian building regulations, including SINTEF, TEK17, and BBR standards, and can be finished with corrosion-resistant coatings tailored to environmental classes C3, C4, or C5.

Industrial and technical

Heavy-duty steel stair systems engineered for use in industrial plants, production facilities, logistics centers, and utility infrastructure. Cosmos Construction designs and manufactures stairs that meet the highest safety and durability standards for continuous, high-load operation in challenging environments. Our stairs are available in a variety of configurations—straight runs, switchbacks, spiral, or integrated with platforms—and can be customized for specific heights, widths, and load capacities.

Anti-slip grating treads, robust handrails, fire-resistant coatings, and secure anchoring systems ensure safety and long-term performance in indoor and outdoor applications. Manufactured from mild or stainless steel, all systems are hot-dip galvanized for corrosion protection, with optional powder coating for additional durability or visual identification.

Cosmos Construction provides full support with static load calculations, technical documentation, and project-specific engineering to guarantee compliance with operational and industry requirements.
