Why is galvanised steel the standard for external stairs?

Hot-dipped galvanising involves coating the steel in molten zinc. This creates a metallurgical bond that is more durable than paint, protecting the structure from the oxidisation caused by rain and humidity. It is the most cost-effective way to ensure a maintenance-free life cycle for outdoor steelwork.

: Can external stairs be attached to existing silos or tanks?

Yes, our design team uses 3D site scanning to map the structure and height of your existing external assets. We then engineer bespoke mounting brackets and support structures that provide a secure fit without compromising the integrity of your tanks or silos.

Do these stairs meet fire safety requirements?

While this stair type is primarily for operational access, our external industrial stairs are built using non-combustible materials. If the primary purpose of the staircase is emergency egress, we can adjust the design to include wider treads, closed steps, and specific landing requirements to meet fire escape standards. Please see our Fire Escapes page for more detail

What are External Stairs?

External metal stairs are durable, weather-resistant stair systems designed to provide safe access between levels outside industrial, commercial, and public buildings. Commonly used for fire escapes, service access, and entry points, these structures are built to withstand harsh environmental conditions while maintaining safety and reliability. External steel staircases play a key role in ensuring safe movement, emergency egress, and compliance with building and safety regulations.
