Aluminum Ships Stairs

This stair solves:

  • Ships Stairs (ships ladders) for rooftop access, mezzanine access, or crossover obstacles
  • Four types of Ships Stairs (ships ladders): walk-thru, to roof hatch access, to a platform, or crossover with a platform in the middle
  • Uses less floor space (footprint), if not feasible to use standard stair
  • Easier climb than a vertical ladder

Reduce Costs and Increase Quality

Reduce maintenance costs by using an aluminum stair which is naturally corrosion resistant with minimal ongoing maintenance or upkeep compared to steel stairs that corrode over time.  Reduce installation costs by using an aluminum stair which is a third the weight of steel, so it is easier to install, requiring less equipment.  Aluminum is high strength and is used in planes, cars, trucks, buses, trains, and buildings.  

Reduce Risks

With over 75 years of experience providing access solutions, we know the codes and are experts in this area.  Units are built to meet or exceed OSHA 1910 Subpart D design criteria.  Without the correct stair, there could be injury, liability, and loss of money, which puts companies' reputations and lives at stake.  

Aesthetically Pleasing and Sustainable Material

The standard aluminum mill finish will not rust or stain the surrounding structure.  Powder Coating is available to match the surroundings or stand out for safety. Clear Anodizing is available to increase corrosion, abrasion, and wear resistance.  In addition, aluminum is 100 percent recyclable and retains its properties indefinitely.
