    This hatch solves:

    • Roof access
    • Protects the roof opening
    • Withstands rough handling and exposure to the elements
    • Aluminum Guard Rail System available

    Reduce Costs and Increase Quality

    Reduce maintenance costs by using an aluminum hatch which is naturally corrosion resistant with minimal ongoing maintenance or upkeep.  Aluminum is high strength and is used in planes, cars, trucks, buses, trains, and buildings.  

    Roof Hatches also available in galvanized steel. 

    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 roof hatch, 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.  In addition, aluminum is 100 percent recyclable and retains its properties indefinitely.

    The galvanized steel roof hatches are painted with red oxide primer.
