How does the hatch perform in exposed service conditions?

Its heavy-duty construction is intended for hard-working environments where durability, repeat use, and reliable access are critical. Final suitability should be matched to the project conditions and loading requirements.

Can the heavy duty floor hatch be made for larger or project-specific openings?

What safety options are available?

Options can include anti-slip finishes, controlled opening systems, and accessories such as safety grids to support safer operation around the access point.

Enhanced Safety Options

Safety Products

Surespan offers additional safety options for floor access hatches, including a pressure-sensitive edge for electrically operated units, a retractable handhold to assist entry and exit, a Ladder Up Post for vertical access support, and a safety grid for fall protection when the hatch is open.

Enhanced Access Options

Ladder Access

Our floor access products can be paired with several ladder configurations to suit the available space and maintenance strategy. Standard straight ladders provide direct access, while spiral or compact ladders help where floor area is limited. Folding ladders are also available for applications that benefit from a stowed access solution.
