Access Ladders

Surespan access ladders are engineered for safe, dependable vertical access across commercial, industrial, institutional, and service environments. The range includes fixed vertical ladders, ship ladders, companionway ladders, retractable ladders, emergency egress options, and custom-engineered access systems developed to suit roof access, plant access, mezzanines, basements, and other elevated service points.

Manufactured in marine-grade aluminum or galvanized steel depending on the application, these ladder systems are designed around durability, safe climbing geometry, and practical integration with hatches, platforms, guardrails, and surrounding structure. Standard and made-to-specification configurations are available to help project teams resolve challenging access conditions without compromising usability or site safety.

For architects, specifiers, contractors, and facility managers, Surespan provides ladder systems backed by engineering experience, technical coordination, and product options that support both routine maintenance access and more specialized access strategies.

Vertical Access Ladders

Surespan fixed vertical access ladders are designed for permanent access to roofs, plant platforms, service zones, shafts, and other elevated locations where dependable climbing access is required. They can be configured for interior or exterior use and are commonly specified for commercial, industrial, utility, and institutional projects.

Structural ladder geometry: Source dimensions include 1.9 in. OD (48.3 mm) tubular stringers set 15.7 in. (400 mm) apart, with widths from 11.8 to 23.6 in. (300 to 600 mm) and serrated rungs at 9.8 in. (250 mm) centers on first mention.
Material options: Marine-grade aluminum and galvanized steel configurations are available to suit corrosion exposure, duty level, and finish requirements.
Safety integration: Depending on project requirements, systems can incorporate cages, guardrails, locking devices, walk-through tops, and fall-protection provisions. Source references to BS 4211 should be reviewed alongside applicable North American safety and access requirements for the project jurisdiction.
Installation coordination: Standoff brackets, landing interfaces, and wall-clearance details can be aligned with the supporting structure and the intended point of access.
Custom arrangements: Multi-section ladders, rest platforms, and project-specific top and bottom transitions are available where standard details do not suit the site condition.

For U.S. projects, vertical ladders should always be coordinated against the governing safety program, site conditions, and authority requirements before final specification.

Angled Access for Routine Use

Surespan companionway ladders, often referred to as ship ladders, provide a more ergonomic access route for maintenance staff and regular users who need better climbing comfort than a vertical ladder can provide. These systems are often selected for roof hatches, mezzanine access, plant rooms, and basement connections where space is limited but repeated access is expected.

Climbing angle: Source configurations reference ladder angles of approximately 65° to 75°, with stair-type options from 30° to 50° on first mention, helping designers balance footprint and ease of use.
Dimensional coordination: Source dimensions include ladder widths of roughly 17.7 to 21.7 in. (450 to 550 mm), tread spacing of 8.9 to 10.0 in. (225 to 255 mm), and headroom/opening guidance such as 47.2 in. (1.2 m) clearance and 59 x 29.5 in. (1,500 x 750 mm) minimum structural openings where applicable.
Durable construction: Marine-grade aluminum construction, anti-slip treads, continuous handrails, and optional powder coating support long-term use in exposed and interior environments.
Height management: Source material references maximum single climbs of 9.8 ft (3 m) with intermediate landings for greater heights; final layouts should be checked against applicable U.S. safety and access criteria.
Project-specific access: Walk-through tops, up-and-over arrangements, parapet transitions, and other custom ladder forms are available for more complex routing conditions.

These systems are intended to help teams deliver safer, more usable access paths where frequent service access or more controlled climbing geometry is required.

Surespan also offers retractable ladders, zip ladder systems, emergency exit ladders, and custom access assemblies for projects with tighter space constraints or more specialized operational needs.

Retractable ladder systems: Designed for ceiling access and other concealed openings where a permanent exposed ladder is not desirable.
Zip ladder configurations: Used where coordinated access through roof openings or smoke vent assemblies is required.
Emergency egress options: Wall-mounted and drop-down designs can be configured for controlled emergency-use scenarios where appropriate.
Integrated access design: Ladder systems can be paired with roof hatches, guardrails, handrails, and platform details to create a coordinated access package.
Custom engineering: Surespan can adapt dimensions, materials, top transitions, and mounting details to suit the structure and use case.

If you are planning vertical access for a roof, plant platform, mezzanine, shaft, or service area, Surespan can help you develop a ladder solution that aligns with the space, safety strategy, and performance needs of the project. Contact us to discuss your requirements.
