Three Rises to 525 mm
The main module has two ordinary treads and one top platform. Two 250 mm goings plus the 500 mm platform give a 1000 mm horizontal grating-run length.

Galvanized Steel Frames, Grating Treads and a Top Platform
Bolt-Up Galvanized Carbon-Steel Frame
The access module uses numbered carbon-steel stringer/frame components with a galvanized finish. The fabrication schedule identifies member sections, connections, endplates and the corresponding site attachments.
Open Grating Treads and a Deeper Platform
The main module has two 900 mm-wide grating treads with 250 mm goings, followed by a 900 × 500 mm top platform. Its three 175 mm rises place that platform 525 mm above the lower floor.
Two Side Guard and Handrail Runs
A 40 mm round top rail follows each side of the step run and platform. The height basis is 900 mm vertically above the tread-nose line and platform surface, with post and connection details carried on the fabrication drawing.
Three Access Heights with a Common 175 mm Rise
Four Rises to 700 mm
The four-rise option adds a third ordinary tread before the platform. Three 250 mm goings plus 500 mm give a 1250 mm run, with the same 900 mm tread width.
Five Rises to 875 mm
The five-rise option uses four ordinary treads and the same 500 mm-deep top platform. Its 1500 mm run and 875 mm platform height are coordinated with the upper landing.

Module Landings, Frame Connections and Site Attachments
Match the Upper and Lower Floor Levels
The site drawing establishes the lower-floor datum, upper landing and chosen module height. It also locates the platform interface, approach area, doors and surrounding clearances.
Detail the Frame and Anchor Connections
The fabrication package assigns member sections, grating support, bolt groups, baseplates, endplates and site attachments to the actual installation. Supporting substrates and the required engineering criteria travel with those details.
Coordinate Grating and Side Protection
The order records grating bar orientation, edge treatment, post positions and side-rail connections. The project review establishes the guard arrangement, openings, applicable use criteria and required loading documentation.
Grating Access-Step Component Schedule
Rise Count and Module Quantity
Quote three-, four- or five-rise modules by landing reference. Carry the platform height, 900 mm tread width, 250 mm going and total grating-run length together.
Numbered Frame and Grating Components
List stringers, frame members, treads, top platforms and their matched fixing locations. Grating specification, member sections and galvanized-finish requirements use the fabrication schedule.
Side Rails and Site Attachments
Count both side-rail runs, posts, connection plates, bolt sets and site attachments. The upper landing and lower substrate details identify the corresponding fixing assemblies.
Pack Labels and Installation Sequence
Bundle numbered components with the bolt/endplate schedule and landing reference. Protect galvanized surfaces and grating edges, and retain component counts and destination on the packing list.

Galvanized Access-Step Module Questions
How many treads are in the main module?
The three-rise module contains two ordinary grating treads and one deeper top platform. The three walking levels are 175, 350 and 525 mm above the lower floor.
How is the horizontal run calculated?
Each ordinary tread contributes 250 mm of going, and the top platform contributes 500 mm. Two treads plus the platform give 1000 mm; three give 1250 mm; four give 1500 mm.
What are the platform dimensions?
The top platform is 900 mm wide and 500 mm deep. Its height is 525, 700 or 875 mm for the three-, four- or five-rise module respectively.
What is the side-rail height reference?
The two side runs use 40 mm round top rails with a 900 mm vertical height basis above the tread-nose line and platform surface. Posts and connections follow the module fabrication detail.
How are frame sections and attachments specified?
The fabrication package assigns member sections, grating support, bolt groups, endplates, baseplates and anchor details to the actual landing and supporting substrates. The project criteria and engineering documentation use that same assembly.
What is supplied as one module?
One module includes the numbered stringer/frame components, ordinary treads, top platform, two side-rail runs and bolt/endplate schedule. Component labels and the landing reference organize packing and assembly.
