Complete systems for platforms, walkways and stairs. Top rails, knee rails, posts, toe plates, connectors and base fixings — produced in our Nantong factory.
Each layout is set out to the guardrail rules your project must meet, usually ISO 14122-3 or OSHA 1910.29.

01 / DESIGN TO THE RIGHT CODE
Guardrail Requirements by Standard
The same platform can need a different system in Rotterdam than in Houston. Compare the dimensional rules we lay out to.
Requirement
ISO 14122-3:2016
OSHA 29 CFR 1910.29
Guardrail height
At least 1,100 mm
42 in ± 3 in (about 990–1,140 mm)
Intermediate rail
At least one knee rail; clear gap no more than 500 mm
Midrail about midway between top rail and floor
Toe plate / toeboard
At least 100 mm high
At least 3.5 in (89 mm) high
Post spacing
Preferably no more than 1,500 mm
Not fixed; set by the load requirement
Top rail load
Load test defined in the standard
200 lb (890 N) outward or downward
Stair handrail height
Covered in ISO 14122-3 for stairs
30–38 in (760–965 mm)
Summary only. Check the current edition of each standard and any local code for your project. Stair handrail height and stair guardrail height are separate requirements.
02 / ONE MATCHED SYSTEM

06 / COMPONENT
Base fixings
Top-mount or side-mount to steel or concrete
Moulded base foot or side bracket; M12 stainless steel anchors
RAL 1003 Safety yellowRAL 7035 Light grey
Other RAL colours made to order.
Standard resin: fire-retardant isophthalic polyester with UV inhibitor. Vinyl ester is available for chemical areas. Pigment runs through the resin, so colour does not flake off like paint.
03 / CONFIGURED AROUND YOUR SITE
Typical Layouts
Most projects combine several layouts. We draw the details at corners, ends and openings before production.
LAYOUT / 01
Platform and walkway edges
Top rail, knee rail and toe plate on posts at regular centres, with returns at the ends so there is no open gap.
For chemical plants, wastewater works and coastal access routes.
LAYOUT / 02
Rails that follow the stair pitch
Raked rails follow the stair pitch. Where OSHA applies, the handrail height is checked separately from the guardrail height.
Send the number of flights, stair pitch and landing layout.
LAYOUT / 03
Non-conductive access barriers
Around transformers, switch rooms and rail corridors, non-conductive FRP rails avoid an electrically conductive guardrail system.
Confirm the electrical requirements and fixing details for your site.
04 / CHOOSE FOR THE ENVIRONMENT
Compared with Steel and Aluminium
FRP is chosen where corrosion or electricity is the problem. Where neither applies, painted steel or anodised aluminium may cost less up front.
Property
FRP
Galvanised steel
Aluminium
Corrosion
Does not rust; resin chosen for the chemicals present
Rusts once the coating is damaged
Attacked by chlorides and alkalis
Electrical
Non-conductive
Conductive; needs earthing
Conductive; needs earthing
Maintenance
Wash down; no repainting
Periodic recoating
Periodic cleaning
Touch temperature
Stays close to air temperature
Hot in sun, cold in winter

Installation
Bolted; no welding or hot work
Usually welded or bolted
Bolted or riveted
05 / ASSEMBLED WITHOUT WELDING
Installation Sequence
Hand tools and a drill, not a welder. Follow the layout drawing and work through the sequence.
