Offshore & Marine Platform Grating
Offshore and marine structures need walkway and platform grating that survives constant salt spray, carries crew and equipment loads, and is light enough to lift onto a deck or vessel without heavy cranage.
Engineering considerations
Corrosion is the governing factor: in a splash-zone, hot-dip galvanized steel has a finite coating life, so projects increasingly specify FRP or aluminium for long maintenance-free service.
Weight matters offshore — every tonne lifted has a cost — which favours FRP (about a quarter of steel) and swage-locked aluminium. Non-conductive, non-sparking FRP is also valued near process and electrical equipment.
Loads are still real: helideck access, equipment skids and crew traffic set the bearing-bar size and span, so material choice is balanced against load and deflection.
GoGrating's approach
For marine work we typically recommend moulded or pultruded FRP for corrosion-critical areas and swage-locked aluminium where light weight and removability matter, with galvanized steel reserved for sheltered structural zones. Panels are fabricated to drawing with banded edges, cut-outs and matching stair treads.
What we deliver
Custom-fabricated panels, FRP or aluminium handrail and structural shapes, serrated tops for wet-deck grip, and export packing for sea freight — supplied factory-direct from Anping.
Standards & compliance
Material and coating to ASTM/ISO equivalents; load selection guided by ANSI/NAAMM MBG 531 and project loading.
FAQ
What grating is best for offshore platforms?
FRP and aluminium are usually preferred offshore because they resist salt corrosion and are light to lift; galvanized steel suits sheltered structural areas. The final choice balances corrosion, weight and load.
Why is FRP used on marine structures?
FRP does not corrode in salt water, is non-conductive and non-sparking, and weighs about a quarter of steel — all major advantages on offshore and marine decks.
