Matched to Real Operating Conditions
Marine Dock Grating
Dock and pier access stays wet, receives chloride-rich spray and often dries slowly. The grating brief must identify the exposure zone, slip condition and adjoining metals before choosing stainless 316L, aluminum or a project coating system.
The Challenge
What This Application Demands
Salt spray and chloride deposits remain on horizontal and sheltered surfaces
Tidal splash, rain and algae make walking surfaces persistently wet
Dissimilar-metal contact can introduce galvanic corrosion at supports and fasteners
Removable access panels must stay secured under wind and maintenance traffic
Requirements
Specification Requirements
Confirm these points before ordering — they define the grating.
Marine exposure zone
- Separate atmospheric salt spray, splash, tidal and any immersion conditions
- State washdown frequency, drainage and expected chloride deposition
- Identify sheltered crevices where surfaces dry slowly
Walking surface
- Review serrated or otherwise qualified slip-resistant profiles for wet access
- Confirm opening limits for tools, footwear and public or maintenance traffic
- Keep drain paths clear at frames, curbs and panel joints
Metal interfaces
- List support, fastener and handrail materials
- Coordinate electrical isolation where dissimilar metals meet
- Confirm removable-panel restraint and fixing with the structural designer
Gratings
Recommended Grating Families
Stainless Steel Grating
SS304/316L grating for chemical, food-grade, coastal and hygienic environments — passivated or electro-polished.
View product
Aluminum Grating
Lightweight, corrosion-resistant aluminum bar grating for architectural, marine and light-to-medium duty platforms.
View product
Serrated Steel Grating
Serrated bearing bars for proven slip resistance on wet, oily, snowy or inclined walking surfaces.
View product
I-Bar Grating
An I-shaped bearing-bar profile that reduces material and panel weight where its verified load range suits the project.

Stainless 316L is often considered where chloride resistance and a robust fabricated panel are required, while aluminum can reduce weight and may suit compatible dock structures. Neither choice is automatic: alloy, water chemistry, crevices, fasteners, support metals and maintenance regime must be reviewed together.
Carbon steel with a project-defined marine coating or galvanizing system can be evaluated only where the owner’s corrosion specification allows it. Hot-dip galvanizing, when selected, is stated per ASTM A123 / ISO 1461 or the customer standard and verified by report; this draft page does not claim a fixed coating life or thickness.
- 316L: review chloride level, crevices, fabrication and post-weld treatment
- Aluminum: review alloy, profile capacity and galvanic isolation
- Wet routes: pair material selection with a verified slip-resistant surface
- All options: confirm span, loads, supports and fixing per project
