Bollard | A4 | M8520
Stainless steel A4 bollards are intended for mooring boats and ships. The product has no fixed standard and is used where high strength and excellent corrosion resistance are required in marine environments. The AISI 316 design provides high resistance to chlorides and saltwater, ensuring a long service life under continuous exposure to the marine environment. Sold individually.
AREA OF APPLICATION
The product is used in marine environments, port facilities, piers, and quays. It is intended for applications where secure mooring of boats is required, such as securing mooring lines in harbors, and where the material must withstand saltwater, exposure to the elements, and mechanical stress from water movement.

FREQUENTLY ASKED QUESTIONS (FAQ)
What is an A4 stainless steel bollard used for?
A bollard is primarily used as a secure mooring point for boats and ships at piers, quays, and decks. It also functions excellently as a robust barrier or impact post for ground and property installations where a high aesthetic finish and maximum strength are required.
Why choose a bollard in acid-proof A4 steel?
A4 steel (AISI 316 / 1.4401) contains molybdenum, which provides superior protection against saltwater, road salt, and harsh weather conditions. This makes A4 bollards completely maintenance-free against rust and corrosion, unlike simpler steel or A2 grades that can develop surface rust and discoloration in marine or coastal areas.
How is the bollard mounted for optimal strength and stability?
Depending on the model, the bollard is mounted either by welding to steel structures or by bolting to pier decks, stone, or concrete using acid-proof bolts/threaded rods. For maximum load-bearing capacity during mooring, it is recommended to use through-bolts with backing plates or chemical anchors when fastening into concrete.
