Heavy-Duty Kidney Bollards for Safe and Reliable Mooring
SME’s Kidney Bollards series offers reliable mooring solutions for docks, berths, and vessels of all sizes. Our products cover 15 ton, 30 ton, 50 ton, 80 ton, 100 ton, 125 ton, 150 ton, and 200 ton, meeting the needs of various ports and ships. The bollards are classified as Type A (light), Type B (medium), and Type C (heavy), suitable for different vessel sizes: A for <500GT, B for 500~3000GT, and C for >3000GT.
The kidney-shaped design distributes tension evenly, enhancing mooring stability. This unique structure ensures high durability in harsh marine conditions. We use premium materials and advanced manufacturing to deliver long-lasting performance. Cast iron (HT250) suits inland vessels, cast steel (ZG230-450) works for seagoing ships, and stainless steel (316L) resists corrosion in harsh environments. Our Cast Steel Bollards are perfect for heavy-duty mooring, providing superior strength and reliability.

Each bollard meets international standards such as ISO 3913, which requires a minimum breaking strength ≥1.5 times the design load. Products also comply with BS 6349, as well as DNV-GL and BV approvals. SME’s Cast Steel Bollards are trusted by ports and shipyards worldwide for secure vessel mooring.
To further protect ports, SME provides fixed fenders and foam fenders, which integrate seamlessly with kidney bollards. This combination improves operational efficiency and extends quay infrastructure life.
As a leading manufacturer and supplier of bollards, SME delivers secure, reliable solutions from small docks to large commercial ports. Choose SME to safeguard vessels, protect quays, and ensure smooth port operations worldwide.
