Custom Tee Head Marine Mooring Bollard in Cast Ir | RFQ Sourcing Details

This tee head marine mooring bollard is offered for securing mooring lines at ports, docks, yards, and jetties. The listed nominal capacity options are 5, 20, 30, and 60 tons.

Because the source information does not provide load-test results, engineering drawings, anchor details, or a governing marine standard, buyers should treat these figures as configuration options requiring technical verification rather than as independently validated performance ratings.

Available production materials include gray iron, ductile iron, cast steel, carbon steel, alloy steel, stainless steel grades SS304 and SS316, Duplex 2205, and aluminum. Manufacturing capabilities include sand casting, lost-foam casting, investment casting, gravity casting, and CNC machining.

The appropriate combination should be selected according to the approved drawing, required mechanical properties, corrosion exposure, production volume, and inspection plan.

Available surface treatments include KTL e-coating, zinc plating, mirror polishing, sand blasting, acid pickling, black oxide, painting, hot-dip galvanizing, powder coating, and nickel plating.

Not every treatment is suitable for every base material or marine environment, so coating type, preparation grade, dry-film thickness, color, repair procedure, and corrosion requirements should be specified in the purchase documentation. Customization can be based on a sample, drawing, design, or stated requirements.

OEM and ODM services are listed as available.

Published general casting information includes a casting weight capability from 0.5 kg to 20 tons per piece, surface roughness of Ra 12.5-25 micrometers for cast surfaces, and casting tolerance ranges of CT9-10 for machine molding, CT8-9 for shell molding and lost-foam molding, and CT10-11 for manual sand molding.

These are general manufacturing capabilities and should not be assumed to define the delivered bollard unless they appear on the approved project drawing. The stated quality process includes visual and functional inspection of finished products, followed by an additional check before packing.

Available testing equipment includes a spectrometer, tensile testing machine, hardness testing machine, metallographic microscope, X-ray imaging equipment, coordinate measuring machine, image testing equipment, profiler, and 3D scanner.

Buyers should confirm which inspections, tests, acceptance criteria, material certificates, and reports will apply to their particular order.

Before procurement, request a dimensioned bollard and anchoring drawing, verified nominal capacity definition, design-load basis, material grade, mechanical-property requirements, corrosion-protection system, mounting hardware scope, and foundation interface.

Also confirm whether proof-load or destructive testing is required, which standard governs design and acceptance, whether third-party inspection is needed, and how traceability will be maintained.

Packaging, order quantity, production schedule, and shipping terms should be agreed for the final configuration rather than inferred from general listing data.
