2.5m Custom Bronze Propeller Specially Made For Iranian Clients

This 2.5-meter large four-blade bronze propeller is tailor-made for Iranian clients' ocean-going vessels by EAST OCEAN, designed for local ocean cargo ships and offshore fishing boats. Developed with customized hydrodynamic design, strict dimension control and full production in line with classification society standards, it perfectly adapts to the harsh high-salinity, sediment-rich waters of the Persian Gulf, delivering a well-matched propulsion solution for overseas seagoing vessels.

This large 2.5m propeller is fully developed based on customized digital modeling. Our technical team manually verifies dimensions with high-precision tape measures to check blade diameter, width and curve profiles blade by blade as shown in the photo. All data are adjusted strictly against clients' engine parameters, vessel draft and local water flow conditions, eliminating common defects of generic propellers such as mismatched performance, insufficient thrust and excessive fuel consumption. Permanent markings are engraved on the hub face, clearly stating material grade CU3, diameter 2200, custom model, production year and LIFA brand logo. Full traceability enables easy inspection by overseas marine authorities and meets local maritime compliance requirements in Iran.

It is cast from high-corrosion-resistant CU3 aluminum bronze with recycled refined raw materials, engineered for superior resistance to seawater salt erosion and sediment abrasion. The Persian Gulf features highly saline seawater and seabed sediment and gravel, which cause severe surface wear, cavitation corrosion and blade cracking on ordinary propellers. Our bronze substrate balances high toughness and hardness. Multi-layer precision polishing delivers a dense, ultra-smooth blade surface that resists long-term saltwater rust and sediment scouring, extending service life at sea and cutting clients' overseas maintenance and replacement costs.

Production follows strict dual balance testing, including rough grinding, fine polishing and mirror finishing. Hydrodynamically optimized curved blades suppress cavitation effectively, minimizing hull vibration and sailing noise for smoother long-distance voyages. The integrally cast thickened hub delivers high load capacity to match high-power marine main engines. Keyway dimensions are customized exactly to clients' stern shaft drawings, requiring no on-site secondary machining for fast, convenient onboard installation.

Export packaging fully accounts for long transoceanic transit: red anti-collision edge protectors line all blade edges, the whole unit is wrapped in thick bubble wrap for cushioning, then packed into fumigated solid wooden cases to avoid collision damage and moisture corrosion during overseas shipment. Certified by major international classification societies including CCS, DNV and BV, full inspection reports and material certificates are delivered alongside each unit to satisfy vessel inspection standards in Iran.

Unlike mass-produced standard propellers, this 2.5m custom unit is developed entirely around clients' actual sailing conditions. We provide one-on-one dedicated support covering dimension measurement, material selection and export packaging, balancing long-term seagoing durability, fuel efficiency and overseas regulatory compliance. It stands as a cost-effective custom propeller choice for Middle Eastern ocean-going vessels.
