Recently, orders for port terminal renovation and expansion projects and inland waterway shipping upgrades have surged. Qingdao SunKai Marine Supplies Co., Ltd.'s production workshop is operating at full capacity, focusing on mass production of D-type, DA-type, and arch-type dock rubber bumper strips (rubber fenders). These strips are being delivered on schedule to domestic inland waterway ports, coastal terminals, and overseas projects in Southeast Asia. These high-buffering, seawater-corrosion-resistant bumper strips provide a robust safety buffer for ship berthing.
Dock rubber bumper strips are a core component of basic port protection, installed at the pier front, bridge piers, floating docks, yacht marinas, and unloading platforms. When ships are docked or impacted by waves, crash barriers can quickly absorb enormous impact energy, dispersing the hard-hit force between the ship and the concrete dock. This prevents scratches, dents, and damage to the ship's hull, protects the dock structure, and reduces maintenance wear and tear. They are widely applicable to various scenarios including cargo terminals, fishing ports, yacht marinas, inland river docks, and bridge piers for cross-sea bridges.
SunKai Marine maintains high standards in both raw materials and manufacturing processes for its newly launched full series of dock crash barriers. The raw materials are high-content natural rubber with a weather-resistant modified formula, and include UV-resistant and seawater corrosion-resistant additives. They are resistant to cracking, hardening, and delamination even after long-term immersion in seawater and exposure to sun and rain. The internal multi-layered reinforcing skeleton and dense vulcanization molding result in outstanding compressive and tear resistance, and prevent deformation under prolonged high-frequency impacts.
We offer customized products for different working conditions: Small D-type crash barriers are compact and easy to install, suitable for yacht marinas, small pontoons, and logistics unloading shorelines; thickened DA-type crash barriers have higher energy absorption and lower surface pressure, suitable for small and medium-sized cargo ships and fishing boat berths; large-size arched crash barriers have strong load-bearing capacity, meeting the routine berthing needs of thousand-ton vessels.
All crash barriers have pre-drilled standard installation holes and are equipped with galvanized embedded steel plates, making on-site fixing simple. Individually damaged barriers can be replaced later, significantly reducing dock maintenance costs. The entire production process undergoes segmented quality inspection: raw materials are tested for rubber tensile strength and aging resistance upon warehousing; semi-finished product vulcanization is strictly controlled in terms of temperature and time to ensure overall density and absence of air pockets; finished products undergo compression energy absorption testing, salt water immersion durability testing, and heavy object impact simulation testing to ensure that parameters such as energy absorption, reaction force, and compression set meet port industry standards, with sufficient burst safety margin, capable of handling complex working conditions such as tides, waves, and frequent berthing year-round.
Leveraging its stable quality and rapid delivery capabilities, SunKai Marine's dockside crash barriers not only cover coastal ports in Shandong, Jiangsu, and Guangdong provinces in China, but have also been exported in bulk to Southeast Asian shipping markets such as Malaysia, Indonesia, and South Korea, supporting newly built fishing ports and cargo terminals in these regions. Currently, the production line is efficiently completing multiple orders; after packaging and inspection, finished products will be shipped to various project sites in batches, with one-stop support services including size customization, installation drawings, and construction guidance provided simultaneously.
Qingdao SunKai Marine continues to deepen its expertise in the field of marine protection products. In addition to dockside crash barriers, it also mass-produces marine rubber airbags, foam fenders, and marine buoys. In the future, the company will continue to optimize its rubber and plastic formulas and molding processes, launching a new series of lightweight, highly wear-resistant, and long-life crash barriers to provide complete safety protection solutions for domestic and international ports, shipbuilding, and marine engineering projects, contributing to the safe and efficient operation of waterway infrastructure.
