Founded in 2003 and located in the hardware hub of Qingdao, CLGR has evolved into a leading manufacturer and exporter of rigging and marine hardware. Our dedication to “Quality First” is reflected in our diverse product catalog, engineered to perform in the harshest environments.
Specialized Fishing & Trawling Gear
A core pillar of our production is our high-performance Fishing & Trawling range. Understanding the extreme demands of deep-sea operations, we provide specialized hardware designed for durability and safety:
High-Strength Shackles & Swivels: Essential for connecting nets and cables, our swivels are designed to prevent line twisting under heavy tension.
Trawling Blocks & Rings: Built to withstand constant friction and high load-bearing requirements.
G-80 Alloy Components: We utilize premium alloy steel and stainless steel to ensure our fishing gear resists the corrosive nature of saltwater while maintaining structural integrity.
Thimbles & Chain Fittings: Precision-engineered to protect wire ropes and ensure seamless connection points in commercial fishing rigs.
Beyond fishing gear, CLGR’s expertise extends to a comprehensive suite of rigging hardware, wire rope fittings, and marine supplies. Our facility is equipped with advanced forging and machining technology, allowing us to maintain strict quality control from raw material to finished product.
The SGS audit confirms that CLGR’s business operations are transparent and reliable. Whether you are in the commercial fishing industry or industrial rigging sector, our SGS-certified processes ensure that every component—from a simple thimble to a heavy-duty trawling swivel—meets the rigorous safety and performance standards our global clients expect.

Q1: What materials are typically used for CLGR’s fishing gear to prevent saltwater corrosion?
A: We primarily use high-grade 304/316 stainless steel and Hot-Dip Galvanized (HDG) alloy steel. The HDG process creates a thick, durable zinc coating that provides superior sacrificial protection against the highly corrosive marine environment compared to standard electro-galvanizing.
Q2: Can CLGR provide Proof Load Test certificates for specific rigging orders?
A: Yes. In addition to our SGS company certification, we can perform Proof Load Testing on our internal testing machines. We provide test reports that specify the Breaking Load Limit (BLL) and Working Load Limit (WLL) to ensure the safety of your lifting or trawling operations.
Q3: How do CLGR trawling swivels handle high-speed rotation under heavy loads?
A: Our specialized trawling swivels are engineered with precision-machined bearing surfaces. This design reduces internal friction, allowing for smooth rotation even when the swivel is under maximum tension, which significantly extends the life of your nets and cables.
Q4: Does CLGR support custom-designed hardware based on specific fishing vessel requirements?
A: Absolutely. We offer OEM and customization services. Our technical team can work from your CAD drawings or physical samples to manufacture specialized components in various grades of steel to meet unique deep-sea or industrial specifications.
Q5: What measures does CLGR take to protect products during long-distance maritime shipping?
A: To ensure products arrive in perfect condition, we use export-grade packaging. This typically involves treating steel items with anti-rust oil, followed by packing in gunny bags or cartons, which are then secured on reinforced iron or fumigation-free pallets and wrapped in stretch film for moisture protection.
