Stainless Steel Welded Ring Round Pad Eye Plate with Ring 5mm-8mm

Product Overview

This Ring Round Pad Eye Plate is a one-piece, fully-welded anchor point engineered for maximum load security in harsh marine, outdoor, and architectural environments. CNC-formed from solid 5 mm–8 mm stainless-steel plate and TIG-welded to a closed D-ring, it delivers zero weak seams, zero thread loosening, and zero deformation under rated loads. Manufactured from premium marine-grade 304 or 316L stainless steel, this heavy-duty hardware piece is rigorously tested to ASTM B117 salt-spray standards, guaranteeing a lifetime of rust-free performance even when constantly exposed to corrosive saltwater spray or extreme weather conditions. The substantial weight and cold, smooth metallic touch of the plate convey immediate confidence in its structural integrity. Whether securing heavy maritime rigging or anchoring critical architectural tension structures, this pad eye plate provides an uncompromising foundation that project managers and structural engineers can rely on for decades of maintenance-free service.

Key Features & Advantages

✅ Monoblock welded construction – The base plate and ring are permanently fused in a single pass using a 360° TIG welding process, creating a structure that is 30 % stronger than standard screwed eyes. This ensures zero breakage and a reliable 4:1 safety factor.
✅ Marine 304 or 316L stainless steel – Engineered for lifelong rust-free service, successfully passing rigorous ASTM B117 salt-spray testing to withstand the harshest coastal and offshore environments.
✅ 5 mm / 6 mm / 8 mm stock thickness – Available in multiple heavy-duty profiles to safely cover working loads ranging from 200 kg to 800 kg, providing unyielding support for demanding applications.
✅ Precision investment-cast ring – Featuring a seamless 8 mm Ø solid bar with a 180° perfectly smooth throat that eliminates rope chafe, preserving the lifespan of your synthetic lines and wire ropes.
✅ Dual finish options – Choose between a functional satin wire-drawing finish (standard) or a brilliant 800# mirror polish (OEM) that offers a sleek, reflective visual appeal for premium architectural projects.
✅ Hidden weld foot – Carefully ground flush to allow for zero-gap mounting on both curved and flat surfaces, ensuring a clean aesthetic and preventing moisture accumulation behind the plate.
✅ Universal hole pattern – Precisely machined to fit M6 / M8 stainless bolts, as well as ¼"–5/16" UNC lag screws, offering versatile and rapid installation across various substrates.

Specifications & Dimensions

Accurate dimensional tolerances are critical for structural hardware, and this round pad eye plate is manufactured to exacting specifications to ensure precise alignment during installation. The base plate diameters and hole spacings are CNC-machined to accommodate universal mounting hardware, while the 5 mm to 8 mm thickness options directly correlate with the certified 200 kg to 800 kg working load limits. Every production batch is fully documented and traceable, accompanied by an EN10204 3.1 Mill Test Certificate (MTC) and a comprehensive breaking-load report. This stringent quality control guarantees that the physical dimensions and metallurgical properties meet the strict compliance requirements of industrial, marine, and architectural safety standards. The flush-ground back profile ensures maximum surface contact area, evenly distributing tension loads across the mounting substrate.

Application Scenarios

• Marine deck hardware – Essential for lifeline terminations, heavy block attachments, and fender ties. The corrosion-resistant steel withstands constant saltwater exposure and the dynamic shock loads of rough seas.

• Sailing & rigging – Provides unyielding bobstay, babystay, and jack-line anchor points. The smooth, chafe-free ring ensures that running rigging and safety tethers slide quietly and securely without abrasive wear.

• Aerial yoga & circus – Engineered as ultra-secure ceiling mounts for aerial silks, hammocks, and trapeze rigs. With a certified 800 kg load capacity and a 4:1 safety factor, it guarantees absolute peace of mind for performers and studio owners.

• Architectural tensile structures – Ideal for anchoring cable trellis systems, tensioned shade sails, and heavy glass-canopy brackets. The polished finish complements modern architectural aesthetics while delivering immense holding power against wind sheer.

• Off-road & trailer – Functions as indestructible tie-down eyes for securing ATVs, boat trailers, and expedition roof racks. The low-profile design prevents snagging while keeping heavy cargo locked down over punishing terrain.

FAQ

Q1: Is the ring welded all around?
A: Yes – The ring features a 360° continuous TIG weld that penetrates deeply into the base plate. Each unit is dye-penetrant inspected for micro-fissures and salt-spray tested to ASTM B117 for 1,000 hours to guarantee absolute structural integrity.

Q2: Can I get a load certificate?
A: Absolutely. Each production batch comes with a fully traceable Mill Test Certificate (MTC) EN10204 3.1 and a detailed breaking-load report, ensuring full compliance with rigorous industrial and construction safety regulations.

Q3: Do you supply matching bolts?
A: Yes, we provide an optional one-stop hardware package featuring A4-316 countersunk Torx bolts. Available in 20 mm–60 mm lengths, these bolts are supplied in the exact same finish as the plates for a cohesive, professional appearance.

Q4: What is the MOQ for custom laser logo?
A: We support a highly accessible Minimum Order Quantity (MOQ) of just 100 pcs for customization. High-contrast laser etching or deep electrochemical marking of your proprietary logo is included completely free of charge to enhance your brand visibility.
