The arc-matching rule: the precise dance between C-type hooks and stainless steel coils
Beneath the workshop's dome, red C-shaped hooks flex like steel knuckles, precisely grasping stainless steel coils wrapped in protective paper. These delicate coils, destined for food processing equipment, medical devices, and building curtain walls, are "encircled" by the C-shaped hooks, ensuring even the smallest detail of care during lifting.

1. The "Gentle Hard Power" of the C-Type Hook
Opening Philosophy: The customized C-shaped curved surface perfectly conforms to the curvature of the coil's inner hole. During lifting, the contact surface pressure is ≤5MPa (well below the yield threshold of stainless steel surfaces), leaving no scratches even on mirror-polished 316L coils.
Load-bearing Frame: The main body is constructed of Q690 high-strength steel, with a tensile strength exceeding 700MPa. With a single hook rated load of 50t, it can easily lift a 1.5m diameter, 30t heavy 2205 duplex steel coil as easily as flipping a piece of paper.
Anti-Twist Lock: The hook features a built-in self-aligning bearing, locking the coil's swing to ≤2°. This ensures the coil's end face remains flat (≤0.5mm deviation) even during the final meter of storage and transportation. II. The Industrial Logic of Protecting "Stainlessness"
The value of stainless steel coils lies in their "damage-free" surfaces—the mirror-like finish of food-grade 304 and the pure intergranularity of medical-grade 316L, both of which cannot tolerate even the slightest scratch. The C-type hook, with its "curved surface fit + flexible contact" design, transforms lifting from "rough handling" into "precision connection": the protective paper remains intact, the rolled edges remain undamaged, and the surface remains scratch-free, ensuring that every coil of stainless steel flows to the production line in perfect condition.
In the steel jungle, the C-type hook is an industrial poet of contrasts: it uses tough steel to create gentle support; it uses mechanical precision to protect the purity of the material—this is the "first dignity" of the stainless steel industry chain, from storage to processing.
