Cold Storage Door Thickened Stainless Hinge

For those wholesale sourcing heavy-duty door hinges from Yitai Lock, the Cold Storage Door Thickened Stainless Hinge series spans from the compact CL1260 at 153.5g up to the substantial CL1301 at 704.5g — so there's a model matched to most door weights without over-specifying. The CL1260 is the only detachable model in the range, using E-clip retaining rings that allow the door to be lifted off the pin without tools.

Model Options and Dimensions

The Cold Storage Door Thickened Stainless Hinge comes in four models, each sized for a different load range:

· CL1260: 45 × 60mm overall, 6mm leaf thickness, 4×M5 countersunk mounting holes, Φ7mm barrel, barrel height 70mm with 35.5mm knuckle span, frame engagement depth 13.8mm, weight 153.5g — the smallest and lightest model, and the only detachable one in the range

· CL1301: 113.5 × 79.5mm overall, 7×M6 mounting holes, barrel height 99mm with 79.5mm knuckle span, total depth 51.5mm, frame engagement 5.5mm, weight 704.5g — the heaviest model, suited to large cold storage doors

· CL1302: 107 × 110mm overall, 8×M8 mounting holes, barrel height 110mm with 90.5mm knuckle span, total depth 101.5mm (40mm + 54.5mm + 7mm), leaf height 28.5mm, weight 579g — the widest leaf in the range with the largest bolt pattern

· CL1303: 109 × 70mm overall, 5.3mm leaf thickness, 6×M6 mounting holes, barrel height 70mm with 33mm knuckle span, total depth 37.5mm, frame engagement 5.3mm, weight 355g — mid-range size between the CL1260 and the larger models

Model selection for the hinge comes down to door weight, panel thickness, and bolt pattern preference. The CL1302 with its 8×M8 hole pattern is the most anchored of the four; the CL1260 suits lighter doors where the removable pin is a practical feature.

Material and Surface Finish

All four models of the Cold Storage Door Thickened Stainless Hinge are 304 stainless steel with a brushed finish. The brushed surface gives a consistent, directional low-sheen appearance across the hinge face — more refined than a vibratory polish and without the high reflectivity of a mirror finish. It suits the stainless steel door frames and panel surfaces typical of cold storage and food industry cabinet builds.

304 stainless steel on the hinge handles the low-temperature, high-humidity environment of cold storage rooms well, and holds up against the regular cleaning and sanitising cycles that food storage and commercial refrigeration environments typically require. For standard industrial enclosure or garage door applications, the corrosion resistance is more than sufficient for long-term indoor or sheltered outdoor use.

Application Scenarios

The Cold Storage Door Thickened Stainless Hinge is used across a range of heavy-duty door applications:

· Cold storage and freezer room doors — the thickened stainless steel construction and large bolt patterns handle the weight of insulated cold room doors and the repeated cycling of commercial refrigeration access

· Garage doors and large industrial access doors — the CL1301 and CL1302 models with their wider leaf footprints and heavier bolt patterns suit large panel doors that need solid hinge anchoring

· Equipment cabinets and distribution boxes — the CL1260 and CL1303 cover mid-weight enclosure door applications where a stainless hinge is specified for corrosion resistance or finish consistency

· Electrical enclosures — the brushed stainless finish suits enclosures where hardware appearance is part of the specification alongside functional performance

The Cold Storage Door Thickened Stainless Hinge is a practical upgrade over standard-gauge hinges wherever the door weight, use frequency, or environment would put a lighter hinge under stress over time.

FAQ

Q1: What models are available in this range?

 The range includes four models: CL1260 (45×60mm, 153.5g), CL1303 (109×70mm, 355g), CL1302 (107×110mm, 579g), and CL1301 (113.5×79.5mm, 704.5g). All are 304 stainless steel with a brushed finish.

Q2: How is the CL1260 different from the other three models?

The CL1260 is the smallest and lightest model in the range, uses countersunk M5 mounting holes, and is the only detachable model. The other three are larger fixed hinges with non-countersunk bolt holes in M6 or M8 sizes, designed for heavier doors.

Q3: Is 304 stainless steel suitable for cold storage environments?

Yes. 304 stainless steel handles low-temperature, high-humidity environments well and resists the cleaning chemicals used in commercial cold storage and food processing facilities. It's the standard material specification for stainless hardware in these environments.

Q4: What is the surface finish on these hinges?

All four models carry a brushed finish — a directional, low-sheen surface that is more refined than vibratory polish and less reflective than mirror polish. It suits stainless steel door frames and panels in cold storage and industrial environments.

Q5: How do I choose between the four models?

Select based on door weight and panel size. The CL1260 suits lighter doors where removability is useful. The CL1303 covers mid-weight applications. The CL1302 and CL1301 are for heavy doors — the CL1302 has the wider leaf and largest bolt pattern, while the CL1301 is the heaviest single hinge in the range at 704.5g.

Q6: Can these hinges be used on outdoor garage doors?

Yes — 304 stainless steel handles sheltered outdoor use well. For fully exposed coastal or marine environments, it's worth confirming that 304 grade meets the corrosion requirements of the specific location, as highly saline environments may warrant a higher grade such as 316 stainless steel.
