Lock, Hinge & Sealing Solutions for Cold Chain & Transport Equipment
Full hardware stack for refrigerated trucks, reefer trailers, ISO reefer containers, and walk-in cold rooms — SUS304/316 truck-body T-handles, 3-point cam-bar rod locks, anti-pilferage recessed cylinders, food-grade EPDM gaskets, and –40 °C low-temperature stainless butt hinges. Engineered for ATP, FSMA STF, HACCP, ISO 1496-2 / 17712, GDP and IP65/66 cold-chain compliance.
Cold-chain hardware is not the same across asset classes. A 7.5-ton city distribution reefer cycles its rear door 30+ times a day and lives or dies by the door gasket and paddle latch. A long-haul reefer trailer needs a 3-point rod cam-bar that holds IP65 sealing and clears FSMA STF + ATP audits. An ISO reefer container demands SUS304/316 and ISO 17712 anti-tamper seals after 720 h of salt spray. A walk-in cold room mandates an internal release latch, food-grade EPDM, and –30 °C-rated stainless butt hinges. Yuxin Electric supplies the full hardware stack — whale-tail T-handles, 3-point rod locks, SUS304 hinges, food-grade gaskets — across all four cold-chain form factors, and engineers the niche items (–40 °C hinges, GDP audit-trail smart locks, drip-channel butt hinges) on demand.
Hardware Across 4 Cold-Chain Form Factors
Refrigerated Light Truck Body
Last-mile cold delivery — single rear roll-up or swing door, 1–2 side service doors, roof-mount chiller. Zinc + SUS304 hardware mix; cycle-life and food-grade gasketing dominate.
See hardware kit →Refrigerated Semi-Trailer
Long-haul reefer — dual rear swing doors with 3-point rod cam-bar, side access door, nose-mount Carrier/Thermo King unit. Anti-theft, FSMA STF, and ATP-aligned hardware.
See hardware kit →Reefer ISO Container
Intermodal sea + rail + road — ISO 1496-2 corner casting frame, end-mount reefer module, ISO 17712 anti-tamper seal locks. Salt-spray ≥720 h SUS304/SUS316 mandatory.
See hardware kit →Walk-In Cold Room
Fixed cold storage — sandwich-panel hinged or sliding door, drip-channel hinges, internal release latch (NFPA 101 life-safety), service hatches. Food-grade SUS304 throughout.

Quantity per representative unit, indicative — actual specs vary by body builder, temperature class (chilled vs. frozen), and target market regulation.
