Weizhengheng Group is a China-based steel structure and cold storage solutions provider with 23+ years of experience — and we ship Cam-lock Cold Room Panels to over 30 countries. Every panel is manufactured in our 48,000 m² smart factory (daily output: 5,000 m²), fully certified to ISO 9001, CE (EN 1090), and SGS standards. Unlike generic suppliers, we control the entire process: from raw material sourcing and lab-tested insulation cores (rock wool, PU, EPS) to final packaging — so you get consistent quality, not just a quote.
Our Cam-lock panels eliminate three costly cold room failures: First, no cold bridging — because every joint uses reinforced aluminum cam-lock fittings + full perimeter sealing, verified by thermal imaging tests (U-value as low as 0.22 W/m²K at -25°C). Second, no panel loosening — each lock withstands ≥1,200 N tensile force (tested per EN 14509), and panels stay flat even after 5+ years of daily door cycling. Third, no customs delays — all export shipments include CE DoC, fire test reports (B1 classification per GB 8624), REACH compliance docs, and pre-verified UL-listed options upon request.
You’re not buying panels — you’re buying faster project closure, lower lifetime energy bills, and zero installation surprises. Whether you’re retrofitting an aging food warehouse in Nigeria, building a pharma-grade freezer in Brazil, or scaling cold chain capacity across Southeast Asia — we deliver custom-sized, pre-labeled, surface-protected panels in ≤25 days, with on-site supervision and bilingual engineering support.
