We are Ever-power Greenhouse Gearbox — a focused, single-discipline manufacturer that does one thing and does it well: design, build, and ship precision gearboxes for greenhouse ventilation, shading curtain, and rolling film systems. We are not a general industrial reducer factory adding agriculture as a side product line; we are a dedicated team of mechanical engineers and operations specialists for whom greenhouse drive engineering is the entire business.
Founded in 2010 in Hangzhou, China, we now ship to 50+ countries across five continents, supplying both end-user greenhouse operators and OEM partners under private-label agreements. Our annual production capacity exceeds 10,000 units, and our standard catalogue covers torque ranges from 50 Nm hobby tunnel drives up to 2,000 Nm industrial rack-and-pinion systems.
The reason customers choose us is not only competitive pricing — it is the combination of engineering responsiveness, certified quality, and the willingness to do custom work that European incumbents typically reserve for their largest accounts.

The milestones that shaped us — every step driven by a single principle: do greenhouse drive engineering better than anyone else, and let everything else follow.
We started as a small workshop with five mechanical engineers and a single CNC lathe, focused exclusively on worm gearboxes for greenhouse ventilation systems. First-year output: 800 units, all destined for the domestic Chinese market.
We secured our first international order — 120 units to a Dutch greenhouse builder needing emergency replacements during a supply chain disruption. The relationship taught us European technical expectations and shaped our quality standards.
We achieved full ISO 9001 quality management certification, formalising our design, manufacturing, inspection, and after-sales workflows. This unlocked supply agreements with major European greenhouse system integrators.
Following CE conformity assessment, we launched the GG-SC shading curtain drive series, expanding beyond ventilation into energy screen automation — a category previously dominated by Northern European brands at premium pricing.
We launched a structured OEM/ODM program with NDA-protected workflow, 15-day prototype turnaround, and private-label support. We now produce branded gearbox lines for six greenhouse systems integrators across Europe, Asia, and the Americas.
We released the GG-RP series — complete rack and pinion drive systems for continuous ridge vents on multi-span glasshouses. Our largest single project to date: 640 drive points for a 14-hectare Dutch Venlo glasshouse, delivered in 3 weeks.
We crossed the 50-country distribution milestone, with active customers from Norway to South Africa, Canada to South Korea. Our annual production capacity now exceeds 10,000 units, with a 2,000-unit safety stock buffer for emergency replacement.
We do not have a wall of corporate values poster. We have three operating principles that guide every engineering, manufacturing, and customer decision — the same three since day one.
Every customer inquiry reaches our mechanical engineering team before it reaches commercial. We would rather lose an order because we honestly recommended a smaller specification than win one by overselling. Our reputation depends on technical truth, not closed deals.
Every parameter published in our datasheets — torque, IP rating, noise level, efficiency — is measured under EN/IEC test conditions, not marketing-derived. If you find a measurement we cannot defend with a test report, we replace the unit and refund the order. No exceptions.
3-day dispatch on stock items, 15-day prototype on custom OEM, 24-hour engineering response on every inquiry. Speed is a feature — but never at the cost of quality control. Every unit passes the same multi-stage inspection regardless of order priority.
A 12,000 square metre production facility in Hangzhou's Xiaoshan industrial park, organised around the single goal of greenhouse gearbox production at scale, with full vertical control of every critical manufacturing process.
Single-site manufacturing including raw material warehouse, CNC machining, gear grinding, heat treatment, assembly, testing, and dispatch.
Full vertical integration: from raw bar stock to finished worm shaft and gear wheel. Tolerance class DIN 6 across all gear cutting operations.
Each gearbox undergoes torque, noise, temperature, and IP ingress testing before final pack-out. Test reports archived per batch for 7 years.
Standing inventory of common models reserved for emergency replacement orders — typically dispatched within 48 hours of confirmed order.
We hold all the certifications a serious greenhouse drive supplier should hold — and we are happy to share the audit reports behind each one. CE marking is not a logo we add to packaging; it is a technical file we maintain and update for every product series. ISO 9001 is not a wall plaque; it is the actual operating system of our factory.
Customer factory audits are welcome. We arrange airport pickup, translator if needed, and full tour of the production line including raw material storage, machining, assembly, and testing. Several of our largest OEM partners conduct quarterly audits — and we expect them to continue.
Our customer engagement process is intentionally simple — four stages, transparent timing, no surprises. Most customers experience all four stages within 6 weeks from initial inquiry to gearboxes operating on their greenhouse.
You send application data; we respond with a specification recommendation, indicative price, and any clarifying questions.
Formal quotation with FOB/DDP terms. If you need a sample for in-field evaluation, we dispatch within 5 business days.
Confirmed orders enter production. Every unit passes 5-point inspection: dimensional, torque, noise, IP test, and final visual check.
Pre-shipment inspection (third-party available), export documents, dispatch. Post-installation support reachable directly via engineering.
We are a team of 86 people. We are mechanical engineers, gear-cutting specialists, quality inspectors, export documentation coordinators, and customer support staff. We are not a sales-led organisation; we are an engineering-led organisation that ships products. Our engineering and quality team makes up 41% of total headcount — disproportionately high compared to general industrial reducer manufacturers.
The average tenure in our engineering department is 8.2 years. The reason matters: greenhouse drive engineering is full of edge cases that only deep experience reveals — and we want the same engineer who solved a problem in 2018 to be available in 2026 when a similar problem appears on a different continent.
Hard numbers we publish openly — and stand behind. Every statistic below is audited, sourced from internal ERP records, and verifiable by any customer who requests documentation.
Whether you need a single replacement unit, a bulk catalogue order, or a custom OEM project, our engineering team is the first contact — not a sales representative reading from a script. Send us a message and find out how we work.
