Chengyi Aluminum’s Core Strength in Curtain Wall Systems: 19 extrusion production lines and a fully integrated industrial chain, supplying both domestic engineering projects and international export markets.

I. Advantage 1: Full‑chain in‑house production, with no outsourcing or subcontracting, ensuring end-to-end quality control.

The vast majority of aluminum panel manufacturers merely perform processing, sourcing base materials and outsourcing coating, resulting in ineffective oversight across multiple layers of subcontracting. By contrast, Chengyi operates its own aluminum profile rolling and extrusion facilities, producing base materials in-house, and employs fully automated fluorocarbon coating lines. Its CNC bending, engraving, and hyperbolic‑shaped processing workshops are all company‑owned, with each stage subject to in‑house inspection. Upon shipment, products undergo triple quality checks: spectral analysis of the base material, coating thickness measurement, and dimensional tolerance verification—all conducted simultaneously—ensuring that no substandard materials or workmanship slip through. Standardized quality‑control procedures include: spectral testing of incoming base materials; CNC machining and dimensional verification; coating thickness measurement; flatness inspection of finished panels; and a comprehensive visual inspection prior to packaging. A complete set of test reports is issued and delivered with every shipment.

II. Advantage 2: With 19 large-scale extrusion production lines and ample capacity across two manufacturing sites, we ensure on-time delivery even during peak seasons.

During the industry’s peak season (March–October), factories are swamped with orders, pushing lead times to over 20 days. At Orange Easy’s two major plants in Tianjin and Shandong, 19 extrusion lines operate in tandem, delivering a daily capacity of 20,000 m² of curtain‑wall aluminum panels. We maintain a ready stock of 1,000 tons of 3003/6063 base material, ensuring standard flat panels can be delivered within 7 days. For large-scale projects involving millions of square meters, production is allocated across specialized sub‑plants. Contracts clearly specify delay‑penalty clauses, enabling stable delivery for both domestic construction projects and overseas full‑container‑load orders.

III. Advantage 3: In-house production of all alloy grades, covering 1060/3003/5005/6061/6063, and suitable for climates worldwide.

No need to source base materials externally—custom‑matched to suit diverse regional conditions, from China’s inland and coastal areas to the high‑temperature climates of the Middle East and the extreme cold of Europe and North America. With ample inventory, there’s no waiting for material procurement. Our 5005 high‑corrosion‑resistant alloy is tailored for Middle Eastern and island‑export markets; our 6061 high‑strength sheet is designed for ultra‑tall landmark projects; and our 3003 rust‑proof sheet is ideal for domestic coastal urban renewal initiatives. We provide a one‑stop solution, supplying all required base materials without the hassle of comparing quotes from multiple suppliers. Standardized base‑material weights and thicknesses ensure precise pricing, with no hidden markups.

IV. Advantage 4: A complete surface‑treatment production line; in‑house manufacturing of PVDF/FEVE coatings, with a 15‑year coating warranty.

Most manufacturers outsource their coating processes, resulting in fluorocarbon coatings with substandard fluorine content. In contrast, Chengyi’s fully automated, enclosed coating facility produces PVDF coatings with three coats and two baking cycles, achieving a fluorine content of ≥70%. For export markets, we exclusively offer FEVE ultra‑weather‑resistant coatings. We independently manufacture a full range of finishes—including wood‑grain and stone‑grain transfer prints, anodizing, and nano‑self‑cleaning coatings—ensuring uniform coating thickness and exceptional resistance to UV radiation and acid‑rain corrosion. We provide SGS weather‑resistance test reports, and our products are widely recognized by domestic public‑construction projects and high‑end overseas developments.

5. Advantage 5: CNC precision machining, a dedicated workshop for hyperbolic and irregular-shaped parts, with tolerances of ±0.5 mm, addressing the key challenges in shaping and machining.

Small and medium-sized factories can only process standard flat panels; double-curved and large-radius curved shapes must be outsourced, resulting in poor precision and long lead times. OrangeEasy is equipped with five-axis CNC bending machines and 3D engraving centers, along with an independent workshop dedicated to complex double‑curved and irregular‑shaped fabrication. We can handle any intricate curved surface, openwork carving, or gradient‑perforated designs. Our engineers provide free modeling and deliver CAD construction drawings, while overseas projects include English‑language structural verification drawings. On‑site installation ensures zero material waste, reducing general contractor labor costs.

VI. Advantage 6: Comprehensive international and domestic certifications, providing one-stop solutions to meet tendering and export clearance requirements.

In-house certifications: ISO 9001 quality management system, CE EU construction‑material certification, RoHS environmental compliance testing, SGS weather‑resistance, fire‑retardancy, and material‑composition testing, as well as green building‑material certification—available in both Chinese and English. These credentials are directly accepted for domestic government, school, and hospital procurement tenders, and facilitate seamless customs clearance in the Middle East, Europe, the United States, and Southeast Asia, eliminating the need for buyers to incur additional costs for third‑party testing.

VII. Advantage 7: Flexible supply policy—capable of handling both small and large orders, with a low minimum order threshold.

Standard industry manufacturers typically require a minimum order quantity of 50㎡ and do not accept small‑scale sample or storefront‑renovation orders. Orange Easy offers ready‑stock flat panels with a minimum order of 10㎡, fast prototyping in 3–5 days, and full reimbursement of sampling fees when you place a bulk order. For domestic projects, we support phased deliveries to ease on‑site storage pressures. For international trade, we provide 10㎡ sample trial orders, allow mixed‑style shipments in small containers, and offer tiered pricing for large‑container bulk purchases—balancing the needs of small and micro clients with those of major general contractors and overseas traders.

8. Advantage 8: A dual after-sales service system—domestic and overseas—with 24-hour technical support and an extended warranty.

We have established an in‑country engineering and after‑sales team that provides on‑site technical guidance. For international business, we assign dedicated overseas technical specialists who offer 24/7 online support, with instant responses to English‑language drawings and technical inquiries. We offer a standard 10‑year warranty on powder‑coated panels, and a 15‑year warranty on premium fluorocarbon/FEVE coatings. In the event of quality issues, we will replace affected panels at no charge and provide lifetime technical guidance on coating maintenance.
