Engineered for extreme structural durability, high-traffic commercial resistance, and architectural elegance.
A decade of direct B2B manufacturing, global project scaling, and premium architectural glass engineering.
Established in 2014 (with historical roots dating back to 1993), Shandong Envi Doors and Windows Co., Ltd. has evolved into a powerhouse in the aluminum door, window, and structural glass entrance systems market. Covering a massive production facility of 100,000 square meters, our operation runs with advanced extrusion, surface treatment, and deep fabrication workshops.
Our annual structural extrusion output has reached 50,000 tons of building-grade and industrial-grade aluminum profiles, with an annual output value exceeding 1 billion Yuan. Our systems integrate thermal-insulation barriers, windproof engineering, and custom structural glass configurations that meet diverse global building codes.
Modern commercial projects demand facade systems that combine aesthetic grandeur with high structural and thermal performative benchmarks. The Chinese aluminum glass door cluster, particularly in production hubs like Shandong, represents the most vertically integrated supply chain in the world.
This vertical integration spans raw materials procurement, specialized structural thermal break extrusion, heavy-tonnage CNC milling, automated anodizing, and glass configuration assembly. B2B procurement professionals, architects, and estate developers gain immediate cost advantages, minimized logistical friction, and certified quality controls (SGCC, CE, AS/NZS 2208) that align with international structural codes.
| Supply Chain Layer | Traditional Fragmentation | Shandong Envi Integrated Model | Strategic Benefit to Buyers |
|---|---|---|---|
| Raw Material Sourcing | External sourcing of billets, higher risk of alloy contamination. | Direct partnership with local top-tier primary aluminum suppliers. | High purity 6063-T5/T6 alloy profiles ensuring structural resilience. |
| Extrusion Capabilities | Relies on third-party extrusion facilities with limited tonnage. | In-house 600-ton to 2,500-ton extrusion presses. | Custom thick-walled profiles for high windload structures. |
| Surface Treatment | Outsourced painting/coating; vulnerable to finish degradation. | Integrated anodizing, electrophoresis, and powder spraying lines. | AAMA 2604/2605 compliant finishes resistant to salt-spray and UV. |
| Glass Processing | Logistical lag in transporting glass elements to assembly point. | Direct assembly lines for Insulating, Laminated, Low-E & privacy glass. | Zero transport damage risk, custom thermal performance ratios. |
Our structural solutions utilize "Broken Bridge" (Thermal Break) Aluminum profiles. Uninsulated aluminum acts as a thermal conductor, accelerating energy loss in cold climates and heat penetration in tropical zones. By inserting a reinforced polyamide thermal barrier strip (such as PA66 GF25), we interrupt the thermal path, boosting the system's thermal resistance.
We offer customizable glazing configurations depending on regional building energy codes (such as ASHRAE 90.1, NFRC standards, or EU thermal regulations):
Engineered with multi-chambered EPDM weather-stripping gaskets, our glass entrance doors provide:

For overseas B2B purchasers, sourcing glass entrance doors from China requires verified alignment with destination building codes. Different markets have rigid legal performance thresholds for safety glazing, insulation performance, and wind resistance:
Compliance with NFRC ratings for U-factor and SHGC. Safety glass units are tested in accordance with ANSI Z97.1 and SGCC certifications. For coastal regions like Florida, we provide storm-impact structures tested to withstand high structural wind-loading.
All commercial and residential swing, bifold, and sliding door units carry CE Marking conforming to EN 14351-1. Glazing components conform to EN 12150 safety standards, ensuring thermal performance compliance for energy-efficient commercial facades.
Structural window and door frame configurations are engineered to meet AS2047 performance test parameters. Architectural safety glass options strictly comply with AS/NZS 2208 certification requirements for overhead and safety glazing.
Our architectural entrance configurations are engineered for localized application demands, optimizing materials to suit environmental conditions and usage rates:
Direct answers to the most common technical and logistics questions from B2B buyers.
Standard specifications or fully customized variants engineered to match architectural requirements.
