(DERCHI) operates one of Southern China's largest intelligent manufacturing hubs, delivering precision-engineered facade systems to top-tier contractors across Europe, North America, Oceania, and the Middle East.
We control quality from molten primary billet casting through multi-axis CNC profile milling. Equipped with 800-ton to 3,600-ton extrusion presses, our facility produces 6063-T5 and 6061-T6 structural alloy sections with dimensional wall thickness tolerances conforming to EN 12020-2 and ASTM B221, eliminating profile deflection in oversized floor-to-ceiling spans.
To counter extreme thermal differentials, our windows utilize imported Technoform glass-fiber reinforced polyamide (PA66 GF25) thermal breaks. Assembled via computerized profile knurling, mechanical crimping, and pull-off strength monitoring, our multi-chamber assemblies attain overall window frame thermal values down to Uf ≤ 1.2 W/m²K (Passive House performance).
Engineered for extreme cyclonic and coastal exposure, our impact-rated window lines undergo cyclic air pressure loading and missile impact testing per ASTM E1886/E1996 and AS 2047 N6 ratings (up to 4500 Pa ultimate limit state wind loads). Reinforced with structural silicone glazing (Dow Corning 983) and SentryGlas (SGP) laminated interlayers, we guarantee structural integrity during severe typhoons.
We manufacture custom aluminum fenestration according to rigorous international structural and thermal standards. Compare our standard OEM fabrication parameters against baseline commercial project requirements.
| Engineering Parameter | OEM Custom Factory Standard | Testing & Compliance Standards | Project Impact & Benefit |
|---|---|---|---|
| Alloy Composition & Temper | Virgin A00 ingot 6063-T5 / 6061-T6; Webster hardness ≥ 12 HW | ASTM B221 / EN 755-2 / GB 5237.1 | Eliminates structural fatigue and guarantees uniform wall thickness for high-load facades. |
| Thermal Isolation System | 14.8mm to 34mm PA66 GF25 multi-cavity polyamide struts with aerogel filling options | DIN 4108 / EN ISO 10077-2 / NFRC 100 | Drastically lowers U-values to as low as Uw 0.85 W/m²K, eliminating internal condensation. |
| Surface Treatment & Coating | AkzoNobel / PPG PVDF fluorocarbon (3-coat ≥ 40μm), Qualicoat Class 2 powder, or 25μm hard anodizing | AAMA 2605 / AAMA 611 / ISO 2360 | Resists 4,000+ hours of continuous salt spray test (ASTM B117), ideal for harsh maritime and beachfront projects. |
| Glazing Architecture | Double/Triple IGUs (5+12A+5 up to 8Low-E + 16Ar + 8 + 1.52PVB/SGP + 8); Warm-edge Technoform spacers | EN 1279 / ASTM C1036 / IGCC Certified | Maximizes solar heat gain control (SHGC down to 0.22) and achieves sound insulation up to Rw 45 dB. |
| Hardware & Multi-Point Locks | German Siegenia, Roto, HOPPE, or Sobinco heavy-duty 4-point to 8-point multipoint perimeter locking | EN 13126 / PAS 24 / RC2-RC3 Burglar Resistance | Tested for 200,000+ continuous operational cycles and provides exceptional anti-burglary forced-entry security. |
| Air / Water / Structural Load | Multi-barrier EPDM co-extruded vulcanized gaskets; concealed drainage baffles | EN 12207 Class 4 / EN 12208 Class 9A / AS 2047 / ASTM E283/E330/E331 | Guarantees zero water infiltration under dynamic pressures up to 900 Pa and cyclic hurricane loads. |
Commercial developers, general contractors, and facade consultants are adjusting their sourcing roadmaps to align with stricter embodied carbon regulations, climate resilience demands, and digital project execution. Sourcing from a modern OEM factory involves navigating these critical vectors:
Building certifications such as LEED v4.1, BREEAM, and the EU Corporate Sustainability Due Diligence Directive are demanding verified Environmental Product Declarations (EPDs). The market is moving towards post-consumer recycled aluminum scrap (utilizing secondary melt billets) and hydro-powered smelting. Our factory provides certified low-carbon extrusions that emit under 4.0 kg CO2e per kg of primary aluminum, lowering scope 3 emissions for institutional owners.
Contemporary architectural language dictates concealed sash casements and minimalist sliding track geometries with face dimensions under 20mm. Achieving structural compliance across 3.5-meter to 4.5-meter clear opening heights requires internally ribbed profile geometries, high-modulus carbon-fiber composite stiffeners, and structural adhesive bonding where glass panels become load-bearing structural diaphragm elements.
Procurement is transitioning from static CAD drawing approvals to parametric BIM (Revit/IFC) object exchange embedded with thermal calculations and acoustic metadata. Concurrently, commercial window assemblies now frequently specify integrated brushless concealed 24V actuators, magnetic contact reed switches, and dynamic photovoltaic Low-E glazing interlinked with Building Automation Systems (BAS) via KNX or BACnet protocols.
Technical, logistical, and compliance answers tailored for procurement officers, real estate developers, facade estimators, and architectural engineers.
