Structural Wind Load Resistance

Engineered to withstand extreme structural pressure differentials exceeding 4500 Pa (equivalent to Category 5 hurricane winds). Profile corner gussets are crimped using heavy hydraulic corner keys and sealed with two-component polyurethane corner adhesive.

Acoustic Decibel Isolation

Utilizing multi-layered EPDM weatherstripping gaskets and asymmetric double-glazed acoustic laminated glass, our custom storm doors achieve Sound Transmission Class (STC) ratings up to 45 dB, keeping urban noise outside.

Anodizing & PVDF Finishes

Offered in custom RAL powder coating, authentic wood grain transfers, and hard-anodized architectural finishes designed to endure high UV exposure and harsh coastal salt-spray environments without chalking or fading.

Macro Industry Solutions for Global Procurement Partners

Tailored OEM/ODM architectural solutions fulfilling the strategic, legal, and structural mandates of international developers and distributors.

Residential Housing Developments

High-volume custom aluminum storm doors for master-planned suburban communities. Designed for fast jobsite installation with self-storing glass panels, integrated roll-away screen mesh systems, and pre-drilled installation flanges.

Coastal Commercial Storefronts

Heavy-duty shopfront storm entry systems designed to comply with strict high-velocity hurricane zone (HVHZ) building codes. Equipped with heavy-gauge 6061-T6 structural sub-frames and low-E energy efficient glass matrixes.

Architectural Renovation Projects

Custom retrofitting options that allow historical and modern building owners to add secondary storm protection without disrupting primary entry door architecture. Custom arch shapes, divided lite grilles, and vintage finishes available.

China Industry 4.0: Supply Chain Resilience & Manufacturing Efficiency

How Zenit leverages China's advanced industrial ecosystem and integrated raw material supply lines to provide cost, capacity, and quality advantages.

Full Vertical Integration

From raw aluminum ingot processing and die design to extrusion, thermal break stripping, powder coating, glass tempering, and final assembly—our integrated supply chain minimizes outsourced delays.

Flexible Modular Tooling

Our in-house CNC toolmaker room enables rapid prototype production within 7 to 10 days for custom extrusions. This allows B2B clients to test custom architectural profiles with minimal upfront capital risk.

Automated Precision Milling

State-of-the-art 5-axis CNC machining centers perform milling, lock-hole routing, hinge pocketing, and corner keying with sub-millimeter tolerances (±0.1mm), eliminating human assembly errors.

Scalable Freight Logistics

Strategically located in Chengdu's industrial hub with direct multimodal rail and sea export routes, guaranteeing container shipment continuity and standardized export packaging with custom wood crates.

Vacuum Insulating Glass (VIG)

Migrating from standard argon-filled Low-E double glazing to ultra-thin Vacuum Insulated Glass units, achieving glass U-factors as low as 0.6 W/m²K while reducing total sash weight by up to 40%.

Low-Carbon Recycled Alloys

Pioneering the use of post-consumer recycled aluminum billets extruded using clean hydro-electric power in Western China, targeting a 65% reduction in embodied carbon across our OEM production footprint by 2028.

Frequently Asked Questions (B2B Buyer FAQ)

Answers to common structural, logistics, and technical engineering inquiries from commercial buyers and distributors.

Q: What makes Zenit’s custom OEM aluminum storm doors suitable for hurricane zones?
Our storm doors are engineered using heavy-duty 6063-T6 or 6061-T6 aluminum profiles with reinforced corner gussets and internal structural steel stiffeners. Combined with SGP laminated impact glass, our systems pass ASTM E1886/E1996 large missile impact testing and withstand design pressures exceeding DP70.
Q: What is the typical lead time for custom OEM/ODM extrusion dies and mass production?
Custom die design and sample extrusion take approximately 7 to 12 days. Once die prototypes are approved by the client, standard mass production lead times range from 20 to 30 days depending on the surface finish requirements (e.g., fluorocarbon coating vs. custom anodizing).
Q: How do thermal break storm doors compare to traditional solid aluminum doors?
Traditional solid aluminum transfers heat and cold rapidly, leading to condensation and thermal loss. Our thermal break storm doors utilize low-conductive polyamide PA66-GF25 structural strips that physically separate the interior and exterior aluminum profiles, reducing heat transfer by up to 60% and lowering building HVAC energy usage.
Q: Can you manufacture storm doors to meet custom architectural dimensions and hardware specs?
Yes. Over 90% of our production is fully customized OEM/ODM work. We accommodate custom height/width dimensions, arch shapes, divided lite grille layouts, specialized panic hardware for commercial doors, magnetic screen inserts, and custom brand packaging.
Q: What quality control measures are performed prior to sea container loading?
Our 35-inspector QC team performs a 100% assembly test fit on trial racks. Every batch undergoes air permeability, water tightness under high pressure, structural corner crimping strength checks, coating thickness measurement (Elcometer), and optical distortion scanning for glass panes.
Q: How do you protect glass and powder-coated profiles during ocean freight transport?
All profile surfaces are covered with protective anti-scratch film and foam edge corner guards. Finished doors are sealed in moisture-proof shrink wrap, placed on heavy-duty wooden or steel pallets, and packed in fully enclosed plywood crates with desiccant packs to prevent transit oxidation.
