Our Exterior Door Collection
Steel Exterior Doors
Our Steel Exterior Doors are built entirely from heavy-gauge, dent-resistant galvanized steel, ideal for residential and commercial projects that prioritize security and cost control. They deliver superior structural strength and reliable performance, making them an economical solution for high-traffic applications.
Screen Doors
UWG's engineered-grade screen doors feature premium wood-composite framing and a high-tension, tear-resistant mesh — including retractable screen door options — adding ventilation and comfort as a functional upgrade to any entry system, helping builders enhance livability and product appeal.
Fiberglass Exterior Doors
A low-maintenance, high-durability entry door solution that combines outstanding weather resistance, consistent finish quality, and a wide range of glass configurations — helping builders lower long-term maintenance costs.
Patio Doors
With expansive natural light and a seamless indoor-outdoor connection, superior air-tightness effectively lowers whole-building energy consumption — making these sliding patio doors an easy pass for North American energy-efficiency assessments.
Exterior French Doors
UWG's exterior french doors come standard with high-strength, double-pane tempered insulated glass and a fully wrapped weather-sealing gasket — delivering exceptional natural light while ensuring the whole home meets engineering-grade standards for insulation, soundproofing, and impact safety.
Whether your residential project needs high-volume standard exterior doors, or custom entry doors with complex sidelite and transom configurations, just send us your door schedule, project drawings, or spec list. We'll provide a complete, no-middleman factory wholesale quote, delivered DDP straight to your jobsite.
Exterior Door Configurations
Beyond the standard single door, we offer an extensive range of entry door configurations. Whether it's a grand double door, front entry doors with sidelites, or entry door systems with both sidelites and transoms, UWG supports precision factory prefabrication to ensure fast on-site installation.

Double Entry Doors
Creates a more visually striking home entrance with a wider opening and a more upscale appearance — ideal for custom homes and high-value residential projects.
In terms of cost, double door systems require a wider opening, typically a larger Rough Opening, and the overall system cost increases accordingly with the frame, hardware, and installation labor — but the payoff is a symmetrical, prestigious front-entry facade.
Entry Doors with Sidelites
Sidelites add natural light and architectural depth, helping builders create a more attractive home facade while maintaining entry security and overall performance.
This is a highly cost-effective way to upscale the entrance — compared to double doors, it keeps the overall entry system budget in check while dramatically improving natural light and openness in the foyer.
Entry Doors with Sidelites and Transom
Designed for high-end residential entrances, the combination of sidelites and a transom enhances natural light, proportion, and architectural presence, creating a showcase-worthy Premium Entry.
While combining a transom with sidelites increases material and shipping costs, it significantly elongates the building's vertical visual lines — the go-to choice for a truly luxury home facade.

Fiberglass vs. Steel Doors: Climate-Matched Material Guidance
In terms of material, UWG primarily offers Fiberglass and Steel exterior doors. Both materials perform well overall in weather resistance, and we can help builders scientifically match the most suitable surface and core material based on the project's geographic climate.
| Specs | Steel Exterior Doors | Fiberglass Exterior Doors |
|---|---|---|
| Best Climate |
Regions with extreme temperature swings and severe cold Withstands harsh northern winters and snow Commercial/residential projects needing high security |
High-humidity and coastal salt-spray regions 100% immune to sea-salt spray and acid rain Rainy, extremely humid southern climates High-end custom residential projects |
| Engineering |
Metal exterior doors built from heavy-gauge galvanized steel High strength and excellent impact resistance Heavy, thickened steel panels offer excellent pry resistance Polyurethane foam core improves R-value |
Zero warping and structural-grade corrosion resistance Composite edge construction that will never rot Completely solves water absorption, swelling, and cracking issues |
| Maintenance |
Low maintenance cost Comes standard with a factory-applied corrosion- and weather-resistant primer Well-suited for large-volume, standardized project delivery |
Lifetime zero maintenance Can be embossed with an extremely realistic, upscale wood-grain texture No need for periodic repainting |
| Fire Rating | Supported | Supported |
| Project Cost | Economical, proven, top choice for large volumes | Mid-to-high-end homes, cost-effective wood-look alternative |
In short: if your project prioritizes maximum cost-effectiveness, high impact resistance and security, or is located in an extremely cold northern climate, Steel is the safest bet. If your project faces coastal humidity and corrosion, demands zero long-term maintenance, or wants a premium wood-grain look, Fiberglass is the better value.

Safety-Compliant Glass & Structural Combinations
Exterior Door Performance: Weatherproofing & Water Management
Our high-precision prehung exterior doors not only shorten on-site construction time but also feature a factory-integrated weatherproofing system that fundamentally blocks out harsh outdoor conditions. Every unit ships standard with a heavy-duty exterior door threshold and a high-resilience exterior door sweep that seals tightly against the threshold — keeping out driving rain and cold drafts even under high wind pressure. Every door style passes rigorous air- and water-tightness testing before leaving the factory, meeting the standards required for large-volume project delivery.
We also offer fire-rated exterior doors that comply with North American safety codes, meeting 20-minute fire ratings with a 20-min UL fire label on each sla
More Secure Exterior Doors: Security & Locking Systems
UWG's exterior doors are structurally engineered around exceptional forced-entry resistance. Every exterior door is precision pre-bored at the factory to perfectly support advanced multi-point locking systems — not only boosting anti-pry security but also preventing warping caused by long-term, uneven stress on the slab.

Exterior Door Sourcing Guide for Builder
Fiberglass doors generally offer better durability, energy efficiency, and design flexibility, while steel doors are more affordable upfront and provide superior security.
Exterior Door Sourcing FAQ
In North America, a standard residential exterior door (a "3068" door) measures 36" × 80" with a 1-3/4" thickness, requiring a standard Rough Opening of 38" × 82.5".
For more details, click: Exterior Door Sizing & Specifications
Generally, you can use the following rule of thumb:
Rough Opening Width = Door Slab Width + 2 Inches
Rough Opening Height = Door Slab Height + 2-1/2 Inches
Example: For a standard 30" x 80" door, the Rough Opening is typically 32" x 82.5".
If you're still unsure about measurements, feel free to contact us anytime — we can help you calculate precise dimensions.
If you're looking for the best value, top-tier security, or your project is in a cold northern climate, our high-strength Steel Doors are a proven, budget-friendly choice.
If you want an authentic wood-grain look, your project is in a rainy, high-humidity coastal region, or you want a wider range of color customization, our rust-proof, premium-feel Fiberglass Doors are your best option.

Absolutely. In addition to standard single entry doors, we also offer custom wide double doors and entry door systems with single or double sidelites. Before leaving the factory, each complete door system undergoes precise frame alignment and inspection by our team. This helps ensure excellent structural stability, air tightness, and water resistance, even in wide-opening and heavy-duty configurations.
Based on a 30" × 80" door, a standard 40HQ container holds approximately:
- 896 pcs of door slabs only
- 234 sets of prehung doors
- 630 sets of knock-down doors
