Rolling steel doors are no longer one-size-fits-all. Today, they're highly configurable systems designed to meet specific performance, environmental, and aesthetic requirements. For professional door dealers and installers who may be new to rolling steel, understanding these customization options is key to specifying the right door for the application and setting projects up for long-term success.
This guide walks you through the most common rolling steel customization options, why they matter, and how ASTA America supports flexible, application-driven solutions without overcomplicating the process.
Why Customization Matters in Rolling Steel Doors
Every opening has its own challenges. Environmental exposure, security needs, usage frequency, and design intent all influence door selection. Customization allows rolling steel doors to be tailored to the application rather than forcing the application to adapt to a standard product.
From material selection to curtain design, these options help dealers deliver doors that perform as expected while meeting code, durability, and visual requirements.
Curtain Materials: Matching the Door to the Environment
Galvanized Steel Curtains
Galvanized steel remains the most common curtain material due to its durability and cost-effectiveness. ASTA offers galvanized steel curtains in standard finishes, as well as pre-painted and powder-coated options for projects that require enhanced corrosion resistance or a specific appearance.
Common applications include:
- Warehouses and distribution centers
- Manufacturing facilities
- Storage and service areas
Stainless Steel Curtains
Stainless steel provides excellent resistance to rust, staining, and chemical exposure, and it's often specified where cleanliness, moisture resistance, or a refined appearance is required.
Typical applications include:
- Food and beverage facilities
- Coastal or high-humidity environments
- Architectural projects with exposed doors
Aluminum Curtains
Aluminum rolling steel doors offer a lightweight, low-maintenance solution with natural corrosion resistance. These doors are well-suited for applications where weight or frequent cycling is a concern.
Common uses include:
- Retail and mixed-use buildings
- Parking structures
- Interior commercial openings
Insulated vs. Non-Insulated Curtains
Non-Insulated Rolling Steel Doors
Non-insulated curtains are often selected for interior openings or environments where thermal performance is not a priority. They provide security and durability with a simpler construction and lower initial cost.
Insulated Rolling Steel Doors
Insulated curtains feature a foam-filled polyurethane core that improves thermal performance and reduces noise transmission. These doors, such as the ASTA 600 Series, are commonly used in temperature-controlled or noise-sensitive environments.
Benefits of insulated curtains include:
- Improved energy efficiency (see DASMA technical sheet #163)
- Reduced sound transmission
- Added rigidity for high-cycle applications
Finishes and Powder-Coating Options
ASTA offers a virtually unlimited range of powder-coated color options to align rolling steel doors with architectural designs, brand standards, or surrounding materials. Powder coating not only enhances appearance but also adds an extra layer of protection against corrosion and wear.
This option is frequently specified for:
- Retail storefronts
- Public and government facilities
- Visible exterior openings
Vision Panels
Vision panels, also referred to as lites, allow natural light and visibility while maintaining security. These panels are strategically placed within the curtain to support operational visibility without compromising door performance.
Common applications include:
- Warehouses and loading areas
- Parking decks
- Retail and service counters
Perforated and Fenestrated Slats
Perforated slats provide airflow, visibility, and light penetration while still acting as a secure barrier. Fenestrated designs are especially popular in applications where transparency and ventilation are required.
Typical use cases include:
- Parking garages
- Retail storefront security closures
- Mixed-use developments
tailored solutions for every project
Customization goes beyond selecting finishes and materials. ASTA supports door dealers with engineering resources designed to simplify specification and installation, such as CAD drawings, BIM files, and engineering support. Whether the goal is maximizing curb appeal, increasing visibility, or enhancing thermal performance, rolling steel doors can be fully customized to meet operational and architectural specifications.
