    Storefront Door Systems

    Standard Aluminum Storefront Doors

    The industry standard for commercial entrances. Narrow-stile and medium-stile aluminum frames with tempered safety glass. Available in clear anodized, dark bronze, and custom-painted finishes. Single, double, and vestibule configurations.

    Heavy Glass (All-Glass) Doors

    Frameless tempered glass doors with minimal hardware — patch fittings, pivot hinges, and pulls only. Creates a premium, transparent entrance for upscale retail, salons, galleries, and modern office spaces.

    ADA-Compliant Entry Systems

    Commercial entrances must meet Americans with Disabilities Act requirements for opening width, threshold height, closing speed, and hardware accessibility. We install and retrofit doors to full ADA compliance.

    Automatic and Power-Assisted Doors

    Sensor-activated sliding, swinging, and folding door systems for high-traffic entrances. Meets ADA requirements for hands-free access and provides ease of entry for customers carrying bags, using wheelchairs, or pushing strollers.

    Security Entrance Doors

    Reinforced frames, laminated or security glass, multi-point locks, and panic hardware for businesses requiring enhanced security — banks, jewelry stores, dispensaries, and high-value retail.

    Advance Measurement System

    Accurate measurements are the foundation of every successful glass and door installation. Our advance measurement system uses digital measuring technology to capture precise dimensions — eliminating the guesswork, return trips, and costly fabrication errors that come from manual measuring.

    How It Works

    • Digital capture— precise measurements of openings, frames, and glass dimensions using laser and digital tools
    • Documented records— every measurement is recorded digitally, creating a permanent reference for future repairs, replacements, or additions
    • Error reduction— digital measurement reduces fabrication errors to near zero, meaning fewer rejected panels and faster turnaround
    • Complex openings— curved, angled, and irregular openings measured accurately without physical templates

    Benefits for Business Owners

    • Faster quotes— digital data allows us to provide accurate estimates without multiple site visits
    • Faster fabrication— precise measurements mean glass and doors are cut right the first time
    • Reduced downtime— fewer fitting issues means fewer installation delays
    • Permanent records — your measurements are on file for future service calls, reorders, and property management

    Barriers

    Sneeze Guards and Protective Barriers

    Protect your customers and employees with professional sneeze guard and protective barrier installations. Required by health codes in food service environments and increasingly common in retail, office reception, and healthcare settings.

    Restaurant and Food Service

    • Counter-mounted sneeze guards for buffets, salad bars, deli counters, and cafeteria lines
    • Breath guards for point-of-sale areas and checkout counters
    • Meets health department requirements for food shield coverage and height

    Materials and Options

    • Tempered glass— most durable and professional option; scratch-resistant and easy to clean
    • Acrylic (plexiglass)— lighter weight, lower cost, suitable for temporary installations
    • Polycarbonate— impact-resistant, virtually unbreakable; best for high-traffic or rowdy environments
    • Clamp-mounted— attaches to existing countertops without drilling; removable
    • Ceiling-hung— suspended from above for a clean, floating appearance
    • Floor-standing— freestanding units for flexible placement

    Retail and Office

    • Checkout counter barriers— clear glass or acrylic dividers between staff and customers
    • Reception desk guards— professional-looking partitions that maintain communication while providing separation
    • Adjustable-height systems— accommodates standing and seated positions

    We evaluate your existing entrance, discuss your requirements (traffic volume, ADA compliance, security, aesthetics), and recommend the right door system.

    Step 2 — Digital Measurement

    Our advance measurement system captures every dimension digitally — ensuring accurate fabrication and eliminating field-fit issues.

    Step 3 — Fabrication and Sourcing

    Step 4 — Professional Installation

    Step 5 — Ongoing Service
