Who We Are

StrongLite manufactures high-performance architectural steel windows and doors for residential and commercial projects throughout the United States and Canada. Our precision-engineered, thermally broken steel systems combine exceptionally narrow sightlines with advanced thermal, structural and weather performance. Our leadership team brings decades of experience in technical design, engineering and international manufacturing. StrongLite products are tested and certified to demanding North American performance standards, including NFRC, NAFS and TDI requirements. We combine modern engineering and manufacturing with the attention to detail and craftsmanship that exceptional architecture demands.

What we do

StrongLite designs and manufactures high-performance architectural steel window and door systems for distinctive residential and commercial projects. Our thermally broken systems combine exceptionally narrow sightlines with advanced glazing, structural performance and weather resistance. From fixed and operable windows to swing, sliding, bifold and pivot doors, we work with architects, builders and developers to translate demanding designs into carefully engineered, custom-made fenestration.

Our Approach

StrongLite works closely with customers and project teams from initial consultation through design development, production, delivery, installation coordination and after-sales support. Our goal is to make the process clear and dependable, providing responsive communication and technical assistance as architectural plans are developed into finished steel window and door systems. We look forward to bringing that same commitment to service and support to your next project.

Our Standards

  • Thermally broken steel window and door systems
  • Sightlines as narrow as 12 mm (1/2″)
  • Precision-fabricated steel frames
  • Durable zinc-galvanized steel construction
  • Multi-stage weather sealing
  • Insulated dual- and triple-pane glazing options
  • Low-E and solar-control glazing options
  • NFRC, NAFS and TDI certified systems

Energy Efficiency

StrongLite thermally broken steel systems are designed to combine narrow sightlines with high levels of thermal performance. Insulated glazing, Low-E and solar-control coatings, thermally isolated frames and multi-stage weather seals work together to reduce heat transfer and help control air and water infiltration. These technologies allow expansive areas of glass and slender steel profiles to perform efficiently across a wide range of climates.

Safety & Security

StrongLite steel windows and doors combine the inherent strength of steel with robust frames, quality hardware and multi-point locking systems. Impact-resistant glazing and additional security options can be incorporated where project requirements demand them. Together, these features provide a strong, secure building envelope without compromising the slender profiles and architectural character of the system.

Our Service

StrongLite works closely with architects, builders and project teams from initial design through fabrication and delivery. We focus on clear communication, accurate technical information and careful coordination so that each custom window and door package meets the architectural and performance requirements of the project. We will:

  • Communicate clearly and accurately throughout the project.
  • Assist with product selection and technical requirements.
  • Provide detailed CAD drawings for review and approval.
  • Confirm dimensions, configurations and order details in writing.
  • Coordinate production and delivery with the project schedule.
  • Support our products with technical assistance and warranty coverage.

Enduring Value

StrongLite steel windows and doors are designed for lasting architectural and functional value. Durable galvanized steel construction, high-performance finishes, quality glazing and carefully engineered hardware provide long-term performance with minimal maintenance. The inherent strength of steel also allows exceptionally slender profiles that retain their architectural character over time. Combined with thermal performance and carefully controlled fabrication, these qualities make StrongLite systems a lasting part of the architecture rather than simply another building component.

Yes. StrongLite works directly with architects, contractors, developers and project owners, and we also work with qualified representatives and dealers in some markets. Our team can assist with product selection, technical requirements, drawings, ordering and delivery coordination throughout the project.

Yes. We can review project requirements and help identify window and door configurations, glazing, hardware and other options that meet the architectural and performance goals while remaining mindful of the project budget. Where appropriate, we can suggest alternatives that preserve the design intent while reducing cost.

StrongLite products are backed by warranty coverage for the steel system, finishes and glazing, subject to the terms applicable to each product and project. Please see our full warranty for current coverage, conditions and exclusions.See full warranty

StrongLite products are carefully protected for transport using purpose-built packaging appropriate to the size and configuration of the order. Large shipments are typically secured for container transport, with delivery coordinated to the project location. Our team works with the contractor or project team in advance to coordinate shipping, unloading requirements and delivery logistics.

Production and delivery schedules vary with project size, complexity and shipping requirements. Typical lead times are approximately 12–15 weeks following final drawing approval, with some projects possible in as little as 8–12 weeks. Your project team will provide an estimated schedule and keep you informed of significant changes during production.
