Architectural projects in Greater Houston—ranging from luxury estates in River Oaks and Memorial to modern urban infills in The Heights and Montrose—face an extraordinary convergence of climatic stresses. Houston operates under IECC Climate Zone 2A, characterized by high annual ambient temperatures, extreme solar radiation indexes, intense relative humidity, and severe Gulf Coast weather events.
Traditional non-thermally broken metal window frames pose significant operational risks in Texas AC-dominated environments. When internal air conditioning lowers interior frame temperatures while exterior relative humidity breaches 85%, uninsulated metal sashes drop below dew point, causing severe internal condensation, wall cavity mold growth, and premature interior finish degradation.
Our direct-export steel window assemblies utilize advanced Polyamide (PA66) glass-fiber reinforced thermal breaks. This structural barrier mechanically separates exterior and interior steel profiles, interrupting conductive thermal bridging while maintaining structural tensile strength under heavy glass loads.
Comprehensive engineering benchmarks comparing export-grade thermally broken steel sashes against conventional architectural window framing materials.

Our custom steel window systems are manufactured to exact field templates, allowing seamless architectural integration across Houston's distinct neighborhood typologies.
High-end residential projects in River Oaks demand sweeping minimalist glass walls and narrow-profile French doors without sacrificing thermal comfort. Our custom true-divided-lite steel sashes replicate timeless historical profiles while incorporating modern warm-edge insulated glass units.
Modern residential architecture in Houston’s Historic Heights relies on high-contrast matte black steel windows to frame urban interior spaces. Our thermal-break sashes provide structural rigidity for floor-to-ceiling glass grids that maximize natural light during humid summer months.
Properties located along the Galveston Bay coastal corridor require rigorous structural windload mitigation. Our hurricane-impact steel windows incorporate multi-layer laminated glass and heavy-duty locking sashes engineered to meet strict Texas Coast DP70+ design pressures.
Founded on an uncompromising commitment to craftsmanship, our manufacturing operations control every stage of fabrication, welding, glazing, and finishing under one roof. Operating since 1973, we bridge decades of custom shop experience with cutting-edge export logistics.
Unlike regional distributors who outsource frame assembly to third-party plants, our dedicated engineering shop builds every window unit to exact 1/8-inch field measurements. This single-roof operational control guarantees that shop drawings, thermal calculations, profile cuts, structural welds, and crating are strictly audited before departure to the Port of Houston.
Cutting, TIG/MIG welding, glass hand-off, and hardware installation executed in an ISO-audited facility.
Arched tops, trapezoids, radius bow assemblies, and historical true divided lite muntin patterns built to drawing.
Heavy-duty sea-freight wooden crates with moisture-vapor barriers ensure damage-free arrival at job sites in Texas.
Essential engineering and logistical guidance for builders, structural engineers, architects, and luxury homeowners sourcing steel window systems for Texas projects.
Houston experiences severe high humidity (often exceeding 85% RH) combined with summer outdoor temperatures over 100°F. In air-conditioned buildings set to 70°F, non-thermally broken steel frames rapidly transfer heat and drop below the ambient dew point. This causes heavy internal frame sweat (condensation), leading to water damage on drywall, interior wall cavity rot, and mold growth. Our thermal break technology uses high-strength polyamide isolators to separate interior and exterior steel sashes, raising interior surface temperatures above the dew point and eliminating sweating.
Steel possesses a Modulus of Elasticity (E = 29,000 ksi) three times greater than extruded aluminum and nearly eighteen times higher than timber. This structural density allows steel window frames to achieve Design Pressure (DP) ratings of DP60 to DP100+ while maintaining sightline profiles as thin as 1-1/8 inches. Under ASCE 7-16 wind load standards for Harris County, our structural steel assemblies prevent frame deflection and seal fatigue during 140+ mph windstorm events.
To resist salt-spray oxidation in regions near Galveston Bay and coastal Texas, our steel profiles undergo a multi-layer surface treatment protocol compliant with ISO 12944 C5-M marine anti-corrosion standards. This includes: (1) Degreasing and chemical pickling, (2) Hot-dip galvanizing (HDG) zinc coating per ASTM A123, (3) Epoxy e-coating primer, and (4) Architectural fluorocarbon PVDF powder coating bake. This multi-stage duplex coating guarantees a maintenance-free lifespan exceeding 30 to 50 years.
Yes. Because every sash and frame is cut, welded, and hand-finished to order, we build to exact 1/8-inch field measurements. We routinely fabricate historic arched tops, trapezoidal clerestories, radius bow windows, custom true divided light (TDL) grids, and simulated divided light (SDL) muntin patterns matching historic preservation guidelines in Houston neighborhoods like River Oaks and The Heights.
Export orders bound for Houston are encased in fully enclosed, IPPC-certified fumigated hardwood crates with internal shock-absorbing foam lining and waterproof shrink-wrapping. Glass units are packed with protective corner guards and rubber spacers to withstand ocean container transport and regional flatbed trucking directly to your Houston job site.
All fabricated structural steel profiles are backed by a comprehensive manufacturer warranty covering frame structural integrity and anti-corrosion performance. Double and triple insulated glass units carry a 10-year seal failure warranty against argon gas dissipation and internal fogging. Hardware components and weather-stripping are covered under a written 5-year replacement guarantee.
