Engineered specifically to fulfill Houston’s stringent commercial building standards, thermal performance mandates, and extreme wind-load resistance requirements.
Established in 2003, Steelwar Entry Systems Co., Ltd. operates a large-scale 40,000 m² manufacturing plant specializing in high-security exterior entry doors and heavy-duty architectural lift-sliding doors. With 21 years of continuous industry experience and 9 years of global export capabilities, the company generates $35 million in annual export turnover. Steelwar focuses on key markets across North America, the Middle East, and Eastern Europe, primarily supplying building material distributors, security door stockists, and commercial construction contractors.
Supported by a solid trade background and a network of 1,100 supply chain partners, Steelwar maintains strict product reliability. Quality control is managed by a team of 50 QC specialists who execute dynamic impact resistance testing, automated frame tolerance checks, and corrosion-resistant coating audits. The company's engineering strength is backed by 75 R&D engineers who introduced 230 new product models last year. Custom options include ballistic steel cores, multi-point smart lock integration, customized RAL color finishes, and bespoke frame depths.

Houston experiences over 200 sunny days per year with summer temperatures routinely exceeding 95°F combined with high humidity. Uninsulated glass openings act as thermal bridges. Our lift-sliding systems incorporate multi-chamber polyamide thermal breaks and spectrally selective Low-E coatings, maintaining Solar Heat Gain Coefficients (SHGC) below 0.20 to drastically lower HVAC operational overhead for commercial and high-density residential developments.
Located near the Gulf of Mexico, the Greater Houston region (including Harris, Fort Bend, and Brazoria counties) is susceptible to severe thunderstorms and hurricane-force winds. Steelwar's heavy-duty lift-and-slide hardware seals panels vertically against multi-stage EPDM weather-stripping when lowered, achieving high water resistance ratings (up to 750 Pa / 15 PSF equivalent) and wind pressure endurance up to Design Pressure (DP) ±80 PSF.
Houston’s industrial refining atmosphere combined with coastal humidity subjects metal architectural components to accelerated oxidation. All Steelwar lift-sliding doors destined for Texas markets undergo Qualicoat Class 2 fluorocarbon electrostatic powder coating or 25-micron anodization, surpassing 3,000-hour salt spray endurance audits (ASTM B117 standard) for structural longevity.
Unlike conventional sliding doors that drag across fixed brush gaskets (causing friction, seal degradation, and air leakage), a Lift-Sliding Door utilizes specialized gear mechanisms. When the handle is turned 180 degrees, the entire door panel lifts 6mm off the track, supported by heavy-duty stainless steel tandem rollers. This allows massive panels (up to 600 kg / 1,320 lbs per sash) to glide effortlessly. When closed, the panel drops onto the frame perimeter, forming a compressed airtight and watertight seal that completely satisfies International Building Code (IBC) and Texas Energy Codes.
