Import Aluminum Alloy Glass Louver Windows — Buy in Bulk from Supplier in China

Calrton Doors And Windows Co., Ltd. manufactures aluminum alloy glass louver windows featuring adjustable-angle glass blades set within extruded aluminum frames. The frame profile employs thicker wall construction than standard louver systems to improve torsional rigidity and resistance to operability drift over repeated cycles. Glass panels are specified with UV-resistant treatment to reduce solar degradation of interior furnishings while maintaining visible light transmission. The supplier notes a pre-fabricated subframe for faster site installation, though exact frame alloy temper, blade dimensions, and glass thickness are not stated in the source data. These windows originate from Beijing, with the supplier located at K06, F#, Kaixuancheng, Beiyuan.

The louver mechanism permits blade angle adjustment, typically from 0 to 90 degrees or a restricted range to maintain weather protection when partially open. Standard aluminum louver window frames in China use 6063-T5 extrusions with wall thickness from 1.2 mm to 2.0 mm, while blades commonly measure 4 mm to 6 mm toughened glass. UV-resistant glass treatment usually involves pyrolytic or sputtered low-emissivity coatings, or interlayers in laminated configurations, though the supplier does not specify the exact technology or UV transmittance cut-off wavelength. The stronger profile referenced suggests the frame is engineered for mid-rise commercial or institutional duty rather than purely residential light-frame use. Buyers should confirm whether the system is tested to GB/T 8478 (aluminum windows and doors) or an equivalent standard for air permeability, water tightness, and wind resistance.

Applications include office buildings, educational facilities, healthcare renovation, and mixed-use developments where controlled natural ventilation and daylighting reduce mechanical HVAC load. The adjustable louver function suits climates with wide diurnal temperature swings, allowing night purging and daytime solar control. Calrton offers shipping under FOB or CIF terms and accepts L/C or T/T payment, though specific port, minimum order quantity, and unit pricing are absent from the source. Buyers should confirm blade quantity per window, maximum single-panel dimensions, and whether insect screens or security grilles are available as accessories. The lightweight aluminum construction reduces structural support requirements compared with steel systems, but engineering data for mullion span limits is not provided.

Calrton Doors And Windows Co., Ltd. is headquartered at K06, F#, Kaixuancheng, Beiyuan, Beijing 100101, China, placing it in the northern rather than the traditional southern China aluminum manufacturing cluster. The supplier holds an imported supplier tier and a harbor trust tier, indicating some level of platform verification but not equivalent to on-site factory audit or third-party quality system certification. Response rate and average response hours are both recorded at zero, signalling no tracked inquiry history and necessitating proactive follow-up by buyers to assess communication reliability.

The company profile does not disclose year of establishment, factory ownership (in-house extrusion versus assembly), number of employees, annual output, export volume, or named reference projects. No ISO 9001, ISO 14001, or product certificates are listed in the source data. The listing emphasises product features, UV glass treatment, and subframe installation convenience, but omits thermal performance data, acoustic ratings, and structural test reports. Buyers should request a company introduction, factory video, and quality management documentation before committing to volume orders.
