Engineered to international structural standards with certified thermal break performance and high-tensile alloy frames.
A premier OEM/ODM manufacturing hub delivering structural excellence across global commercial and high-end residential developments.
Founded in 2015, Chengdu Zenit Window & Door Co., Ltd. operates a state-of-the-art 25,000-square-meter manufacturing facility. Backed by 11 years of deep industry expertise and 8 years of specialized global trade experience, our annual export turnover reaches $26 million. Our core market footprints encompass North America, Australia, and Western Europe, supplying tier-one residential home builders, architectural contractors, and multi-national building material distributors.
Addressing high humidity, thermal bridge losses, structural airtightness, and architectural privacy in modern commercial projects.
Bathroom environments represent demanding micro-climates high relative humidity, chemical cleaning agent exposure, and persistent steam condensate. Zenit’s custom OEM bathroom windows utilize 6063-T5 high-grade aluminum profiles treated with anodization (up to 25 microns) or PVDF fluorocarbon coatings, guaranteeing salt spray resistance past 3000 hours without profile degradation.
Achieving optimal light transmission while guaranteeing visual privacy is paramount in modern hospitality and multi-family design. OEM options include obscure frosted glass, textured reed patterns, and switchable Smart Polymer Dispersed Liquid Crystal (PDLC) privacy glass, allowing instant transition between clear and opaque states via smart automation systems.
Preventing thermal transfer and indoor surface condensation is critical. Utilizing continuous Polyamide PA66 nylon thermal barriers inserted into dual-cavity profiles, Zenit aluminum bathroom windows achieve impressive U-factors down to 0.28 BTU/h·ft²·°F, eliminating thermal bridging and mold spores on interior walls.
Quality control is strictly managed by our team of 35 certified inspectors who execute multi-phase air permeability testing (ASTM E283), water tightness checks (ASTM E331 up to 450 Pa static pressure), and frame corner joint structural strength evaluations. Backed by over 600 qualified supply chain partners, Zenit delivers turnkey customization options including thermal break extrusions, custom anodized and powder-coated finishes, and triple-pane soundproof laminated glazing systems.
Comprehensive technical parameters customized for project-level procurement and international building codes.
