QWhat customized options are available for WANJIA sliding doors?
We offer complete customization including profile colors, frame sizes, opening configurations, glass types (double/triple/Low-E), and hardware choices such as premium German imported fittings.
QHow do your thermal break profiles improve energy efficiency?
Our thermal break aluminum profiles separate the inner and outer metal frames with reinforced insulating strips, preventing heat transfer and significantly lowering heating and cooling costs.
QWhat is the watertight performance of these sliding doors?
Our doors feature multi-layer EPDM rubber sealing strips, hidden isobaric drainage channels, and waterproof corner plugs, providing high watertight resistance certified up to over 500Pa.
QCan these sliding doors provide effective sound insulation?
Yes. By combining double or triple insulated glass with argon gas filling and Low-E coatings, WANJIA doors dramatically reduce external noise for a quiet indoor atmosphere.
QWhat certifications and quality inspections do WANJIA products hold?
WANJIA operates under strict factory management tested by ISO, SGS, and TUV. Our products comply with international energy efficiency and safety standards for seamless project approval.
QHow are products packaged to ensure safe transport during shipping?
We use three layers of protective packaging materials (protective film, corner guards, and sturdy wooden crates/boxes) along with DDP logistics tracking to guarantee products arrive in perfect condition.
