Steel Main Structure: Premium cold-rolled steel plate forming the door's main framework — structurally solid and durable, impact-resistant and deformation-resistant, adapted to high-frequency commercial use and pedestrian traffic impact
Steel-Wood / Wrought Iron Composite: Steel-wood composite combining steel strength with wood texture; wrought iron craftsmanship delivering unique decorative effects on the door face — two options meeting different scenario aesthetic requirements
Powder Coated Smooth Surface: Electrostatic powder coating process — smooth, refined finish with uniform, lasting colour, wear-resistant, scratch-resistant, and easy to clean, simplifying daily maintenance in commercial environments
Waterproof Sealing System: Door structure + weatherstripping + surface coating triple waterproof design — effectively resisting humid environment erosion, confidently usable in bathrooms, basements, and coastal areas
Stainless Steel Screen Netting: High-density stainless steel wire woven mesh — preventing insects and theft while maintaining ventilation, corrosion-resistant and rust-free, suitable for commercial spaces requiring airflow
Glass Door-Type Design: Door face configured with glass viewing windows / glass panels — introducing natural light to enhance space brightness while enabling observation of exterior conditions, improving both security awareness and convenience
