Frosted glass products deliver privacy and natural light diffusion for offices, bathrooms, partition systems, and contemporary architectural designs. Available in multiple opacity levels and custom cut sizes for direct integration into project specifications.

Smart Door Locking Systems

Vanlake supplies smart door locking systems compatible with residential and commercial door configurations. Options include keypad, card reader, and remote access models designed for security-critical applications in hospitality, office, and residential developments.

EPDM Rubber Sealing Solutions

EPDM rubber strips are used for insulation and weatherproofing in door and window assemblies. They improve thermal efficiency, reduce air infiltration, and extend the service life of framing systems across all climate types.

Why Buyers Choose Vanlake

Consistent supply, not just competitive pricing. Buyers choose Vanlake because our manufacturing process is built for repeatability, the same product specification, finish tolerances, and packaging on every order, whether it's a 50-unit sample run or a 10,000-unit project consignment.

Single-source procurement. Vanlake covers the full scope of architectural openings, windows, doors, glass, curtain walls, and sealing systems, reducing the number of suppliers a procurement team needs to manage.

Custom manufacturing without minimum complexity. OEM and ODM production is available across all product categories. Buyers can specify dimensions, finishes, hardware, glazing type, and thermal performance requirements without the typical lead time penalties of bespoke manufacturing.

Competitive wholesale pricing. Our factory-direct model eliminates trading margins, providing importers and project buyers with pricing that supports healthy downstream margins.

International project experience. Vanlake has supplied architectural products to projects across the Middle East, Africa, and Southeast Asia, with knowledge of regional building codes, climate requirements, and logistics constraints.

Technical Features & Material Advantages

• Frosted glass for privacy and light control — available in acid-etched and sandblasted finishes with consistent opacity across batch production
• EPDM triple-seal weatherproofing — air and water infiltration resistance tested to international standards
• Smart locking compatibility — electronic and mechanical hardware options with multi-point locking for enhanced security performance
