Door Handle Solutions: Materials That Master Every Environment
The procurement landscape demands not just a good door handle, but the right one for the job. Our multi-material capability is our core strength, covering five distinct alloys and polymers: Stainless Steel for ultimate durability, Brass for luxury and hygiene, Zinc Alloy for design versatility, Aluminum Alloy for lightweight resilience, and Nylon for mandated fire safety. GMB comprehensive offering ensures that whether your project is a coastal commercial tower or a top-tier medical facility, GMB SINO provides the optimal component for long-term TCO optimization and regulatory certainty.
Product Advantages
We deliver certified quality, not just promises.
Fire Safety & Compliance
Our specialized, fire-resistant Nylon door handle systems are explicitly certified to European EN12209 standards.
Corrosion Resistance & TCO
The Stainless Steel series is the durable cornerstone for high-traffic and harsh environments (e.g., coastal). Its superior resistance to rust and wear significantly lowers maintenance costs and optimizes the Total Cost of Ownership (TCO).
Luxury, Hygiene, and Longevity
Brass door handles offer timeless elegance and a lifespan of up to 100 years. Crucially, its natural antibacterial properties make it the ideal, sustainable choice for healthcare and aged care environments.
