We Supply High-performance Custom Door Hardware Worldwide

Our products meet UL, CE, and ANSI/BHMA standards for global projects.
As a Door Hardware Supplier. We supply premium Custom door hardware solutions including hinges, handles, locks, closers & stops. Engineered for durability in commercial buildings, hotels, and high-traffic areas. 
Stainless Steel Door Hinge
Our hinges feature permanent, factory-lubricated bearings that never need oiling, eliminating sticky operation. Precision-engineered components prevent metal-on-metal friction, guaranteeing quiet performance even after years of use.
Stainless Steel Door Handles
Our handles are engineered with reinforced internal fastening systems to prevent wobble and detachment. Applied with multi-layer, wear-resistant coatings (PVD or powder-coated), they resist scratches, corrosion, and UV fading, maintaining their elegance through years of high-frequency use.
Stainless Steel Door Stopper
Our stoppers are designed with soft, non-marking tips (rubber or polyurethane) to protect walls and finishes. Wide, anti-slip bases or robust flange designs provide maximum stability on various floor types, preventing movement under force and offering dependable door control.
Lock body
Constructed from heavy-gauge steel or reinforced zinc alloy, our lock bodies offer exceptional strength to resist forced entry. Precision-machined components and adjustable strike plates ensure perfect alignment with the door and frame, eliminating binding and ensuring consistent, trouble-free latching.
Lock cylinder
Featuring anti-pick pins, drill-resistant steel inserts, and reinforced keyways, our cylinders provide superior physical defense. Manufactured from high-strength brass or nickel-silver alloys, they prevent key breakage and ensure smooth, reliable operation over an extended lifespan.

Picking out the right rubber door stopper might not seem like a big deal at first, but honestly, it can really make a difference in how your home looks and functions. As John Smith from Home Safety Innovations puts it, “A good door stopper isn’t just about keeping doors in check; it actually adds some character to your space.” So, yeah, it’s worth taking your time and thinking it through. There’s actually quite a bit to consider. First off, material quality matters—rubber tends to last longer and handle wear and tear better than some other options. Then there’s the look—things like the White Rubber Door Stopper can really complement your home’s decor. While it’s super important for the stopper to do its job, you don’t wanna forget about how it looks either. A lot of people rush their choices and end up disappointed. Remember, the main goal of a door stopper is to protect your walls and stay stable—so think about what you actually need before you buy. Making an informed decision now can save you from regrets later, and it’ll make sure your purchase really pays off.”
