​Replacing old hardware is an important step in restoring or updating furniture. Whether you are upgrading to modern stainless-steel handles, installing new knobs, replacing a door stopper, or fitting handrail brackets, removing old components must be done with precision to protect the surface and structure of the furniture.

A door lock is a precision-built mechanism that ensures safety and daily convenience. When it fails to operate smoothly, identifying the cause and applying the right repair method can restore full function without replacing the entire system.

​Changing a door lock is an essential maintenance skill for both residential and commercial property owners. Whether you’re upgrading for security, replacing a worn mechanism, or matching new hardware aesthetics, the process requires careful measurement, alignment, and installation technique.

A knob is a compact control element that allows the user to grasp, pull, or rotate a surface with precision. It serves both as a functional and decorative component across furniture, architectural fixtures, and equipment design.

Whether you’re upgrading an existing kitchen or assembling new furniture, this guide explains the process step-by-step and explores the key factors to consider for a durable, attractive installation.

​A stainless steel door knob is engineered for precision, durability, and aesthetic value. Whether made from SUS304 or SUS316 stainless steel, it resists corrosion and retains a polished appearance for years. However, frequent use, vibration, and environmental stress can still loosen internal components.

A floor-mounted door stopper is one of the most reliable ways to protect walls, glass panels, and door hardware from repeated impact. It ensures the door stops at a precise point, absorbing force safely while maintaining the aesthetic flow of the space.

A stainless-steel door stopper is a small but vital component that protects doors, walls, and hardware from impact. When a stopper becomes loose, misaligned, or fails to absorb shock effectively, it can cause noise, surface damage, or even safety hazards.

​A door stopper may look like a simple accessory, but it plays a crucial role in protecting both the door and surrounding structures from impact damage. For high-end architectural projects and modern interiors, stainless steel door stoppers made from SUS304 or SUS316 provide long-lasting durability, precision, and aesthetic consistency with other metal fittings.

Sliding door systems are designed with precision, and while many materials can theoretically be mounted to a track, not all doors are suitable for the same type of hardware. Our stainless steel sliding door hardware is engineered specifically for glass doors, ensuring strength, silence, and safety in both residential and commercial environments.

A loose handle on a sliding glass door is a small issue that can quickly become a serious one if left unaddressed. Glass door handles—especially stainless steel recessed or through-bolt types—require precise installation and maintenance to ensure both safety and smooth operation.

​The spacing between handrail brackets is one of the most critical details in ensuring both structural safety and visual consistency. The distance between each bracket determines how much weight the handrail can bear, how it feels to the touch, and how well it integrates with the overall design of a staircase or corridor.
