Hi, I'm Pu Yinlin
I'm the founder of YouPin Hardware — a trusted supplier of replacement hardware for older uPVC windows and doors, serving customers in Korea, Uzbekistan, and beyond.
Why I Started This Business
After years in the hardware industry, I noticed a common problem: finding quality replacement parts for old windows is often difficult, expensive, and time-consuming. I founded You Pin to solve this issue once and for all.
Today I work directly with homeowners, landlords and small businesses, handling every job myself — from the first message to the final check of the taps.
What I Offer
✓ High-quality handles, hinges, locks, limiters, and sealing strips
✓ Designed specifically for windows and doors aged 10-20+ years
✓ Factory-direct pricing with no middleman markup
✓ Fast and reliable shipping to Korea, Uzbekistan, and beyond
Quality Products
Every item is carefully selected and quality-checked before shipping to ensure it meets your expectations.
How I Work on Every Order
Clear Communication
I respond quickly, provide clear product details, and keep you updated throughout the ordering process.
Quality Over Speed
I take time to verify every order is correct — because the right part matters more than fast shipping.
