Since its founding in 1990, Lianheqiang has traversed 37 years of industry development, deeply cultivating the architectural doors, windows, and curtain wall sealing sector. With meticulous craftsmanship, it refines every sealant strip, letting time bear witness to its unwavering quality.

After more than thirty years of rigorous field testing, Hong Kong’s large‑scale residential doors and windows, as well as curtain wall projects at major domestic airports, have consistently relied on “Lianhe Strong Sealant Strips,” with many installations performing reliably for 25 to 30 years. Enduring continuous exposure to sun, rain, and fluctuating temperatures, these products maintain stable sealing performance and resist aging and deformation. Countless long‑term, real‑world applications vividly demonstrate that Lianhe Strong Sealant products offer exceptional weather resistance and durability, standing up to the test of time and withstanding the demanding conditions of diverse architectural environments over extended periods.
