Our five advantages are your professional choice

1. LY profile section is multi-cavity structure , and the design is scientific and reasonable ,thus effectively improving the heat preservation ,heat insulation and sound insulation performance of doors and windws.
2. LY profile has realized the integrated production of rubber strip and profile , which makes the connection between sealing rubber strip and profile firm and does not fall off , and the joint of rubber strip does not break,thus saving labor , time and labor cost when processing doors and windws.
3. Apply advanced diversified surface treatment technologies and treatment technologies of colorful surface design such as two-tone co-extrusion , wrie drawing , embossing and laminating . With advancing design concept , beautiful and utility finished products and smooth .
4. In the formula of LY profile , all the high-quality green environmental protection raw materials which are non-toxic , tasteless , harmless and pollution-free are selected , and the flame retardant is reasonably added , so that the profile has the safety of health , safety , environmental protection , non-volatilization of harmful gases,non-flammability , self-extinguishing and non-conductivity .
5. LY profile adopts high-quality raw materials and international leading production technology , which can make doors and windows not aging ,embrittlement and deformation in the harsh environment of cold , sun exposure , humidity , sand and chemical pollution , and the service life of doors and windowa can reach more than 50 years.
