In America, when it comes to roofing materials, asphalt shingles are so commonly used that they have become synonymous with roofing materials.
In our country, the evaluation of shingles as roofing materials has become unwavering after more than 40 years. Our company has developed a shingle based on fiberglass non-woven fabric, aiming for further quality improvement. Compared to conventional products, it excels in durability and weather resistance.
