Seeton has a state-of-art machine designed to improve the efficiency of sticking two layers. And we have the technology of double strips and cutting-edge technology of environment isolation.

Between two types of granule (dyeing granule and sintered granule), Seeton takes sintered granule as its raw material, which lays a foundation for better quality asphalt shingle.

l Unique sanding system

We choose Triangular coarse sand which achieves a better roof effect than normal sand.

l Unique asphalt

The raw material of high-quality modified asphalt makes Seeton asphalts shingle more stable and solve the problems like flowing at high temperature and cracking at low temperature.

The fiberglass melt we use, which is the same as Owens Corning, can prolong the life span of asphalt shingle and make it more stable.
