| 1. Product Introduction 
Implement national standards: DBJ01-53-2001, Structure of the material is made up of 3 portions: polyester/ glass fabric mat as basal body provides strong supporting; polymer (SBS) as modifier provides pitch better performance; isolation materials as surface coat.
2. Series of Coiled waterproof material
Classifying based on surface materials: polythene film (PE) , fine sand (S), Mineral grain(piece)materials(M)
Classifying based on body materials: polyester reticular mat and glass fiber felt (PYK), glass fiber felt and reticular cloth (GK), mixed cotton fiber non-woven fabrics and reticular cloth (NK).
