Fiber Discs & Flap Wheels
High-strength fibre-backed discs and flap wheels for grinding, deburring and polishing.

Gangying Vulcanized Fiber Disc
GY98 fiber discs - brown alumina on 0.8 mm vulcanized fiber, P24-P120, rated to 80 m/s for angle-grinder stock removal.

Gangying Flat Flap Wheel
4 in calcined-grain cloth flap wheels for polishing stainless steel, copper, metal and marble - strong cut without burn marks.

Pineapple Pattern Polishing Flap Wheel
Grooved abrasive-cloth wheels in 118 x 60 mm and 118 x 30 mm for polishing grooves, profiles and curved surfaces.
This category is for round abrasive tools used beyond simple hand sanding. It includes a vulcanized fiber disc for angle-grinder stock removal, a flat flap wheel for metal and marble polishing, and a grooved polishing wheel for profiles and curved surfaces. The buyer should match the tool to machine speed, contact shape and removal level before choosing grit.
Heavy removal on an angle grinder
The Gangying Vulcanized Fiber Disc is the most direct stock-removal product here. It is a 100 mm disc with a 16 mm bore, 0.8 mm vulcanized fiber backing and premium brown aluminum oxide grain. The listed grit range is P24-P120, and the maximum speed is 80 m/s.
That makes it suitable for weld seam and burr grinding, paint and rust removal, shipbuilding, automotive and bridge work, plus bamboo and wood products. It is not a fine polishing sheet; it is the product to quote when the customer asks for a fiber disc for an angle grinder and heavier surface correction.
Flat flap wheel for polishing without burn marks
The Gangying Flat Flap Wheel is a 4 in (100 mm) wheel made from calcined-grain abrasive cloth flaps in a long and short flap layout. Its product summary positions it for stainless steel, copper, metal and marble polishing, with strong cut and no burn marks on the workpiece.
Unlike the fiber disc, the flat flap wheel lists all standard market grits made to order. That means the quotation should start from the material and finish target, then confirm the grit mix.
Grooves, profiles and curved surfaces
For non-flat shapes, Pineapple Pattern Polishing Flap Wheel uses a grooved abrasive-cloth wheel in 118 x 60 mm and 118 x 30 mm sizes. Its applications are groove and profile polishing, curved surface sanding, metal furniture and woodworking.
Choose this line when the contact surface is a groove or curved profile instead of a broad flat plane. The listed P120-P600 range also puts it closer to polishing and controlled profile finishing than heavy weld grinding.
Ordering notes
For fiber discs, specify diameter, bore, grit and expected grinder use. For flat flap wheels, send the material - stainless steel, copper, metal or marble - and the required grit. For Pineapple wheels, include the size, color if relevant, grit range and whether the job is groove, profile or curved-surface polishing.
