Wellpool Co.,Ltd.

Wellpool Co., Ltd. was established on November 30, 1981, with a paid-in capital of NT$327 million, and is one of the key reinvestment projects of Goldsun Group. Wellpool was publicly listed on the OTC exchange in 2012, and its main business is the production and sale of calcium silicate boards and fiber cement boards.

Calcium silicate board: the main raw materials are pulp, cement, quartz powder, silica and calcium materials, etc.. Even in high temperature and pressure environments, the boards are fireproof, moisture-proof, durable, non-deformable, heat insulating, etc. They are suitable for wall and ceiling panels of indoor spaces.

Fiber cement board: Although the main raw materials and manufacturing process are the same as calcium silicate board, the difference lies in the higher cement ratio; the most important characteristic of this product is that it is moisture resistant and not afraid of liquids. In addition to being used in toilets, kitchens and exterior walls, it is also the main application of wet partition walls with hollow areas filled with cement grout.

Wellpools holds the management philosophy of sustainable management and green environmental protection, and is fully committed to developing products made with legally approved reusable waste materials, recycled processing water and sanding powder; therefore, Wellpool has received a number of environmental protection honorary awards, such as the Certificate of Honor for Green Consumer Manufacturers and the Environmental Protection Building Materials Seal from the Environmental Protection Administration of the Executive Yuan, the Healthy Green Building Materials, High Performance Green Building Materials and Recycled Green Building Materials Seal from the Architecture and Building Research Institute of the Ministry of the Interior, and the Ministry of Economic Affairs' official mark – inspection exempted products.

With reliable quality, affordable price, a complete range of sizes, complete distribution channels and a dedicated workforce, Wellpool products have become the leading brand in Taiwan and enjoy the honor of having the highest market share in the industry.

In the future, we will continue to expand the scale of our operations, strengthen our domestic calcium silicate board manufacturing capabilities, expand our product applications in the fields of fire protection, energy saving, and decoration, and further develop overseas markets such as China and Southeast Asia.

Goyu Building Materials Co., Ltd.

GoYu Building Materials Co., Ltd. is the first autoclaved lightweight concrete white brick producer in Taiwan and established its factory in 2018. The Company entered into supply agreements with many domestic construction firms and started to offer a new choice of partition material in the market. Besides accommodating domestic demands, various wall types can be developed in conjunction with new techniques to generate more business opportunities.


Project Awards Although relatively rare and completely imported domestically in the past, ALC bricks have been used by Europe, the US, and Japan for several years for constructing outer walls, stairs, compartments, and walls. With superb sound insulation, heat insulation, and flame-resistance performance, it has an STC rating of 45 dB and a fire rating of 2 hours, capable of retaining and insulating heat. With corresponding wall plugs, it can withstand a weight of more than 100kgf.


Easy to Install, Lightweight and Low Price Compared to other similar construction materials, ALC bricks are lighter,weighing less than a quarter of traditional brick walls, making them more labor-efficient and easy to cut. ALC bricks can be bonded together tightly with ALC brick adhesive, leaving no gaps and ensuring quick construction, thereby effectively improve constriction efficiency without increasing burden on the building, creating the most lightweight, sturdy solid panels.
