About Us

Ching Shing Trading Sdn Bhd was founded in 1965 by Mr. Tan Hock Seng. From a small beginning, we have grown steadily over the years into a trusted supplier of various products.

Our range includes chemicals, construction materials, industrial supplies, safety equipment, waterproofing, and flooring products. One of our earliest products was oxide paint and thinner, which we have supplied since the very beginning in 1965. In 2020, we welcomed the ProZ brand into our product family, offering a full range of waterproofing, wall, and flooring solutions. We also provide waterproofing repair services.

In 2020, we set up our websites — mychingshing.com for Ching Shing’s full product range and proz.com.my for ProZ waterproofing solutions — to serve our customers better. In 2025, We have setup ProZ Waterproof Sdn Bhd. We will continue to grow, adapt, and innovate to meet our customers’ needs.
