🔍 What Is a Longkang Tanah / Half Round Glaze Drain?

A Longkang Tanah is a curved drainage pipe, commonly made from clay or ceramic, with a glazed surface that enhances water resistance and durability. Its half-round open-top shape allows water to flow efficiently while being easy to inspect and clean.

The glazing creates a smooth interior finish, which reduces the buildup of algae and sediment, and prolongs the drain’s life span in Malaysia’s tropical weather.
