Five companies supply cement, paint and cables to Kenya's building trade: Bamburi Cement, East African Portland Cement, ARM Cement, Crown Paints and East African Cables. Demand follows public infrastructure spending, housing starts and the price of clinker, coal and imported inputs, while competition from new cement plants has kept margins under pressure. ARM Cement has been suspended from trading since its administration began, so it appears on the page without a current price. Results are seasonal around the long rains, and the sector's daily volume is usually a small fraction of the market's.
