* U.S. sales up 6 pct
* Canada sales up 24 pct
Feb 11 (Reuters) - Industrial maintenance and safety products supplier WW Grainger Inc reported January daily sales growth of 10 percent, mainly driven by strong sales at its heavy manufacturing and reseller end markets in the United States.
The United States, which is the company's largest market, posted sales growth of 6 percent, while sales in Canada were up 24 percent.
Grainger, which offers products such as oil booms, degreasers and safety supplies, posted market-topping quarterly results in January, mainly helped by strong sales of oil-spill control products in the United States.
Grainger said sales growth during the first few days of February was hurt by snowstorms in the United States.
