June 17 (Reuters) - Nucor Corp ( NUE ) on Wednesday forecast

second-quarter adjusted profit above Wall Street estimates,

buoyed by higher average selling prices and strong volumes in

its steel mills segment.

Firmer steel prices, underpinned by supportive trade

policies, geopolitical tensions and upcoming mill maintenance,

have tightened supply and boosted returns for U.S. steelmakers.

Here are some details from Nucor's ( NUE ) guidance:

* The company expects second-quarter adjusted profit per

share between $4.50 and $4.60; Analysts on average were

expecting $4.27 per share, according to data compiled by LSEG.

* The company posted a profit of $3.23 per share in its

first quarter, up from 67 cents per share a year earlier.

* Nucor ( NUE ) plans to release its earnings after the markets

close on Monday.
