NEW YORK — At least two more structural pipe and tube mills have raised prices following a leading move from Atlas Tube Inc. earlier this week.

Maruichi Leavitt Pipe & Tube LLC raised prices on all products by a minimum of $50 per ton effective with new orders placed after 5 p.m. CST on March 5, according to a letter sent to customers. All previously confirmed orders will be price-protected for shipments through April 1, the Chicago-based company said.

Maruichi makes structural, mechanical and HI-Y 50 pipe-size tubing, according to its website.

Montreal-based Nova Tube Inc. also followed the increase, raising its hollow structural sections (HSS) prices by $50 per ton effective March 5, AMM understands.

The increases follow an apparently leading move by Atlas Tube, a subsidiary of Chicago-based JMC Steel Group Inc., which announced March 4 that it was raising prices for HSS by a minimum of $50 per ton (amm.com, March 5).
