The price of oil factors in a fair bit also. When oil was $80.00 a barrel and upwards, it had an affect the choice of where large heavy items were fabricated. Steel mills in the U.S. suddenly got busy as it was cheaper to make it in the U.S. than in China w/shipping included. With this being a more expensive product than steel (by weight) and the cost of oil down significantly, shipping from Poland is reasonable. In the last couple of years, they've done lots of work in North America while fabricating in Poland.People vastly over estimate shipping costs. Moving a 40 foot container across the ocean costs maybe $1500-$2000. Add another $2000 for delivery beyond a port.
