Industrial Heating Economic Indicators showed substantial increases in March for all four indices. All four indices moved well above the index value of 50, which indicates growth. March indicates the third month in a row that RFQs, Orders and General Health of the Thermal Processing Industry have been above 50. Three months above 50 typically signals a recovering and growing economy. March 2003 index numbers indicate the changes experienced by responding companies from February 2003 to March 2003. Change in number of Request for Proposals from February to March was 56.4, change in Number of Orders from February to March was 54.3, change in Backlog from February to March was 52.2 and expected change in the Health of the Thermal Processing Industry through April was 53.5. A number above 50.0 indicates increased activity or growth. A number below 50.0 indicates decreased activity or a decline in growth. Look for these numbers, along with historical values, on the editorial page of the next issue of Industrial Heating. Roughly 375 industry suppliers are surveyed the first full week of each month.
