ATTENTION CUSTOMERS: The global pandemic has been putting huge strains on the raw material supply chain for critical construction products. The limited supply of raw materials in the global supply chain has caused dramatic increases in costs for key elements and raw materials and is resulting in more delays with extended lead times. Most manufactures have already implemented “force majeure” and placed additional surcharges to secure their raw materials. Conspec will strive to fill everyone’s orders as much as we can in a timely manner, however with the supply chain broken, and only receiving partial inventory from manufactures with increased demands the shortages are out of our control. We apologize for the inconvenience, but Conspec will do the best that we can to fill your orders in a timely manner. Thank you for your patience and we sincerely appreciate your business in these challenging times.
