Orangeburg, S.C.-based Cox Industries and iLevel by Weyerhaeuser have joined efforts to expand distribution of Cox fire- and preservative-treated lumber, plywood and columns in select Atlantic states under the Cox D-Blaze and Ecolife brands.

Cox D-Blaze fire-retardant treated lumber and plywood can help control the spread of flames and smoke, and Ecolife by Cox can help protect wood against fungal decay, termite damage and weathering, the company said.
