• Our Company

    Illinois Industrial Lumber Is Northern Illinois' leading wholesaler of lumber and plywood for industrial and heavy construction applications.


    We stock over 6 million board feet of softwood and hardwood lumber, and nearly a million square feet of plywood and other panel products. If we don’t stock the item you need, let us know. We can add it to our inventory within two weeks.


    We also have a full re-manufacturing facility that can accommodate any cut-to-size order.


    At Illinois Industrial Lumber you deal directly with EXPERTS - veteran buyers and sellers. Our customers receive PRIORITY PERFORMANCE in quality, selection and delivery. Satisfaction guaranteed.


    Our Buying Power

    We buy directly from the sawmills in rail car lots, and ship single-item or custom mixed loads all over Northern Illinois. It's the kind of buying power that translates into major savings for our customers.


    With over 40 years of experience, our buyers review weekly all species of softwood and hardwood lumber produced in the U.S. and Canada. This ensures we get the best price possible without compromising quality.




    Our Location

    Our six acre facility is located in Montgomery Illinois just west of Chicago, the transportation hub of the Midwest. We have a full acre under roof for clean, dry lumber storage.


    With our centralized location and our own fleet of trucks, we have the ability to deliver full and partial custom loads throughout Illinois, Wisconsin, Indiana and Iowa. Many orders are shipped the next day.​


    Our location on the Burlington Northern Santa Fe Rail Hub allows us to economically purchase forest products from all producing regions of North America. This enables us to provide more options at increased savings to our customers.

  • Wood Byproducts

    At Illinois Industrial Lumber nothing goes to waste. We use wood scraps to heat our warehouse and sell the leftovers to local mulchers. All of our sawdust is sold to local farms for animal bedding.

    Wood Scraps

    Each winter we use the wood scraps from our re-manufacturing facility to heat our warehouses. Instead of expensive gas furnaces, our wood stove can produce enough heat to keep 15,000 square feet nice and warm. We also sell the leftover wood scraps to local mulchers.

    broken image


    Our re-manufacturing facility produces thousands of pounds of sawdust each week. Instead of filling our landfills with this useful byproduct, we refine it and sell it to farms for animal bedding. Sawdust also makes a great sweeping compound because of its highly absorbent properties. Try some on your warehouse or factory floor today!

    For more information on how to purchase Wood Scraps or Sawdust for your business, call 630-896-7500.
