Cheers! To Building Community for 140 Years!

Building for 140 Years!

At King’s Material, we understand what we build is about more than the backyard. Or the driveway, community building, and firepit. It’s about building places to connect. To learn. To get away – with good friends and family.

We are proud to be a part of bringing people together for 140 years!

William King founded King’s Crown Plaster Co. with the company’s operations focused on dredging sand out of the Cedar River to make plaster.


The company entered the “new” ready-mix concrete industry.


The first known sale of ready-mix concrete was made in Cedar Rapids, Iowa. At $6.50 a cubic yard, the price was considered outrageous.

Early 1970s

King’s and Builder’s Material, a masonry supply and ready-mix company, merged to create Kings-Builder’s Material Inc.


Kings-Builder’s Material Inc. was purchased by Charles P. Rohde (C.P. Rohde).


Company name changed to King’s Concrete Inc.


C.P. Rohde purchased multiple concrete block companies while continuing in the ready-mix industry.


C.P. Rohde acquired Iowa and Illinois Concrete Products and renamed the company in its entirety to King’s Material, as it’s known today.


Charles A. Rohde (son of Charles P. Rohde) was named president of King’s Material and continues in that role today.


Constructed a state-of-the-art ready-mix plant at 355 50th Ave. SW in Cedar Rapids.


King’s Material moved Iowa/Illinois Concrete to a new location in Eldridge, Iowa.


Added a location in Waukee, Iowa
